| 摘 要： | 就有限供水条件下谷子、春小麦的耗水特性进行了分析,结果表明:有限供水明显提高了谷子、春小麦的产量,少量水增产的原因不仅在于灌水本身,还在于灌水促进了作物特别是根系的向下生长,从而增加了作物对土壤深层储水的利用程度,有限水分起到了“以水调水”的作用,拔节期供水的作用特别明显.拔节期是谷子、春小麦有限供水的最佳时期.

| Abstract: | Water use characteristic ofmillet and spring wheat was studied under limited water supply. Result showed that limitedwater supply increased obviously yield and WUE of millet and spring wheat. The majorreason was not only small water itself, but also use extent increase of soil waterreservoir because limited water supply accelerate crop growth ,especially root growth.Limited water supply play the role of regulating and using soil water reservoir . Jointingstage was the best stage of limited water supply. |
