Description

The method utilizing modified husky body Desert Control

Technical field

The present invention relates to the husky utilization of resources and desert, desert treatment field, utilize particularly to one and have The method of the modified husky body Desert Control of earth characteristic.

Background technology

(1) desert, desertification and harm thereof

Desert and desertification are the great environmental problem that face of mankind nowadays is the severeest.

Whole world land surface is 1.62 hundred million square kilometres, takes up an area the 30.3% of the ball gross area, Qi Zhongyue 1/3 (48,000,000 square kilometres) are Desert Area arid, semiarid, and annual with 4～60,000 square kilometres Speed expandings.And desert area has accounted for the 10% of the land gross area, also the soil of 43% is faced with sand The threat of desertization.

China is that desert, the world is distributed one of most country, is also seriously to be endangered by dust storm and desertification in the world One of country of evil.The numeral that China national forestry bureau announced in 2011, whole nation sandy land area 173 Ten thousand square kilometres, accounting for the 18% of territory total area, wherein desert area has 80.89 ten thousand square kilometres, accounts for The 8.4% of area.

Harm in Desertification Process include stream and sand dune reach cause to farmland cover, river, reservoir, Water channel blocks, and highway buries, and also makes whole environmental degradation, loss of land resource, and related draws The regional economy risen is slow, society is unstable etc. society, economic problems.

Desertification directly results in the precious land resource that can directly utilize and drastically reduces.Desertification is directly led Causing land deterioration, Soil structure destroys, the nutrient loss of soil, and these recover to need many decades, hundreds of Year, the most thousands of years.The deterioration of grasslands that desertification causes, make the advantage grass seeds being suitable to livestock edible by The fewest, even completely lose, herbage becomes short, sparse, and yield substantially reduces, grassland capacity for raising livestock on the grasslands Greatly decline.Desertification causes river, reservoir, water channel to block, such as, and the average annual sediment transport in the Yellow River 1,600,000,000 tons, The most just there are 1,200,000,000 tons from Desertification.Desertification causes railway bed, bridge, culvert in some areas Hole is damaged, and makes highway subgrade, road surface sand, forces highway communication to be interrupted, and even makes highway discard.Due to Dust storm is pressed hard, and thousands of herdsman is forced to move to alien land, becomes " eco-refugee ".China national forestry bureau The data provided show, 20 end of the centurys, and desertify the annual speed expanded with 3436 square kilometres, every 5 years An area being equivalent to Beijing's administrative division size is just had to lose value because of desertification, the whole nation The population affected by desertification reaches 1.7 hundred million.Desertification of land, desertification not only deteriorate ecological environment, decline soil The ground productivity, threatens rivers safety, and it is poor to aggravate husky district.

Desertification causes ecosystem and natural environment deterioration, and natural disaster takes place frequently, be facing mankind the most One of serious disaster.Natural, ecological is the integral framework that a various factors mutually restricts, will be according to necessarily The poised state that keeps relative stability of rule.Desertification greatly changes the physical features on earth's surface, land, Destroy Radiation budget balance, induction weather and environmental change, cause the soil erosion of Desertification More serious, green vegetation drastically reduces, and ecological environment drastically deteriorates, and rare animals and plants disappear or extinction, Diversity of organism suffers serious destruction.After unusual weather conditions and ecosystem are destroyed, cause desertification Speed aggravation, both form vicious cycle, are degrading natural environment further, make the people of Desertification Lose the basis depended on for existence, and cause the natural disaster in other area.According to monitoring, China city Air pollutants are mainly finely ground particles, and this is closely related with desertification.Dust pollution wide geographic area people The productive life environment of the people, sandstorm is frequent, have impact on people's health.

It is huge that the seriousness of Deserts in China also resides in the population statistics involved, and it directly or indirectly affects closely The life (account for the whole world and perplexed the 40% of population by desert and desertification) of 400000000 people.China's desertification harm Direct economic loss about 64,200,000,000 yuan is annual, and the indirect economic loss that desertification and derivative harm thereof cause is about 288900000000 yuan annual.If countermeasure without effectively preventing, be in the Urumchi of desert band, Lanzhou, Xi'an, The big cities such as Yinchuan, Taiyuan, Huhehaote, Beijing, Tianjin, can become city, desert one by one eventually, Large quantities of common people will become eco-refugee.

(2) desert and the measure of desert treatment and achievement

The fundamental way of Desertification Control is the character according to hazards of sand storms, takes various technical measures, weakens The wind speed of near surface formation, reduces the sedimentary loading in air-flow, delays or stop sand dune to move forward, with reach weakening or Avoid the purpose of hazards of sand storms.For a long time, the measure of harm (sand control) that prevent and control sandy storm, Chinese scholars It is summarized as engineering sand control (mechanical) measure, controlling sediment by plant measure and chemistry sand control measure three major types.Plant Thing sand control measure and engineering sand control measure belong to reduction wind speed, weaken stream intensity, and chemical sand-fixing is then Consolidation Shamian Island, controls Shamian Island wind erosion process development.

Vegetative sand control is also called sand consolidation with biologic, is by the means such as fencing and serike, reaches to prevent and treat desert, Stablize oasis, improve husky district's environmental quality and a kind of technical measures of productive potentialities.Vegetative sand control why can Enough tackling quicksands, one is owing to psammophytes has the root system of prosperity, can consolidate the grains of sand about, in addition The accumulation of dry branches and fallen leaves, is conducive to organic gathering, promotes the pedogenesis of sand, change sand ground after rotting Character, makes drift sand tend to stable；Two be due to serike on sand dune after, add the roughness on earth's surface, Thus also increase the resistance to wind, reduce wind speed, weaken and inhibit stream activity.

