摘要
棉花开心株型栽培,通过主茎早摘心,以叶枝结铃为主,影响了棉花结铃及铃重。其单铃重的时间变化,呈两个高峰期,第1个高峰期在7月16～25日,第2个高峰期在8月6～15日。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％。棉田整体和个体结构合理,使棉花结铃多,铃重高。
The cultivation of nipping cotton, through the top removing of the main stalk, and depending on the boll - forming of leafy shoot, influence the boll - forming and weitht of bolls of cotton. There are two peaks in the boll- forming stage, that are July 16 to 25 and August 6 to 15.
