Abstract: A control method for preparing crop nutrient solution, applied in a regulating device, obtains growth data of crops, and determines a growth state of the crops according to the growth data of the crops. The proportion of the nutrient solution required by the crops is determined according to the growth states of the crops, and the culture solution is adjusted according to the proportion of the nutrient solution. After a preset time period, updated growth state of the crops is determined. When the culture solution does not meet the proportion of the nutrient solution corresponding to the updated growth state, the culture solution is adjusted again until the culture solution meet the proportion of the nutrient solution corresponding to the growth state of the crops.
