In order to explore the suitable range of single leaf weight for tobacco in the upper part of Zhangjiajie City, taking the main cultivar K326 as the research object, different single leaf weight intervals were set, the relationship between single leaf weight and the main physical characteristics, sensory quality of tobacco was analyzed,the suitable single leaf weight was determined.The results showed that combining the effects of single leaf weight on the physical properties and sensory quality of tobacco leaves,the performance of tobacco leaves with the single leaf weight of 8-10,>10-12,>12-14 g,respectively at Gaofeng test site was better. The upper leaves with the single leaf weight of 8-10 and >10-12 g at Jiangya test site had better quality and higher availability. According to the correlation between leaf length and single leaf weight, the suitable leaf length for Zhangjiajie tobacco area could be obtained,the proportion of upper leaves with the leaf length of 51.25-67.82 cm at Gaofeng test site and the proportion of upper leaves with the leaf length of 51.21-63.13 cm at Jiangya test site could be used as the techni-cal control targets.
