Embodiment Construction
[0013] The specific implementation of the present invention will be described in conjunction with the examples.
[0014] Application method: Add 20kg of montmorillonite powder, 1kg of polyacrylamide and natural wind-blown sand to 1 ton of soil, mix evenly, and evenly apply it to the place 20cm below the soil plow layer. The surface sand can be peeled off by machinery, and then the mixed sand material is spread, and then the sand Recover to form a 20cm plow layer; add 2 tons / mu of organic fertilizer to the plow layer soil, and control the soil water content at 70%-80% of the field water holding capacity by controlling the amount of irrigation. The improved soil is suitable for planting corn, wheat, Grass and other crops. Anionic polyacrylamide has a molecular weight of 4-6 million and a degree of hydrolysis of 10%-30%. Montmorillonite powder is ultra-fine 400 mesh.
