本文讨论了黄潮土上发育的水稻土的发生特点。对水稻土与起源土壤共六个主要剖面进行了研究。结果表明:(1)游离铁含量在1—2％的范围;(2)起源土壤(黄潮土)中无定形铁含量是低的,而水稻土耕层含量高;(3)铁的活化是水稻土形成的中心过程。这有助于徐淮地区水稻土发生分类的研究。
This paper discusses the occurrence characteristics of paddy soil developed on yellow soil. A total of six major sections of paddy soil and its origin soil were studied. The results showed that: (1) the content of free iron was in the range of 1-2%; (2) the content of amorphous iron in origin soil (yellow soil) was low while that in paddy soil was high; (3) The formation of the earth’s central process. This is helpful for the classification of paddy soils in Xuhuai area.
