本文对贵州中部和东部地区不同母质、不同发育程度以及不同肥力的12个黄泥类水稻土剖面和3个白鳝泥土样(耕层)做了各种形态的铁锰的测定,发现不同母质发育的黄泥类水稻土铁、锰含量差异很大。根据铁、钙含量和形态,作者认为广泛分布于贵州高原的第四纪红色粘土大致可区分为粘Ⅰ和粘Ⅱ两种,二者不仅在地理分布上有差别,而且铁、锰含量也有显著差异。这种区分在土壤发生分类及利用改良上均有一定意义。

In this paper, the determination of iron and manganese in 12 forms of yellow muddy soil profile and three soil samples of paddy soil (plow layer) with different parent materials, different development degrees and different fertility in central and eastern Guizhou Province was carried out. It was found that different parent materials Of yellow muddy paddy soil iron, manganese content varies widely. According to iron, calcium content and morphology, the authors believe that the Quaternary red clay widely distributed in the Guizhou Plateau can be roughly divided into sticky Ⅰ and sticky Ⅱ, the difference between the two is not only geographical distribution, but also significant iron and manganese content difference. This distinction in the occurrence of soil classification and utilization are of some significance.
