| Abstract: | According to the water conditions in each growing stage of rice in the well's irrigation area at Sanjiang Plain, the experimental treatments are designed. Through analyzing and selecting of different models. a water production function appropriated to Sanjiang Plain is established. At same time, the variable law of sensitivity index during the whole growing season of rice is studied. This result provides a scientific basis for optimum irrigation schedules of rice under the deficient irrigation. |
