摘要
采集湖南烟区上、中、下3个部位烤烟样本180份，分析了烤烟焦油量的生态地域差异和部位差异。结果表明：湖南烟区上、中、下3个部位烤烟焦油量均值分别为19．9、16．9和12．71mg／支，主要分布区间分别为17．8～20．8、13．4～16．0和10．2～14．0mg／支，烤烟下部叶焦油量变异系数相对较大；生态区域间烤烟焦油量差异显著，表现为湘西北烟区较高；地区间烤烟焦油量差异显著或极显著，表现为湘西州烤烟焦油量相对较高，永州市、长沙市烤烟焦油量相对较低；在生态区域分布上，烤烟上部叶焦油量存在从西北往东南方向逐渐降低、从西南往东北方向先升高后降低的趋势，烤烟中部叶焦油量存在从西北往东南方向先降低后升高、从西南往东北方向先升高后降低的趋势，烤烟下部叶焦油量存在从西北往东南方向先降低后升高、从西南往东北方向逐渐降低的趋势。
The tar deliveries of lower） grown in Hunan tobacco 180 flue-cured growing areas tobacco samples from 3 stalk positions （upper, middle and were analyzed. The results showed that： the means of tar deliveries of upper, middle and lower leaves were 19.9, 16.9 and 12.71 mg/cig. , respectively, whose main distributing ranges were 17. 8-20. 8, 13. 4-16. 0 and 10. 2-14. 0 mg/cig. , respectively. For same stalk position, the tar deliveries of leaves from Northwest Hunan were the highest, and the difference was significant between ecological areas ; the tar deliveries of leaves grown in Xiangxi was relatively higher, those in Yongzhou and Changsha were relatively lower, and the difference was significant or extremely significant between areas. The eeo-regionally tar deliveries of upper leaves declined gradually from northwest to southeast, and increased initially and then decreased gradually from southwest to northeast; for middle leaves, which declined initially and then increased from northwest to southeast, while from southwest to northeast were on the contrary; for lower leaves, which decreased initially and then increased from northwest to southeast, and declined from southwest to northeast.
