| Abstract: | A calculation method of the economic irrigation norm of the spring wheat is given in this paper based on the uncooperation condition of water and cultivated land resources and the farmland irrigation experiment results and considering the input and output of crop planting. The comprehensive benefit of the water and cultivated land resources can be fully brought into play by using the economic irrigation norm. |
