Abstract

The invention provides a high-inorganic nitrogen-sourced biological compound fertilizer and a preparation method thereof. The fertilizer contains the following functional bacteria: bacillus megaterium, bacillus subtilis, saccharomyces cerevisiae, lactobacillus plantarum, Mucor abundans and streptomyces albus. The content of inorganic nitrogen of the compound fertilizer can be as high as 35 percent, while the number of live bacteria can still be up to 2*10<10> cfu / kg. Experiments show that the field fertilizer efficiency of the compound fertilizer is significantly improved.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a biological compound fertilizer under a high nitrogen source, and also relates to a preparation method thereof. Background technique [0002] The fertilizer industry has always been divided into three types: organic fertilizer, inorganic fertilizer and microbial fertilizer. In recent years, due to concerns about the environment, agricultural product health and chemical fertilizer pollution, many manufacturers have begun to produce various compound fertilizers. The main products include biological compound fertilizers and organic compound fertilizers. two kinds. Among them, bio-organic fertilizer is the use of microbial agents to ferment organic waste to produce organic fertilizer, which has high biological activity but low content of available nutrients, and is limited by the unstable fertilizer efficiency of bio-fertilizer; organic compound fertilizer is composting of organic waste Aft...
