摘　　要：环嗪酮、敌草隆和莠灭净按设定的比例混配后,采用温室盆栽法进行活性测定和安全性试验。结果显示:使用混配后的除草剂组合,对光头稗子的活性比莠灭净明显提高,对甘蔗品种安全性为桂糖28号>粤糖128号>新台糖22号,其混剂对新台糖22号的安全性略高于莠灭净的安全性。表明环嗪酮、敌草隆和莠灭净混配组合对供试杂草的活性和甘蔗的安全性高于莠灭净。Hexazinone,diuron and ametryn were mixed at a set proportion, activity and security experiments were conducted through plot culture in greenhouse. Results showed that activity of the mixed herbicide combination, significantly improved in sugarcane field on Echinochloa colonum （L.） Link. Compared with the ametryn, safety of sugarcane arieties was Guitang No. 28〉Yuetang No.128〉ROC22. Combination of hexazinone, diuron and ametryn was safer than ametryn in the test.
