| 摘 要： | 用轻度、中度、重度三种不同调亏灌溉量,在冬小麦浇灌冻水和拔节水时进行调亏处理,结果显示,重度调亏处理在比正常灌水量减少40%的情况下,产量、千粒质量和穗粒数均低于对照,分别比对照减少56.25 kg、6.2 g和5.7粒;中度调亏处理在比正常灌水量减少25%情况下,产量、穗粒数也呈下降趋势,但差异不明显;轻度调亏处理在比正常灌水量减少15%情况下,产量、千粒质量、穗粒数等项指标或高于对照或等同于对照。

| Abstract: | Winter wheat irrigation amount was conducted by three treatments as low,middle and high-grade regulated deficit before over winter and at stem elongation stage.The results showed that the yield,one thousand grains quality and grains per ear of high-grade regulated deficit treatment(60% of normal irrigation amount) were lower than that of CK,and decreased by 56.25 kg,6.2 g and 5.7 grains respectively.The yield and grains per ear of middle-grade regulated deficit treatment(75% of normal irrigation amount) were also lower than that of CK,but the difference was not significant.The yield,one thousand grains quality and grains per ear of low-grade regulated deficit treatment(85% of normal irrigation amount) were equal or higher than that of CK. |
