Problems solved by technology

At present, the soil desertification in our country is becoming more and more serious. If it is not improved in time, it will lead to rapid deterioration of the environment. However, the main means to improve desertification is to plant trees and grass. However, it is difficult to grow trees and grass due to soil desertification. Desertification, the first thing to do is to improve the soil

Abstract

The invention discloses a modifying method for sandy soil. The modifying method for the sandy soil comprises the following steps: step (1), turning the sandy soil; step (2) laying a straw layer in a soil pit; and uniformly spreading a microbial agent on the straw layer, wherein the microbial agent comprises one or more of bacillus subtilis, lactobacillus and saccharomycetes; step (3) laying a fermenting layer on the microbial agent, wherein the fermenting layer comprises bean dregs, vinasse and water which are mixed; step (4) laying a tree leaf layer on the fermenting layer; and step (5) fermenting tree leaves and green grass in a fermenting tank for 20 days to obtain a fermented product, wherein fermenting culture is bacillus subtilis; cutting straws into straw particles, blending the straw particles in the turned soil, blending the fermented product in the straw particles, and covering the tree leaf layer with the soil blended with the straw particles. By the modifying method, a soilenvironment is improved, a soil structure is modified, and finally, a soil desertification condition is improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for transforming sandy soil. Background technique [0002] Soil desertification generally refers to the process of turning good soil or usable land into sandy soil or land or even desert. The main processes of soil desertification are wind erosion and wind accumulation. In the surrounding areas of the desert, due to vegetation destruction or grassland overgrazing or reclamation into farmland, the soil becomes dry due to dehydration, soil particles are scattered, eroded by wind, and the content of fine particles decreases. After the wind has passed or weakened, the wind-blown sand particles gradually accumulate on the soil surface to make the soil sandy. Therefore, soil desertification includes the process of wind erosion of grassland soil and the process of wind-sand accumulation in remote areas. At present, the soil desertification in our country is becoming more and more ...
