采用人工控制土壤含水量的方法，对冬小麦水肥产量的交互效应研究结果表明，增加施肥量可提高冬小麦对土壤水分的利用程度，但低供水高施肥和高供水低施肥土壤水分的无效消耗增加，不利于提高水分生产效率。要获得理想产量必须量水施肥，才能提高水分生产效率。
The results of interactive effects on the water and fertilizer yield of winter wheat by artificial control of soil water content show that increasing the amount of fertilizer can increase the degree of soil water utilization in winter wheat. However, the ineffective consumption of high water and low water fertilization soil moisture increases, Not conducive to improving water production efficiency. In order to obtain the ideal yield, it is necessary to apply water and fertilize it in order to increase the water production efficiency.
