摘要
土壤条件对烟叶香型风格的彰显程度有着重要影响。土系是系统分类中最低级的基层分类单元,也是和生产应用最紧密的单元。湖南是我国主要烤烟产区之一,本研究以湘南的江华和桂阳、湘西靖州、凤凰和桑植作为湖南的代表,通过35个典型优质烟田的土壤调查尝试建立相应的土系。结果表明:①调查的湘南和湘西35个优质烟田土壤系统分类类型涉及到人为土、富铁土、淋溶土和雏形土4个土纲和相应的4个亚纲、9个土类、14个亚类,可以划分为17个土族和27个土系。②烤烟为浓香型风格的湘南烟田土壤以具有石灰性的复钙型水耕人为土为主,烤烟为浓偏中间香型风格的湘西烟田土壤没有石灰性,可以初步认为土壤的石灰性或碳酸钙以及有机质含量是形成烤烟浓香型风格的重要因素。
Soil plays an important role in highlighting the aroma style of tobacco leaves. Soil series is lowest classification unit of soil taxonomy and is the holographic ID card of soil. Hunan is one of the main tobacco-planting provinces, this paper took Jianghua and Guiyang in southern Hunan （region of full-aroma type of flue-cured tobacco） and Jinzhou, Fenghuang and Shangzhi in westem Hunan （region of middle-scent type of flue-cured tobacco） as the study regions, selected totally 35 typical tobacco fields which could grow the tobacco leaves of the highest-quality and tried to establish preliminarily the relevant soil series. The results showed that： 1） the 35 typical tobacco field soils could be classified into 4 orders （Anthrosols, Ferrosols, Argosols and Cambosols）, 4 suborders, 9 groups, 14 subgroups, 17 families and 27 series. 2） Soils of southern Hunan usually showed calcareous property while soils of western Hunan didn＇t show calcareous property, which suggested calcareous property of soil may be one of the important factors in forming the full-aroma type of flue-cured tobacco.
