Embodiment 1
[0020] A low-cost sandy soil improvement method, comprising the following steps:
[0021] S1, granulation, mixing some hydrophobic fibers and hardening agent to form hydrophobic aggregates; the hydrophobic fibers are in the form of long strips with a length of 6cm, and the hydrophobic fibers are woven from polyester and acrylic fibers, and the mass fraction of polyester is 50 , the mass number of acrylic fibers is 50; the hardening agent consists of 7.5 parts of hydrated silicate, 0.8 part of alumina, 1.2 parts of quartz powder, 0.5 part of mica powder and 1 part of water. Solid water-soluble fertilizer and solid water-soluble fertilizer are added in the hardening agent The quality of the solid water-soluble fertilizer is 18% of the mass of the compaction agent, and the solid water-soluble fertilizer is composed of 38.6% of urea, 16.4% of potassium nitrate, 15.6% of ammonium phosphate, 16.3% of dipotassium hydrogen phosphate, 1.7% of boric acid, 1.7% of Magnesium sulfate, 2.1%...

Abstract
The invention belongs to the technical field of desert control, and specifically discloses a low-cost sandy soil transformation method, including the following steps: S1, granulating, mixing and kneading a number of hydrophobic fibers into a group of hydrophobic aggregates, and the hydrophobic fibers are in the form of filaments or strips Or long strips, hydrophobic aggregates are added with compaction agent; S2, laying, spread the hydrophobic aggregates evenly on the surface of the desert; S3, sprinkle water, sprinkle water on the desert, water is poured on the hydrophobic aggregates, and the hydrophobic fibers are stretched after soaking Open, the compaction agent melts in the water and mixes with the hydrophobic fiber; S4, evaporative compaction, waits for the compaction agent and the water on the upper surface of the hydrophobic fiber to evaporate, and after the water evaporates, the hydrophobic fiberboard forms a fiber network; S5, recycling, when the hydrophobic fiber needs to be recycled , sprinkle water on the hydrophobic fiber, the hardening agent is softened, and then stir the hydrophobic fiber, and the hydrophobic fiber is stirred into a ball and recycled. The purpose of the present invention is to provide a low-cost sandy soil transformation method to solve the problem of desertification.
Description
technical field [0001] The invention belongs to the technical field of desert control, and specifically discloses a low-cost sandy soil transformation method. Background technique [0002] Deserts mainly refer to barren areas where the ground is completely covered by sand, with very few plants, little rain, and dry air. The phenomenon of desertification is a natural phenomenon caused by climate change caused by the movement of the earth's dry belt. However, most of the causes of desertification in the world today are attributed to man-made reasons; the rapid population growth, the land where they live are over-cultivated and livestock grazing, resulting in thirsty land that is not suitable for farming. Desertification is a major threat to world agricultural development. It degrades the reproductive capacity of the land, reduces the production capacity of agriculture and animal husbandry, reduces the yield of crops, and reduces the area of arable land and pasture. At pre...
