Azotobacter-rich high-activity rhizobium strain and production technology of processing organic fertilizer of azotobacter-rich high-activity rhizobium strain

Abstract

The invention discloses an azotobacter-rich high-activity rhizobium strain and a production technology of processing an organic fertilizer of the azotobacter-rich high-activity rhizobium strain. The production technology comprises the following steps of by taking the azotobacter-rich high-activity rhizobium composite strain as a strain, performing micro oxygen consumption fermentation on various bio-wastes and livestock manures, and performing dewatering and pelletizing (or crushing) to prepare a pure organic fertilizer (or an organic biological composite fertilizer). As a rhizobium flora is relatively high in the content of azotobacter, is strong in the bioactivity, can greatly convert the bio-wastes to nitrate nitrogen, ammoniacal nitrogen, organic acid and organic matters by being mutually matched with saccharomycetes, rhizopus oryzae and basidiomycetes and matched with proteins, hydrolase, sucrose, cellulose and ligninase in the saccharomycetes, the rhizopus oryzae and the basidiomycetes together under the condition of half oxygen consumption and micro oxygen consumption so as to become necessary nutrient including nitrogen, phosphorus and potassium matters to agricultural andforest crops and economic crops and better solves the utilization problems of various bio-wastes.

Description

technical field [0001] The invention relates to a highly active rhizobia strain rich in nitrogen-fixing bacteria and a production process for processing organic fertilizer, belonging to the technical field of microbial fermentation fertilizer production. Background technique [0002] Bio-organic fertilizer is a kind of fertilizer with the effect of microbial fertilizer and organic fertilizer, which is compounded with specific functional microorganisms and various organic substances after harmless treatment and decomposing. It can improve the physical and chemical shape of the soil, enhance the ability of the soil to hold water, keep fertilizer, and supply fertilizer. The beneficial microorganisms contained in it enter the soil and form a symbiotic relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, and play a role in colonization. The synergistic effect of beneficial bacteria produces a large n...

Problems solved by technology

[0003] Patent application number ZL02113756.0 discloses a production process for processing organic bio-composite fertilizers from biological waste. After sixteen years of continuous exploration and improvement, the inventor, Fu Lizhong, realized that the patented technology itself only uses soybean root nodules. Bacteroids are used as strains, so that this technology can only decompose biological waste with high protein content as the main nitrogen source, while for industrial and agricultural production wastes containing a lot of cellulose, even wastes containing a lot of lignin The nutrients contained in the fertilizer are not fully utilized. Due to the defects of this patented technology, it is greatly unfavorable to process various biological wastes (including livestock and poultry manure) into pure organic fertilizers (or organic biological compound fertilizers).
