摘要
为给南疆无膜棉生产提供技术依据,以中早熟品种中棉619、新陆中82号为材料,设置三种不同行距配置方式进行试验,分别为A:(76+76) cm,一幅三行;B:(76+10+76)cm,一幅四行;C:(10+66+10+66+10) cm,一幅六行,研究不同行距配置对无膜棉生长发育及产量的影响。结果表明,随着行距的增加,无膜棉单株优势增强,但群体优势减弱。A处理下新陆中82号的单株铃数、单铃重及两品种的干物质日增长速率最大,B处理下株高、茎粗、果枝数最大,C处理产量最高(中棉619产量6 748.3 kg/hm^(2),新陆中82号产量5 203.5 kg/hm^(2)),但与B处理无显著差异。综合生长发育指标和产量情况,B处理的棉花生长各项指标较优,产量较高(中棉619产量6 259.8 kg/hm^(2),新陆中82号产量5 092.6 kg/hm^(2)),增产潜力较大,适宜南疆无膜棉栽培。
To provide theoretical bases for production and cultivation of non-film cotton in southern Xinjiang, three kinds of row spacing configurations were set to study their effects on growth and yield of non-film cotton with Zhongmian 619 and Xinluzhong 82 as materials. The row spacing were set as(76+76) cm between three rows(A),(76+10+76) cm between four rows(B),(10+66+10+66+10) cm between six rows(C). The results showed that with the increase of row spacing, the single plant advantage of non-film cotton increased, but the population advantage decreased. The number of bolls per plant and single boll weight of Xinluzhong 82 and the daily growth rate of dry matter of the two varieties were the highest in treatment A;the plant height, stem diameter and number of fruit branches were the highest in treatment B;the yield of treatment C was the highest(6 748.3 kg/hm^(2)of Zhongmian 619 and 5 203.5 kg/hm^(2)of Xinluzhong 82). Comprehensively considering the growth and development indexes and yield, the cotton growth indexes were excellent under B treatment with higher yield(6 259.8 kg/hm^(2)of Zhongmian 619 and 5 092.6 kg/hm^(2)of Xinluzhong 82) and larger yield increasing potential, so the row spacing configuration of treatment B was suitable for non-film cultivation in southern Xinjiang.
