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
The six factors which have the greatest influence on the yield and the easiest control in cotton production were selected. Taking the dry cotton fields in Heilonggang Ecological Zone of Hebei Province as an example, 18 pilot districts in 1988 were chosen as examples. The mathematical model of comprehensive evaluation was used to study the effects of the mutual effect of density, row spacing, fruit branch number, base N fertilizer, bud N fertilizer and flower bell N fertilizer on the yield. Two optimized combinations of different types of cultivation measures were screened out. At the same time, the best agronomy measures package with the highest yield and different yield levels were defined
