酸模叶蓼在修复矿山土壤及污泥重金属污染中的应用
摘要：
本发明公开了一种酸模叶蓼在修复矿山土壤及污泥的镉、铜、铅、锌重金属污染中的应用，将酸模叶蓼种植于重金属污染的矿山土壤或污泥中即可。利用酸模叶蓼对镉、铜、铅、锌等重金属的富集特性，将其种植于矿山土壤或污泥中，可吸收积累镉、铜、铅、锌等重金属，并将其大部分转运到地上部分，以达到修复矿山土壤和污泥重金属污染的目的。在其生长过程中不需要进行特殊管理，因而成本较低、可操作性强；同时也为矿山土壤及污泥中重金属污染的植物修复开发了新的植物资源品种，为植物修复技术的深入发展带来了新的进步和发展空间。
摘要（英）：

The invention discloses application of dockleaf knotweed to remediation of cadmium, copper, lead and zinc pollution of mine soil and sludge, which is characterized by planting dockleaf knotweed in the mine soil or sludge polluted by heavy metals. The invention has the following beneficial effects: the dockleaf knotweed is planted in the mine soil or sludge by utilizing the enrichment characteristics of dockleaf knotweed toward cadmium, copper, lead, zinc and other heavy metals, and can absorb the accumulated heavy metals such as cadmium, copper, lead, zinc, etc, and most dockleaf knotweed is transported above the ground to achieve the aim of remediating heavy metal pollution of mine soil and sludge; the dockleaf knotweed dispenses with special management in the growth process, thus the cost is lower and the operability is strong; and meanwhile, the invention develops new plant resource varieties for remediation of plants polluted by heavy metals in the mine oil and sludge and brings new progress and development space for deep development of plant remediation technology.
