| 摘 要： | 根据大量的田间试验资料，分析了供水不足情况下水分胁迫对棉花生长发育及产量的影响，其影响程度由大到小依次为：现蕾＞花铃＞吐絮＞苗期，蕾期和花铃期连续受旱对棉花生长发育及产量的影响最大。利用国际上常用的几种同时考虑供水时间和灌溉水量的作物水分生产函数模型，经计算、分析、比较，找出了适合河北省棉花水分生产函数模型的具体表达形式，并进一步说明蕾期和花铃期两阶段的水分条件对棉花产量致关重要。

| Abstract: | Based on a lot of experiments on farm field, the effect of moisture coerce on growing and yield of cotton were analyzed. The experimental result showed that the most sensitive period of moisture of cotton is bud period, the cotton being in moisture coerce during the flower and bud period would make the cotton yield decrease a lot. Using the models of dated water production function that are most popular in internationality, the suitable cotton model of water production function in Hebei region was obtained. |
