摘要
通过培养试验研究了湖南４种不同母质发育的红壤锌的形态分布．结果表明：原始土壤中残留态锌和氧化铁态锌占９０％以上．土壤加入外源锌后，各种形态锌的绝对含量均提高，相对含量除交换态和氧化锰态锌提高外，其它形态锌有所下降．在加入外源锌的土壤中施入石灰和过磷酸钙后，能显著降低交换态锌含量．施入新鲜猪粪和褐煤后，交换态锌有所降低，而有机态锌有不同程度提高．
The distribution of zinc fractionation in the soils from 4 kinds of different parent materials were studied by incubation experiment.The results showed that the amount of the residual Zn and iron oxides Zn were over 90% of the total,the absolute content of various forms of Zn greatly increased by adding Zn to the soil and the mophological distribution of Zn in soils,which had been added with additional Zn soils,such as lime,superphosphate,fresh hog manure and humus coal,significantly decreased the exchangeable Zn.