The main method of vegetative sand control includes: (1) envelope sand-base cultivation grass, protects natural vegetation；(2) afforestation Fix the sand；(3) desert edge wind prevention and sand resistance forest belt is built；(4) the internal shelter belts to protect farmland net in oasis is built.

Vegetative sand control can improve the ecological condition in vegetative coverage sand territory, promotes that sandy plant community is to good direction Development, forms stable ecosystem, is conducive to increasing bio-diversity.

But, desert area drought, cold and hot drastic change, wind great Sha is many, and natural environment is the harshest, always Being not suitable for the growth of plant on body, therefore, the effect of vegetative sand control is limited by desert characteristic and natural environment System, particularly under conditions of without irrigating, such as the time arid especially, due to water deficient, can make cultivation The plant undergrowth planted or mortality.

Sand-prevention engineering measure is to utilize weeds, crotch, and cob wall or other structures etc. set air partition on drift sand Or covering Shamian Island, prevent Sand Movement.Engineering sand control measure has fast feature of producing effects, but the protection phase is short, The most often it is applicable to the traffic line of drift sand serious harm, important industrial and mineral base, farmland and the area in residential area, And use during for protection sand-fixation plant growth.Main method has: the husky fence (high vertical sand barrier) of resistance, machinery Sand-protecting barrier (setting straw checkerboard barrier sand-protecting barrier), clay fix the sand, transporting sand engineering (lower wind-guiding, feather row and sediment transport section etc. Type).

The mechanical function principle of engineering control measure, is all the resistance of motion by increasing stream, and retardance disappears Can, make it slow down and promote the deposition of sandy soil granule, being a kind of provisional measures for sand prevention, for drift sand Harm, functions only as fixing the sand the effect of " controlling table ".

Chemical sand-fixing be moving dunes () upper spray chemical bonding material, formed on drift sand surface and cover Layer, or penetrate in the sand of top layer, loose sand material bonding is got up to form bonding course (duricrust), thus prevents wind Sand material is blown and is raised and carry by power, reaches tackling quicksand, prevents and treats the purpose of sand damage.Chemical sand-fixing is the most multiplex The area of heavy economic losses is caused, (such as airport, traffic line (railway, highway), military affairs in hazards of sand storms Facility and important industrial and mining area), and often match with vegetative sand control, complementary and transitional as vegetative sand control Measure.

The effect of chemical sand-fixing effect, not only with the character of drift sand surface particles (such as chemical composition, mechanical group Become) relevant, and also (as big in molecular structure, molecule with the physicochemical properties of chemical sand fixing material itself Little, viscosity, absorption affinity) etc. relevant.Chemical sand fixing material conventional as asphalt emulsion, oil Ye Yan ore deposit liquid, Synthetic resin, synthetic rubber etc., it is possible to use some natural organic matters, such as brown coal, peat, municipal refuse Refuse, resin etc..

Asphalt emulsion is that our times various countries apply widest material in chemical sand-fixing engineering.But, breast Change Colophonium the most also there is also because of the asphalitine in Colophonium and resin be prone to by the oxygen in air, light, heat, Moisture and microorganism etc. destroy, and oil content declines.The gradually aggravation of this change, causes asphalt performance to degenerate, As softening point raises, needle penetration declines, and ductility reduces, and causes unity layer slowly to become fragile, harden, and loses Plasticity, occurs aging, so that finally ftractureing and being destroyed by wind sapping, loses sand fixation.

(3) desert and the basic difficult and problem of existence of desert treatment

The ideal goal of control of desert is, desert can either be made stable, again can growing plant, namely make " change oasis, desert ".But, the husky body in desert is discrete particle, and the basic difficulty of control of desert is, Husky body in desert easily moves, is difficult to water conservation and stores nutrient.The most current sand control measure, people are not Difficult discovery, existing desert control method the most fundamentally solves desert and easily moves, is difficult to water conservation water-retention And store this two hang-up of nutrient.

Existing desert control method is to fix the sand to be main, no matter uses engineering (mechanical) measure, plant to arrange Executing and chemical, it, not from the attribute improving Desert Sand body itself, only avoids the movement of husky body to make Become harm, therefore from its method and mode, still fall within passive sand control, can to a certain extent or Overcome the flowability problem in desert in the short term, be but difficult to fundamentally to solve desert be difficult to water conservation water-retention and Being difficult to store a difficult problem for nutrient, " change oasis, desert " that distance it is desirable to still has bigger distance.

1. engineering (mechanical) measure can temporarily change the physical aspect (naturally occurring mode) that desert exists, It is a kind of provisional measures for sand prevention, for the harm of drift sand, functions only as fixing the sand the effect of " controlling table ", Desert is tamed by of short duration, it is impossible to reach the effect of " effecting a permanent cure ", long-time after, it still can be recovered in desert Carry out appearance.

2. chemical sand-fixing is the surface using sand-consolidating agent to be sprayed on husky body, to reach the purpose fixed the sand, sand-consolidating agent The surface grains of sand are retrained, forms a kind of containment vessel of stablizing on grains of sand surface, and then make husky body stable, do not flow. But, chemical sand-fixing materials often uses spray method to be formed, and is only capable of being formed in the scope that husky surface is the thinnest Constraint, the constraint that surface is formed once is destroyed, it may be difficult to recover, and chemical substance weatherability determines Its sand control can only temporarily block the flowing of husky body, it is impossible to reaches the purpose of long-term stability, and its cost puts into height.

The earliest, spraying the sand-consolidating agent used is often emulsified asphalt, and after sprinkling, sand dune surface skining is the thickest Spending little (usual 2～3cm), after using the several years (usual 3～5 years), bonding course starts to crush；Meanwhile, The emulsified bituminous materials sprayed, to environmentally undesirable, and itself is not the nutritional labeling of plant growing, therefore its Effect is only fixed the sand；Additionally asphalt material aging is poor, will not have sand fixation after break inactivation.

