Abstract

The invention discloses a liquid compound microbial fertilizer containing polyglutamic acid, and a preparation method and an application thereof, and belongs to the field of compound microbial fertilizers. Bacillus megaterium, bacillus thuringiensis and bacillus amyloliquefaciens are prepared into a bacteria liquid by liquid fermentation, and then the bacteria liquid is mixed with compound nutrients and a gamma-polyglutamic acid according to the mass ratio of 1:1:0.05-0.1 to be prepared into the efficient liquid compound microbial fertilizer. On the basis of good phosphorus dissolving capability of the bacillus megaterium, good insect resistance of the bacillus amyloliquefaciens and good organic matter degrading capability of the bacillus amyloliquefaciens, the purposes of more excellent fertilizer efficiency and lower water consumption are achieved under the characteristics of water retention, fertilizer preservation, and no environmental pollution of the gamma-polyglutamic acid, therefore, the scientific and reasonable matching of the compound fertilizers is formed.

Description

technical field [0001] The invention belongs to the field of compound microbial bacterial fertilizer, and in particular relates to a liquid compound microbial fertilizer containing polyglutamic acid and a preparation method and application thereof. Background technique [0002] Among the top ten countermeasures for the protection of the ecological environment in my country, it is clearly advocated to promote "ecological agriculture", protect the ecological environment and farmland soil, promote the production of pollution-free and healthy food, and ensure that a sufficient amount of organic matter returns to the soil to promote the biological cycle in the ecosystem. To achieve the purpose of maintaining and enhancing soil fertility and biological activity. Microbial agents can prevent diseases and are non-toxic and harmless to humans and animals. They are the preferred means of production for the production of high-quality and pollution-free agricultural products. With the r...
