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．
Cultivation experiments were conducted to study the morphological distribution of zinc in red soils from four different parent materials in Hunan province. The results show that the residual zinc and iron oxide in the original soil account for more than 90%. After the soil added exogenous zinc, the absolute content of various forms of zinc increased, the relative content of zinc in addition to the exchange state and manganese oxide increased, the other forms of zinc decreased. The addition of lime and superphosphate in the soil to which exogenous zinc was added significantly reduced the exchangeable zinc content. After applying fresh pig manure and lignite, exchangeable zinc decreased, while organic zinc increased to varying degrees.
