Description
Technical field
The present invention relates to soil remediation field, more particularly to a kind of red soil conditioner of wormcast compounding molydbenum fertilizer.
Background technology
According to statistics, the Red Soils in Southern China area gross area reaches 217.96 ten thousand square kilometres, including 15 provinces (area), accounts for complete
The 1/5 of state's land area；Population 4.8 hundred million, accounts for the whole nation 40%；Plough 28,000,000 hectares, account for the 30% of the whole nation.In the whole nation 1/3
The agriculture value of national half, the grain of half and the population for having born nearly half are provided on arable land.But due to for a long time to soil
The irrational utilization of ground resource, for whole distract ecology with environment by heavy damage, soil degradation problem is extremely serious, just wraps
Include the following aspects：
1st, soil acidification is serious, and red soil soil fertility recovery tasks are arduous：
The desiliconization allitization process of red soil is originally a more slow acidization.But due to by acid rain depositions, ammonium nitrogen
Quickening of the use of hypertrophy amount, agricultural planting system, cultivation in farmland management measure and human industryization process etc. influences, and expands
The scope of soil natural acidifying and the speed for accelerating self-souring, so as to produce harmful effect to plant growth and environment.In
State about 200,000,000 hectares of (hm of all kinds of acidified soil areas2), wherein Guangdong Province accounts for 60%.Soil acidification becomes restricts China's agriculture
One of significant obstacle of industry sustainable development.
Research shows：The several heavy Acid Rain Zones in China are all in red earth area, about 2,000,000 hectares of the area of acidified soil, China
Most of tropical and subtropical region and cloud, expensive, river etc. of the main integrated distribution of acid soil on the south the Changjiang river be red, yellow earth
Area.Such as：Nanchang is one of two acid rain centers of south China, and rainwater pH value is 4.5-5.0, and minimum 3.2, acid rain is frequently
Rate is more than 80%.In addition, soil acidification can increase soil aluminium ion, murder by poisoning is produced to crop；It can also cause soil at the same time
Middle K+、Na+、Ca2+、Mg2+And NH4+Deng base cation leaching loss, cause soil depletion, fertility reduces；And for minerals such as nitrogen, phosphorus
The validity of nutrient and having a great influence for content.In addition, soil acidification can suppress the activity of edaphon, reduce organic
The decomposition rate of carbon, has an impact water acidification, all these to illustrate, soil acidification has become restriction China's agricultural to be held
One of significant obstacle of supervention exhibition.
2nd, the content of organic matter declines：
The soil organism is soil fertility and the important indicator of soil quality, and it is that soil nutrients and soil is barren that the content of organic matter, which is reduced,
Change undisputable fact.The content of organic matter in China arable land is generally relatively low, and paddy field soil is mostly in 1%-3%, and dryland soil has
Machine matter content is low compared with paddy field,<1% accounts for 31.2%；The soil organism is ploughed after cultivating 10 years, its content in the case of only use is not supported
31% is reduced, ploughs after cultivating 50 years and reduces 55%.
Orchard content of organic matter survey data shows that the sample number that the content of organic matter declines reaches 66.7%, and soil is organic
The effect of confrontation soil fertility is divided into directly effect and indirectly-acting.Directly act on：Solubility in the soil organism organises
Many components of compound are (such as：Nitrogenous, phosphorous fragment) can directly it be absorbed and used by plants, and the soil organism contains substantial amounts of plant
Thing grows necessary element and trace element, in fact, the soil organism is the storehouse of a great number of elements, there is provided surpasses in organic matter
95% nitrogen and the phosphorus of sulphur and 20%-70% is crossed, the decomposition of the wherein chronic component of organic matter is mineralising nitrogen and other nutrients
Important sources, while sufficient nutriment is provided for edaphon, in addition, the growth discharged during decomposition of soil organic matter promotes
Material such as vitamin, amino acid, plant hormone etc., can also stimulate the growth of microorganism and plant.Indirectly-acting：Soil is organic
Confrontation soil productivity more importantly indirectly-acting, the i.e. influence to soil attribute：Reduce soil density, increase soil water retention
Power, the stability for strengthening soil agreegate.In addition, it plays a decisive role Cation Exchange Capacity in Soils and field capacity.Have
The high soil of machine matter content contributes to soil warming and promotes the activity of edaphon.Usually, with the soil organism
Increase, cation exchange capacity (CEC), buffer capacity, pH value and adsorption by soil effect and soil microbial biomass all increase therewith.Cause
This, it is one of important channel for lifting soil fertility to improve soil organic matter content.
