摘　　要：为探究不同植烟区域烟叶中微量元素差异及其与外观质量指标之间的关系,采集了福建、贵州、河南、湖南、四川、云南6个省份共264个C3F等级初烤烟叶样品,分析了烟叶外观质量并测定了Mn、Fe、Cu、Zn、Ca、Mg等6种中微量元素的含量。结果表明,我国主要植烟区域烟叶中Mn、Fe、Cu、Zn、Ca、Mg 6种元素含量范围分别为14.24~452.10 mg/kg、46.62~613.98 mg/kg、1.13~72.79 mg/kg、6.32~123.09 mg/kg、6.14~48.44 g/kg和0.88~7.27 g/kg。烟叶中微量元素含量存在一定区域差异,河南产地烟叶Mn、Zn含量较低,Fe、Cu、Ca含量较高;福建产地规律与之相反;云南、贵州、四川3地烟叶中微量元素含量接近。Cu、Fe、Zn、Ca、Mg大多与外观质量间存在一定程度的负相关关系,Mn与外观质量之间存在一定程度的正相关关系;6种元素与外观质量灰色关联度排序为Cu>Zn>Fe>Ca>Mn>Mg;Cu、Zn对烟叶外观质量的影响较大。因此,烟叶生产过程中应注意Cu、Zn的合理施用,以提升烟叶外观品质。To investigate the difference of levels of medium to trace elements in tobacco leaves from different planting areas and their correlations with leaf appearance quality indexes,264 flue-cured tobacco leaf samples(C3F)were collected from six provinces including Fujian,Guizhou,Henan,Hunan,Sichuan and Yunnan.The appearance quality and the contents of Mn,Fe,Cu,Zn,Ca and Mg in tobacco leaves were analyzed.The results showed that the contents of Mn,Fe,Cu,Zn,Ca and Mg in tobacco leaves ranged from 14.24-452.10 mg/kg,46.62-613.98 mg/kg,1.13-72.79 mg/kg,6.32-123.09 mg/kg,6.14-48.44 g/kg and 0.88-7.27 g/kg,respectively.There were also significant regional differences in their contents.Mn and Zn contents in leaves from Henan were significantly lower,but the contents of Fe,Cu and Ca were higher;while Fujian’s leaf samples had an opposite trend.The contents of the six elements in tobacco leaves from Yunnan,Guizhou and Sichuan were similar.Cu,Fe,Zn,Ca and Mg contents were negatively correlated with most appearance quality indexes,while Mn was positively correlated with these indexes.The grey correlation degree of the six elements with the appearance quality was Cu>Zn>Fe>Ca>Mn>Mg.Cu and Zn had great influences on the appearance quality of tobacco leaves.Therefore,Cu and Zn should be reasonably applied in order to improve the quality of tobacco leaves.
