Method for preparing biopesticide for organic spinach cultivation

Abstract

The invention discloses a method for preparing biopesticide for organic spinach cultivation. The method comprises the following steps: A, extracting a leaching solution of traditional Chinese medicine compositions including the rhizome of Chinese monkshood, the rhizome of Chinese goldthread, pepper, monkshood, lycoris radiate, dandelion, purslane, cocklebur fruit, cordate houttuynia and andrographis paniculata: after washing, smashing into 150-200 meshes of powder; adding water to soaking for 3 hours, and then stewing; after repeatedly stewing for 3-5 times, filtering out medicine residues to obtain soup, and ultraviolet-sterilizing to obtain the leaching solution for standby application; B, adding bdellovibrio powder, phage powder, green muscardine fungus powder and hirsutella thompsonii powder into an emulsifier, a penetrant and water to be mixed into a solution for standby application; C, adding oil of turpentine and mineral oil into ethyl alcohol, and fully dissolving for standby application; D, adding a synergist into the leaching solution obtained in the step A and then uniformly stirring, and mixing with the solution obtained in the step B and the solution obtained in the step C; after becoming effective, adding a growth regulator and a stabilizer; after mixing, diluting into a solution being 100 times of volume to obtain the biopesticide for organic spinach cultivation. The no-residual fruit and vegetable green pesticide has high efficiency, pertinence, environmental friendliness, no secondary toxicity, no residue, no pollution and no public harm and keeps ecological balance.

Description

[0001] Technical field: [0002] The invention relates to a preparation method of biological pesticides for organic spinach planting. [0003] Background technique: [0004] Currently, the well-known high yields of agriculture necessitate the spraying of large quantities of chemical pesticides to the crops. These harmful pesticides have caused serious excessive pesticide residues in food and the natural environment, which damage people's bodies and affect human health. At present, people have realized the harmfulness of its chemical pesticides, which have changed the soil and made the soil alkalized; polluted the environment. As we all know, pesticides are an important guarantee for ensuring agricultural harvests, but chemical pesticides pollute the environment and destroy ecological balance. The by-products contain high toxicity and high residues, which pose a direct threat to human life and are also a global public hazard. [0005] Invention content: [0006] The tec...
