摘　　要：采用随机区组设计,比较720 g/L异丙甲草胺乳油不同施药剂量对花生田杂草的防除效果及对花生产量和安全性的影响。结果表明,720 g/L异丙甲草胺乳油1.50～2.25 kg/hm(2制剂量)于花生播后苗前施用,药后15～35 d对花生田主要禾本科杂草、阔叶杂草株防效和鲜质量防效均达95%以上;花生产量比清水对照增加12.6%～27.5%,且对花生安全,说明该药剂是防除花生田主要杂草较理想的除草剂。Randomized block design was employed to study the safety and control effect of different spraying dosages of 720 g/L metolachlor EC in peanut fields.The result showed that： both the weed number and fresh weight control effect on broadleaf weeds and graminanous weeds in peanut field of 720 g/L metolachlor EC were greater than 95%（15～35 days after application） with 1.50～2.25 kg/hm2 application dosage,the output of peanut increased 12.6%～27.5%,and it was safe to peanut,which suggested that the herbicide was an optimum agent to control weeds in peanut field.
