西藏春小麦不同生育期缺灌对产量和水分利用效率的影响

Studies on Effects of Irrigation Systems on the Grain Yield Constituent And Water Use Efficiency of Spring Wheat in Tibet

作物对干旱胁迫的研究不仅涉及水资源的高效利用,而且也涉及粮食生产问题,因而显得尤为重要,本文利用2011年度春小麦田间试验资料,研究了春小麦不同生育期灌水处理对冬小麦产量和水分利用效率的影响,为揭示作物的高效用水机制提供科学依据。

The response of crops to drought stress involves not only the research of highly effective water resources use,but also the grain Production. So it is very impartment. In the paper,by using experimental data of spring wheat planted in 2011,the effects of irrigation Treatments indifferent growth stage on the grain yield constituents and water use efficiency of spring wheat were studied,which will helpful to provide theoretical basis for different phase response.
