摘　　要：为筛选出适合黄淮地区夏芝麻田土壤封闭的安全型除草剂,我们分别在2018和2019年开展田间试验。结果表明,960 g·L^(-1)精异丙甲草胺EC 900 mL·hm^(-2)处理的土壤对夏芝麻田阔叶杂草和禾本科杂草的防效分别为60.13%~86.13%,83.65%~84.35%。2年的数据显示处理组可以使作物产量增加6.12%,4.63%,纯收益分别提高了501.04,349.57元·hm^(-2)。人工除草的处理对杂草的防除效果显著优于除草剂的处理,但投入成本过高。生产中建议选用960 g·L^(-1)精异丙甲草胺EC播后芽前土壤封闭处理防治黄淮地区夏芝麻田杂草。In order to screen out a safe herbicide suitable for soil sealing of summer sesame field in Huanghuai area,field experiments were conducted in 2018 and 2019,respectively.The results showed that the broadleaf weeds and gramineous weeds in summer sesame field was decreased by 60.13%-86.13%and 83.65%-84.35%after soil sealing treatment(960 g·L^(-1)metolachlor EC 900 mL·hm^(-2)).The yield was increased by 6.12%and 4.63%compared with the control treatment in two years and the net income was 501.04 and 349.57 yuan·hm^(-2),respectively.The effect of artificial weeding was better than that of herbicide treatment,but the investment cost was too high.Thus,the 960 g·L^(-1) metolachlor EC was recommended to be used for soil seal treatment before germination to prevent weeds in summer sesame fields in Huanghuai area.
