| 摘 要： | 以岷江冲积物、黄壤残积物发育成的水稻土为对照,研究了紫色砂岩泥岩母质发育成的紫色水稻土氧化铁的形态及其含量和转化。揭示了紫色水稻土具有无定形铁含量,铁活化度较高,氧化铁的转化作用较弱等独特的发生特性。

| Abstract: | In contrast to the paddy soils derived from the alluvium from the Minjiang River and yellow earth residual deposit,the contents and differentiation of iron oxides of purple paddy soils derived from purplish soil deposit were studied.The research results showed as follows:1.For purple paddy soils,the content of amor, iron oxide and activation degree of free iron oxide were higher,the content of free iron oxide,Feo-o/Feo ratio and Kh value (horizon rate of Feo-o/Feo ratio)were lower.2.The changes of iron oxides were weak,with a slight differentiation.3.The differentiation of iron oxides in the profiles was controlled by eluviation-illuviation of iron oxides and local differentiation of iron oxides. |
