Description

Water-saving tree planting method by storage method in arid gobi desert, desert and area with annual accumulated snow

Technical Field

The invention relates to the field of greening of Gobi deserts and deserts, in particular to a water-saving tree planting method for arid Gobi deserts, deserts and regions with annual accumulated snow.

Background

From new China to today, the state is wind-proof and sand-proof in arid areas, and a great amount of manpower, material resources and financial resources are invested each year for increasing the rainfall. With the development and progress of society, in order to improve ecological benefit, social benefit and economic benefit, prevent wind and sand, reform drought, green environment, and purify air. Therefore, the important problem of research of the inventor is how to put the place where the gobi sand is not petrochemical and the desert of Maping river and the place where the snow is available in the year in arid areas in the northwest of China to one step and completely solve the scientific water-saving tree planting and forestation work.

The method is characterized in that a plurality of barren mountains and barren lands in China almost become forests, but the forests are not easy in northwest arid areas in China, and even though various methods of dropping and dripping are adopted every year for planting trees and afforesting, the survival rate is low, the practicability is poor, even if drip irrigation is used, a large area of places with a large area have hidden dangers and unmeasured factors, and once power failure and water shortage occur, the method can be abandoned. In summer, the evaporation capacity of water is large, more water drops are not used in turn, and the water drops are less, so that 6 surfaces of the tree pit evaporate quickly, the life can be maintained, and the deep-rooted luxuriant cannot be mentioned at all. The root of the tree grows into a round lump, which is the main reason for the root to grow into the old tree, because the drip irrigation method does not provide the condition and the opportunity for the tree to thrive into the ginseng big tree, and the extension length of the periphery of the root of the tree is not enough. However, the drip irrigation method is difficult to grow into the ginseng big trees in the field.

In addition, in northwest areas of China, a lot of rural street farmhouses are bald and have no trees, hundreds of national roads have no more than ten trees for decades, and the gobi deserts which are too littleer to be observed in a vast area are rather free of trees because a complete technical scheme, water-saving tree planting conditions and a method are not researched.

In the prior art, in order to keep the survival rate of trees planted in arid regions, drip irrigation technology is adopted to provide water, and plastic cloth is laid in tree pits in semiarid regions to keep water and a funnel is adopted to collect rainwater.

The inventor finds that: for the drip irrigation technology, although the dripped water saves water compared with the spray irrigation, the water resource waste still exists due to the conditions of bottom water leakage, peripheral water seepage and large upper evaporation capacity existing in the gobi and the desert; the water for tree planting by drip irrigation has no 'storage capacity', only evaporation capacity, two extremes, no humidity, dryness, only one time, no time, and no influence. The drip irrigation tree hole has small water bearing area, so that the purpose of long root and luxuriant leaves can not be achieved, the survival rate of tree planting is low, and the old trees are more. And the drip irrigation tree planting is provided with a water supply pipe, branch pipe capillaries and more pipe fittings in a pulling way in the field, so the manufacturing cost is high.

For the mode of paving plastic cloth in the tree pits and collecting rainwater by adopting the funnel, as the mode of the tree pits is adopted, although a single pit is not large, under the condition of large-scale afforestation, the workload of digging and planting the trees one by one is large, and the scale of the afforestation is limited; and because the tree pit is smaller in the digging and tree planting mode, the bottom is conical, and the plastic cloth is arranged around the tree pit, the tree root cannot stretch to the periphery and is limited in the tree pit, and the tree is easily blown down by wind. Because the tree pit is smaller, no safety factor exists, when the drought is serious, no reserve water exists, once the problem of serious drought occurs, if the tree planting is less, water can be selected for watering the tree, and the tree planting is more.

The inventor also found that in arid northwest China, there are many places where snow is accumulated in winter, but it is not utilized. The accumulated snow in winter seeps away in the gravel after melting and evaporates in the air, so that trees do not exist in the Gobi beach with baldness, courtyards in villages in cities and towns and beside streets, and natural resources are wasted.

