In conventional cultivation, the fertilization of crops mainly relies on chemical fertilizers, or the combination of chemical fertilizers and conventional organic fertilizers, but long-term large-scale application of chemical fertilizers will cause problems such as soil acidification, soil compaction, and a decrease in the richness of bacterial communities, which in turn will affect the ecological functions of cultivated land and soil. crop yield. At present, with the deepening of the concept of green development, the application of new fertilizers to improve soil performance and increase crop yield has become a research hotspot at home and abroad. It is imperative to use agricultural and forestry residues such as camellia oleifera husk, tea bran, vegetable and fruit peel, peanut bran, and traditional Chinese medicine residue through microbial fermentation liquid fertilizer as a new type of green and pollution-free fertilizer.

Fermentation tank is a device used for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plate. There are anaerobic fermentation and aerobic fermentation methods for organic fertilizer fermentation. Fertilizer fermentation tanks that require anaerobic fermentation are designed During processing, it is necessary to pay attention to the tight structure and reasonableness. A set of devices is needed to reduce air injection into the tank, and the microorganisms have the problem of barrel expansion during the fermentation process. The tank needs to be exhausted from time to time, so the fermentation tank needs to have exhaust devices and measurement Temperature entry and exit device; a stirring device is also required in the tank to increase biological activity and accelerate fermentation, but frequent opening of the lid will easily affect fermentation, and frequent contact of the fertilizer in the tank with air is likely to be contaminated with bacteria, because most of the bacteria used in microbial fermentation are mesophilic bacteria , such as mold, actinomycetes and general bacteria, their optimum growth temperature is generally 20 ~ 40 ℃. Temperature will affect the rate of various enzyme reactions, change the synthesis direction of bacterial metabolites, affect the metabolic regulation mechanism of microorganisms, affect the physical and chemical properties of fermentation broth, and then affect the kinetic characteristics of fermentation and the biosynthesis of products.
