云南省不同烟区K326烟叶的常规化学成分比较

摘要

[目的]比较云南不同烟区K326 B2F烟叶常规化学成分的地区差异性.[方法]常规化学成分采用连续流动分析仪检测,并利用SPSS 17.0统计软件包进行数据的统计分析和方差分析.[结果]不同地区K326的各项常规化学成分指标大多存在显著差异,其中总糖、还原糖和烟碱差异达到了极显著水平；钾和总氮差异达到了显著水平,氯则无显著差异.玉溪地区的K326B2F烟叶大部分常规化学成分与曲靖、大理和楚雄间均存在显著差异.滇东、滇中和滇西3个烟区的总糖、还原糖和烟碱含量的差异明显；而同属滇西的楚雄和大理间常规化学成分含量差异并不明显,这说明云南省不同大区域间生态环境的差异对烟叶的影响较大.[结论]揭示了云南省K326初烤烟叶常规化学成分特性的区域特征,为卷烟配方和特色优质烟叶的生产提供了参考依据.%[Objective] To compare the regional differences of the conventional chemical compositions in the K326 B2F tobacco from different tobacco-planting areas of Yunnan Province. [Method] Continuous flow analyzer was used to detect the conventional chemical compositions, and SPSS 17.0 statistical package was used to conduct data statistical analysis and variance analysis. [Result] Significant differences were existed among most of the indicators for conventional chemical compositions of K326 tobacco in different areas: the differences of total sugar, reducing sugar and nicotine reached a high significant level; potassium ion and total nitrogen differences reached a significant level, while there was no significant difference in chlorine ion. Most of the conventional chemical compositions in K326 B2F tabacco planted in Yuxi region and those planted in Qujing, Dali and Chuxiong were significantly different. The total sugar, reducing sugar and nicotine contents of tobacco planted in eastern Yunnan, central Yunnan and western Yunnan were significantly different; while the conventional chemical compositions contents in the tobacco planted in Chuxiong and Dali, which all belong to western Yunnan, showed no obvious significant difference, indicating different ecological environments in large area had a great impact on the tobacco of Yunnan Province. [Conclusion] It revealed the regional characteristics of the conventional chemical compositions in K326 flue-cured tobacco leaves from Yunnan Province, providing references for the cigarette blending and production of high-quality tobacco with characteristics.
