在人工控制水分条件下 ,通过田间小间隔不同水分等级和持续时间试验 ,分析了水分胁迫对小麦生理、生态及产量的影响 ,探讨了小麦对不同水分胁迫后复水的滞后作用和补偿效应 ,得出了有利于小麦高产、高效的轻度水分胁迫临界土壤相对湿度指标为 55% .
Under artificial control of water conditions, the effects of water stress on the physiological, ecological and yield characteristics of wheat were analyzed by field experiments with different water levels and durations. The lag effect and compensation effect of wheat on water recovery after different water stress were discussed. The critical soil relative humidity index of 55% was obtained for light water stress which is good for high yield and high efficiency of wheat.
