| 【目的】分析评价云南新烟区烟叶的主要化学成分特征，为掌握当地烟叶质量特点及提高工业可
用性提供参考。【方法】采集 2011—2018 年文山广南、普洱景东和临沧双江 3 个县区上、中、下 3 个部位烟叶
B2F、C3F、X2F 样品 288 份，测定烟叶中的主要化学成分，并对其与卷烟质量的关系进行分析。【结果】2011—
2018 年文山广南、普洱景东和临沧双江 3 个县区上、中、下 3 个部位烟叶的氯含量总体偏低，有 41.92% 的中部
样品还原糖含量超过 26%，有 33.33% 的上部样品烟碱含量超过 3.5%，中部烟叶样品还原糖含量偏高、上部烟叶
烟碱含量偏高是影响新烟区 3 个植烟县化学成分协调性的主要因素。2011—2018 年 3 个植烟县烟叶的钾含量和氯
含量相对稳定。2013 年以来，中、上部烟叶总糖和还原糖含量主要表现为上升趋势，增幅最大达到 16.02%，烟
碱和总氮含量则总体呈下降趋势，降幅最大达到 22.07%。灰色关联分析结果表明，在试验范围内对烟叶感官评
吸质量总分影响最大的化学成分指标为总氮和还原糖含量 。【结论】云南新烟区 3 个植烟县烟叶主要化学成分特
征差异明显，在双江地区控制烟叶还原糖含量、适当提高总氮含量有助于提高烟叶品质，在广南地区则应从控制
烟叶总氮和烟碱含量方面改善烟叶化学成分协调性。 |

| 【Objective】In order to understand the quality characteristics of tobacco leaves from new tobacco growing
areas in Yunnan and improve the industrial usability of tobacco leaves, the characteristics of main chemical components
in flue-cured tobacco leaves were analyzed.【Method】288 samples of the upper, middle and lower tobacco leaves (B2F,
C3F, X2F) during 2011-2018 were collected from Guangnan, Jingdong and Shuangjiang. The main chemical components in
tobacco leaves were determined and their relationships with cigarette smoking quality were studied.【Result】The chlorine
contents in all the upper, middle and lower tobacco leaves during 2011-2018 collected from Guangnan, Jingdong and
Shuangjiang were relatively low in general. The reducing sugar contents in 41.92% of the middle leaves were higher than
26%, and the nicotine contents in 33.33% of the upper leaves were higher than 3.5%. Higher nicotine contents in the upper
leaves and higher reducing sugar contents in the middle leaves were the main factors influencing the chemical componentcoordination of tobacco leaves from the 3 tobacco planting counties of new tobacco growing areas. The contents of potassium and
chlorine in tobacco leaves during 2011-2018 were relatively stable in the 3 tobacco planting counties. However, the contents
total sugar of reducing sugar in middle and upper leaves showed an increasing trend since 2013, and the biggest increase was
up to 16.02%. The contents of nicotine and total nitrogen showed a downward trend since 2013, and the biggest decrease was
22.07%. The grey correlation analysis indicated that the contents of total nitrogen and reducing sugar were the main chemical
component indicators influencing the total scores of smoking quality.【Conclusion】There were significant differences in the
characteristics of main chemical components in tobacco leaves from 3 tobacco planting areas of Yunnan. It is recommended that
total nitrogen contents of tobacco leaves in Shuangjiang should be appropriately raised and reducing sugar contents be reduced,
while the coordination of chemical components of tobacco leaves in Guangnan can be improved by controlling the contents
nitrogen and nicotine . |
