摘　　要：采用田间试验研究了白肋烟品种达白1号采收方式和砍收时期对不同部位间烟叶生物碱含量及氮碱比差异的影响。结果表明,全整株砍收烟叶生物碱、总氮含量的部位间差异最小,其次为大半整株采收,摘叶采收的烟叶生物碱、总氮含量和氮碱比的部位间差异较大。砍收较早时,部位间生物碱含量差异小,随着砍收期的推迟,上部叶生物碱积累量的增加幅度大于下部叶,生物碱含量的部位间差异增大。Field experiments were conducted to investigate the effects of harvesting method and time on the differences in alkaloid content and nitrogen-nicotine ratio among cv.Dabei 1 cured leaves from different stalk positions.The results showed that the differences in alkaloid and nitrogen contents among stalk positions were smaller in cured leaves harvested by whole stalk cutting than those by stalk cutting and partial priming,while the differences in alkaloid and nitrogen contents and nitrogen-alkaloid ratio were the biggest by full priming.Early cutting resulted in smaller differences in alkaloid content,and with the delay of cutting time,the differences increased due to alkaloid accumulation in upper leaves greater than that in lower leaves.