3rd, the soil weight increases：
The soil weight is negatively correlated in conspicuousness for crop growth, saturated aqueous rate.The increase of unit weight causes soil
Adjust water, fertilizer, air and heat ability to decline, and harmful effect is produced to the Ecological and Physiological Effect of root system of plant.Topsoil thickness increase association
Water transfer, fertilizer, air and heat ability can also improve, and general high fertility soil has a deep topsoil, the low fertility of its volume to weight ratio it is low
0.3g/cm3, total void is high by 16%, natural moisture content, field capacity, effect water capacity difference it is high by 4%, 5%, 9%, not only
Influence soil moisture, temperature, oxidation-reduction potential, moreover it is possible to influence below the 20cm soil moistures.
Research shows：Many hardened soil can change the soil weight in short term by revolving, turning over, but crop growth initial stage very
The fast heavy reality become again, unit weight increase, main cause is that the soil organism is generally relatively low, and soil constitution and build are poor；Secondly, it is long
Phase no-tillage with stubble retention or the cultivation of long-time service small machine also gradually cause topsoil to shoal unit weight increase, not only influence soil
Water storage water holding capacity, and influence to prick under crop root；In addition, soil suction can increase with the increase of unit weight, soil holds
Increase the migration and conversion for also seriously affecting nutrient element in the soil water again；Furthermore not only directly affect the porosity of soil, lead to
The penetrability of gas and root system, but also the quantity and activity of Soil Microorganism are changed indirectly.So reduce soil
Earth unit weight, applying organic manure are one of effective ways for reducing the soil weight.
4th, trace element molybdenum lacks serious：
Easily there is scarce molybdenum problem in acid soil, and the vast khoai in south belongs to scarce molybdenum area, though full molybdenum content is high, can give
Property is low, and effective molybdenum content is few.In the soil, molybdenum is mainly with molybdenum acid ion (MOO4 2-) form presence, participate in each life mistake
Journey.The content of Available Molybdenum in Soil is to evaluate the index that soil supplies molybdenum ability, high concentration nitrogen level, low temperature and low pH (<
5.5) utilizability of molybdenum is relatively low in soil.
Molybdenum is one of main ingredient of molybdoflavoprotein enzyme in plant azotobacteria, and the master of plant nitrate reductase
Want one of composition.Molybdenum can excite phosphatase activity, promote the synthesis and conveying of sugar and starch in crop, be conducive to early ripening of the crops.
Its major function is：The processes such as fixed nitrogen, amino acid metabolism, nitrogen conversion in participation plant, and with enhancing plant photosynthesis
Effect, improves plant cold resistance, drought resisting and disease-resistant ability, in addition, molybdenum may additionally facilitate formation and the plant of breeding plant organ
The formation and conversion of interior carbohydrate, its transforming degree are proportionate with the concentration of molybdenum within the specific limits.Molybdenum cofactor is molybdenum enzyme
Constituent, molybdenum have a variety of chemical valences, and molybdenum enzyme take part in a variety of redox reactions in organism.Sent out at present in bacterium
Existing more than 50 kinds of molybdenum enzyme (Leimk ü hler and Iobbi-Nivol2015), the molybdenum enzyme being present in plant has 5 kinds, is nitric acid respectively
Salt reductase (nitrate reductase, NR), xanthine dehydrogenase (xanthine dehydrogenase, XDH), formoxy-
Change enzyme (aldehydeoxidase, AO), sulfite oxidase (sulfiteoxidase, SO) and mitochondria amidoxime reduction egg
(mitochondrial amidoximereducing componen, mARC) in vain.Plant by these molybdenum enzymes participate in nitrogen,
Carbon, purine, hormone and sulphur metabolic process in.
