摘　　要：玉米苗期除草是减少病虫基数的重要方法之一,本试验通过对7种常用除草剂在玉米田进行杂草防除研究,结果表明:各处理除草剂在示范剂量内对玉米很安全,处理2、4防治成效较差,处理1、3、6、7防治成效均较好。综合考虑防效成果和经济效益,建议应用28%烟嘧·莠去津可分散油悬浮剂90 mL/667 m^(2)。Weed control during the seedling stage of corn is one of the key methods to reduce the incidence of pests and diseases.This study evaluated the efficacy of weed control in corn fields using seven commonly ap-plied herbicides.The results indicated that all herbicide treatments within the recommended dosages were safe for corn.Treatments 2 and 4 demonstrated lower control efficacy,while treatments 1,3,6,and 7 exhibited higher control efficacy.Considering both efficacy and economic benefits,the application of 90 ml per 667 m^(2) of 28%ni-cosulfuron-atrazine dispersible oil suspension is recommended.
