Method for preparing composite biological fertilizer by combined solid fermentation of double bacterium

Abstract

The invention relates to a method for preparing a composite biological fertilizer from tremellose bacillus and gigantochromoblast, which comprises: culturing and growing secondary tremellose bacillus strain and secondary gigantochromoblast strain; then, (1) stirring the solid culture medium uniformly, and placing into a disinfected solid fermentation pool, wherein, the weight percentage of the components are: wheat bran 15-25%, straw 25-36%, fly ash 11-19%, bean cake powder 3-9%, CaCO3 0.3-0.9%, turf 7.5-14%, K2HPO4 0.1-0.6%, sucrose 1-5%, and fertilizer soil 9-15%; (2) inoculating the two secondary strains into the solid fermentation pool according to that: the inoculation amount is 20% of the total weight, while the amount of the secondary tremellose bacillus strain is twice of the secondary gigantochromoblast strain; (3) adding water into the solid fermentation pool to keep the humidity of the ferment material at 50%, sealing and controlling the temperature in the solid fermentation pool, and fermenting and growing for 48-54 hours to obtain the finished product. The invention adopts combined solid fermentation of double bacterium, accelerates the strain breeding speed, shortens the fermentation period, reduces production cost, and improves the blastema formation ratio of the product.

Description

technical field [0001] The invention relates to microbial fertilizer production technology, in particular to a method for preparing compound biological fertilizer by using jelly-like bacillus and megaterium bacillus. Background technique [0002] In the prior art, microbial fertilizers are usually fermented with a single bacterial species in a separate liquid, and then stirred with solid attachments to produce a single-performance microbial fertilizer. In recent years, there have also been reports on the development of composite bacterial agents, but the fermentation production process used is basically that each strain is fermented in liquid alone, and then mixed with solid attachments. For example, people such as Tang Xinyun reported some problems in the production and application of compound microbial fertilizers in the article "Microbiological Fertilizer and Its Production and Application" ("Journal of Biology", Volume 18, No. 1, February, 2000).

Problems solved by technology

Generally speaking, the production of microbial fertilizers currently used is only to purchase strains for fermentation and mix them with solid attachments by physical stirring. Not only the fermentation cycle of strains is long, the production cost is high, but also the product performance is not good due to random compounding. Stable, so that the sporulation rate of the product is low, and the quality is difficult to guarantee
