The proper use of agricultural liquid microbial agents can increase the output of agricultural products, improve the land environment, and increase crop yields. Microbial agent storage tanks are indispensable equipment for the storage of liquid microbial agents. When using microbial agent storage tanks to store liquid microbial agents, it is necessary to pay attention to the oxygen and temperature required for the growth of liquid microbial agents.
