Eliminates the bud topass damps the bud effect tobebest. InShi Yaohou 20days, each Shi Yao processes damps the bud effect above 90%. 30days later, eliminates the bud topass damps the bud effect %, passed pared tothe vegetable grass tobehigher than %, but the smoke processed only suppresses the effect for -%. Shi Yao processes the economic character tosurpass the manual handling obviously, has the remarkable difference. The position difference is small. The quality synthetic evaluation, passes the performance bythe vegetable grass tobemost superior. key word: o Damps the bud rate toproduce the quality position 关键词:烟草抑芽率产质量化学成份烟草抑芽剂自 20世纪 40年代开始发现应用以来,先后出现十几种烟草抑芽剂,对烟叶的生产起到了极大的促进作用[1]。打顶抹杈是烟草生产的一
