Effects on different methods of removing lower leaves on leaves configuration and economic characteristics of flue-cured tobacco in Jiangxi
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 6
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."
