Bio-organic fertilizer for killing underground insect pests by using biological agent and preparation method of bio-organic fertilizer

Abstract

The invention discloses a bio-organic fertilizer for killing underground insect pests by using a biological agent and a preparation method of the bio-organic fertilizer. The bio-organic fertilizer is prepared from the following raw materials in parts by weight: 5-15 parts of a beauveria bassiana agent, 10-20 parts of cow dung, 20-30 parts of pig manure, 10-15 parts of chicken manure, 10-15 parts of cassava residues, 5-10 parts of furfural residues and 15-25 parts of sesame-seed cakes. The beauveria bassiana agent comprises the following components in parts by weight: 40-50 parts of a beauveria bassiana spore powder mother drug, 20-30 parts of a beauveria buchneri spore powder mother drug, 20-30 parts of corn flour and 10-20 parts of glucose powder. The preparation method comprises the following steps: (1) preparing a base fertilizer; (2) performing microbial inoculum culture; (3) airing the base fertilizer; and (4) performing microbial agent mixing. The organic fertilizer provided by the invention utilizes a biological agent to kill underground pests, has a long lasting period of pest control, is non-toxic to people, bees, fishes and the like, has no pollution to the environment, has a good disinsection effect and long fertilizer efficiency, and can reduce environmental pollution caused by chemical pesticide disinsection.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a bio-organic fertilizer for killing underground pests by using biological bacteria agents and a preparation method thereof. Background technique [0002] Subterranean pests refer to omnivorous insects that live in the soil and harm the underground parts of plants, seeds, seedlings or main stems near the soil surface during their whole life or at a certain stage of their life. Occurrence types vary from place to place, and generally occur in dry farming areas, especially grubs, dayworms, cutworms, ground maggots, and nematodes are the most serious. After the crops are damaged, the light ones will wilt, the growth will be slow, and the severe ones will wither and die, resulting in lack of seedlings and broken ridges, resulting in reduced production. [0003] The following problems exist in the use of pesticides to eliminate insects: 1. The resistance of insect pests to pesticid...

AI Technical Summary

Problems solved by technology

After the crops are damaged, the light ones will wilt, the growth will be slow, and the heavy ones will wither and die, resulting in lack of seedlings and broken ridges, resulting in reduced production.

[0003] The following problems exist in the use of pesticides to eliminate insects: 1. The resistance of insect pests to pesticides is enhanced, which greatly reduces the control effect; 2. It is difficult for chemical pesticides to move in the soil, resulting in worse and worse control effects; 3. The duration of pest control short
