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。
Proposed to water and the origin of soil types as a subclass of the basis for the division. Soil must consider the influence of the parent material. In addition to considering the characteristics of indicator soil, the division of red soil paddy soil must also take into account the change of profile of soil structure, material deposition and soil properties. In this paper, a series of indexes for subdividing red soil paddy soil are proposed.
