The present disclosure relates to the technical field of water management in the wheat production process, and specifically relates to a precise irrigation method based on the water demand characteristics of the winter wheat in the Yellow River irrigation 5 area. The irrigation period and the irrigation water amount is determined based on the growth period of the winter wheat and the leaf water potential of the wheat, and the precise irrigation is performed. In the precise irrigation method based on the water demand characteristics of winter wheat in the Yellow River irrigation area provided by the present disclosure, the precise irrigation management method based on the winter 10 wheat water demand in the Yellow River irrigation area is combined with the wheat growth cycle and the leaf water potential to judge the irrigation period and the irrigation water amount, thereby realizing the scientific management of the water demand of the winter wheat in the Yellow River irrigation area. The precise irrigation method can significantly improve irrigation water utilization in the Yellow River irrigation area, and 15 greatly reduce the irrigation water amount, thereby achieving the effect of saving labor and environmental protection.
