摘要
香附子为甘蔗田间恶性杂草,严重影响甘蔗生产。采用田间小区试验方法进行4种除草剂防除蔗田香附子的田间药效试验,结果表明:56%香莎一剑WP在杂草4～6叶期施用可有效防除香附子,药后45 d株防效及鲜重防效均超过92.0%,对甘蔗安全性好,田间推荐剂量在840～1680 a.i.g/hm2为宜。
Cyperus rotundus L.was a destructive weed in sugarcane field and caused serious damage to sugarcane production.Field plot experiment of four herbicides against Cyperus rotundus L.in sugarcane field was conducted.The result showed that XIANGSHAYIJIAN 56 %WP at the doses of 840 to 1680 a.i.g/hm2 had relatively good control effect on the 4-6 leaves of Cyperus rotundus L.and other broadleaves.After 45 days of application,its control efficiency against Cyperus rotundus L.was above 92.0 %,and it was safe to the sugarcane at the recommended rate of application.
