In the crop water culture process, all the planting units are usually connected with each other, the nutrient solution of one planting unit is polluted, the whole nutrient solution of other connected planting units can be influenced frequently, and all the planting units can only use the nutrient solution with the same formula and the same concentration, so that the diversification and differentiation management of the cultivated crops are not facilitated.
In addition, the temperature of the nutrient solution can affect the dissolved oxygen of the nutrient solution, the growth of the root system of the crop, the absorption of nutrients and other physiological characteristics. The rhizosphere temperature suitable for the growth of crop roots is 18-22 ℃, and for high-quality hydroponic plants in summer, the temperature rise in summer can cause the temperature rise of nutrient solution, and the maximum temperature can reach more than 30 ℃. The excessive temperature can reduce the dissolved oxygen in the nutrient solution, enhance the respiration of the root system, accelerate the aging of the root system and inhibit the absorption of the root system to nutrients and moisture; and in winter, the temperature is low, so that the temperature of the nutrient solution is low, and when the temperature of the plant rhizosphere is low, the water metabolism, the mineral absorption and the like of the plant rhizosphere are reduced, so that the net assimilation rate is reduced, and the growth and development of crops are inhibited.
