Problems solved by technology

However, with the extension of the cultivation period and the long-term cumulative application of fertilizers, the resistance of underground pests is increasing, and the structure of microbial flora related to nutrient cycling, organic matter decomposition and disease resistance is unbalanced, resulting in soil-borne pathogens and underground pests. The increase in the number of pests, the imbalance of soil nutrients, and a series of problems such as aggravation of pests and diseases, reduction of fertility, and changes in physical and chemical properties will eventually lead to a decline in crop yields, seriously hindering the sustainable development of agriculture and food safety. There is an urgent need for environmentally friendly, economical and effective. Bio-organic fertilizers suitable for crops can reduce the incidence of crop diseases and insect pests on the basis of effectively ensuring high-quality product supply

Abstract

The invention relates to an insect-killing and disease-preventing compound microbial agent and a biological fertilizer containing the same. The insect-killing and disease-preventing compound microbial agent and an organic fertilizer are mixed according to the mass ratio of 1: (1000-1100) to obtain the insect-killing and disease-preventing compound microbial agent. The insect-killing and disease-preventing compound microbial agent is obtained by mixing and adsorbing fermentation liquor of microorganisms and turf according to the mass ratio of 1: 3. The fermentation liquor of the microorganisms comprises bacillus velezensis ZLP-101 fermentation liquor and additional bacteria fermentation liquor in a mass ratio of (50-60): (46-42); the additional bacteria comprise more than three of silicate bacteria K5, bacillus amyloliquefaciens D1, bacillus subtillis BSD-2, bacillus phosphate solubilizing P-6, brevibacillus brevis CH2-22 and bacillus licheniformis BL-9. The composition is harmless to human and livestock, is environment-friendly, and can be widely applied to prevention and control of crop diseases and insect pests and yield increase.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an insecticidal and disease-preventing compound microbial inoculant and a biological fertilizer containing the inoculum. Background technique [0002] To a certain extent, chemical fertilizers and chemical pesticides provide nutrients for crops, reduce the incidence of underground pests, and indirectly increase crop yields. However, with the extension of cultivation years and the long-term cumulative application of fertilizers, the resistance of underground pests is increasing, and the microbial flora structure related to nutrient cycling, organic matter decomposition and disease resistance is unbalanced, resulting in soil-borne pathogens and underground pests. The number of pests increases, soil nutrients are unbalanced, a series of problems such as aggravation of pests and diseases, reduction of fertility, and changes in physical and chemical properties occur, which ultimat...
