| Abstract: |
| 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. |
