摘　　要：为开发环境友好型的抑芽剂,以打顶不抹杈为阴性对照,以1%除芽通为阳性对照,对不同浓度菜籽油抑芽效果做了比较研究。结果表明:不同浓度菜籽油抑芽处理后,顶部第1片叶增加的叶面积在190.31～563.41 cm2,顶部第2片叶增加的叶面积在110.01～297.75 cm2,除6.7%浓度的菜籽油外,各处理对顶部叶叶面积的增加量与阳性对照无明显差异,但均显著高于阴性对照。不同浓度菜籽油在烟杈鲜重、抑芽率、抑芽效果等方面和阳性对照无显著差异,但均显著高于阴性对照。其中,10%菜籽油浓度腋芽处理成本和除芽通的相近,其烟杈鲜重为523.2 g、抑芽效果为86.8%、抑芽率为75.8%,显著高于阴性对照,可推荐在生产上使用。For earth-friendly tobacco leaf production practices, field trials on the effects of rapeseed oil for sucker control, which using a treatment of toping without sucker removing as negative control, a treatment of suckercide （Chuyatong） as positive control, was conducted. Compared to negative and positive controls, the first leaf area on the top was increased from 190.31 cm2 to 563.41cm2 treated by different rapeseed oil concentration, and the second one was increased from l l0.01cm2 to 297.75 cm2 different concentration of rapeseed oil, the other concentration rapeseed oil Suckercides processing. Despite of 6.7% rapeseed oil, no significant difference in increasing leaf area was observed for the multiple concentration rapeseed oil treatment compared to positive control. While there observed a significant difference in increasing top leaves area compared to negative control. Compared to positive control, no significant difference in fresh weight of axillary bud, sucker control rate, the sprout inhibition effect were observed, however, there observed significant differences in fresh weight of axillary bud, sucker control rate, the sprout inhibition effect when compared to negative control. For cost saving, 10% rapeseed oil treatment had a similar effect of sucker control with Chuyatong, it pitchfork fresh weight was 523.2g, the sprout inhibition effect was 86.8% and the suckercides rate was 75.8%, there were significant higher than the negative control, it could be recommended for use in the leaf production.
