| Abstract: | Through the experiments on different soil water grades and duration in the small partitioned field under the condition of water controlling, analysis is conducted on the effects of water stress on the physiology, ecosystem and yield of wheat. Discusses are made on the lag and compensation effect of rewatering corresponding to different water stress. The results show that the critical relative soil moisture index corresponding to slight water stress is 55%, which is advantageous for obtaining the high yield. |
