weighing glucose, sodium glutamate, citric acid, aspartic acid, nicotinic acid, vitamin B1 and vitamin B2 according to the proportion, then placing the materials into a reaction kettle, adding distilled water, and stirring the materials in the reaction kettle after adding the distilled water.
Glucose, sodium glutamate, citric acid, aspartic acid, nicotinic acid, vitamin B1 and vitamin B2 are all food grade. The distilled water is heated to 60 ℃. The stirring speed is not less than 300 revolutions per minute in the preparation process. The stirring time is not less than 30min in the preparation process. Glucose, sodium glutamate, citric acid, aspartic acid, niacin, vitamin B1, vitamin B2 are all dry weight measurements. Within the corresponding condition range, the produced biological activator can achieve the best effect of stabilizing water quality in the aquaculture process.
Example 2
