| 摘 要： | 为实现豫西半旱地区冬小麦节水高产栽培,提高水分利用效率,利用农田秸秆覆盖试验技术,研究了3种灌水模式下不同秸秆覆盖量对冬小麦生育期耗水量、作物产量以及水分利用效率（WUE）的影响。研究结果表明：秸秆覆盖对千粒重、穗粒数和产量的增长具有明显的促进作用,对公顷穗数的增长具有抑制作用。灌3水处理与灌4水处理相比较,产量与水分利用效率随覆盖量增加明显提高,产量和水分利用效率提高1.0%和1.6%,耗水量减少4%,实现了节水与高产的统一。灌2水处理下不同覆盖量的耗水量和水分利用效率都有所提高,但对产量影响不显著。试验最佳分配方案为灌3水处理与4 500 kg/hm2覆盖量。

| Abstract: | To achieve water-saving and higher production of winter wheat in arid areas of western Henan Province,effects of different straw mulching quantities on water consumption,grain yield and water use efficiency(WUE) in three irrigation models are studied by straw mulching experiments.The results show that with the increase in quantity of straw mulching,the increase in 1000-grain weight,grain yield and grain numbers are promoted greatly,and the increase in the number of spikelets in every hectare is restrained.W... |
