| 摘 要： | 利用3 a的试验资料,对夏玉米生长发育期间的气象条件、产量性状、水分利用效率(WUE)和水分-产量反应系数进行了分析.结果表明:夏玉米各个生长发育阶段水分亏缺对产量的影响不一样,其中抽雄期水分亏缺对产量的影响最大,水分-产量反应系数达1.443,说明这个阶段是灌水增产的关键期.

| Abstract: | The paper utilized experiment data of three years to analyze meteorological condition,yield character,water utilization efficiency(WUE) and reactivity coefficient between moisture and yield in the whole growth stage of summer corn.It was found that the different growth stage on summer corn yield was different;the affection of water stress in tasseling stage was the largest,in which the reactivity coefficient between moisture and yield reaches 1.443.This stage is the key period for irrigation and increasing yield. |
