摘　　要：采用随机区组设计,比较52%烟嘧磺隆·莠去津可湿性粉剂不同施药剂量对夏玉米田杂草的防除效果及其对夏玉米产量和安全性的影响。结果表明,52%烟嘧磺隆·莠去津可湿性粉剂1.50～2.25kg/hm2对北方夏玉米田主要阔叶杂草和禾本科杂草药后15～30d的株防效和鲜质量防效均达95%以上,夏玉米产量比清水对照增加1.9%～4.7%,并且其对夏玉米安全,说明该药剂是防除夏玉米田主要杂草较理想的除草剂,适宜施药期为玉米3～5叶期、杂草2～3叶期。Randomized block design was employed to study the safety and control effect of different concentrations of 52% nicosulfuron·atrazine WP in summer corn field.The result showed that both the weed number and fresh weight control effect on broadleaf weeds and gramineae weeds in northern summer corn of 52% nicosulfuron·atrazine WP were greater than 95%（15～30 days after application）with 1.50～2.25 kg/hm2 application dosage,and the output of northern summer corn has increased 1.9%～4.7%,and it was safe to summer corn,which means that this herbicide was an optimum agent to control weeds in summer corn field and the suitable application period was at 3～5 leaf stage of corn and 2～3 leaf stage of weeds.
