摘要
油茶是我国特有的食用油料树种.油茶分布广,面积达6000多万亩.中国油茶林地土壤类型的划分,为油茶林地选择及土壤管理提供重要的科学依据。本文应用土壤发生学分类方法,建立了土类、亚类、土属、类型四级分类系统.将中国油茶林地的土壤划分为4个土类、5个亚类、28个土属、107个类型。在此基础上,以每个发生类型作为样本,A层和B层有机质、全氨、全磷、全钾含量等8项指标作为变量,用系统聚类方法对4个亚类分别进行聚类,归并为13个肥力类型.
A classification with four categories, i.e., soil group, soil subgroup, soil genus, and soil type, was established, using the theory of pedogenesis. Accordingly, the soil of oiltea camellia plantations in China is classed into 4 groups, 5 subgroups, 28 genera and 107 types. On this basis, 13 fertility degrees were determined with system cluste r analysis.
