Insect-resistant fertilizer filler with purple cabbage waste residues as main material and preparation method thereof

Abstract

The invention discloses insect-resistant fertilizer filler with purple cabbage waste residues as the main material and a preparation method thereof. The filler is prepared from, by weight, 15-25 parts of acrylic acid solution, 0.2-0.5 part of N,N-methylene bisacrylamide, 5-8 parts of corn starch, 3-5 parts of mixed entomogenous fungus powder, 10-15 parts of glucose, 15-20 parts of soybean powder, 4-7 parts of beet molasses, 8-12 parts of corn steep liquor, 1-2 parts of glycerin, 10-16 parts of feed yeast, 60-80 parts of attapulgite, 20-30 parts of white carbon black, 45-70 parts of purple cabbage extract waste residues, 15-22 parts of rice bran, 3-6 parts of ammonium molybdate, 30-40 parts of rice straw, 4-6 parts of agar powder and a proper amount of water. Entomogenous fungi are used as a filling substrate of a fertilizer, crop straw serves as a structure framework, strains are subjected to directed enlarging cultivation and then mixed with starch-grafted high-water-absorption resin and a carrier, and the fertilizer filler is prepared.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an insect-resistant fertilizer filling material based on purple cabbage waste residue and a preparation method thereof. Background technique [0002] Entomogenic fungi play an extremely important role in the biological control of pests. There are many types of them, and their metabolic types are complex. From the subphylum Flagellate to the subphylum Deuteromycota, all contain entomogenic fungi, involving a total of about 100 genera and more than 800 species In recent years, due to the prospect of entomopathogenic fungi in integrated pest control and the application of their metabolites has attracted more and more attention, the use of chemical pesticides to prevent and control agricultural diseases and insect pests has greatly destroyed the ecological balance, and the number and types of pests are one after another. The resistance to pesticides has also increased...

Problems solved by technology

[0005] The use of entomogenetic fungi for pest control of agricultural products is the leading advanced pest control technology in the future, which has the characteristics of safety, novelty and creativity. Like ordinary microorganisms, they must be in a good living environment to exert their greatest effectiveness. It is rare to use them in fertilizers. The chemical elements in fertilizers will greatly change the physical and chemical environment of microorganisms and have a great impact on the survival of microorganisms. Therefore, how to improve It is very important to improve the living environment of entomogenic fungi for the number and activity of insect pests
