| 摘 要： | 为探索在高寒地区春油菜田防除禾本科杂草技术，并筛选油菜田除草剂新品种，于2006年引进12%烯草酮乳油，以12.8%高效盖草能乳油为对照进行了对比试验.结果表明：12%烯草酮乳油对春油菜田禾本科杂草防除效果显著，适宜用量为72-108 g/hm^2，除草效果达94.4%-98.61%，对油菜安全，油菜增产达20.29%-22.73%.适宜施药时期为靶标杂草基本出齐后至分蘖前（即禾本科杂草长至2-5叶期）.

| Abstract: | To screen effective herbicide for preventing and eliminating grass family weeds in spring rape field, a comparative study was conducted with introduced clethodim EC and haloxfop-R-methyl. The resuits indicated that 12% clethodim EC had better weed control effect than 12.8% haloxfop-R-methyl. The proper dose was within the range of 72- 108 g/hm^2 and weed mortality was from 94.40% to 98.61%. Compared with control, rape yield increased 20.29 % - 22.73 % after application. The proper period of spraying was when weed had 2- 5 leaves. |