Shown according to soil survey information, 68% is middle-and-low-yielding fields in current farmland, and 64% lacks molybdenum.It is reported that it is grown in
The crops such as the winter wheat on the low Indian yellow umber earth of effective molybdenum content occur seriously lacking molybdenum symptom.Lacking molybdenum symptom has molybdenum enzyme activity
Property reduce, nitrogen hunger reaction, stem and leaf development are obstructed, leaf necrosis, seed development is bad, fruit-setting rate reduces etc..And cause scarce

All results are in terms of the average value in 3 plot
(2) instrument and reagent：
Ultraviolet-uisible spectrophotometer：The general analysis TU-1810 in Beijing；
Assay balance：The double outstanding board centesimal balances in the U.S. and Precisa balances very much；
Sodium molybdate (Na2MoO4·2H2O)：Guangzhou Chemical Reagent Factory produces, AR；
Remaining agents useful for same derives from Guangzhou Chemical Reagent Factory, and glass apparatus derives from northern glass.
Soil pH value：
Some researches show that：Soil acidification can increase soil aluminium ion, and murder by poisoning is produced to crop；K in soil can also be caused+、Na+、Ca2+、Mg2+And NH4+Deng base cation leaching loss, cause soil depletion, fertility reduces；To mineral nutrient elements such as nitrogen, phosphorus
Validity and content have a great influence；Meanwhile soil acidification can suppress the activity of edaphon, the decomposition of organic carbon is reduced
Speed, usual soil pH value is higher, and the decomposition rate of soil organic matter is faster.
It will be seen from figure 1 that the QY-CK soil pH values for not applying conditioner are 4.93, using the QY-T1 soil of conditioner
PH value improves 0.17 than QY-CK, and QY-T3 improves 0.24 than QY-CK.This explanation, which applies conditioner, can effectively improve soil
PH value, and soil pH value increases with the increase of conditioner amount of application.
The main component of conditioner is wormcast, straw mushroom slag, vermiculite and maize straw, during the pH value of these four components is
Property or alkalescence, secondly, wormcast is mainly aggregate structure, and water-stable aggregate content is high, there is a stronger resiliency, and corn
It is in alkalescence after stalk fermentation.Above-mentioned neutral or alkalescence material addition can neutralize cation unnecessary in characteristic of acid red soil, from
And the quantity of red soil cation is reduced, improve soil pH value；Along with this conditioner also contains substantial amounts of organic matter, and organic matter
Usually carry substantial amounts of negative electrical charge, meanwhile, the humus in organic matter has colloid property, can adsorb in red soil substantial amounts of sun from
Son, can also improve red soil pH value from another point of view；In addition, vermiculite has very strong adsorptivity and ion exchange, thus, this tune
Reason agent can effectively adsorb the cation in red soil, reduce the quantity of red soil cation, the change rate of red soil electric charge be buffered, so as to have
Improve red soil pH value in effect ground.
The soil weight：
Figure it is seen that the soil weight of QY-CK is 1.71g/cm3, using the QY-T1 soil weight ratio of conditioner
QY-CK reduces 0.22g/cm3, and QY-T3 reduces 0.39g/cm than QY-CK3.It can be seen from the above that the soil weight is with conditioner
The increase of amount of application and reduce.Meanwhile it is observed that the soil of QY-T3 and QY-T1 substantially compares QY-CK from cutting ring spot sampling
Loosely, in addition, aeration and crumb structure are better than QY-CK.
The main component wormcast, straw mushroom slag, maize straw and vermiculite of this conditioner, are all the bases for having good aeration
Matter, wormcast have good crumb structure in itself, and aeration is good, and straw mushroom slag is after producing straw mushroom as raw material using Chinese medicine slag
Residue, still has the stalk of more Chinese medicine and branch not to rot completely, main component is organic carbon after corn stalk powder fermentation.Institute
With the addition of this conditioner, can increase the type and quantity of organic colloid well, can effectively increase soil aggregation structure
Formed, so as to improve soil self-regulation ability；Further, since organic matter plastid itself is smaller, unit weight is reduced；Furthermore
Because organic matter is rich in fine pore, water imbibition is strong, and water swelling, can keep the prolonged rarefaction of red soil.Therefore, nurse one's health
Agent can be effectively reduced red soil unit weight, increase red soil aeration, so as to improve the structure of red soil.
