摘要: 通过对叶面积指数、生物量、水分利用效率、灌浆速率等数据的分析发现:拔节期胁迫对冬小麦的产量和水分利用效率有一定的影响;充分灌水处理生物产量较高但是水分利用效率低;不同生育期水分胁迫的处理对土壤储水量的消耗有明显的不同最大相差13.3 mm;以棵间蒸发形式消耗的无效耗水也有明显的差异,最多相差20mm.

Abstract: Limited irrigation experiment was conducted under field condition with winter wheat. After analyzing the data about the biomass, LAI, the ratio of grain-filling, water use efficiency and evapotranspiration,it was found that the irrigation at the stem-elongation stage was efficient to WUE and crop yield; the sufficient irrigation could increase the biomass but reduce the water efficiency; the soil water consumed by different treatments were different and the maximal difference was 143.3 mm; the ineffective water-consumption through e-vaporation between plants of the different treatments were also different and the maximal difference was 20 mm.

Key words: Effects, Controlled irrigation, Growth development, Water efficiency, Winter wheat
