| 摘 要： | 采用田间试验的方法,测定了38%丙炔氟草胺·二甲戊灵ZC对覆膜棉田恶性杂草龙葵的防除效果及对棉花出苗生长的影响。结果显示,38%丙炔氟草胺·二甲戊灵ZC于棉花播前土壤封闭处理有效剂量为855~1710 g/hm2,对靶标杂草龙葵的株防效在30 d后达到88.5%~95.5%,60 d仍维持在93.9%以上,鲜重防效93.9%~98.9%,这对棉花相对安全,但超剂量施用时遇持续性低温多雨对棉花出苗生长有一定的风险。

| Abstract: | Field experiment method was conducted to study the control effect of Flumioxazin+Pendimethalin 38% ZC on Solanum nigrum in film covered cotton field and influence on emergence and growth of cotton.The results showed that soil closure treatment with effective dose 38% flumioxazin+pendimethalin ZC 855-1710 g/hm2 before cotton sowing,the control effect on the target weed Solanum nigrum was 88.5%-95.5% after 30 d,and maintained more than 93.9% after 60 d,and the control effect of fresh weight was 93.9%-98.9%,which was relative safe for cotton.Overdose application of flumioxazin+pendimethalin 38% ZC had a definite risk to cotton seedling emergence and growth under continuous low temperature and rainy weather. |
