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 landfill type desertified soil improving method which comprises the following steps: (1) turning over desertified soil; (2) laying a straw layer inside soil pits, and uniformly spraying a microbial agent to the straw layer; (3) laying a fermentation layer on the microbial agent, wherein the fermentation layer is firstly heated to 40 DEG C in a heating device before laying, and is laid before the temperature is reduced to a normal temperature; (4) laying a tree leaf layer on the fermentation layer, and mixing the tree leaf layer with coal ash and kieselguhr; and (5) fermenting tree leaves and grass in a fermentation pond for 20 days, inoculating with a fermentation bacterium, namely bacillus subtilis, so as to obtain a fermentation product, mixing turned soil withstraw granules, further mixing with the fermentation product, and covering the tree leaf layer with the soil mixed with the straw granules. By adopting the method, soil environments can be improved, soil structures can be improved, and soil desertification can be finally alleviated.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a landfill-type sandy soil improvement method. 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 ...
