Problems solved by technology

General microbial inoculants have shortcomings such as too long time to knock down pests and unstable control effect. Therefore, how to improve the efficiency of these biological insecticides and make them have a stable and long-term control rate is the key to this type of inoculum.
Secondly, the development of microbial agents in my country's agricultural applications is relatively slow. Due to weak scientific research, there has been no breakthrough in strain screening, domestication, fermentation technology, and strain compatibility; Accurate application data makes the development of promotion and application lag behind. Many related products on the market do not meet national standards, the effect is not obvious, and it is not conducive to its promotion and popularization.

Abstract

The invention discloses a microbial agent with a disease and pest control function, and belongs to the field of fertilizer series. The microbial agent is prepared from the following raw materials in parts by weight: 40-60 parts of a composite microbial agent, 10-20 parts of chitosan, 10-20 parts of corn steep liquor dry powder, 20-30 parts of modified bentonite, 10-20 parts of potassium fulvate and 0.5-1.5 parts of a synergist. The compound microbial bacterium powder is prepared from bacillus licheniformis, bacillus subtilis, bacillus mucilaginosus and paecilomyces lilacinus according to the mass ratio of 1: 1: 3: 5. All the components have a synergistic effect and a proliferation relationship to form a complex biological flora which is stable in structure and wide in function and has various bacterial microbial communities, and the microbial agent is obvious in insect-resistant and antibacterial effect, simple and easy to implement, low in cost and wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a microbial agent with the function of preventing and controlling diseases and insect pests and a preparation method thereof. Background technique [0002] Chemical pesticides have played an active role and made great contributions in controlling plant diseases, insects, and weed damage, regulating plant growth and development, increasing food production, and meeting human survival needs. For a long time, the problem of pesticide residues and persistence has had a great impact on crops. Especially for vegetables and fruits, it is often necessary to apply various insecticidal and bactericidal pesticides multiple times during the growth period, which directly endangers people's health. [0003] Microorganisms are ubiquitous in nature, from as small as a single cell to as large as the Earth's biosphere. From land to sea, from aquaculture, animal husbandry to agricul...