Therefore, the existing afforestation technology in arid gobi desert and desert needs to be changed, which has the problems of low water-saving degree, high cost, low survival rate of tree planting and incapability of afforesting in gobi desert and desert on a large scale, and the problems in the water-saving afforestation work can be completely and thoroughly solved.

Disclosure of Invention

The invention aims to provide a method for planting trees in arid Gobi desert, desert and regions with annual accumulated snow, which solves the problems of low water saving degree, high manufacturing cost and low survival rate of tree planting in the prior art.

The method for planting trees in arid Gobi desert, desert and area with annual accumulated snow comprises the following steps:

the method comprises the following steps: planning the trend of the storage tank to be excavated, and positioning and paying off the gradient and the fall of the storage tank;

step two: plastic cloth is laid in the dug storage tank to prevent the storage tank from leaking water and seeping water, the bottom of the storage tank is 2 meters wide, the wall of the tank is 1 meter deep, and the plastic cloth with the length of 1 meter at each of the two sides of the upper opening is rolled and buried in the edge of the upper opening by soil;

step three: backfilling soil fertilizers into the storage tank, filling the loosened soil to a position higher than the ground, compacting the filled soil close to the left and right side wall parts of the storage tank to a certain degree, and scraping the backfilled soil surface of the whole storage tank;

step four: after the plastic cloth is flattened, the plastic cloth is folded and covered, the outer openings at the two sides close to the wall are covered with a layer of sunscreen soil, the plastic cloth at the tree pit position needs to be left with an air evaporation surface, and the joint of the middle plastic cloth on the storage tank is covered with a straw curtain, so that the storage tank is sealed.

Step five: and irrigating or pouring after the storage tank is refilled or removing snow in the storage tank before the snow is dissolved in spring (in regions with annual accumulated snow).

Step six: when tree planting is carried out in the storage tank; when the tree is planted in time, the tree can sink to the required depth by directly pressing the tree pit without digging and watering, and the upper opening of the tree pit is covered with spade sealing soil.

Furthermore, under the condition that the plastic cloth is afraid of being pricked, in the first step to the third step, a steel plate can be used as a template to be close to the wall of the storage tank, 3 steel pipes are inserted into the reserved space of the outer opening, and the steel pipes and the template are provided with eyelets which support the template; two anchor ropes are fixed on the upper edge of the template through the eyelet, and the peg is inserted at the outer side of the template; to prevent the template from moving. And scraping the bottom surface of the groove flat, paving waterproof layer plastic cloth, backfilling soil suitable for planting, backfilling the soil, backfilling dry sand soil at the outer opening of the template to serve as a protective layer of the plastic cloth, vibrating a lower steel die when the dry sand soil is backfilled by one half of the outer opening, compacting the soil at the outer opening to prevent later slump, and pulling out the steel die and continuously extending the steel tube after the outer opening is filled.

Further, under the condition that quicksand and collapse exist in the desert, preparing enough steel plates as templates in the first to third steps, inserting the templates along a groove line before an excavator excavates, pressing a steel bar pipe downwards by an excavator bucket to enable the templates to sink to 1.2 m, wherein the depth of each groove is 1 m, the steel pipes are used as reinforcing bars for the templates, inserting grooves are formed in two ends of each template 5, an eye is drilled at the upper opening of each steel pipe and used as a hook eye of an anchor rope, an anchor peg is inserted into the ground to be 1 m deep to support the templates through sand, the templates are prevented from moving inwards to cause collapse, and the templates are pulled out after soil filling is completed.

Furthermore, in the fifth step, the water content in the soil of the storage tank is between 70% and 90%, and the tree needs to be dug and watered when being planted.

Furthermore, in the fifth step,

under the condition that the annual accumulated snow is 110 kilograms per square meter, the annual accumulated snow in the row spacing is separated from the middle and pushed into the storage tanks on two sides respectively, the weight of the required snow in each meter of the storage tanks is 660 kilograms, and the planting row number in the first year is not limited.

