Abstract

The invention discloses microbial fertilizer and a preparation method thereof. The microbial fertilizer is fermentation liquor with hydrogen-oxidizing bacterium content ranging from 1X108 / mL to 1X1010 / mL or mixture of hydrogen-oxidizing bacterium liquid and sterile grass carbon, the content of hydrogen-oxidizing bacteria in the mixture ranges from 2X108 / g to 2X1010 / g, moisture of the mixture ranges from 20wt% to 40wt%, and the hydrogen-oxidizing bacteria include one type or a plurality of types of a flavobacterium, a pseudomonas, alcaligenes and burkholderia. The invention further provides a preparation method of the microbial fertilizer. The microbial fertilizer realizes a fine application effect for plants, and is free of environmental pollution, low in consumption and easy in popularization, the preparation process of the microbial fertilizer is simple, the production cycle is short, and cost is low.

Description

technical field

[0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a microbial fertilizer and a preparation method thereof. Background technique

[0002] Because of its ability to improve soil, improve soil fertility, improve the absorption and utilization of plant mineral elements, enhance the disease resistance and drought resistance of crops, increase yield, and improve quality, microbial fertilizers are used in the development of green agriculture, ecological agriculture, and the production of safe and pollution-free agricultural products. It shows an irreplaceable role. In particular, Plant Growth Promoting Rhizobacteria (PGPR for short) directly or indirectly promotes plant growth through one or more growth-promoting mechanisms.

[0003] At present, microbial fertilizers are mostly concentrated in rhizobia fertilizers, nitrogen-fixing bacteria fertilizers, phosphorus-solubilizing fungi fertilizers, and potassium-...
