The Analysis of Single-leaf Weight, Appearance between Flue-cured Tobacco Leaf Position on the Stem in Lijiang
摘要
Abstract
In order to identify changes rule between flue-cured tobacco leaves positions, reducing the quality difference between the parts on the stem and rational utilization of tobacco leaf resources. Single-leaf weight and appearance of tobacco leaves in different positions analysis of 831 flue-cured tobacco samples from 37 sampling points in Lijiang area was conducted. The results show that; (1) Single-leaf weight of flue-cured tobacco in Lijiang was slightly higher. Leaf position 1 was the lightest with the weight of 7. 99 g and leaf position 16 was the heaviest with the weight of 13. 54 g. (2) From the leaf position classification results, middle leaves from the 5th to 15th leaf, all 9~11 leaves for the middle leaves groups. The lower middle leaf from 5~8 was to transition, all 12~15 leaves were a transition from the central to the upper. (3) The top quality tobacco starts to emerge in leaf position 5. The ratio of middle and upper class tobacco does not changed much from leaf position 7 to 12 and remains mostly at 80% . The ratio of middle and upper class tobacco becomes smaller and smaller from leaf position 13 to 18. There will be no top quality tobacco from leaf position 19.关键词
