High-fertility long-acting anti-verticillium-wilt biological bacterial fertilizer and preparation method thereof

Abstract

The invention relates to a high-fertility long-acting anti-verticillium-wilt biological bacterial fertilizer and a preparation method thereof. The biological bacterial fertilizer is formed by mixing bacterial fertilizer carrier grains and bacterium agent particles. Compared with that of a biological bacterial fertilizer which is commonly used in production, the fertilizer efficiency of the biological bacterial fertilizer is higher. By taking chilies, eggplants and tomatoes as fertilization objects and taking no fertilization, fertilization with an inorganic compound fertilizer and fertilization with an organic fertilizer, chicken manure, as contrasts, the biological bacterial fertilizer can be used for obviously promoting biological yields of the three vegetables, and the biomass of the three vegetables applied with the bacterial fertilizer is more than 50% higher than that of vegetables which are not applied with fertilizer, applied with the inorganic compound fertilizer and applied with the organic fertilizer, chicken manure. A test on eggplants inoculated with verticillium wilt shows that the bacterial fertilizer can be used for effectively inhibiting and relieving the diseases. A soil enzyme activity test shows that the enzyme activity of soil treated by the biological bacterial fertilizer is obviously higher than that of soil without fertilization and that of soil applied with the inorganic compound fertilizer or the organic fertilizer, chicken manure; nitrogen transformation, phosphorus transformation and organic matter transformation capabilities of soil can be facilitated well.

Description

technical field [0001] The invention relates to a high-fertility, long-term anti-Verticillium wilt biological bacterial fertilizer and its preparation process, especially a biological bacterial fertilizer with high nitrogen, phosphorus and organic matter transformation capacity, high effective viable bacteria count and anti-Verticillium wilt . Background technique [0002] Our country started the production and research of microbial fertilizers as early as the 1950s, and has made great progress after years of experiments and research, and achieved good results in long-term agricultural production applications. Among the microbial fertilizers in my country, rhizobia fertilizers are the most widely used. Among them, soybeans, peanuts, milk vetch and leguminous forages have a large inoculation area, and the effect of increasing production is obvious. At the same time, other types of bacterial fertilizers have developed rapidly in my country in recent years. In the field of re...

Problems solved by technology

There is a risk of pesticide residues in the use of chemical drugs. If biological fertilizers can be used to improve the environment of soil probiotics and inhibit or kill pathogenic bacteria, it will become an important means of biological control.
