摘要
为了明确陕西省烟叶主产区土壤类型归属,选取了陕西省烟叶适宜种植区中洛南县、陇县、旬阳县3个典型剖面,分别进行了野外观察描述土壤性状和室内测试土壤剖面各层次的基本理化性质。在研究了各取样地土壤形成条件和特点的基础上,按照《中国土壤系统分类检索(第3版)》,鉴定了诊断层和诊断特性,明确了供试土壤剖面在中国土壤系统分类中的归属。检索结果表明,陕西洛南、陇县、旬阳3个烟叶种植基地土壤分别为普通铁质湿润淋溶土、普通钙积干润均腐土、普通简育湿润淋溶土。同时与中国土壤发生分类进行了比较,以便于今后陕西省烟叶种植区对土壤系统分类的推广及利用,并为陕西省烟叶种植基地土壤规划利用和国际间土壤学术交流提供科学依据。
In order to define soil type in the main tobacco producing areas of Shaanxi Province, this study selected three typical soil profiles in the suitable planting areas（Luonan, Longxian and Xunyang Counties） and separately carried out field observation and indoor test to collect basic soil physical and chemical properties in each horizon. Based on the study of the formation conditions and characteristics of soil samples, the diagnostic horizon and diagnostic characteristics of each soil sample were characterized, as well as the identification in Chinese soil taxonomy system, according to the Chinese Soil Taxonomy（3rd edition）. Results show that the identifications of the profiles are typic Ferri-udic Argosols in Luonan County, typic Calci-ustic Isohumosols in Longxian County and typic Hapli-udic Argosols in Xunyang County. In order to facilitate the extension and utilization of soil taxonomy system in the Shaanxi tobacco planting areas and provide scientific basis for soil planning in the Shaanxi tobacco planting base and international academic communication, com- parison between Chinese soil taxonomy and Chinese genetic soil classification was made.
