The requirement on water culture technology is high, the preparation, supply and regulation technology of the water culture nutrient solution is complex, and managers are required to have corresponding knowledge and skills. In hydroponics, in order to maintain the normal growth and development of crops, the nutrient solution must contain 13 essential elements, and they must be in an ion dissociation state which is a state that can be absorbed by plants, the proportion among ions must be appropriate, the concentration of the nutrient solution, the amount of liquid supply, the amount of oxygen supply, the pH value, the air temperature and the like must be precisely controlled, and the nutrient solution can make crops develop well and obtain high yield only if the above conditions are met.
In the water culture process, the pH value of the nutrient solution directly influences the nutrient solubility and the absorption condition of root system nutrients, but the pH value stability in the long-time planting process cannot be guaranteed in the conventional nutrient solution, and the pH value of the nutrient solution is kept within a certain range by human intervention, so that firstly, at least a measuring tool such as a pH meter needs to be prepared, and secondly, the pH value of the nutrient solution needs to be adjusted by acid, alkali and the like, the intervention means is difficult to realize and complicated to operate for non-professionals, and the storage of the acid, alkali and liquid in a home is very unsafe.
