为简化棉花栽培管理技术、降低植棉成本,以抗虫棉花新品种冀3927和冀棉3536为试验材料,设保留1条营养枝、2条营养枝和全部营养枝计3个处理,以去掉全部营养枝的常规整枝管理为对照（CK）,研究了保留不同数量营养枝对棉花产量和主要农艺性状的影响。结果表明：保留营养枝的棉花,铃数和果枝数增多,衣分、铃重和子指降低,子棉产量显著提高,黄萎病发病率降低。以保留1条营养枝效果最好,可以作为棉花省力化栽培的整枝方式。

To simplify the cultivation technique of cotton, and reduce the planting cost, using new insect-resistant cotton varieties Ji 3927 and Jimian 3536 as the materials, three treatments were set up including retaining one vegetative branch, two branches and all branches, the effects of number of vegetative branches on the yield and main agronomic characters were studied. The results showed that by retaining vegetative branches, the boll num- ber, branch number and seed cotton yield could be increased, the lint percentage, boll weight, seed index, and the incidence of VerticiUium wilt could be decreased. The effect of retaining one branch was the best, which could be used as the simplified training method.
