Abstract

选取云南曲靖烟区973份烤烟样本及其栽培地点的土壤样品, 研究了不同类型清香型烤烟的特征及土壤因素对烤烟清香型风格的影响。结果表明: 1)清香型特征明显的烤烟香气质较好, 香气量尚足, 杂气较轻, 余味尚舒适, 刺激性较弱, 浓度、劲头相对较小, 成团性、甜度、柔和性均高于清香型特征有和清香型特征弱的烤烟; 2)不同土壤类型烤烟清香型特征存在显著差异, 以红壤所对应的烤烟清香型特征最为突出, 其速效磷、速效钾含量相对较高, 清香型特征明显的烤烟样本比例达到76.33%; 3)清香型特征明显的烤烟所对应的植烟土壤pH适宜, 有机质、全氮、碱解氮含量相对较低, 而全磷、全钾、速效钾和有效铁含量显著高于清香型特征弱的烤烟所对应的植烟土壤; 4)对烤烟清香型风格与土壤因素进行灰色关联分析表明, 土壤全磷、全氮、有效铁、有效镁、速效钾、碱解氮含量对烤烟清香型风格的影响较大。