At present, it has been developed that many macromolecular sand-fixation agents, after sprinkling, sand dune surface skining thickness is thin (logical It is often 0.2～0.5cm), surface retains few, and dried surface is the most cracking；Meanwhile, after sand-consolidating agent sprays, It is generally required to certain time consolidation, being difficult to meet water-dispersible again or dissolve after consolidation, its water retention is the most logical Cross close top layer part hole, part blocks underground evaporation of water and realize, its material itself there is no water conservation Effect；Further, cortex itself does not have water-retaining property, thus can not protect containing nutrient, it is impossible to adapt to the general of plant All over growth.So, the feature of sand-consolidating agent and fix the sand its long-term behaviour fixed the sand of structures shape of layer and be difficult to To basic assurance.

3. the applicable elements of vegetative sand control is frequently subjected to the restriction of weather and environment

Vegetative sand control utilizes plant top resistance sediment barrier husky, utilizes the root of plant to fix the sand, it is possible to a certain degree Upper change micro climate and micro-soil environment, but, the basic difficulty of vegetative sand control is that desert itself is unfavorable for Plant growing, as unstable in desert and wind-driven sediment is frequent, desert is barren, water deficient and be difficult to water conservation, Plant is all had a negative impact by homoiothermics etc..

Wind-driven sediment can make plant by deflation, sand buries and sand cuts harm, and wind-driven sediment can use engineering protection Measure and chemical sand-fixing solve, but, desert water deficient and be difficult to the basic difficult problem of water conservation water-retention, make biography The suitability of system vegetative sand control receives greatly restriction.

In sum, it is desirable to obtain a kind of control of desert measure, make husky body have the same stability of soil, Water-retaining property, breathability also have the function storing nutrient, it is, make husky body " soil ", from root Solve husky body in basis easily to move, be difficult to water conservation water-retention and a difficult problem for storage nutrient so that it is plant preferably is raw Long, and then fundamentally improve the form of husky body and carry out control of desert.

Comparing with other control of desert measure of prior art, the present patent application has the advantage that

1. compared with fixing the sand with engineering

Engineering Sand-fixing Measures changes the roughness on drift sand formation surface, do not improve husky body self structure composition and The way of restraint, only serves the effect that physics improves.The present invention improves the granule group of husky body by bonding material Become rule, while improving the way of restraint of husky body granule so that it is structure has water conservation, water-retention, guarantor Holding the function of nutrient, it is, make husky body " soil ", this modified husky body is more suitable for plant growing.

2. compared with chemical sand-fixing method

The present invention is embodied in many aspects from the different of chemical sand-fixing.

First, present invention achieves " soil " of husky body, the method that realizes with chemical sand-fixing and make apparatus There is fundamental difference.

The present invention uses will be had water conservation, bonds and stores the constraint material of the effects such as nutrient function and husky body The method of mix, its effect can realize " soil " of husky body, and can plant various plant, and chemical Fixing the sand only by the method for surface spraying chemical sand-fixing materials, its effect is only capable of realizing the consolidation of surface sand body, anti- The movement of the most husky body.Constraint material and husky body mix under certain condition that the present invention uses form modified husky body, The modified husky body formed has water-retaining property, function is supported in storage, and changing of being formed of the constraint material that uses of the present invention Property sand body in dry, wet two states, all there is good stability, the constraint of formation can be according to dry and wet state Change and reconfigure, change.The present invention is the overall constraint system changing husky body, and only strengthens husky body surface The constraint system in face is essentially different.The present invention is used for desert, can be by husky surface 3～50cm Husky system be made modified husky body, and then make the husky body in desert be difficult to flowing, be provided simultaneously with plant growing indispensable Moisture and nutrient, reach the purpose of basic sand control.Chemical sand-fixing measure is by spraying chemistry in husky surface Sand-consolidating agent, is increased the constraint of surface sand body by the infiltration (length of penetration is generally less than 3cm) of sand-consolidating agent By force, only changing the way of restraint of husky surface, its degree of depth is the most shallower, and its constraint has irrecoverability, Impact on natural environment is relatively big, and ordinary disbursements is high.The effect of cured layer itself is single, can only provide consolidation Effect, does not have the function of water conservation, water storage, and nutrient.

The present invention and the intensity mechanism fundamental difference of chemical sand-fixing.

Chemical sand-fixing is the consolidation by realizing surface sand body at husky surface sprinkling chemical consolidation material, for Playing the effect of the overall husky body of consolidation, surface sand body requirement of strength is higher, comprcssive strength even to exceed 1MPa could really prevent destruction and the movement of husky body, and the present invention is then in the range of certain thickness, by sand Body with there is bonding, the constraint material of water retaining function mixes, it is achieved the constraint each other of overall husky body, Preventing the movement of husky body, the constraint of husky body reality is not required to the strongest, and this point can carry out analogy from soil, From the point of view of test, after using the present invention, husky body is in a way, it is achieved that " soil ", although pass through Regulation constraint material type and consumption, can accomplish sufficiently high by the surface consolidation strength of husky body completely, but Test and analysis show, the surface comprcssive strength of husky body can play the effect of stabilized sand body in the least scope, Chemical sand-fixing effect can be reached, " soil " of husky body, Ji Ketong in the range of achieving again certain thickness Time planting plants, it is achieved fix the sand and eucyclic purpose.

Compared with chemical sand-fixing, the present invention also has the restorability of destruction.

