Desertification biological ameliorant and preparing and using method thereof

Abstract

The invention discloses desertification biological ameliorant. The Desertification biological ameliorant is prepared from, by weight, 1000-2000 parts of kieselguhr, 400-800 parts of starch-grafting sodium polyacrylate, 200-600 parts of coal cinder, 600-800 parts of moss, 100-400 parts of bamboo charcoal ash, 300-500 parts of coconut shell, 200-300 parts of tea residue, 150-250 parts of seaweed, 100-200 parts of silkworm excrement, 400-800 parts of animal dung, 300-600 parts of biogas residue and 10-50 parts of microbial inoculum. Kieselguhr, starch-grafting sodium polyacrylate, seaweed and other materials are combined with desertified soil to have the remarkable water retention function and prevent water and soil loss, nutrient components in the soil are retained to the maximum, and the material obtained after microbial inoculum fermentation contains enough beneficial bacteria and can provide an enough nutrient source for the desertified soil to improve soil structure and relieve desertification.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil desertification bio-improvement agent, a preparation method and a use method thereof. 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 so...

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
