摘 要:利用田间试验研究了高海拔地区(海拔1 400 m以上)烟草(Nicotiana tabacum L.)不同留叶数对烤烟产量、质量的影响。结果表明,在高海拔烟区,留叶数越少,越有利于烟草生长发育及上等烟比例的提高,留叶数18~20片的产量、产值最高,与留叶数22片相比,产量可提高7.6%~9.5%,产值可提高22.1%~24.4%。留叶18~20片的烤烟烟碱、总氮含量适宜,总糖、总钾含量较佳,其他化学成分协调。因此在高海拔烟区,烟草适宜的留叶数为18~20片。Field experiment was conducted at high altitude above 1 400 m to study the effects of different remained leaf number of tobacco (Nicotiana tabacum L.) on leaf yield and quality of flue-cured tobacco. The results showed that in high altitude area, less remained leaf number was good for tobacco growth and development, and could increase the high class leaf ratio. The remained leaf number was controlled between 18 and 20, reached the maximum tobacco yield and quality, improved yield by 7.6%-9.5% and production value by 22.1%-24.4%. Meanwhile, tobacco leaves had proper nicotine and total nitrogen content, appropriate content of total sugar, potassium and other chemical constituents under this condition. According to com- prehensive analysis, the proper remained leaf number of flue-cured tobacco was between 18 and 20 in high altitude area.