The performance of the constraint material that the present invention uses determines the feature of the restorability of modified husky destruction, this The constraint material that invention uses is dissolvable in water in water, and the liquid object after dissolving and husky body mix form modified husky body After, moisture therein is difficult to lose, even if after loss of water, if meeting water again, constraint material can dissolve again Yu Shuizhong, re-forms the modified husky of same purpose, and this process can the most repeatedly, shape the most of the present invention The modified husky body become has the restorability of destruction, but chemical sand-fixing is the most entirely different, and chemical sand-fixing uses Material behavior determines the irrecoverability of destruction, and chemical sand-fixing is in order to ensure surface sand body consolidation, often Use intensity higher and there is the sand fixation material of reversal properties, but surface strength is once destroyed, it is impossible to Recovering on original base, sprayed on material could recur and arrive consolidation the most again, and otherwise sand body in surface breaks again After Huai, husky body below is exposed to surface again, accumulates over time, and original effect of fixing the sand will progressively Lose, fix the sand purpose and effect just cannot ensure.

As can be seen here, the present invention makes the method for modified husky body and by the infiltration of chemical sand-fixing materials by mix The method fixed the sand is inherently different.

3. compared with vegetative sand control method

The present invention with the fundamental difference of vegetative sand control is, vegetative sand control can only " be taken stopgap measures ", and the present invention be from Fundamentally change husky volume property, it is achieved husky body " soil ", thus realize vegetative sand control truly, Therefore the present invention is only the arranging of " effecting a permanent cure " of control of desert.

Vegetative sand control utilizes vegetation rhizome that the mode that husky body retrains plays the effect fixed the sand, but husky body is certainly Body character is not appropriate for plant growing, and moisture easily runs off, and husky body also cannot be stablized, husky body under wind effect It is mobile that frequently plant is difficult to grow, though short-term plant growing, in the presence of a harsh environment, if moisture can not have Effect preserves, and plant is also difficult to continued growth, the most withered, and therefore the effect of vegetative sand control is not only by locality The restriction of weather conditions, is also difficult to realize its effect fixed the sand for a long time.The present invention then has root with vegetative sand control This difference.The present invention is the basic point from vegetative sand control, and the performance improvement of i.e. husky body is started with, it is achieved husky " soil " of body, not only has the effect of stabilized sand body, also makes husky body have water conservation, water-retention, storage The function of nutrient, makes husky body possess the condition of plant growing, it is achieved that husky body stable and plant growing Condition, plant growing also could really realize, and therefore for certain angle, the present invention is only real meaning Vegetative sand control.

In order to contrast the effect of the present invention and vegetative sand control, the present invention has also carried out contrast test.By this Bright method takes sodium carboxymethyl cellulose as having the material of bonding, water retention in modified sand, thus Formed modified husky, by modified husky and moistening common husky body making simultaneously in outdoor crushed stone, placement thickness Being 15cm, and dispense multiple Semen Allii Tuberosi and grass seed on surface respectively, after 1 day, common husky body becomes dry, modified Wetting state is remained in that behind husky some skies, and on the premise of not watering, the grass seed on modified husky surface and dish Seed germinates, but the grass seed of common husky surface and Semen Allii Tuberosi are withered again after germinateing and thirst, planting of modified husky upper plantation After thing, once water and can meet the water demand of plant in interval for 10-30 days, the seedling on modified sand Growing up through 2 years, reached about two meters, Fructus Lycopersici esculenti and the dish Seedling of modified husky upper plantation can normally eat, Suitable with planting plants growing way in soil.After planting 1 year, sand body connection is netted by root system of plant, and soil Outward appearance, character are all without difference, and the plant rotted former years can be described as again nutrient, and husky body is stable further, changes Property husky plantation effect form benign cycle, sand fixation is the most feasible, economical, also makes desert become fertile soil It is possibly realized.

4. compared with other method: such as water-absorbing resins

Super absorbent resin is containing strongly hydrophilic group, is generally of the macromolecular material of certain degree of cross linking. Super absorbent resin is water insoluble and organic solvent, and water absorbing capacity is generally the hundreds to thousands times of own wt. After the water suction of this material swelling for hydrogel, after pressurized, water is not easy to extrusion；Resin is dried, can be the most Secondary water suction, its moisture overwhelming majority absorbed can slowly discharge, and utilizes for plant absorption.

The constraint material that super absorbent resin and the present invention use has essential distinction.The constraint material of the present invention There is caking property and adhesiveness, there is water solublity, the caking property of dependence constraint material and adhesiveness and the husky bodily form Become constraint.This constraint can present different character along with dry, wet change, and constraint also can reconfigure.

5. the present invention has significant economy, exploitativeness and the feature of environmental protection.

First, the modified husky body that the present invention is formed is compared with existing sand fixing technology, and its disposable investment construction becomes Originally there is certain economic benefit.The constraint material that the present invention uses can be formed under conditions of volume is minimum Meet the modified husky body required, as take some solid organic materials that can be dissolved in water include natural polymer and One or both and above mixture in its modified solid matter and synthesis macromolecule solid matter；As: Polyvinyl alcohol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl first One or both and above mixing in base cellulose and cellulose ether or copolymer, constraint material only accounts for sand A few one thousandth of body weight ratio, and material is for commonly using chemical materials, material cost is relatively low, therefore from former Say in reason that material cost is relatively low, and construction method is the most relatively simple, only with the common process such as stirring, machine Tool, labour cost are relatively low, and therefore comprehensive method of investment cost will have considerable economy.With carboxymethyl cellulose As a example by element sodium, adding 20kg sodium carboxymethyl cellulose material in 1 cubic meter of water, market unit price is 10 yuan/kg； Correctability sand body about 4 cubic metres, it is considered to artificial, machine cost 100 yuan, then modified husky body 1 cubic metre, Cost is 75 yuan, is layed in husky surface by 10cm, and 1 cubic metre of modified husky body can lay 10 square metres, then The disposable input cost of modified husky body Desert Control is 7.5 yuan/square metre.

