Preparing method for degradation agent for biological pesticide residue

Abstract

The invention relates to a preparing method for a degradation agent for biological pesticide residue and belongs to the technical field of preparation of the degradation agents. The method comprises: firstly cultivating aegilops tauschii by using self-made cultivating soil, spraying pesticide and irradiating with X rays in a cultivating process, collecting aegilops tauschii straws on the surface of the cultivating soil, mixing the collected straws with water and then juicing, collecting a juiced solution and juiced residue, pouring the juiced solution into the cultivating soil containing aegilops tauschii roots for fermentation, mixing a fermented product with a glucose solution to obtain a fermentation mixture and filtering the fermentation mixture, collecting supernatant, carbonizing the juiced residue and then soaking a carrier in the glucose solution, and mixing the carrier taken out of the glucose solution with substances such as the supernatant and sodium alginate. The degradation agent for biological pesticide residue prepared through the preparing method provided by the invention is suitable for crops such as wheat, rice, soybean, corn, Chinese cabbage and leek, and is effective for pesticides such as fenpropathrin, dimehypo, carbofuran, carbofuran, dicofol, triazolone and methamidophos and is fast in degradation speed, and can be totally degraded in 9-10 days.

Description

technical field [0001] The invention relates to a preparation method of a biopesticide residue degradation agent, belonging to the technical field of degradation agent preparation. Background technique [0002] After some organochlorine pesticide residues pollute the soil, they will remain in the soil for decades. Once the pesticide residues pollute the groundwater, it is difficult to be degraded. The pesticide residues will form a pollution chain in agricultural production. Once animals eat pesticide residues Food and water sources will be enriched in the body by more than 40 times; human beings eat contaminated meat, grains, vegetables and other foods containing pesticide residues, pesticide residues will accumulate in the human body for more than 70 years, and even endanger the next generation through female pregnancy and breastfeeding. There are two ways for pesticide residues to enter the human body: one is the pesticide residues on the crops, causing them to be directl...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the problem that the pesticide-degrading bacteria directly screened from the environment by the traditional bio-pesticide residue degradation agent have a slow degradation rate, and even cannot survive in the environment for a long time, which affects the degradation effect. Cultivate the stalks of the stalks on the culture soil, and spray pesticides and irradiate with X-rays during the cultivation process. After the cultivation is over, collect the stalks of the stalks on the surface of the cultivation soil, mix them with water and squeeze the juice, collect the squeezed juice and squeeze it. Juice residue, pour the squeezed juice into the culture soil containing the root of barley barley for fermentation, mix and filter the fermented product with glucose solution, collect the upper layer, then carbonize the juice residue, soak it in the glucose solution, and take it out Then mix with supernatant, sodium alginate and other substances
