摘要

以棕壤为供试土壤

采用室内土柱淋溶模拟试验方法

研究了相当于泰安平均年降水量条件下铜在土壤垂直方向上的迁移转化特征.结果表明:各处理土壤中的铜在0～10 cm土层中均有不同程度的迁移转化.土壤铜含量越高

年降水量条件下表层土壤中铜的淋失量越大

沉淀态铜和矿物残留态铜所占的比例增加了28.57%～33.49%.高铜土壤中

钙含量的增加使交换态铜比例降低幅度为9.97%～10.48%

使铜的迁移量最大可减少15.54%;随褐煤施入量的增加

表层交换态铜含量减少

铜向5～10 cm土层中的淋溶量减少显著

有机结合态铜的含量增加22.76%～36.07%.

Abstract

Soil column is used to study the characteristics of the movement of copper in uprightness direction in brown soil which is in one year rainfall condition in Taian.The result shows that the higher the content of copper in soil

the more leaching loss

the content of SUB-Cu and RES-Cu increases by 28.57% to 33.49%.In the soil of high content of copper

the proportion of EX-Cu decreases by 9.97% to 10.48% and the movement of copper decreases by 15.54% with the content of calcium increasing;with the increasing of brown coal input to soil

the content of ex-Cu in the surface layer decreases

the leaching loss of copper decreases distinctly which moves to the layer of 5~10 cm and the content of OC-Cu increases by 22.76%~36.07%.
