According to the results of the experiment in this paper, they show that the effects of three kinds of fertilizers on the leaching of heavy metals are different, and related to the fertilizers concentration. The carbamide can promote the leaching of Cu, on the contrary, the potassium obviously repress the leaching of Cu, and when concentration of potassium is 0.5mol/L, Cu scarcely leach.%针对3种化肥对土壤重金属溶出性影响进行了研究,试验结果表明：3种化肥对土壤中重金属的溶出性有不同的影响,而且与化肥的浓度有关,其中尿素和硝酸铵钙对Cu的溶出有较大促进作用,而钾肥对Cu的的溶出有明显的抑制作用,且当浓度达到0.5mol/L时,Cu几乎不溶出。
