| 中文摘要: |
| 为提高江西烟叶工业可用性，以烤烟品种云烟87 为材料，采用大田试验研究了不适用下部烟
叶摘除法对江西烤烟不同叶位烟叶叶面积、单叶重及烤后烟叶等级结构、经济性状、感官质量的影响。结果
表明，打顶后1 d 摘除下部叶，第10 叶位（中部叶）和第16 叶位（上部叶）烟叶的叶面积、单叶重及烤后
烟叶的产量、产值和上等烟比例均高于其他摘叶时间。同一摘叶时间下，摘除5 片下部叶时烟株叶片单叶
重、上等烟比例均高于摘除2 片叶处理，上部叶比例增加1.8%～3.2%。随着摘除下部叶时间推迟，上部叶
比例降低，而中部叶和下部叶比例增加。打顶后1 d 摘除2 片下部叶时，C3F 和B2F 等级烟叶的评吸质量最
好。综合烤烟生长及产质量性状，打顶后1 d 摘除2 片下部叶适宜作为生产中优化烟叶结构的依据。 |
| 英文摘要: |
| To improve the industrial usability of jiangxi tobacco leaf，the flue-cured tobacco variety Yunyan
87 was selected to study the effects of different methods of removing lower leaves on leaf area，leaf weight，
leaves structure，economic characters and smoking quality of flue-cured tobacco. The results showed that removing
lower leaves at 1 day after topping could obtain higher leaf area，leaf weight，yield，output value and the ratio of 10th
and 16th leaves than other treatments. Under the same time of removing lower leaves，leaf weight and high-quality
tobacco ratiowere higher under the treatment of removing five leaves than those under the treatment of removing
two leaves，and the proportion of upper leaves increased 1.8%-3.2%. With the delay of removing lower leaves，
the rates of middle and lower leaves increased and the rates of upper leaves decreased . Sensory quality of the leaves
of C3F and B2F was the best under the treatment of removing two leaves after topping 1d. Therefore，we suggested
removing two leaves at 1day after topping was the best option for optimizing configuration of tobacco leaves in Jiangxi. |