Under the condition that the annual snow accumulation amount per square meter is 73.3 kilograms, the storage tank needs to distribute one row of snow and a half, the row spacing is 6 meters plus 3 meters, the width of the annual snow is equal to 9 meters, and only four rows of trees can be planted in the same plot in the first year; the weight of snow required by each meter of the storage tank is as follows: the annual snow accumulation is 73.3 kilograms per square meter and is equal to 660 kilograms by multiplying 9 square meters;

under the condition that the annual snow accumulation amount is 55 kilograms per square meter, each storage tank needs annual snow accumulation with the width of 12 meters, two rows of snow are combined into one storage tank to accumulate snow, and the weight of the snow required by each meter of the storage tank is as follows: the annual snow accumulation amount is equal to 660 kilograms by multiplying 55 kilograms per square meter by 12 square meters, and only three rows can be planted in the first year;

under the condition that the annual snow accumulation amount per square meter is 36.2 kilograms, a third snow removal method can be completely adopted for snow accumulation in the first year, 36.2 kilograms is multiplied by 12 square meters to be equal to 434 kilograms of water, the soil moisture content reaches 70%, when the trees are planted, pits need to be dug, water is pulled to water the trees, after the water is poured, grass curtains cover immediately, and more than 70% of water is completely enough for the annual evaporation amount.

In the places with accumulated snow of more than 40 kilograms per square meter in the year, snow removal and management are not needed in the future every year, and the snow removal amount is equal to 80 kilograms by multiplying 40 kilograms by 2 square meters of the tree groove;

the water content in the soil of the storage tank is between 70% and 90%, and the pit is dug and watered when the trees are planted;

snow removal is required to be carried out in the storage tank in spring every year in places where snow accumulated per square meter is 40 kg to 14 kg every year.

Furthermore, after the trees are planted in the desert area, 2-3 shrubs such as blackcurrants and medlar can be inserted between two tree holes, so that the sand prevention and shade shading effects are achieved, and the evaporation capacity is reduced.

Further, under the condition that the gradient of the storage tank is greater than 0.5%, the storage tank in the step one is provided with waist grids, and the water leakage-proof plastic cloth with the waist partitions is not cut off and continues to be constructed towards the tree groove.

The invention has the advantages of

1 'storage method' water-saving afforestation, the name is comprehensive and clear, and the method is simple and easy to understand.

2. The operation is simple and clear at a glance.

3. The management is simple because it is complete and complete, and is in place in one step. Creates the optimal condition for the growth of trees, and ensures that the soil is kept scientific and reasonable forever, thereby obtaining the unique stable soil moisture content. Only irrigation is carried out in the area without snow, dry and early in the year, desert irrigation is carried out, snow removal is carried out once a year when snow is accumulated below 40 kilograms and above 14 kilograms in each square meter year, and snow water is infiltrated and irrigated once. Like a man worried for a year, the man is asked to walk well one year, and the man is simply sent to a large bowl of cold water to drink the full one year without worry, thirst and hunger.

4. In the northwest arid areas of China, the thickness of the accumulated snow is about 0.4 meter in spring, the lowest 40 kilograms of accumulated snow weight per square meter is generally about 100 kilograms, and water sources and management are never considered by using a storage method for afforestation.

5. The accumulated snow in the year has less than 40 kilograms and more than 14 kilograms, and can meet the requirements of tree planting and afforestation in various towns and village streets and roadside roads of farmers and bald farmers houses, and the evaporation capacity of one year can be met by keeping the spirit to clean the snow into a storage tank every time the snow falls.

6. After one year in the gobi desert, the weight of the accumulated snow per square meter reaches more than 40 kilograms, and water is never poured, so that manpower, material, financial resources and water sources are saved. Snow can be removed once a year by less than 40 kg to more than 14 kg.

7. The 'storage method' used in the dry and early area can save more than 90% of water source each year. The drip irrigation method for planting trees has the advantages that water leakage and water seepage are caused, water is evaporated on six surfaces, and the water consumption is more than 90% of that of the storage method. If only the plastic film is used as the waterproof layer on the periphery of the bottom surface, the evaporation capacity of the single upper opening ground is 4-7 times higher than that of the upper opening water of the storage method. Equal to most of the water wasted, in one aspect, the evaporation capacity of the water on the surface of the drip irrigation pit is 4-7 times greater than that on the surface of the pit of the storage tank of the storage method.