Secondly, different from conventional sand-fixation method, the modified husky body that the present invention is formed has recyclability, once After investment construction, modified husky body can plant various plant, and modified husky physical ability stablizes root system of plant, and plant Root system stabilized sand body the most in turn, and the rhizome, the leaf etc. that rot again can be as nutrients, for husky structural reform appearance Becoming benign cycle, desert will actually change available class land resource, have once investment long-term gain Feature, therefore its indirectly economy by inestimable.

Exploitativeness of the present invention is stronger.The present invention uses material to be existing chemical industry common used material, such as poly-second Enol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl methyl are fine Dimension element and cellulose ether are the thickening material that chemical industry is conventional, and production method is simple, feasible, and cost is relatively low, The construction method that additionally present invention uses is simple, and master operation is point preparation being spread on husky liquid solution and modification sand The mix of body, therefore the present invention is prone to grasp, and implementation is stronger.

The present invention also has the feature of environmental protection, the constraint material of the present invention, can use the material rich in nutrition, its Itself can be the growth necessary nutrient of offer of plant, it is possible to add the necessary nutrient of plant growing wherein. The dry and wet that husky body is retrained according to husky body by the present invention can reconfigure, change, and has restorability.This The constraint material of invention uses conventional material, and such as sodium carboxymethyl cellulose, itself is also food additive, Environmentally safe, expense is low, it is easy to implement.

In summary it can be seen, the technical measures of present patent application achieve husky body soil from principle, can be from Fundamentally play the effect of sand control.

Modified husky body in two kinds of methods does not has essential distinction, regardless of order by merging, the tool ultimately formed Material in the cementitious and solution of adhesiveness has thickening property and water solublity, could obtain caking property and viscous The solution of attached property, it is achieved goal of the invention；The general solution requiring there is caking property and adhesiveness and husky (mixing Order does not limits) the modified husky body that formed after mix has the feature of plastically deformable or forms diluter shape After state and moisture evaporation, there is plasticity.

In the present embodiment, in step b, paving thickness is more than 5cm；There is enough intensity to be applicable to sand Unconcerned improvement.

In the present embodiment, after there is between the grains of sand of modified husky body the water evaporation in caking property and adhesiveness solution, The grains of sand are bonded together by the solid organic mass-energy that can be dissolved in water therein；Described have caking property and adhesion Property solution in water evaporation after, the weight ratio between the solid organic materials that can be dissolved in water therein and husky body is 1:30-8000；The modified husky body soil formed in this proportion can be better achieved the modification of husky body, its Characteristic more can press close to the soil of applicable plant growing.

In the present embodiment, between the grains of sand of modified husky body, there is interconnected pore and dead-end pore；The present invention changes Property sand body porosity can be more than the porosity of discrete husky body, also greater than the interconnected pore rate of normal soil, to mend Repay the grains of sand and be more than soil particle, and make husky body have soil characteristic；This hole can store moisture, nutrient and Air so that it is have more soil characteristic, adapts to arboreal growth.

In the present embodiment, in step a1, the described solid organic materials that can be dissolved in water include natural polymer and One or both and above mixture in its modified solid matter and synthesis macromolecule solid matter；As: Polyvinyl alcohol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl first One or both and above mixing in base cellulose and cellulose ether or copolymer；With low cost and play The solid matter of expectation function is main；The solid organic materials that can be dissolved in water is not limited to above-mentioned listed solid-state Material, has the solid matter same or like with listed solid matter character and all can realize purpose, and premise is The solution with caking property and adhesiveness ultimately formed, and this solid matter has thickening property and water in water Dissolubility, could realize goal of the invention, not repeat them here.

In the present embodiment, in step a1, be also added with being scattered in the natural polymer in described solution and One or both and above mixture in modified material and synthetic high polymer matter.

In the present embodiment, in step a2, it is also added with organic polymer auxiliary agent, little molecule auxiliary agent, surface activity Agent, inorganic active powder or powder material, inorganic inactive powder or powder material, solid substance and PH One or both and above mixture in value Auto-regulator；Organic polymer auxiliary agent, little molecule auxiliary agent and Surfactant may select such as glycerol, tetramethylolmethane, triethanolamine, alkyl carboxylate, alkyl sulfate, The primary ammonium salt of alkylphosphonic, alkylsulfonate, alkyl trimethyl ammonium chloride, alkyl, the secondary ammonium salt of alkyl, alkane Base tertiary amine salt, alkyl quaternary ammonium salts, beet alkali surface activator, amino acid type surfactant, poly alkyl alcohol Oxygen vinyl Ether, alkylphenol polyoxyethylene, polyoxyethylene alkyl amine, polyoxyethylene alkylamide, polyhydric alcohol Type surfactant etc.；Improve or regulation solution caking property in modified husky body, adhesiveness, toughness, Levelability, dispersibility, water solublity, water absorption, foaminess, defoaming are or/and construction workability etc.；Such as Inorganic active powder or powder material and inorganic inactive powder or the optional such as kieselguhr of powder material, Bentonite, white carbon, flyash, Pulvis Talci, calcium powder and other inorganic powder etc., improve or regulate modification The grating of husky body or the modified husky water suction of body, water conservation, toughness reinforcing performance；Solid substance can be that Sha Tizhong carries Some entity foreign material, or the later stage add, such as rigidity or flexible fiber, fabric, rattan, film tape, Sheets etc., improve or regulate the modified husky stability of body, crack resistance or toughness；PH value Auto-regulator, such as adds Acid adding, alkalescence Auto-regulator, such as Calx, Cosan, ferrous sulfate powder, vinegar liquid, pine soil, phosphorus Acid dihydride potassium solution and other improve or the material of the modified husky body Acidity of Aikalinity of regulation.

The organic polymer auxiliary agent added, little molecule auxiliary agent, surfactant, inorganic active powder or powder On grain material, inorganic inactive powder or powder material, solid substance and pH value Auto-regulator are not limited to Stating listed material, have the material same or like with listed physical property and all can realize purpose, premise is right The soil characteristic of modified husky body has facilitation, does not repeats them here.

