A kind of micro-ecological flora of crop root probiotics and its application

Abstract

The invention discloses a micro-ecological flora of crop root system probiotics and an application thereof. The micro-ecological flora comprises a leading flora, a balance flora, a basic flora, a secondary-function flora and a special-function flora, wherein the leading flora comprises 25-35 parts of nitrogen-fixing bacteria by mass; the balance flora comprises 17-23 parts of phosphate solubilizing bacteria and 17-23 parts of potassium solubilizing bacteria by mass; the basic flora comprises 2-7 parts of yeast, 2-7 parts of rhizobia and 2-7 parts of photosynthetic bacteria by mass; the secondary-function flora comprises 2-7 parts of bacillus and 2-7 parts of actinomycetes by mass; the special-function flora comprises 2-4 parts of white rot fungi and 1-3 parts of pseudomonas. In the micro-ecological flora disclosed by the invention, the strain stability is good, functional microorganisms can be effectively planted in soil, and the functions of improving the crop yield and quality, improving the soil, detoxifying heavy metals and resisting diseases and pests can be realized.

Description

technical field [0001] The invention relates to a micro-ecological flora of crop root probiotics, and also relates to the application of the micro-ecological flora in the preparation of organic fertilizers, belonging to the field of biological fertilizers. Background technique [0002] Over the past half century, the amount of chemical fertilizers used in my country has increased significantly, which has played an important role in ensuring the increase of grain production. However, due to the excessive application of chemical fertilizers, a series of social problems such as low fertilizer utilization rate and deterioration of ecological environment have been caused. [0003] Microbial fertilizers, also known as bacterial fertilizers, biological fertilizers, inoculants, etc., refer to a class of specific products containing living microorganisms. When used in agricultural production, crops can obtain specific fertilizer effects to promote crop growth, increase yield, and imp...

AI Technical Summary

Problems solved by technology

[0006] 1. The basic research on strains is backward: the interaction between strains is uncertain, the incompatibility and degradation of strains colonized in soil, the classification status of strains is not clear, and the strains used in some products lack necessary identification materials, which are not Conducive to the standardization and commercialization of products;

[0007] 2. The colonization rate of strains in the soil is poor: there are a large number of indigenous rhizobia in the soil with strong competitive ability and low nitrogen fixation ability, resulting in poor colonization of the applied microorganisms;

[0008] 3. The survival time of the bacteria is short, and the product quality is unstable
