Microbial organic fertilizer and preparation method thereof

Abstract

The invention provides a microbial organic fertilizer and a preparation method thereof. The preparation method comprises the steps of strain culture, compounding and liquid submerged fermentation, and belongs to an agricultural integrated production technique. 15-20% of Bacillus mucilaginosus, 15-18% of Bacillus megaterium, 15-18% of Azotobacter chroococcum, 10-13% of Saccharomyces cerevisiae, 10-13% of Candida utilis, 15-18% of Lactobacillus plantarum and 10-13% of actinomycete are respectively subjected to primary and secondary strain culture and tertiary liquid submerged fermentation until the bacterial count in the fermentation liquid reaches 10-15*10<8> / mL, thereby obtaining the microbial organic fertilizer (707(Y)). By adopting the advanced liquid submerged fermentation technique and using the strains with high stability and functionality, which are screened from the natural world over the years and have the advantages of many varieties and convenient application method, the invention can promote the plant growth, improve the fruit quality, promote prematurity, increase the yield, enhance the utilization ratio of the fertilizer, improve the ecological environment of soil, and have certain effects of disease prevention and disease resistance.

Description

technical field

[0001] The present invention relates to a kind of microbial organic fertilizer and preparation method thereof, in particular, to a kind of microbial organic fertilizer rich in nutrients required for crop growth produced by effective compounding of different strains through synergy ( 707(Y)), which belongs to agricultural intensive production technology. Background technique

[0002] Biological fertilizers are products containing specific living microorganisms. They are applied to agricultural production. Through the life activities of the microorganisms contained in them, they can increase the supply of plant nutrients or promote plant growth, increase yield, improve the quality of agricultural products and the agricultural ecological environment. With the development of science and technology, the traditional chemical fertilizer industry is in deep trouble. New fertilizers have a broader development space in today's agricultural field due to the adoption of ...
