Problems solved by technology

At present, my country's crop cultivation mainly relies on chemical pesticides to control diseases. From the perspective of biocontrol, the development of pesticide application reduction at home and abroad mainly focuses on the research and development and production of bacterial agents. The related technologies are relatively proficient, but the common problems are poor stability and weak colonization ability. , Incomplete disease control and other issues
At present, stimulating the plant-induced defense in the plant immune system through plant immune inducers has become a hotspot in the research and development of international biological control due to its stable effect and long-lasting broad-spectrum. However, plant immune inducers alone cannot completely prevent and control diseases

Abstract

The invention relates to the technical field of fertilizers, in particular to a biocontrol type composite additive and application thereof in fertilizers. The biocontrol type composite additive is prepared from the following raw materials: a plant immune inducer and a microbial inoculum, wherein the plant immune inducer is prepared from chitosan oligosaccharide and seaweed oligosaccharide, and themicrobial inoculum is formed by mixing streptomyces microflavus liquid, bacillus megatherium liquid, bacillus licheniformis liquid and bacillus subtilis liquid. The biocontrol type composite additiveis prepared by compounding the plant immune inducer and the biocontrol microbial inoculum, the internal and external mechanisms have synergistic interaction, and the biocontrol type composite additive has broad-spectrum, stable and lasting biocontrol effects. The biocontrol type compound additive is efficiently added into fertilizers by adopting a core-shell coating process. The fertilizers provided by the invention can effectively prevent and treat bacteria, fungi, viruses and various physiological and environmental induced diseases and insect pests, the utilization rate of the fertilizersis improved, the application amount of pesticides is reduced, and the quality of agricultural products is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biocontrol compound additive and its application in fertilizers. Background technique [0002] Fertilizers and pesticides play a key role in the sustainable growth of my country's agricultural production. Many problems caused by excessive fertilization and pesticide application seriously threaten my country's agricultural ecological environment and the quality and safety of agricultural products. At present, my country's crop cultivation mainly relies on chemical pesticides to control diseases. The development of pesticide application reduction from the perspective of biocontrol at home and abroad mainly focuses on the research and development and production of bacterial agents. The related technologies are relatively proficient, but the common problems are poor stability and weak colonization ability. , Incomplete disease control and other issues. At present, the plant-ind...