Soil organic matter content：
The soil organism is soil fertility and the important indicator of soil quality, and effect of the soil organism to soil fertility divides
For directly effect and indirectly-acting.
Directly act on：Soluble organic compounds are nitrogenous in the soil organism and phosphorus fragment can directly absorb profit by plant
With, and the soil organism contains substantial amounts of element and trace element.In fact, the soil organism is the storehouse of a great number of elements, carry
The phosphorus of nitrogen in organic matter more than 95%, sulphur and 20%-70% are supplied.The decomposition of the wherein chronic component of organic matter be mineralising nitrogen and
The important sources of other nutrients, and sufficient nutriment is provided for edaphon.In addition, discharged during decomposition of soil organic matter
Growth promoting substance is (such as：Vitamin, amino acid, plant hormone etc.) growth of microorganism and plant can be stimulated.
Indirectly-acting：The soil organism to soil productivity more importantly indirectly-acting, the i.e. influence to soil attribute,
Reduce the soil weight, increase soil water holding capacity, the stability for strengthening soil agreegate.Certainly, the inert component of the soil organism
It is closely related with the colloid property of agron, and play a decisive role to the cation exchange capacity (CEC) and field capacity of soil.
The high soil of the content of organic matter contributes to the soil moisture to rise and improves the activity of microorganism.Usually, with the soil organism
Increase, cation exchange capacity (CEC), buffer capacity, pH value and adsorption by soil effect and are edaphon all with increase
Growth carbon source and the energy are provided, so as to promote the breeding of microorganism and the activity of soil enzyme.
From figure 3, it can be seen that the soil organism of QY-CK is 34.8g/kg, the soil organism of QY-T1 is carried than QY-CK
It is high by 10.9%, and QY-T3 improves 12.6% than QY-CK, it can be seen that, it can effectively improve the soil organism using conditioner
Content, and soil organic matter content increases with the increase of conditioner amount of application.
In this soil conditioner using organic matter as base stock prepare, therefore can be provided for soil substantial amounts of organic matter from
And the content of soil with organic matter is improved, promote the growth of plant and improve comprehensive quality.
Available Molybdenum Content In Soils：
Soil depends on content, form and the validity of Molybdenum in Soils for molybdenum ability, is also closely related with pH value.Molybdenum in Soils contains
Amount is different because of soil types, and is influenced by soil parent material.Being shown according to soil survey information, the soil that China has 64% lacks molybdenum,
The scarce molybdenum soil of South Red Soil Region is mainly red earth, laterite, red soil etc., and full molybdenum content is higher and effective molybdenum is relatively low.
Effective molybdenum only accounts for seldom ratio of full molybdenum, and the existing forms of molybdenum in the soil can be divided into four kinds, i.e., water-soluble molybdenum (can
Be dissolved in the water), replacement state molybdenum (MoO4 2-Or MoO4-) anionic form adsorbed by clay mineral), organically combine state molybdenum (deposits
In the soil organism), indissoluble state molybdenum (molybdenum fixed by host mineral and iron lead oxides).The molybdenum of these four types exists
It can mutually change, and convert to each other more rapid under certain condition.Water-soluble molybdenum, replacement state molybdenum and part organically combine state
Molybdenum is Available Mo In Soil, and the change of soil pH value influences whether the existence form of molybdenum in soil, and as pH ＞ 4, master is played with MoO4 2-
Based on；During 2.5 ＜ pH ＜ 4, principal mode is HMoO4-、Mo(OH)6；During pH ＜ 2.5, mainly with non-ionic H2MoO4-Go out
It is existing.
