摘　　要：为了使棉花新品种邯棉10号得到更好的推广和种植,达到轻简化栽培的目的,于2019年在棉花打顶期,设置了不打顶、人工打顶和25%氟节胺悬浮剂不同用量打顶对比试验,来研究化学打顶剂对邯棉10号生长发育和产量的影响。结果表明:25%氟节胺悬浮剂可代替人工打顶,在1050~1200 ml/hm2浓度范围内对棉花生长发育具有较好的调节作用,并对籽棉产量的提高具有促进作用。在生产上可推广使用。In order to make the new cotton variety Hanmian 10 better popularized and planted,and achieve the purpose of simplified cultivation,the comparative experiment of no topping,artificial topping and 25%flutamide SC was set up in the topping period of cotton in 2019 to study the effect of chemical topping agent on the growth and yield of Hanmian 10.The results showed that 25%flutamide SC could replace artificial topping,had a good regulation effect on cotton growth and development in the concentration range of 1050-1200ml/hm2,and promoted the increase of seed cotton yield.It can be widely used in production.
