Warehouse type aging preparation method for microbial organic fertilizer

Abstract

The invention relates to a preparation method for a microbial organic fertilizer, and particularly relates to a warehouse type aging preparation method for microbial organic fertilizer. The warehouse type aging preparation method comprises an organic material pretreatment step, a primary fermentation step in a fertilizer plant fermentation workshop, as well as a fermentation warehouse aging step, wherein the fermentation warehouse aging step comprises the steps: transferring the fermentation materials with less than 45% of moisture rate, obtained in the primary fermentation step in the fertilizer plant fermentation workshop, into a fermentation warehouse for storage type aging for 8-10 days, stabilizing the aging temperature at 40DEG, completing the storage type aging after the moisture rate of the materials is reduced to 30%, and performing finished product processing and packaging steps to the aged fermentation materials. The fermentation warehouse is utilized for continuing secondary fermentation, namely aging, to the non-entirely thoroughly decomposed materials which are subjected to primary fermentation, volatile substances in organic matters can be decreased, and parasitic ova and pathogenic microorganism can be further killed so as to achieve harmless purpose.

Description

technical field [0001] The invention relates to a method for preparing microbial organic fertilizers, in particular to a method for preparing microbial organic fertilizers for storage-style aging. Background technique [0002] The traditional use of livestock and poultry manure or crop straw to make organic fertilizer is the oldest preparation method of microbial organic fertilizer. Although the high temperature generated during the retting (composting) process can kill some pathogenic microorganisms to a certain extent, it still causes soil-borne diseases and cannot effectively control pests and diseases. At present, with the application of fermentation engineering, microbial engineering and other related disciplines in agricultural microorganisms, the sterilization and cultivation of beneficial bacteria in the fermentation process of microbial organic fertilizers have been improved, but the existing fermentation process is basically a one-time fermentation process. The ma...

Problems solved by technology

[0003] The present invention aims to solve the problem of incomplete fermentation of organic materials and difficulty in inhibiting the growth of spoilage bacteria in the fermentation process of the above-mentioned microbial organic fertilizer, and provides a method of using a fermentation chamber to continue to carry out secondary fermentation of materials that have not yet reached full maturity after the first fermentation. Fermentation is aging, which reduces the volatile substances in organic matter, further kills parasite eggs and pathogenic microorganisms, and achieves the purpose of harmless microbial organic fertilizer storage aging preparation method