Certainly, water-absorbing resins, modified starch also can be added, modified cellulose, polyacrylate and altogether Polymers class, polyacrylamide and copolymer analog thereof, polyvinyl alcohol, polyethenoxy ether class, soybean protein class, Fibroin class, pectin, alginic acid, chitosan and modifier thereof, blended, the high-hydroscopicity of super absorbent resin Resin and the complex etc. of inorganic matter gel, improve water suction and the storage capacity of modified husky body；Or it is added with Machine fertilizer, inorganic fertilizer and composite organic-inorganic fertilizer, such as compoiste fertilizer, nitrogenous fertilizer, phosphate fertilizer and potash fertilizer or binary Compound fertilizer nitrogen phosphorus, nitrogen potassium and the binary compound fertilizer of phosphorus potassium and N P and K NPK etc., increase modification The husky character of body, level etc. of increasing soil fertility, all can improve the combination property of modified husky body, be suitable for Plant growing.

Experiment shows, it is possible to is repeatedly dissolved in the water and has thickening property and water solublity in water, then can The material that enough formation has caking property and adhesiveness solution has multiple, does not repeats them here, such as: poly-second Enol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl methyl are fine One or both and above mixing in dimension element and cellulose ether or copolymer；After being dissolved in the water, no Be only capable of in the case of bigger volume (solid content after moisture evaporation) (such as mass percent be 5～10%, Even 10～20% or more than 20%) solution with caking property and adhesiveness is made, and can be relatively In the case of little volume, such as less than 5%, even less than 1%, make and there is the molten of caking property and adhesiveness Liquid.Also can add some auxiliary agent during use, improve or improve caking property and the adhesiveness of solution further；Nothing Machine material can also compound with organic substance, and to obtain, we are desired has the molten of caking property and adhesiveness Liquid.

The solution (containing nutrient) described in Sha Tiyu with caking property and adhesiveness is mixed and after mix, just can Enough formation has soil property, granule+constraint+hole modified husky body (can also be that sand, water and energy are molten Solid organic materials in water is formed by different order mixing mix)；When wet, moisture and nutrient storage In the solution and solution sticks in the hole between husky body granule, so, modified husky body not only has guarantor The character that water storage is supported, and there is the viscoelastroplasticity character as wet soil；When dry, originally dissolved Bond after the solid organic materials consolidation that can be dissolved in water of Yu Shuizhong the granule between modified husky body, so, change Property sand body there is the character of the porous solid as dry soil, and, the material after described consolidation can Absorb moisture and be again dissolved in the water, so, modified husky body also has the energy of absorption moisture (containing nutrient) Power.

In the modified husky body structure of granule+constraint+hole, owing to making the grains of sand produce adhesion (cohesive strength) Constraint this as added enter material (being solution when moisture is big, moisture hour is gradually converted into solid), material After filling pore, the hole of modified husky body can be less than the hole of unmodified front discrete husky body, but, by After the solution mix that Yu Shati and material are formed, it is no longer the most directly to contact between the grains of sand, contact point Between have described material so that the spacing between husky body increases that (and the moisture in the solution that material is formed steams After Faing, the solid content of material itself is less, and its ratio occupying hole is little), therefore, between granule The change of " loose " " tightly " of contact, the hole of modified husky body can also be more than being even far longer than before modified The hole of discrete husky body, to sum up, the hole of modified husky body both can be less than, can also more than before modified from The hole of loose sand body, experiment shows, the porosity of modified husky body can change between 10～80%, this hole Gap rate scope is not only greater than discrete husky body, and more than almost all kinds of soil, this indicates that, we The porosity of modified husky body can be regulated by different proportionings and structure, make husky body contain it is desirable that water Point, nutrient and air.Moreover, in the pellet pores structure of modified husky body, both there is interconnected pore, Also having dead-end pore, wherein interconnected pore rate is 5-70%, and modified husky body can be by interconnected pore with outer There is the exchange of water and air in portion.

Due in the structure of granule+constraint+hole in modified husky body, the restraining forces of constraint material (material) with And the porosity of the husky body of modification can regulate, so, after the moisture evaporation in modified husky body, the picture of formation is dry The intensity of the porous solid that earth is the same can regulate in a scope the biggest, and intensity is at below 10Kpa Time, modified husky body is the more loose solid of ratio, when intensity is between 10～50Kpa, modified husky body be molding relatively Good loose solid, after intensity is more than 50Kpa, modified husky body gradually toughens, in order to be done Time harder modified husky body, can be retrained by regulation and porosity so that it is intensity reaches more than 200Kpa.

The modified husky body become by sand, be exactly one " native " on mechanical state, have rheology (time wet) and Solid (time dry) two states, and, " native " of dry solid state can convert after absorbing moisture For " native " of wet rheology, and " native " of wet rheology can be converted into after moisture evaporates " native " of dry solid state, by the constraint between regulation granule and space, we can regulate modified husky The rheology (such as viscoelastroplasticity) of body this " native " or solid property, obtain from " sandy soil " to " loam " Between " clay " " native " of variety classes plant growing various, suitable；Therefore, by this Sand is become " native " by bright modified husky body, for available husky body, the mode of desert.

According to modified purpose, construction requirement or the difference of economy, low viscous solution (viscosity can be prepared Below 100mpa s), it is also possible to (viscosity is at 100mpa s～5000mpa s to prepare moderately viscous solution Between), can also configure full-bodied solution (viscosity be more than 5000mpa s) and sand body mix and formed and change Property sand body.

