摘  要：
在考虑降水蒸发蒸腾等影响一致的情况下,研究了常规灌溉、控制灌溉Ⅰ、控制灌溉Ⅱ、控制灌溉Ⅲ4种不同灌溉模式下水稻各生育期灌水量、产量性状,通过方差分析研究了不同灌溉模式对水稻产量的影响、灌溉水利用率并拟合得到灌水量与产量的回归方程。试验结果表明:各灌溉模式灌溉水利用率为控制灌溉Ⅰ>控制灌溉Ⅲ>控制灌溉Ⅱ>常规灌溉,图表中看出返青到分蘖末为需水非敏感期、拔节孕穗期和抽穗开花期为需水敏感期,不同灌溉模式对产量影响显著。控Ⅰ灌溉水利用率最高,能够达到节水增产的目的,合理利用水资源。

摘  要：
Considering the same influence of rainfall,evapotranspiration,this experiment studied water irrigation amount and yield traits for each growth period of rice under four modes,including conventional irrigation,controlling irrigation I,controlling irrigation Ⅱ,controlling irrigation Ⅲ.Through variance analysis,the effects of different irrigation modes on the rice production,irrigation water use efficiency are studied and the regression equations fitting for water and production are gotten.The results show that the order of irrigation water use efficiency of different irrigation mode from high to slow is controlling irrigationⅠ,controlling irrigation Ⅲ,controlling irrigation Ⅱ,and conventional irrigation;the insensitive period of water demand is green stage to late tillering stage;the sensitive period of water demand is jointing-booting stage and heading-flowering stage;different irrigation modes have significant effect on the yield.The controllingⅠtreatment can get the highest irrigation water use efficiency and achieve the purpose of water-saving,yield-increasing,and using water resources reasonably.
