摘要
在密植化控塑造较小个体组成适度群体的前提下，内位１～２果节着生有效铃的比率比对照提高１５％以上；１～２果节着生有效铃的比例与１０月份前收花量呈极显著正相关（ｒ＝０．９８５７＊＊），与１１月份后期棉花收获量呈极显著负相关（ｒ＝－０．９９１４＊＊），可使收花进度明显提高。获得这一早熟性能，是棉花生产早熟、高产、优质相结合的现实途径之一。
On the basis of the plant population composed by high density of smaller plants controlled by the chemical application, the rate of the available cotton bolls setted close to the main stem on 1～2nd fruiting position is 15% higher than that of the control. The available bolls on 1～2nd fruiting position close to the main stem was sighificantly positively related to the bolls opened before October with r=0.9857. However, it was negatively related to the bolls opened in late November with r=-0.9914, which made the boll openning earlier.