8. Compared with the traditional drip irrigation method, the method further reduces the water evaporation and saves water.

9. The water and fertilizer contents in the storage tank are stable, thereby being beneficial to the survival and growth of the saplings and solving the problems of small water-bearing area of the drip irrigation plant pit, low survival rate of the planted trees and more old trees.

10. In some areas with the condition of annual accumulated snow, annual accumulated snow is utilized to provide moisture for filling soil in the storage tank, the water consumption of trees can be guaranteed only by removing snow once every year, and labor cost is greatly saved. The drip irrigation watering frequency is twenty times higher than that of a storage method for one year, and the storage method is used once a year, water is supplied for 1-3 hours, and the snow is accumulated in places without management or weeding for one time in several years.

11. In part of areas with the condition of annual snow accumulation, the annual snow accumulation is larger than the annual evaporation capacity of the storage tank, water is supplemented only for removing snow once during tree planting, watering is not needed after tree planting is finished, watering setting is not needed, management is not needed, and equipment cost and labor cost are greatly saved.

12. The snow removing method of the invention compares the evaporation capacity of the storage tank with the annual snow accumulation capacity, fully considers the surplus of water needed by the storage tank, ensures the water consumption after the tree planting is finished, and has high safety coefficient.

13. Compared with other water-saving afforestation methods, the water-saving afforestation method of the storage method is used in many areas in northwest of China and in areas with large-area accumulated snow in half autonomous region, the storage method does not use water in some places, namely well water, river water and tap water, and the storage method does not need to find out trouble.

The inventor has been advocating science, theory and practice for many years, and the storage method is one-step, and a set of complete technical scheme completely and thoroughly changes the general way of the areas where trees are to be planted under different conditions and environments. For years, the inventor loads a plurality of pieces in the own nursery, tests are successful, and only water is poured once a year. And the survival rate of the drought mountain slope sunny surface gobi desert in two times is ninety nine percent, and the water source is not considered. The water content of the soil is controlled to be about 75 percent. The growth speed is higher than that of other plants because of the stable soil moisture content of the storage method and the constant temperature and humidity.

Example 4

In the arid regions in northwest of China, a large part of regions are not changed in winter after snowfall in winter, snow is changed after the snow is accumulated in spring, and the accumulated snow in the year can be stored and utilized on the basis of the

embodiment

1 or 3 to serve as water for tree planting in the step five and supply of the water after the trees are loaded.

The water required from dry soil to saturation is 310 kg/cubic meter, and through calculation and practical verification, 660 kg of water is required from dry soil to a clear water storage tank per meter length in the

embodiment

1 or 3 of the invention.

The tree planting row spacing is 6 meters, in the first case, under the condition that the annual snow accumulation amount is 110 kilograms per square meter, the annual snow in the row spacing is separated from the middle and respectively pushed into storage tanks at two sides, and the weight of snow on each square meter on each storage tank is 110 kilograms per 6 square meters, which is 660 kilograms. In this case, the number of planted rows in the first year is not limited, as shown in fig. 10.

In the second case, under the condition that the annual snow accumulation amount is 73.3 kg/square meter, the storage tank needs to distribute the annual snow with a row and a half, the row spacing is 6 meters +3 meters, which is 9 meters wide, and only four rows of trees can be planted in the same plot in the first year. The weight of snow required per meter length on the storage tank was 73.3 kg by 9 cm to 660 kg as shown in figure 11.

In the third case, under the condition that the annual snow accumulation amount is 55 kg/square meter, the annual snow accumulation with the width of 12 meters is needed in each storage tank, two rows of snow are combined into one storage tank, the weight of the snow on each square meter of the storage tank is 55 kg/12 square meter which is 660 kg, and only three rows can be planted in the first year, as shown in fig. 12.

In the fourth situation, under the condition that the annual snow accumulation amount per square meter is 36.2 kilograms, the snow can be completely piled by adopting the third snow removing method in the first year, 36.2 kilograms of 12 flat meters is 434 kilograms of water, the moisture content just reaches 70 percent, when the trees are planted, pits need to be dug, water needs to be pulled for watering the trees, after the water is watered, more than 70 percent of water is completely enough for the evaporation amount of one year, and after the storage amount of the first year is finished, external water sources do not need to be considered later.

