Description

Technical Field

[0001] The invention relates to the field of composite microbial agent fermentation and culture, and in particular to a composite microbial agent fermentation and culture device. Background Art

[0002] Composite microbial agents are currently widely used in agriculture. They can degrade the allelopathic substances secreted by the roots of previous crops, regulate the soil microecological environment, increase the soil organic matter content, and promote plant growth. They not only provide nutrients for crops, but their effective bacteria can also secrete active substances such as gibberellins, cytokinins, and auxins to stimulate, regulate, and promote the growth and development of crops, inhibit the reproduction and growth of pathogens, or induce plant immunity and increase plant resistance to diseases.

[0003] Currently, most composite microbial agents are cultured using liquid fermentation. Microorganisms need to be cultured and propagated at appropriate temperatures, ventilation conditions, and pH levels. The culture solution must be added to the culture tank during different culture processes and the culture solution must be fully mixed.
