| 摘 要： | 选择了棉花生产中对产量影响最大而又最容易控制的６个因子，以河北省黑龙港生态区旱地棉田，１９８８年１８个试验小区为例。采用综合评判的数学模型，研究了密度、行距、果枝数、基Ｎ肥量、蕾Ｎ肥量、花铃Ｎ肥量的相互效应对产量的影响。筛选出了２组不同类型栽培措施的优化组合。同时明确了最高产量及不同产量水平的最佳农艺措施配套方案

| Abstract: | In this paper, the alternute effect of plant density, row spacing, sympodium branches, first basement N. basement N at square stage, basement N at bloom stage on yield of dryland cotton in Heilonggang Ecologcial Region in Hebei province were studied .(Taking 18 experimental areas of 1988 as an example). The six factors were the most important and control easyly. Based on these mathematical modelings of synthetical judge, the superior combinations of two different kinds of cultural measures were selected. |