In the fifth case, to have several rows, it can be seen from fig. 11-12 that only one to two rows can be added to the original tree row in the next year.

In the sixth case, where the accumulated snow is more than 40 kg per square meter in the year, snow removal is not needed and managed every year, and the snow removal amount is 40 kg per 2 square meters of the tree trunk, namely 80 kg.

In the seventh situation, the water content in the soil in the storage tank is between 70% and 90%, and the trees need to be dug and watered when being planted.

In the eighth case, snow removal is required to be performed in the storage tank every spring every year in a place where 40 kg to 14 kg of snow is accumulated per square meter every year.

It should be noted that, in autumn, the trees can be planted in the storage tank filled with soil in the normal manner of digging pits, planting trees and watering trees, and in spring of the next year, snow is removed and water is supplemented in the manner described above, so that the tree planting time in spring of the next year is too late.

It should be noted that the snow removal amount of the storage tank before tree planting is not the same as the storage amount of the dry soil in the storage tank, and the storage amount after tree planting is more than 40 kg of the supplementary annual water evaporation amount required by each cubic meter of soil after tree planting.

In the northwest of China, a lot of places with winter snow are provided, in arid areas, the natural resources which do not cost money for human beings are provided, but are not utilized, all the resources are wasted, so that in Gobi beaches with baldness and rural houses in urban districts, trees are not arranged beside streets, the 'storage method' is provided, the arid areas with snow become forest oases as soon as possible, drip irrigation, spray irrigation and irrigation are not needed, and a large amount of manpower, material resources and financial resources are consumed to well water, river water and tap water, which is unnecessary huge waste.

The weight of the accumulated snow per square meter in the year is more than 40 kilograms, and watering is never needed in the next year after the trees are planted by a storage method. The weight of each square meter of accumulated snow in spring every year is more than 14 kilograms below 40 kilograms, and snow can be removed once a year by a snow remover before the snow is melted in spring. No other water sources are considered. The trees can be changed into forest as soon as possible by using the 'storage method', the ecological environment of arid regions in northwest of China is completely and thoroughly changed, the ecological benefit, social benefit and economic benefit can be greatly changed, the economic forest is formed by using the 'storage method', and the arid regions with land features can be permanently and thoroughly poverty removed and enriched.

1. The 'storage method' is used for planting trees in the places with the annual accumulated snow weight of more than 40 kilograms per square meter (the accumulated snow thickness is more than 20 centimeters in spring) without considering water sources and never watering management.

2. In the places with the accumulated snow weight of less than 40 kg to more than 14 kg per square meter in the year, snow is removed once in the storage tank every spring except that continuous watering is needed for 2 times during tree planting. In the area without accumulated snow, the desert is irrigated with water once a year (snow is removed by a snow remover generally at present).

3, the storage method can keep the soil moisture in the storage tank to be about 70% of the optimum moisture content which is not dry and wet.

The survival rate of tree planting by the storage method is above 98 percent at the lowest, and the water conservation quantity is above 90 percent, wherein the water conservation quantity refers to immeasurable water conservation of local accumulated snow in the year.

The 'storage method' water-saving tree planting fully utilizes the huge resources of the annual accumulated snow and thoroughly solves the huge resource waste.

6. the design of "storage method" planting tree row spacing 6 meters is favorable to solving the utilization ratio and the performance of technique of "holding vessel" and is favorable to the place that the snow of year possesses, and snow removing area needs the design in spring every year, and the foot spacing is designed according to the variety of tree, the size of arbor and bush and the requirement of people.

7. Gobi desert gravel, various pebbles and disordered ruins, a storage tank is used for preventing plastic cloth from being punctured, a thin steel plate is required to be attached to the wall of the storage tank, soil suitable for planting trees is backfilled in the storage tank, dry sand soil is backfilled at the outer opening of a template to serve as a protective layer, then the steel plate is pulled out, and the steel plate continues to extend backwards. (the purpose of using dry sand soil as a protective layer is convenient for the flow of the dry sand soil in the gaps of the protective layer during backfilling).

