Abstract

The invention discloses a preparation process of a cowpea domestication trichoderma fermented soybean straw-based fertilizer. The preparation process comprises the following steps: (1) preparing a cowpea domestication trichoderma seed solution; (2) obtaining pretreated soybean straw; (3) obtaining a pre-fermentation product; and (4) fermenting by cowpea domestication trichoderma; according to thecowpea domestication trichoderma fermented soybean straw-based fertilizer prepared by the method, the organic matter content and nitrogen, phosphorus and potassium components of soil can be remarkablyincreased, the nutrient components of the soil are greatly increased, and the physical and chemical properties of the soil are improved.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a preparation process of cowpea domesticated Trichoderma fermented soybean straw-based fertilizer. Background technique [0002] In recent years, crop straw has become a new source of pollution in rural areas. Every year during the summer harvest and autumn and winter, a large amount of straw such as wheat and soybeans is always burned in the field, producing a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit of the urban environment. [0003] Therefore, how to better utilize these crop straws and reduce their impact on the environment is a problem that needs to be solved at present. [0004] Soybean straw contains cellulose, hemicellulose, lignin, organic matter, nitrogen, phosphorus, potassium and trace elements, etc., and is rich in nutrients. Fertili...
