摘要 根据旬等量供水耗水模型,把作物耗水及其剩余量的变化分解为由供水的偏移与耗水力作用所引起,则耗水与剩余强度是时间的函数,并受生育期环境条件的强烈约束,作物生育期供水特性与湿润度就决定了作物耗水与剩余量. Based on the model of the equal water supply and consumption in ten-day period,if the change of water onsumption and remainder in crop is caused by the deviation of water sup-ply and power of water consumption,the intensity of consumption and remainder water is the function of time.Water consumption and remainder in crop is determined by the characteristics of water Supply and humidity in crop growing season.
