| 摘 要： | 采用盆栽实验,在铅锌尾矿中添加中药渣、氮肥、磷肥及其组合,从植物生长、营养元素、土壤酶活性、尾矿及植物重金属含量等方面研究其对铅锌尾矿的改良效果.结果表明:添加中药渣配合氮磷肥不同程度地促进了黑麦草的生长,增加了有机质、铵态氮、有效磷含量,提高了土壤酶活性,降低了尾矿及植物中重金属含量,其中中药渣、中药渣+氮肥、中药渣+磷肥,中药渣+氮肥+磷肥处理组效果较好;典范对应分析表明,中药渣、中药渣+氮肥、中药渣+磷肥、中药渣+氮肥+磷肥处理与有机质、铵态氮、有效磷、脱氢酶、β-葡萄糖苷酶、脲酶和磷酸酶有较强的相关性.综合分析表明,在铅锌尾矿的改良修复中添加中药渣作为改良剂,配合氮磷肥施用有助于缓解尾矿重金属毒性,改善营养状况,促进微生物活性,有利于尾矿废弃地的生态恢复.
