| 摘 要： | 目的]研究几种水稻田除草剂对烟叶生长的影响。方法]于烟株团棵期,用4种水稻田除草剂对植烟垄土喷雾除草1次,选取有代表性的5株烟株作为定点株,分别于施药后5、15、30d调查叶宽抑制情况,并观察记载药害情况。结果]50%二氯喹啉酸WP对烟叶生长抑制作用最为明显,施药后15、30d,该药3种浓度处理对倒数第2、5片叶叶宽抑制率超过40%,药害程度＂＋＋＋＋＂（严重）,后期药害基本未能缓解;30%苄.丁WP、5.8%苄嘧磺隆.6.2%乙草胺WP、56%2甲4氯钠SP3种药剂对烟叶生长有一定的抑制作用,但叶宽抑制率均低于20%,后期药害均有不同程度缓解。结论]水稻田除草剂二氯喹啉酸对烟叶生长有明显的抑制作用,其药害症状与永州市烟田烟叶畸形生长症状基本相同。 |

| Abstract: | Objective] The aim was to study the effects of several kinds of herbicide in paddy on flue-cured tobacco leaf growth.Method] Flue cured tobacco fields were weeded with 4 kinds of herbicide in paddy at the Rosette Stage.5 representative tobacco strains were chosen as the fixed strains,and their leaf width inhibiting rates were investigated respectively 5,15 and 30 days after chemical application,and the phytotoxicity to tobacco strains was observed.Result] 50% Quinclorac showed the most inhibiting effects... |
