摘　　要：以棉花栽培品种‘中棉所50’为材料,研究喷施不同浓度氟节胺代替棉花打顶的效果。结果表明,经氟节胺处理后,棉株长势旺盛、叶色浓绿,株高降低,顶部叶片变小,籽指增加,单铃重增加,籽棉重增加;氟节胺浓度为0.10 g.L-1(处理4)和0.08 g.L-1(处理5)时,皮棉重增加。各处理产量和品质性状较对照无明显变化。结果还表明,喷施氟节胺代替人工打顶,在达到整枝效果的同时,既避免了对棉花植株的物理伤害,又节省人工和时间。Effects of spraying different concentrations of flumetralin solution instead of topping on cotton variety Zhongmiansuo 50 in topping period were studied. The results showed that after using flumetralin, the plants grew vig- orously; the leaves showed invisible green and the plant height decreased, and the top leaves became smaller. The seed index, single boll weight and yield of seed cotton all increased. Lint cotton weight increased in the flumetralin concentration of 0. 10 or 0. 08 gL-1. There was no significant difference in yield and quality traits of cotton among different treatments. It can be concluded that cotton topping can be replaced by spraying flumetralin solution, which can achieve effects of cotton topping and pruning, avoid physical damage and save labor and time.
