采收方式对烤烟上部叶产质量的影响

目的]为进一步改善上部烟叶质量,提高上部烟叶在高端卷烟品牌中的使用率。方法]通过大田试验,研究了不同采收方式对顶6片烟叶叶绿素含量、含水率及烤后烟叶的外观质量、化学成分和感官评吸质量的影响。结果]顶6片叶一次性采收,烟叶外观质量、中等烟比例和感官评吸效果较分次采收有明显提高,内在化学成分更趋于协调;采收时烟叶叶绿素含量较分次采收有所下降,且烟叶部位越高,下降幅度越大;上等烟比例、产量较分次采收有所下降;采收方式对采收后鲜烟叶含水率及烟叶均价影响不大。结论]顶6片烟叶一次采收能提高上部烟叶质量,但经济效益略有下降。

Effect of Harvesting Way on Quality and Yield of Upper Leaf of Flue-cured Tobacco

Objective] In order to improve the quality of upper leaf,so as to increase the utilization rate of upper leaf in the high-end cigarette brand.Method] Field experiment was conducted to investigate the effects of harvesting way on chlorophyll content,moisture content of fresh tobacco,exterior quality,contents of chemical components,sensory quality.Result] The results showed that compared with two times harvested,the exterior quality,sensory quality and the proportion of the middle grades leaves increased of top six leaves harvesting one time,and the chemical compositions were coordinated;The chlorophyll contents decreased compared with two times harvested,and the chlorophyll contents would decreased more with the increasing of the part of flue-cured tobacco leaf;The finest grades leaves and the yield decreased compared with two times harvested;The harvesting way had little or no effect on moisture content of fresh tobacco and average value.Conclusion] The way of top six leaves harvested one time can increase the quality of upper leaf,whereas,the economic benefits declined.
