烟腋芽不仅消耗叶片的养分,而且影响烟叶的质量。传统的方法是人工摘除。人工摘除腋芽,不仅损伤叶片,降低烟叶等级,而且容易带进花叶病等传染毒菌。笔者在与老烟农交谈中,发现用莱油能抑制烟腋芽再生长,且省工节时。具体方法是:在烟株打顶后5～6天,用一小瓶装菜油若干(每667平方米约200克);用一支毛笔抹去烟腋芽,然后蘸上菜油涂在腋芽生长点 Smoke axillary buds not only consume nutrients, but also affect the quality of tobacco. The traditional method is manual removal. Artificial removal of axillary buds, not only damage leaves, reduce the leaf level, but also easy to bring mosaic gerbils and other infectious germs. In conversation with the old tobacco farmers, the author found that using rapeseed oil can inhibit the growth of smoke axillary buds and save time at work. The specific method is: 5 to 6 days after the tobacco plant topped with a small bottle of vegetable oil number (about 66 grams per 667 square meters); with a brush erased smoke axillary buds, and then dipped in vegetable oil coated axillary bud growth point