From fig. 4, it can be seen that the content of the Available Mo In Soil of QY-CK is 0.087mg/kg, QY-T1 is improved than QY-CK
23.0%, and QY-T3 improves 16.1% than QY-CK.It can be seen from the above that Available Molybdenum in Soil can be significantly improved using conditioner
Content, but decline on the contrary with the increase of conditioner amount of application.
The validity of molybdenum in the soil depends primarily upon the supply of effective molybdenum, influences the factor of effective molybdenum supply very
It is more, mainly have in the degree and soil that molybdenum content in soil, quality, acidity, abundance of organic matter, humidity, pH, effective molybdenum are adsorbed
Interaction between other nutriment and molybdenum etc..Wherein, soil molybdenum content is the basis of effective molybdenum, it is with effective molybdenum in most feelings
There are preferable correlation under condition.Acidity is to influence effective most important factor of molybdenum, and pH value is lower, and Available Molybdenum in Soil content is got over
It is few, work as pH>When 5, soil pH often improves a unit, MoO at this time4 2-Concentration can increase by 100 times.Supplied with effective molybdenum merely
Measure to judge the supply situation of Molybdenum in Soils, it is considered that 0.15mg/kg is the critical value of Molybdenum in Soils supply.According to this principle,
Effective molybdenum is bigger less than soil phosphorus forms, then also bigger using effect, i.e.,：It is more using conditioner, the content of its Molybdenum in Soils
More, effective molybdenum is also bigger, but when the content of organic matter is excessive, organic matter easily adsorbs excessive molybdenum so as to cause organically combine state molybdenum
And the increase of indissoluble state molybdenum, cause the content of effective molybdenum to reduce, the additive amount here it is CS-T3 molybdenums is than CS-T1 high, but soil is effective
Molybdenum on the contrary than it is relatively low the reason for.Certainly, when condition changes in the soil, the molybdenum of both forms can change into water rapidly
Molybdenum and replacement state molybdenum, utilize for plant absorption.Therefore, the administration of this red soil conditioner, can effectively improve Available Mo In Soil
Content.
Plant amount containing molybdenum：
Molybdenum is one of main ingredient of molybdoflavoprotein enzyme in plant azotobacteria, and the master of plant nitrate reductase
Want one of composition.Molybdenum can excite phosphatase activity, promote the synthesis and conveying of sugar and starch in crop, be conducive to early ripening of the crops.
Its major function is：The processes such as fixed nitrogen, amino acid metabolism, nitrogen conversion in participation plant, and with enhancing plant photosynthesis
Effect, improves plant cold resistance, drought resisting and disease-resistant ability, in addition, molybdenum may additionally facilitate formation and the plant of breeding plant organ
The formation and conversion of interior carbohydrate, its transforming degree are proportionate with the concentration of molybdenum within the specific limits.Molybdenum cofactor is molybdenum enzyme
Constituent, molybdenum have a variety of chemical valences, and molybdenum enzyme take part in a variety of redox reactions in organism.Sent out at present in bacterium
Existing more than 50 kinds of molybdenum enzyme (Leimk ü hler and Iobbi-Nivol2015), the molybdenum enzyme being present in plant has 5 kinds, is nitric acid respectively
Salt reductase (nitrate reductase, NR), xanthine dehydrogenase (xanthine dehydrogenase, XDH), formoxy-
Change enzyme (aldehydeoxidase, AO), sulfite oxidase (sulfiteoxidase, SO) and mitochondria amidoxime reduction egg
(mitochondrial amidoximereducing componen, mARC) in vain.Plant by these molybdenum enzymes participate in nitrogen,
Carbon, purine, hormone and sulphur metabolic process in.
From fig. 5, it can be seen that the plant amount containing molybdenum of QY-CK is 0.27mg/kg, the plant amount containing molybdenum of QY-T1 is QY-CK
3.8 times, and QY-T3 is 25 times of QY-CK.As it can be seen that the amount containing molybdenum in plant body can be significantly improved using conditioner, and with tune
The increase of agent amount of application is managed, the content of molybdenum also increases sharply in plant body, this explanation plant absorbs molybdenum element by the external world, and adjusts
Manage in agent containing the higher effective molybdenum of concentration, therefore the molybdenum content in plant body can be significantly improved.
