中稻水分生产函数及优化灌溉制度研究

Study on Semi-late Rice Water Production Function and Optimal Irrigation Regime

通过对水稻各生育期干旱程度的控制 ,使水稻有意亏水 ,研究稻田水分不足条件下蒸发蒸腾量与产量的数学关系 ,为在水资源量一定的条件下 ,有效、及时的供水 。

Semi-late rice water production function in condition of water deficit is discussed with degree of drought control in rice growth periods. It provides basis to irrigation in time and availability under the limited water quantity.
