对湖南省 1 0个有代表性红壤样品进行化学分组测定 .结果表明 ,土壤有机态、无定形铁态、晶形铁态和残留态铜分别占全铜量的 1 5 2 %、1 1 7%、1 7 2 %和 5 6 0 % .红壤性水稻土有机态和无定形铁态铜 ,明显高于耕型红壤 ,而晶形态、残留态铜则相反 ,供试土壤有效铜含量与土壤有机态铜和无定形铁态铜含量呈极显著性正相关
The results showed that soil organic, amorphous iron, crystalline iron and residual copper accounted for 15.2% and 11.7% of the total copper, respectively, , 17.2% and 56.0% respectively.The content of organic and amorphous iron-copper in red paddy soil was significantly higher than that in red soil, while the crystal form and residual copper were the opposite. State copper and amorphous iron state copper content was extremely significant positive correlation
