摘　　要：为研究贵州不同生态区烟叶的特色,挖掘贵州烟叶的生态优势,选择黔北道真县、黔东南天柱县、黔中贵定县、黔西南兴义市和黔西北威宁县5个典型的烟叶生态区,在只施有机肥、一垄双行烟,密度为1 482株/667m2的栽培模式下,研究贵州不同生态区烟叶的品质特征及致香物质。结果表明,不同生态区烟叶产量、单叶重和单位叶面积重均低于常规生产烟叶;烟碱含量相对偏低,糖含量较高,其他指标较常规生产烟叶稍有下降,但总体成分协调,糖/碱高;烟叶烟气幽雅,愉悦感增强,香气丰富,甜润明显;不同生态区致香物质差异明显,体现了地域特色。Yunyan 85,a flue-cured tobacco variety,was planted under 1482 plants/667m2 density and applying organic manure in 5 typical ecological areas to study flue-cured tobacco quality and aroma components of different ecological areas for excavating the ecological advantage of flue-cured tobacco in Guizhou.The results showed that the flue-cured tobacco yield,single leaf weight,unit leaf area weight of Yunyan 85 planted under 1482 plants/667m2 density and applying organic manure in 5 typical ecological areas were all lower than those planted under the conventional cultivation pattern,the nicotine content of flue-cured tobacco applied with organic manure was relatively lower,its sugar content was relatively high and other quality indexes of flue-cured tobacco slightly decreased compared with those under the conventional cultivation pattern.In general,the flue-cured tobacco leaf has the characteristics of good harmoniousness,high sugar/nicotine ratio,elegant gas,intensified pleasure,abundant aroma and obvious sweet.There is obvious difference in aroma components among 5 different ecological areas,which reflects regional characteristics.
