摘　　要：采用室内培养方法研究了不同氯化物KCl、NH4Cl、MgCl2、CaCl2和FeCl3作为添加剂对土壤中铜的活性影响。结果表明,施用各种添加剂都可增加土壤中水溶态和交换态铜含量以增加土壤铜的活性,且随着投加的氯化物浓度的增加而增加,其中FeCl3对土壤铜的活化能力最强,而KCl对土壤铜的活化能力最弱。Influence of different chloride salts including KCl, NH4Cl, MgCl2, CaCl2 and FeCl3 on activation of copper in soil was conducted. The results revealed that water soluble form and exchangeable form were enhanced by using chloride salts to enhance the activation of copper, and was positive correlation with concentration. Of several chloride salts, FeCl3 was the strongest in activating copper,while KCl was the weakest.
