Abstract

The invention discloses a pesticide residue degradation agent which comprises the following raw materials in parts by weight: 20-35 parts of chitosan oligosaccharide, 5-10 parts of 24-epibrassinolide,5-10 parts of Biya enzyme, 5-7 parts of beta-complex detoxifying enzyme, 1-3 parts of carbon enzyme, 10-20 parts of shell powder, 6-10 parts of a mixed bactericide, 2-4 parts of potassium selenite, 30-50 parts of water and 10-20 parts of attapulgite. On the basis of accelerating the metabolism of various pesticides, the pesticide residue degradation agent can realize the absorption and the degradation of residual pesticides, thereby greatly reducing the residual level of the pesticides; and at the same time, the pesticide residue degradation agent is capable of activating soil, inhabiting diseases and improving crop quality.

Description

technical field [0001] The invention relates to the field of pesticide degradation, in particular to a pesticide residue degradation agent and a preparation method thereof. Background technique [0002] The invention and use of pesticides have played an irreplaceable role in ensuring and promoting agricultural production. At the same time, the extensive use of pesticides has caused environmental pollution that cannot be ignored. The problem of pesticide residues in soil and crops has also become a food product. Research hotspots in the security field and issues that consumers are most concerned about. [0003] At present, the methods for degrading pesticide residues mainly include physical methods (including soaking and cleaning, sunlight exposure, peeling, adsorption, storage, radiation, ultrasonic, etc.), chemical methods (including hydrolysis, ozone degradation, hypochlorite degradation, hydrogen peroxide, etc.) degradation, photocatalytic degradation, etc.) and biodegra...
