摘　　要：通过对清香型5个亚区不同成熟度档次烟叶成熟茎叶角度检测分析,发现随着清香型亚区海拔的升高,茎叶角度整体呈增大的趋势,增大顺序为闽西北丘陵山地清甜区、滇南山地谷地清甜区、滇北川西南高原河谷清甜区、滇中高原平坝清甜区、滇东北黔西乌蒙山地清甜区。不同成熟度档次烟叶,随着烟叶成熟度的提升,茎叶角度呈增大的趋势,即未熟烟叶>初熟烟叶>适熟烟叶>过熟烟叶;适熟烟叶茎叶角度为40~50°。By analyed the angle of mature leaves and stems of 5 sub regions of the ecological region of planting sweet flue-cured tobacco with different maturity grades, the results showed that the angle of stem and leaf increased as the altitude increased. In descending order,regions are the hilly areas of the northwest of Fujian Province, the mountain and valley areas of the north of Yunnan Province, the river valley in the southwest plateau of Beichuan of Yunnan Province, Pingba in Yunnan Plateau, Wumeng Mountain between of the northeast of Yunnan Province and the west of Guizhou Province. The angle of stem and leaf was increased by the different maturity grades of tobacco leaf maturity upgraded, The order of the angle was the leaves of immatured the leaves of prime 〉the leaves of properthe leavews of overmatured; ripe tobacco leaves at 40-50 degrees angle between stem and leaf.
