[目的]研究无机钠盐对土壤中各种形态锌含量的影响。[方法]用Tessier连续提取法进行试验，研究了不同种类、不同浓度的无机钠盐对不同形态的锌离子浓度的影响。[结果]向土壤中加入不同的无机钠盐对于锌的存在形态产生的影响不同。对于可交换态锌，土壤中加入Na2CO3和Na2SO4使其含量减少，加入NaCl使其含量增加；对于碳酸盐结合态锌，NaCl和Na2SO4使其含量增加，而Na2CO4则使其含量减少，该形态锌的含量受Na2SO4影响较大；对于锌的铁锰氧化态、有机态和残余态，加入NaCl和Na2SO4后，其含量均减少，且加入钠盐浓度越大减少越明显，而加入Na2CO，则使铁锰氧化态的含量减少，使有机态和残余态的含量出现不同变化——低浓度使两者含量增加，高浓度使两者含量降低。【结论】该研究为不同地区土壤重金属离子含量的测定提供了指导方法。

[Objective] The aim was to study on effects of inorganic sodium salt in soil on concentration of zinc ion in different patterns. [Method] Tessier sequential extraction was used to study on effects of inorganic sodium salts （in different species and different concentrations） on concentration of zinc ion in different patterns. [Result] Different inorganic sodium salts had different effects on zinc form. Content of ex- changeable Zn would reduce if Na2CO3 or Na2SO4 was added and the content would increase if NaCI was added. Content of carbonate zinc, which was significantly influ- enced by Na2SO4, would increase if NaCI or Na2SO4 was added, and would decrease if Na2CO3 was added. For Zn bound to Fe-Mn oxides and organic matters, and residual Zn, the contents would decrease if NaCI or Na2SO4 was added and the decrease showed much more significantly if high concentration sodium salts were added. In addition, content of Zn bound to Fe-Mn oxides decreased if Na2CO3 was added. If low concentration Na2CO3 was added, Zn bound to organic matters and residual would increase in content but would lower if high concentration one was added. [Conclusion] The research provided references for measurement of heavy metal ion content in soil in different places.
