| Abstract: | The crop water requirements and irrigation forecast are main parameters for the farmland moisture management.The real-time irrigation forecast is the base for the decision of dynamic irrigation schedule and plays an important role in saving water,increasing crop yields and economic benefits.Taking the corn in entire period as the study object and combining each parameter in different growth stage,the calculation of crop water requirements and the irrigation forecast are conducted in this paper.The results show that the forecast system has good practical application value. |
