Abstract

The invention relates to a microorganism fermentation filtrate, and the application thereof to degradation of pesticide residues in soil. According to the microorganism fermentation filtrate and the application thereof, by treating a silybum marianum shell with cellulase and adding active dry yeast, the microorganism fermentation filtrate which can be used for degrading the pesticide residues in the soil effectively is obtained; and the obtained microorganism fermentation filtrate can be used for not only degrading organophosphorus and pyrethroid pesticides in the soil effectively, but also replacing common NPK compound fertilizer as well as promoting the growth of crops.

Description

technical field [0001] The invention belongs to the field of microorganisms and soil restoration, and in particular relates to a microbial fermentation product and its application in degrading soil pesticide residues. Background technique [0002] The use of pesticides in agricultural production has made an indelible contribution to eliminating pests and diseases, eradicating weeds, and increasing agricultural production. However, due to the use of high-toxicity, high-residue, and refractory pesticides, it has also seriously affected the ecological environment and human health. hazards. According to statistics, more than 4 million tons of pesticides are used in the world every year, and more than 90% of the pesticides are left in the soil, air and water. In recent years, people's awareness of environmental protection has been continuously strengthened. In order to protect the ecological environment and the safety of agricultural products, it is urgent to develop a green and...
