Abstract

The invention discloses a preparation method of a biogas slurry containing biological pesticide. Urea, liquid polymeric ferric sulfate and a laundry detergent are added to biogas slurry to form a biogas slurry mixed solution, the weight ratio of the urea to the liquid polymeric ferric sulfate to the laundry detergent to the biogas slurry is 1:4:1:(400-500), and the biogas slurry mixed solution is sealed for 3-4 months; perfume, a dispersant and a curing agent are sequentially added to the biogas slurry mixed solution, the mixed solution comprises the added ingredients in percentage by weight as follows: 0.4%-0.8% of the perfume, 0.4%-0.6% of the dispersant agent and 0.4%-0.6% of the curing agent; the dispersant is polyethylene glycol 400; the curing agent is polyacrylamide; the biogas slurry mixed solution is left to stand for 7-10 days after being uniformly stirred, and then the biogas slurry mixed solution is filtered and purified; the biogas slurry mixed solution is filtered by multiple layers of filtering nets sequentially, a filtrate is obtained, and the filtrate is the biogas slurry containing biological pesticide. If the biological pesticide is sprayed to leaves of fruit trees and vegetables for a long time, fruits are large, the yield is increased, little leaf diseases and panama diseases can be controlled, the killing rate of the pesticide for red spiders, yellow spiders, arrowhead scales, suzumusi and the like is higher than 98%, and the biogas slurry containing biological pesticide is non-toxic and harmless to people and livestock and doesn't pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a preparation method of biogas slurry biopesticide. Background technique [0002] Pesticides are chemical synthetic preparations used to prevent, eliminate or control diseases, insects, weeds and other harmful organisms that endanger agriculture and forestry, and to regulate, control and affect the metabolism, growth, development and reproduction of plants and harmful organisms purposefully, or It is a mixture and preparation of natural products and substances produced by applying biotechnology. In agricultural production, pesticides are used to protect and promote the growth of plants and crops. They are insecticides, fungicides, and a class of drugs that kill harmful animals or weeds, or pesticides that control diseases and insect pests and regulate plant growth. [0003] The earliest pesticides used can eliminate pests in large quantities, but they ha...
