- 摘要:
- 为促进大豆田实际生产中茎叶除草剂的合理选择与应用，选择9种茎叶除草剂采用随机区组试验设计方法，进行田间药效试验。结果表明，施药后30 d的鲜重防效结果表现为240 g·L-1烯草酮乳油、108 g·L-1高效氟吡甲禾灵乳油对禾本科稗草防效在90%以上，250 g·L-1氟磺胺草醚水剂、480 g·L-1灭草松可溶液剂、84%氯酯磺草胺水分散粒剂对阔叶杂草防效在80%以上，480 g·L-1异噁草松乳油、自混对一年生杂草总草防效在80%以上，复配药剂35%松·喹·氟磺胺乳油和37%氟·松·烯草酮可分散油悬浮剂对一年生杂草总草防效在90%以上；施药后14 d作物安全性结果，480 g·L-1异噁草松乳油、自混及两种复配药剂均对大豆产生一定药害；测产结果，各处理组与空白对照组相比增产明显，增产率为37.27%~66.31%。综上，不同除草剂的杀草谱不同、对大豆的安全性也有一定差异，两种复配药剂总草防效优异，虽对大豆产生一定药害，但与人工处理组相比产量无明显差异。