8. In order to prevent quicksand and collapse of the dug storage tank, templates with different sizes are used, and the supporting template is pressed down by the excavator grab bucket, so that the desert sand is loose and is better pressed.

9. The saline-alkali soil is required to be adjusted to the soil of the storage tank, the periphery of the edge of the storage tank is required to be higher than the ground by more than 20 centimeters, and external saline-alkali rainwater and snow water are strictly prevented from entering the storage tank.

10. In rural courtyards in urban districts, snow removal and watering are not required specially for streets and sides, and attention is paid to the snow removal and cleaning of the streets and the sides of the courtyards in the districts every time snow falls.

The idea of the invention is as follows: is economical and reduces unnecessary waste.

The theory of the invention is as follows: the 'storage method' is used for water-saving tree planting and afforestation, has no trouble and no frustration, has a safety coefficient larger than 50 percent of a base number, and has theoretical support and guidance.

The inventor contracts into a nursery base, becomes a scientific research base for more than ten years, repeatedly studies practice and experiments, and obtains a plurality of successful technical experiences and data (see attached table 1).

What is the storage method? As the name implies: in arid areas, the desert of Gobi desert and desert of Maping river and the area where the annual accumulated snow is more than 14 kilograms per square meter, the water-saving tree planting forestation must be the same as the survival of people, food is stored firstly, water is stored in the water-deficient place, and the water is the source of everything, and the water storage method is as follows: snow water which is melted in the year and water irrigated in a gobi desert or a desert are poured into soil which is stored in a storage tank without water leakage and water seepage, a grass curtain is arranged on an upper cover, and evaporation is reduced, so that scientific and reasonable absorption and air evaporation are realized, and the problems of water resource supply and waste are completely and thoroughly solved.

The formula of the "storage method" includes storage capacity, soil, fertilizer, snow water, irrigation water, humidity, temperature, etc. suitable for tree planting. The ratio of the water storage capacity to the air absorption evaporation capacity must be combined theoretically and practically in scientific research technology. The nursery base contracted by the inventor becomes the scientific research base of the inventor for over ten years, and repeated research and test can obtain a plurality of successful technical experiences and data. It should be noted that what is accumulated in spring is snow accumulated in cold regions, and what is accumulated in winter is snow melted in spring warm regions, and the snow is also called the accumulated snow in spring. The thickness of the accumulated snow is heavy every year, only the weight per square meter can be stated, the thickness cannot be stated, and the snow in the temperate region is unreliable and not preferable.

The following are design scenarios, including:

designing the length of the storage tank: the length of all the storage tanks is not limited, the storage tank is longer as much as possible for reducing cost and facilitating construction, but the storage tank is not more than 0.5% of gradient considering the fall of the terrain, and the storage tank is as long as possible but not more than 200 meters in length under the condition that the terrain allows. The slope is more than 0.5 percent, and the waist separation is needed. The tree roots with the relation of the groove length grow, because the roots are long and leafy, the plastic cloth with more than two meters of waterproof layers is additionally arranged on one waist partition, and the plastic cloth with more than two meters of waterproof layers is not as expensive as the plastic cloth used for leveling the soil, so the tree roots are beautiful and beautiful. The length of the tank also relates to the convenience of watering, and the water is stored in the tank just like a granary, is not lost or wasted, and is only stored to be absorbed and evaporated as required. The water leakage-proof plastic with the waist partition is not cut off and is continuously paved forwards, and the reason is that the water leakage-proof plastic is connected with the waist partition of the next tree groove, so that the watering once a year is facilitated.

Design of reservoir width: the width of the storage tank is limited properly, the width of the storage tank cannot be less than two meters for tree species with long service life and high stature, the width is directly related to loose conditions of tree root growth, the width cannot be absolute or extreme only because the sizes of various terrain conditions of tree planting and afforestation are different, and under the condition that the conditions allow, the width of the plastic cloth is 6 meters and the utilization rate are mainly considered, so the bottom of the storage tank is two meters wide. The excavation holding vessel both sides wall must be perpendicular, and firstly the earthwork construction is convenient, secondly leaves the loose condition of pricking the root for the tree cave, and thirdly increases the memory space of water, if dig into the toper, has two big harmful parts, and firstly the root does not have the growth space, and secondly suffers from infinitly, waits that the tree grows up the back, and the pulling force that does not have the root is blown down by strong wind very easily, so must root deeply to consolidate.

