| 摘 要： | 16个土壤剖面的 77个土样的铜素含量及剖面与形态特征研究表明 ,果园由于长期大量使用含铜农药波尔多液等 ,表层土壤全铜含量明显高于对照 ,超过土壤环境质量规定的二级标准 ;果园土壤中的交换态铜、有机态铜和沉淀态铜的分配系数比对照土壤明显增加 ;随着剖面层次的加深 ,各形态的铜含量逐渐降低 ,与对照土壤的差别逐渐减少 ,说明外源铜主要对表层和亚表层土壤产生深刻影响 |
| 关 键 词： | 果园土壤 铜素含量 形态特征 剖面特征 |

| Abstract: | The contents, section characters and form characters of copper in 77 soil samples of 16 soil sections were evaluated: Because of slather pesticides containing copper,the content of copper in the topsoil of orchards had been distinctly higher than in the controls, exceeding the second standard stated by soil Environment quality standards. The distribution coefficient of the EX-Cu, OM-Cu and RES-Cu distinctly increased. With the soil depth going deep, the contents of all forms of copper decreased.In addition,the additional copper mainly brought profound effects on the topsoil and sub-topsoil. |
