Compounded amino-acid microbial bacterium agent and preparation method therefor

Abstract

The invention provides a compounded amino-acid microbial bacterium agent and a preparation method therefor. The microbial bacterium agent is prepared from the raw material ingredients in parts by weight: 38 parts of Sphingomonas yanoikuyae powder, 12 parts of Lactobacillus bulgaricus powder, 25 parts of Azotobacter chroococcum powder, 20 parts of Bacillus laterosporus powder, 9 parts of compounded amino acid salt, 20 parts of zymosan and 26 parts of choline chloride. The compounded amino acid salt contains L-histidine salt, L-cysteine salt, L-ornithine salt and L-lysine-L-aspartate, wherein the weight content ratio of the L-histidine salt to the L-cysteine salt to the L-ornithine salt to the L-lysine-L-aspartate is 5: 3: 2: 2. The compounded amino-acid microbial bacterium agent provided by the invention has the pH value of 6.8 and the moisture content of 18-22%; the content of effective living bacteria is 6.6-7.9*10<9> / g, and the ratio of miscellaneous bacteria is 3.2-4.7%.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and relates to a compound amino acid microbial bacterial agent, in particular to a compound amino acid microbial bacterial agent and a preparation method thereof. Background technique [0002] Ordinary chemical fertilizers and pesticides have made great contributions to agricultural development, but their negative effects are becoming increasingly apparent. Pesticide residues in crops threaten human health; excessive use of nitrogen fertilizers makes crops nitrate and nitrite exceed the standard, It has brought many negative effects to human health. [0003] At the same time, for the environment, a large amount of chemical fertilizers and pesticides have overloaded the environment, and many pollutions and residues cannot be completely decomposed for decades; causing soil compaction, soil quality has seriously declined, and the quality of crops has also been affected. [0004] Although there ...

AI Technical Summary

Problems solved by technology

[0005] In short, the existing microbial agents have the following defects: (1) low content of effective viable bacteria and high rate of miscellaneous bacteria; (2) not resistant to storage, effective storage time is short; (3) poor ability to inhibit harmful organisms in the soil