After preparation forms modified husky body, due to modified husky body and the extraneous exchange that moisture can occur, so, In modified husky body, the water content of solution can change, and then, the viscosity of the solution in modified husky body except with The material behavior of the material added is relevant and outer, also relevant to the change of water content, but described in there is bonding Property and adhesiveness solution in moisture evaporation after, the solid content of material is geostationary, so we are permissible Using the weight ratio of the material that added and husky body as controlled quentity controlled variable, determine the volume of described material.According to material The difference of character, add material in the solution with caking property and adhesiveness in modified husky body kind and Volume can select in a bigger scope, after moisture evaporation, and the material added and modification sand body When weight ratio is in the range of 1:30-8000, we all can obtain requiring based on different modified purposes and expecting The modified husky body obtained.

The modified husky body obtained based on particle confinement principle, its constraint can not only produce between sand grain Adhesion, and adhesion can be produced between husky body and other material, so Sha Tizhong is doped with in right amount Gravel, plant roots, stem, skin, animal wastes, corpse residue etc. time, will not change and have in its main body There is the character of soil characteristic, so, method based on particle confinement, we are possible not only to transform simple sand Or sandy soil, and Gobi desert etc. can be transformed and contain the husky and wasteland of other material；Utilize this character, we Even can add rigidity or flexible fiber, fabric, rattan, film tape, sheet etc., improve or regulate modification The husky stability of body, crack resistance or toughness；Various fertilizer, the nutrient that can be dissolved in the water enough is added in decapacitation Outward, other fertilizer also is able to be constrained in modified husky body, provides nutrition for plant growing；We are all right Add water-absorbing resins, acid-alkali accommodation material etc., improve the modified husky water suction of body, water retention property or modification The soda acid performance of husky body.

Above-described embodiment can not all of alternative material of limit, ratio is if dissolving and can being dissolved in water in water Solid organic materials also have a lot, do not repeat them here, all can realize goal of the invention, certainly, with low one-tenth Basis the material playing expectation function are main.

Certainly, the order by merging of said components can not limit protection scope of the present invention, can by husky, water and Can be dissolved in the solid organic materials of water mix in any order and mix and formed, after mix, described can be dissolved in The solid organic materials of water be dissolved in the water and formed there are the solution of caking property and adhesiveness the adhesion grains of sand and Form the modified husky body with pellet pores structure；Moisture in the described solution with caking property and adhesiveness Can stick between the grains of sand with solution；After moisture evaporation in the described solution with caking property and adhesiveness, Material therein can again be dissolved in the water and be formed and have the solution of caking property and adhesiveness and glue after meeting water The even grains of sand；Further, being experimentally confirmed, the result of gained there is no substantially change.

On the husky body of this modification during planting plants, whole modes of planting plants in prior art soil can be used, Including membrane curing, booth growth, with the outside severe natural environment of opposing；In a word, plant with in soil Plant does not has internal to distinguish, and does not repeats them here.

Contrast shows, after the described liquid with caking property and adhesiveness is formed modified husky body with sand mix, Pave structure sheaf again that formed in common husky surface, and described liquid is sprayed directly on common husky surface And the surface layer formed has the difference of essence, it is embodied in:

First, it is achieved fundamental difference in principle.

From the composition rule of particulate matter, modified husky body be built upon that the present inventor proposes " granule is about Bundle " on the basis of principle, it is the thinking of a kind of brand-new sand " soil ".

Constraint type between common sand is " contact ", and its contact point only exists contact pressure and frictional force, And there is no any node adhesion and combine moment (such as node pulling force and moment), therefore, common sand can only By contact pressure and frictional force balancing gravity and external force, its node can not bear pulling force and moment, otherwise, Husky body just will occur sudden change that granule arranges and unstability.

And after the liquid with caking property and adhesiveness is formed modified husky body with sand mix, its granule node Between restraining forces be " adhesion ", it can either produce opposing granule between separate restraining tensile force, again can Enough producing the restraint moment that opposing granule rotates, meanwhile, it can also produce node pressure and frictional force, therefore, All degree of freedom of granule can be limited by it, but this restriction is again limited, and granule node is producing While raw constraint reaction, it is also possible to extend, rotate and slide, therefore, its constraint type and common sand Fundamental difference, say, that modified husky body both can resist external force, again can the most limited and Stably move.On the other hand, in modified husky body, husky body whole interior be constrained to " adhering to constraint ", this Planting constraint is to be formed after sand mix by the liquid with caking property and adhesiveness, on microscopical structure, this Planting constraint is after one layer of adhesion layer of each sand surface uniform fold, contacts again and formed between granule, Therefore, this constraint has universal property and restorability, say, that equal at any point cantact between granule Can form " adhering to constraint ", and after separation, contact between granule again, this binding feature can be recovered. Therefore, modified husky body has the viscoelastroplasticity character of even macroscopic and isotropic, with the mechanics of wet soil Characteristic is the same.

Once after the moisture evaporation in modified husky body, " adhering to constraint " just will become " consolidation constraint ", the most just That the spatial arrangements between sand will be fixed, husky body can bearing load, there is some strength, performance For the character of porous solid, just as dry soil.Meanwhile, as it was previously stated, after meeting water, " consolidation constraint " Becoming again " adhering to constraint ", husky body is become viscoelastroplasticity body from solid.In modified husky body (when no matter doing Or time wet), there is connection, open space all the time, with the external world, moisture, nutrient and the exchange of air occur.

But, if only the described liquid with caking property and adhesiveness to be sprayed at husky surface, it is only capable of Forming one layer of adhesive film in husky surface, infiltration liquid under adhesive film is extremely limited, and this layer adheres to After film is dry, just become solid film, it is clear that this method itself be not based on " particle confinement " principle and Draw, also with the thinking fundamental difference of sand " soil ".It is sprayed on the adhesion layer (solidification of husky surface It is thin layer afterwards) and infiltration liquid in the thinnest scope under adhesion layer, only define about in husky surface Bundle, this constraint, by by force to weak, does not have the most even isotropic nature, comes in and goes out with the character of soil The biggest；Adhesion layer (thin layer after solidification) resides in sand grains surface, can be by the hole between sand Gap completely encloses, this with have connect, the modified sand body fundamental difference of open space, also with the think of of soil Road fundamental difference；In modified husky body constrain in modified husky body inner homogeneous, equivalence is had an effect, with nature The characteristic of soil is similar to, and sprays layer and only have an effect near surface, does not have the characteristic of natural soils.

