In the process of smart water conservancy construction in Shule River Basin,according to the requirements of precision irrigation of farmland crops in digital twin irrigation area,in order to grasp the water benefits of different crops under different irrigation modes,this paper analyzes the water benefits of wheat,corn and sunflower widely planted in Shule River Irrigation area,and the corresponding data were obtained.The experiment shows that the water benefit of different crops is the highest under drip irrigation mode,and the water benefit of traditional flooding irrigation mode is the lowest,which can not meet the requirements of modern irrigation area construction.Therefore,vigorously popularizing water-saving irrigation technology in Shule River irrigation area is an inevitable requirement for the construction of modern irrigation area.
