| 摘 要： | 本文研究了我国部分自然土壤中氧化铁、氧化锰及有机质三种组分对原有土壤中锌的富集能力。并比较了不同土壤类型中各组分对锌的富集能力,探讨了土壤环境条件主要为pH对组分富集能力的影响。结果表明,土壤中这三种组分其单位含量对锌的富集能力为:氧化锰>氧化铁>有机质;三:种组分对锌的富集能力在土壤间的变化以氧化铁最为明显,其顺序为石灰性土壤>中性土壤>酸性土壤;土壤pH对土壤氧化铁富集锌能力的影响也很明显。氧化铁对锌的富集分配比例为:酸性土壤<5,中性土壤5—15,石灰性土壤≥15,各土壤组分对锌的富集容量次序为:氧化铁>有机质>氧化锰,氧化铁中,晶形铁>无定形铁。

| Abstract: | The enrichment capability of native zinc by iron oxide, manganese oxide and organie matter in 18 soils of the eastern China were studied with the sequential extraction fractionation procedure. Soils used incaude 5 acid soils, 5 neutral soils and 8 calcareous soils which are derived from 11 kinds of parent materials from south to north in China. The enrichment capability of native zinc by per unit soil components is different from enrichment capacity of soil components, and a comparative study of them were conducted. |