Design of reservoir depth: the groove depth is 1 to 1.2 meters, for example, the grooves of blackcurrants such as flowers and fruits, medlar, grape trees and other shrubs can be properly reduced, and when the width and depth are adjusted to be variable, the sufficient amount of stored water, namely the evaporation amount of more than one year, must be considered. The storage tanks have different depths, the occupied areas are the same, and the water absorption and evaporation amounts are the same. The safety factor is greater than the predicted situation after decades. Safety factors refer to the need to take into account adverse climate changes.

The construction technology of the storage method comprises the following steps: wherever the trees are planted on the terrain, the storage tank is laid according to the flatness of the terrain, for the purpose of construction convenience and watering convenience, the independent tank is responsible for the attitude of no less than 6m3, the flatness is reflected by excavating the bottom surface of the storage tank, the plastic cloth with the width of 6m and the bottom layer with the width of 2 m prevent water leakage, the plastic cloth with the depth of 1 m is used for preventing the water leakage of the two side walls of the tank wall, the two side walls are supported after the plastic cloth is laid, the plastic cloth with the width of 1 m on one side of the upper opening is coiled and buried in the edge of the upper opening by soil, soil fertilizer is filled, after the loose soil is filled to be higher than the ground, in order to prevent watering and loose the soil from sinking, the plastic cloth is rolled left by a small four-wheel tractor head once and right once, a tree pit with the thickness of more than 0.4 m is left in the middle to be not rolled, in order to flatten the tree groove, the tractor head is used for the third time to take a proper weight of the scraper, after one-scraping and flattening, the plastic cloth is folded and covered, the plastic cloth without covering soil can be replaced after being weathered for several years, but the air evaporation surface of 0.3 m × 0.3 m is reserved at the tree pit position, the plastic cloth is not covered, and a layer of straw curtain with the width of 1 m is covered at the joint of the middle plastic cloth on the tree groove. The effects of heat preservation at night, soil moisture preservation, wind prevention and the like are achieved. The small four-wheel tractor head can be specially designed according to the special item for planting trees, the tire is widened, the lifting scraper is arranged at the rear part, and the continuous rolling and scraping are successful.

After the storage tank is dug, waterproof plastic cloth is laid, and the length of the water detecting pipe is also reserved to be 1.2 meters, and the diameter of the water detecting pipe is 3 centimeters. After the backfilling is finished, the steel mould is pulled out, the steel mould is continuously extended backwards, the steel mould is inserted, one third of proper clay is mixed with 1 cubic meter of sand in the tree pit for the tree planting in the desert, the purpose is to fix the tree pit soil with the volume of 1 cubic meter, the trees are prevented from being blown down by strong wind in the future due to loose sand soil, and the better fixation of the tree pit soil can be obtained due to the fact that a little clay is mixed. After the soil fertilizer is filled back, the groove surface is leveled and then is folded and paved with plastic cloth, the upper opening is completely sealed and fixed to prevent water from evaporating, and then a sun-proof soil layer with the thickness of 2 cm is covered. Opening the tree cave mouth before winter and in spring, leaving air evaporation surface of 0.2 m × 0.2 m after the tree is loaded and water is poured, spreading 1 m wide straw curtain without covering plastic cloth, spreading in the middle of the groove, and exposing the plastic cloth for wind prevention and sand scraping. The water injection pipe is arranged at the upper opening of the groove, the desert can not be ditched for open water irrigation, the desert can only be irrigated by boiling water gate valves, a reducing tee with a gate valve downwards at the water opening is arranged in the middle of every three trees along the row of each water supply pipe, the water evaporation capacity of one year is supplemented, and water is injected once a year.

