| 摘 要： | 通过模拟大田条件下不同生育阶段的水分亏缺对小麦生长发育的影响,分析了不同生育期缺灌水处理对春小麦产量的影响.结果表明,任一时期的缺灌处理都会使产量降低,但不同时期缺灌处理对产量构成因素的影响不同,缺灌拔节水的处理B的产量较对照减产最多,主要是因为穗数和每穗粒数都较对照减少;缺灌分蘖水的处理C的产量较对照降低,主要是因为穗数较对照下降;而缺灌开花水的处理D和缺灌麦黄水的处理E的产量较对照降低,主要是因为粒重较对照降低的缘故.

| Abstract: | Through simulating the effects of water deficiency of different growth stage in field condition on the growth and development of spring wheat,this paper analyzed the influence of water deficiency in different growth stage to the spring wheat yield.The result showed that the yield was reduced if there was not enough irrigation during any stages,but the influence to the yield components was different with the different stages.The yield for the treatment of irrigation lacking in shooting stage was lowest owing to the reducing of spike quantity and grain quantity.Because of the reducing of spike quantity,the yield of irrigation lacking in tillering stage is lower than that of control group,but the reason for the yield reduction of the treatment of irrigation lacking in flowering stage was the reducing of grain quantity. |
