Description
Technical Field

With the in-depth understanding of microbial fermentation process and the continuous progress of aseptic operation technology, aseptic sealed liquid seed fermentation technology came into being. The existing organic fertilizer fermentation processing operation is to place the strain raw material in the fermentation container. During the cultivation process of liquid strains, if the strain itself does not have sufficient fermentation capacity, it may be necessary to add additional fermentation agents to accelerate the fermentation process or improve the fermentation efficiency. Choose to add an appropriate amount of fermentation agent, stir after adding the fermentation agent, and then close the container for fermentation.
