| Abstract: | The irrigation water forecasting models of rice is presented in the paper based on water balance equation in rice farmland. The parameters are calibrated using historical irrigation water supply and rainfall data, then irrigation water demand of rice is calculated to forecast practical irrigation water amount according to predicted rainfall in the irrigation area. The presented formula can be used for irrigation area, where crop constitution is not clearly. |