Second, fundamental difference in architectural characteristic.

On structure dimension, the modified husky body formed after mix, its physical dimension can regulate as required, Paving thickness is changeable, when structural thickness is big, can plant the plant that plant is tall and big, and structural thickness is little Time, the plant that plant is short and small can be planted；And the thickness spraying layer is only formed near surface, its structure chi Very little being difficult to regulates as desired.

In intensity and wear properties, the modified husky body formed after mix, formation is plate body, has plate Mechanical characteristic, in the case of the strength of materials is relatively little, still possesses higher bearing capacity, reaches to fix the sand Purpose, and, the cracking of plate body or destruction, do not destroy its effect fixed the sand, play with the intensity of soil layer Principle is consistent with stability；Meanwhile, modified husky body viscoelastroplasticity in its thickness range, time the wettest Body, or porous solid time dry, all can either stablize the root system of plant, can adapt to again the growth of root system With development, with soil curing plant and adapt to root system of plant development mechanical characteristic consistent.But, spray shape The skin layer become, has the mechanical characteristic (the biggest with the characteristic difference of plate) of thin film, it is necessary to assure enough Intensity, can be only achieved the purpose fixed the sand, and top layer is once destroyed, and is just difficult to retrain the husky body under top layer, and it is solid Husky effect is just difficult to play；Meanwhile, there is no additional constraint, still between the husky body granule under top layer, surface For naturally husky body, it is impossible to stablize root system of plant, with the characteristic fundamental difference of soil.

On pore characteristic, the even pore distribution of modified husky body, there is connection and the opening contacted with the external world Hole, it is possible to the external world, moisture, nutrient and the exchange of air occur, and spray the skin layer of formation, envelope Close husky body to contact with extraneous.

In water conservation, water storage and evaporation characteristic, first, the modified husky water conservation of body, water storage principle are that water is straight Connect to be stored in the liquid with caking property and adhesiveness and (as it was previously stated, liquid removes solid matter be all Water), it is difficult to evaporate and run off, similar with the water conservation of soil, Water storage characteristics, its water conservation, storage capacity Very strong, and this ability can regulate in a bigger scope, it is possible to adapt to various plant Growth, the enforcement in Chongqing shows, the modified husky body of the high storage capacity obtained by regulation match ratio, Can rice cultivation flourishing, until gathering in the crops full Oryza glutinosa；Secondly, the evaporation characteristic of modified husky body Also similar with soil, after the evaporation of moisture in the grains of sand of surface, internal moisture not directly and extraneous contact, from Top to bottm slow evaporation, keeps a rational evaporation and water storage gradient.But, spray the surface formed thin Layer, the characteristic of its water conservation, water storage and evaporation and modification sand body fundamental difference, just spray and to reside in surface thin Water in Ceng, is only capable of penetrating into the scope that below top layer is the least, it is easy to evaporates and is formed and extraneous closing Solid film, now, thin film itself without storage capacity, its water storage principle is: utilize the free water in husky body Point, the complex process evaporate because temperature is uneven in temperature, condense, being hampered, finally make it rest under thin film Region near side, this water storage principle and soil and the water storage principle fundamental difference of modification sand body, storage Moisture is few, is only capable of the growth adapting to minority plant.

3rd, the plantation of plant is different with growth characteristics.

First, in the plantation characteristic of seed, implementing contrast and show, for modified husky body, seed can be embedded in In modified husky body, or being sown in modified husky surface, the germination characteristic according to seed is different, and various seeds are equal Can germinating growth；And for the method for surface sprinkling adhesion layer, after various seeds are buried or are broadcasted sowing, it is necessary to Spray thin layer and adhere to cover layer, but, owing to the moisture below surface coating is few, the seed being partly embedded into Do not germinate or germination is poor；Simultaneously as can close seed after surface coating solidification, (and moisture is Evaporation), the seed broadcasted sowing is after covering thin layer, and same appearance is not germinateed or the situation of germination difference.Therefore, Modified husky body has the character of soil, germination preferably.

In the plantation characteristic of plant, implementing contrast and show, modified husky body can plant various plant, according to The difference of modified husky body thickness, can plant the herbaceous plant that plant is short and small, it is possible to the grass that plantation plant is tall and big This plant, also can plant shrub, and, local thickness and volume at modified husky body can stablize plant roots In the case of system, also can plant high megaphanerophyte；But, form thin layer adhesion cover layer at spraying liquid after, Especially the evaporation of the moisture in thin layer cover layer and after forming solid thin-film layer, serike is to destroy thin film Layer is cost, therefore, after spraying thin layer cover layer, suitably plants any plant more hardly；And plant and plant Spray adhesion layer after thing again, be not much real value.

In the growth characteristics of plant, the universal well-grown of plant in modified husky body, there is no with general soil Difference, according to the difference of modified husky body thickness, modified husky body can be with the short and small herbaceous plant of growth plant, also Can the tall and big herbaceous plant of growth plant, also can grow shrub and arbor, but, only spray at thin layer and cover In the case of, the universal growing state of plant is poor, and, the sand below thin layer cover layer, it is difficult to firm Herbaceous plant (such as Semen Maydis etc.) that plant is tall and big and trees.

It should be noted that above example is only in order to illustrate technical scheme and unrestricted, although With reference to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that, Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention Objective and scope, it all should be contained in the middle of scope of the presently claimed invention.
