摘　　要：通过主茎早摘心,以叶枝结铃为主的栽培措施可影响棉花结铃及铃重。其单铃重有两个高峰期,第1个在7月16日～25日,第2个在8月6～15目。在两个高峰期内所结棉铃的平均铃重分别比整株铃重高18.8％和12.7％。Through top shoot nipping in main stem, the caltivation method depending on boll - forming in vegetative branchs coald influence cotton boll - forming and its weight. There are two peaks in the boll -forming stage, one is Julyl6 to 25, and the other is August 6 to 15 .