A method for digging a storage tank of all complex soil features that a thin steel plate 2 m long, 1 m wide and 2.5 mm thick is stuck to the storage tank, 4 cm in external opening is reserved for inserting 3 steel tubes 1 m long and 4 cm in diameter, and the steel tubes and the template are all provided with holes, after the steel plates are supported, two anchor ropes 2 m long are hung on the template, and the length of each peg is 0.5 m to prevent the template from moving. And scraping the bottom surface of the groove, paving waterproof layer plastic cloth, backfilling soil suitable for tree planting, backfilling dry fine sand soil at the outer opening of the steel die to form a plastic cloth protective layer after backfilling, vibrating the steel die when the dry sand soil is backfilled by one half of the outer opening, compacting the outer opening soil to prevent later slump, and pulling out the steel die and the steel pipe to continue to extend forwards after the outer opening is filled.

The principle of the storage method is as follows:

research and practice for over ten years proves that the storage method is the most effective technical method for scientific afforestation in dry and early regions with snow and in desert regions without snow. It is only convenient and has no trouble and aftermath. The size design of the device is based on the principle and the function of a storage method: the ratio of the storage capacity to the evaporation capacity is designed, the storage capacity and the evaporation capacity are controlled to be less than seventy-three percent, and the soil is regulated to be not wet or dry by professional knowledge, so the method is called scientific afforestation because the evaporation capacity in the early area is four to seven times of the evaporation capacity at the upper opening of the storage tank.

The row spacing of the trees is 6 meters, the groove width is 2 meters, the depth is 1 meter to 1.2 meters, and the depth of shrub grooves such as blackcurrants and medlar is not necessarily small, and the depth can be 0.8 meter. For tree species with tall stature, what can be done by a large tree after the tree grows to a large tree with a diameter of about 1 m in the future, which cannot be seen by the small seedlings of the current day? All the people learn the principles of lever and mechanics, and the tension and the shearing force of the ginseng-sky big tree are both at the root of the tree, so the width and the depth of the storage tank cannot be underestimated.

The core technology of the storage method is as follows: the water content of soil in each storage tank is the same no matter where the soil is, although the soil is in different geographical positions and the evaporation amount is varied, the evaporation amount controlled by the position of each tree pit is scientific, the size of an evaporation surface can be adjusted regularly according to the difference of the evaporation amount, finally the soil moisture content achieves the required purpose, the water storage amount needs to be mastered in the hands of people by ninety-five percent, like a granary, how many people go out and how many people say it is, and the people cannot be appointed by days, which is the largest core technology. This is science, which derives from the normalization of knowledge from practice and experience.

The core of the storage tank water-saving afforestation technology is to consider the climate fluctuation in advance, which is prepared by tangible and intangible technologies. The design and the row spacing of the storage tanks are designed in such a way that the soil moisture content can be preserved and the survival of trees can be ensured under the condition that the snowfall amount is one half to one third of the normal snowfall amount due to the consideration of climate fluctuation. The size and the line spacing of the storage tank are considered to increase the safety factor.

The saplings can be planted only by watering enough water once, if the saplings are carried in time, the saplings can be directly pressed on the tree pits without digging and watering to sink to the required depth, and the upper openings of the tree pits are covered with spade sealing soil, so that manpower, material resources and financial resources are saved.

The drip irrigation tree planting method has the advantages that the hidden dangers of a plurality of uncertain factors exist in a large-area place in the field, once power failure and water shortage exist in hot summer, due to hot weather, time is urgent, no redundant time is allowed to convolute, previous work can be abandoned, and the hidden dangers are also the main reason for old trees. The tree planting by the storage method has no problems, namely, once water supply is more than required, the water supply is always in a failure, and the water supply problem in the next year is solved due to the annual and half periods of the cycle.

The land area is large, the geology is complex, and various dead lands can be changed and adjusted by a storage method, so that the soil suitable for growing trees can be obtained. All positive energy is fully covered, and according to the advantages, the practicability is extremely strong, the great breakthrough of annual snow accumulation is realized by planting trees by using a storage method, ecological benefits, social benefits and economic benefits are created for the nation and people, and the history pioneer is created.
