对中棉所23号单株进行蕾、花、铃时空分布调查,统计不同果枝节位蕾、花、铃总数并计算开花率、成铃率。结果表明:1.不同节间、果节间蕾花铃数差异这极显著水平,第6、7、8、9节为结铃高峰部位,第5、16、17节则现蕾、开花成铃很少,不同果节间随离主茎越远现蕾、开花、成铃呈迅速下降趋势。2.单株开花率、成铃率是下部最高（54.92％,56.91％）,中部次之（38.51％,30.39％）,上部最低（16.57％,12.71％）单株铃数以中下部节位第一果节为主。3.不同节位间蕾铃脱落率不同,第10节脱落最重,1～8节落铃大于落蕾,9～13节则相反。
The investigation on the spatiotemporal distribution of buds, flowers and bell in Zhongmiansuo No. 23 was carried out. The total number of buds, flowers and bellies in different branches was counted and the flowering rate and boll rate were calculated. The results showed as follows: 1. There was a significant difference in boll number between different internodes and internodes, while the sixth, seventh, eighth and ninth were the boll boll sites, while the fifth, Few bells, with the farther away from the main fruit stems buds, flowering, bells were rapidly declining trend. The flowering rate per plant was the highest in the lower part (54.92%, 56.91%), followed by the middle part (38.51%, 30.39%) and lowest in the upper part (16.57%, 12.71% The first fruit-based festival. Different stages of different levels of different levels of buds off, the most off the tenth section, 1 to 8 drops than the falling buds, 9 to 13 is the opposite.
