摘要
提出以水型和起源土壤类型作为亚类的划分依据。土属必须考虑母质因素的影响。红壤性水稻土亚类的划分除了考虑指示性土层特性外,还必须考虑土体构型、物质淋淀以及土壤属性的剖面变化趋势。本文初步提出划分红壤性水稻土亚类的一系列指标。
It is suggested that water regime together with type of original soil be based for subgroup dividing,and the factor of parent material be considered in the family category.For identifying different subgroup,soil profile sturcture,type of leach-illuviated process and the change trend of genetic characteristics with the depth should be paid attention to,besides the properties of diagnostic horizon.A series of criteria for subgroup were also suggested in this paper.
