  摘  要:为客观分析和评价广东烟区烤烟化学成分可用性,以2013—2017年度广东烟区8个主产县的C3F烟叶为材料,应用模糊数学方法、多元统计方法等构建烤烟化学成分评价体系,分析了广东烟区烤烟中部叶化学成分的年度、区域特征并进行了可用性评价。结果表明,近5年来,广东烟区烤烟中部叶总糖(25.09%)、还原糖(21.83%)、氯离子(0.25%)含量相对较低,糖碱比(8.52)和氮碱比(0.69)相对较小,烟叶化学成分可用性在“中等”及以上占85.00%;部分年度间、产区间烟叶的总植物碱、总氮、钾离子含量以及糖碱比、氮碱比存在显著性差异,但产区之间烟叶化学成分可用性无显著差异;广东烟区中部烟叶依化学成分可分为3类,分别相对集中于同一生态区域。

  中图分类号:TS41+1          文章编号:1007-5119(2019)02-0064-09      DOI:10.13496/j.issn.1007-5119.2019.02.010
  Abstract: In order to objectively analyze and evaluate the usability of flue-cured tobacco chemical constituents in the Guangdong tobacco-growing area, an evaluation system of chemical composition of flue-cured tobacco was constructed by adopting fuzzy mathematics, multiple statistics and others with C3F flue-cured tobacco samples collected from 8 major producing counties in the Guangdong tobacco-growing area from 2013 to 2017. The time and regional characteristics of chemical components in the leaves of flue-cured tobacco were analyzed, and the usability of tobacco chemical components was evaluated. The results showed that in the recent 5 years, the contents of total sugar (25.09%), reducing sugar (21.83%), chloride ion (0.25%), the sugar nicotine ratio (8.52) and nitrogen nicotine ratio (0.69) in middle leaves were relatively low. The chemical composition usability of tobacco leaves of “moderate” and above accounted for 85.00%. There were significant differences in total nicotine, total nitrogen, potassium ion content, sugar nicotine ratio and nitrogen nicotine ratio in tobacco leaves between years and the regions, but there was no significant difference in the usability of chemical components in tobacco leaves between producing areas. According to chemical composition, there are three types of flue-cured tobacco in the Guangdong tobacco-growing area, each of which is relatively concentrated in the same ecological area respectively.
  外觀质量评价,通过聚类分析将河南烟叶外观质量分为3类。马京民等[6]采用主成分分析和聚类分析方法,结合外观质量和化学成分指标,将河南省信阳烟区45个烤烟样品分为3个类别。张强等[7]通过集成简单相关、一元线性回归、典型相关分析3种数理统计方法,对5个烟叶常规烟气和20个主要化学成分的数据进行分析,筛选出总糖、总氮、氯、挥发碱、钾等11项指标建立云南烤烟主产区烟叶质量评价的指标体系。江春等[8]对2014年皖南地区6个日本成人电影区域所取的70个中上部烟叶样品进行了化学成分分析与感官质量评吸后得出皖南烟叶大部分化学成分含量适宜,浓香型风格突出的结论,提出生产中可通过适当降低糖含量、提高钾离子含量,控制杂气和刺激性来优化烟叶质量的建议。朱梅华等[9]研究了2012—2013年广西主要烟区的95个样品的主要化学成分和感官质量,指出生产中可通过控制糖含量、氮碱比及适当降低糖碱比来优化烟叶质量。齐永杰等[10]以桂阳县2012年、2013年和2014年烟叶样品为材料,应用模糊数学方法对其化学成分可用性进行了综合评价,得出烟叶化学成分可用性指数可以用于卷烟品牌对产区烟叶化学成分的适配度评价的结论。
