[0005] my country has a vast land area, with an existing area of ​​deserts and desertified land reaching 1.7431 million square kilometers, accounting for 18.12% of the land area and 7.5% of the world's total desertified area. According to authoritative data, the world's desertified soil is currently expanding at a rate of 50,000 to 70,000 square kilometers per year. More than 1 billion people and more than 40% of the land surface are affected by desertification, which is mainly concentrated in arid and semi-arid areas. Vegetation planting in arid and semi-arid areas is the main means of ecological environmental restoration. However, due to the perennial lack of water resources in arid and semi-arid areas, the survival rate of planted vegetation is low. Therefore, the problem of vegetation planting in arid and semi-arid areas has become an urgent problem that needs to be solved, and it is also an objective problem that has existed for many years.

The purpose of lifting the sapling here is to ensure that the direction of the retained main root is not changed by external force, so that the main root is always directed downward, and the above distance must ensure that the main root contacts the wet water layer in step 2 without changing the direction of the main root; the purpose of step 5 is to guide the downward-directed main root to continue to grow downward through the wet water layer in the tree pit, thereby fully improving the utilization rate of water; avoiding the situation in actual tree planting that the primary roots always stay on the surface and are not resistant to wind and sand or drought due to the influence of surface rainwater, dew, etc.; burying the sapling in the tree pit with soil, filling the tree pit, and the filled tree pit is flush with the bottom surface of the water storage pit;

[0058] Step 4: Pre-treatment of the saplings, including the treatment of leaves and roots. For the treatment of roots, generally retain the main root pointing downward and cut off the secondary roots in other directions.

[0059] Step 5, placing the pretreated sapling into the tree pit, first lifting the sapling, and then adding soil; lifting the sapling means lifting the sapling and keeping a distance from the bottom of the tree pit. The purpose of lifting the sapling here is to ensure that the direction of the retained main root is not changed by external force, so that the main root is always directed downward, and the above distance must ensure that the main root contacts the wet water layer in step 2 without changing the direction of the main root; the purpose of step 5 is to guide the downward-directed main root to continue to grow downward through the wet water layer in the tree pit, thereby fully improving the utilization rate of water; avoiding the situation in actual tree planting that the primary roots always stay on the surface and are not resistant to wind and sand or drought due to the influence of surface rainwater, dew, etc.; burying the sapling in the tree pit with soil, filling the tree pit, and the filled tree pit is flush with the bottom surface of the water storage pit;

[0060] Step 6: Coating a hydrophobic substance around the water storage pit to form a hydrophobic film; the hydrophobic substance is a mixture of one or more of hydrophobic epoxy resin, phenolic resin, polyurethane resin and silicone resin; the hydrophobic film around the water storage pit prevents water loss;

[0061] Step 7: Fill the water storage pit with granular matter; the granular matter is locally made of slag, and the water storage pit is filled with slag. During natural precipitation, the gaps between the granular matter in the water storage pit allow rainwater to quickly penetrate into the roots of the saplings, which has a water-permeable effect; the hydrophobic membrane around the water storage pit prevents water loss; during the evaporation process, since the evaporation direction of water is vertically upward, the staggered distribution of the granular matter can block the evaporation of water, while ensuring the air permeability of the entire sapling root, it blocks the evaporation of water, and the hydration effect is long-lasting and effective.

[0062] Step 8, covering the above the particles with a water collection tray; the water collection tray is a mature product on the market, such as the product disclosed in the patent (application number: 201080045666.9 application date: 2010-09-13), the water collection tray is not limited to the above products, the structure of the water collection tray is mainly a water collection surface covering the above the particles, the upper surface of the water collection surface is convenient for collecting rainwater, snow water, dew, etc., the lower surface of the water collection surface is in contact with the particles, which can further prevent the evaporation of water; a relatively closed plant growth environment space is formed between the water collection tray and the hydrophobic film coated on all sides, and the collected water is microcirculated in the closed space, which maximizes the utilization rate of water and improves the survival rate of seedlings. A water collection tray is not necessary, because during natural precipitation, the gaps between the particles in the water storage pit allow rainwater to quickly penetrate into the roots of the seedlings, which has a water-permeable effect; the hydrophobic membrane around the water storage pit prevents water loss; during the evaporation process, since the evaporation direction of water is vertically upward, and the particles are staggered, they can block the evaporation of water, while ensuring the air permeability of the entire seedling root, it also blocks the evaporation of water. That is to say, a relatively closed plant growth environment space is formed between the particles and the hydrophobic membrane coated around it, which can also be used in some environments that are not extremely arid. The water collected in the puddle undergoes microcirculation in this relatively closed space, which maximizes the utilization rate of water and improves the survival rate of seedlings.
