| 摘 要： | 以冀芝3号为试材,在播种后第2 d喷施41%草甘膦异丙铵盐水剂、50%乙草胺和25%绿麦隆可湿性粉剂,研究不同除草剂种类对田间杂草防治效果以及芝麻产量的影响,以筛选出适宜芝麻芽前除草的除草剂种类。结果表明：50%乙草胺对1 a生禾本科杂草和阔叶杂草芽前除草效果较好,且芝麻产量最高（689.28 kg/hm2）,对芝麻基本无药害,是较理想的芝麻芽前除草剂。

| Abstract: | The weeding effects of 41% glyphosate isopropylamine,50% acetochlor and 25% chlorotoluron WP before emergence of sesame Jizhi No.3,and their effects on the yield of sesame were studied.The results showed that the effect of 50% acetochlor was better for annual grass weeds and broadleaf weeds.Without ply totoxicity,and the yield of sesame was the highese（689.28 kg/hm2）,which was the ideal preemergence herbicide for sesame. |
