烤烟烟叶化学成分与产区关系的聚类分析研究

Cluster Analysis on Relationship between Tobacco Growth Region and Chemical Compositions of Flue-cured Tobacco Leaves

摘要

摘要: 烟草质量与产区生态条件关系密切，同一产区常因生态条件的差异而造成烟叶质量的差异。烟叶收购、调拨以地市或县为单位，常造成质量差异大的烟叶采购到一起而影响烟叶的合理利用。同产区、同部位烟叶用化学成分聚类，可有效地将不同生态差异的烟叶进行分类。采用聚类分析方法对百色7个县97个C3F烤烟烟叶样品化学成分进行分区分类，为烟叶的合理利用、生产技术改进提高、产区定向栽培技术配套提供依据。试验结果表明，百色烟区可分为3个区，Ⅰ区包括隆林县、西林县和田林县；Ⅱ区包括乐业县、凌云县和德保兴旺、抚平、敬德等部分乡镇；Ⅲ区包括靖西县大部和德保县朴圩、都安、录峒、东陵、那甲等部分乡镇。3个区烟叶质量特色明显，且从外观质量、化学成分、感官质量对其烟叶质量进行了综合评价分析。

Abstract: Cluster analysis was employed on the chemical compositions of 97 flue-cured tobacco leaf samples (C3F) from seven counties of Baise, Guangxi to enhance tobacco leaf utilization, tobacco production technology and related cultivation management in different regions. Results showed that three regions could be divided in Baise. The first included Longlin, Xilin and Tianlin, and the second included Leye, Lingyun and several towns of Debao, such as Xingwang, Wuping, and Jingde etc. The third included most parts of Jingxi and some towns of Debao, such as: Puxu, Duan, Lutong, Dongling, Najia, etc. The flue-cured tobacco leaves in the three parts exhibited evident quality characteristics including appearance quality, chemical composition and sensory quality.
