| 摘 要： | 选用仲丁灵、金都尔和使它隆3种除草剂,研究不同施药浓度对燕麦田杂草的防效及燕麦种子产量的影响。结果表明:供试的3种类型除草剂不同浓度对燕麦田杂草均有较好的防效,并且安全性好,无药害发生。48%仲丁灵,96%金都尔,20%使它隆在燕麦田的最佳施用浓度分别为5 625,1 350和750mL/hm2,30d株防效分别为79.7%,84.4%和87.8%,增产率分别为25.8%,31.8%和39.2%。

| Abstract: | The effect of 3 different herbicides(butralin,s-metolachlor and starane) on weeds control and oat seeds yield was studied by measuring the weed height,coverage,abundance and fresh weight.The result indicated that 3 herbicides were effective in oat field and no damage was observed.The best dosage for 48% butralin,96% s-metolachlor and 20% starane were 5625 ml/ha,1 350 ml/ha and 750 ml/ha,respectively,and their 30 d plant efficacy were 79.7%,84.4% and 87.8%,with 25.8%,31.8% and 39.2% oat grain increment. |
