The invention discloses application of malva to remediation of cadmium and lead pollution of mine soil and sludge, which is characterized by planting malva in the mine soil or sludge polluted by heavy metals. The invention has the following beneficial effects: the malva is planted in the mine soil or sludge by utilizing the enrichment characteristics of malva toward cadmium, lead and other heavy metals, and can absorb the accumulated heavy metals such as cadmium, lead, etc, and most malva is transported above the ground to achieve the aim of remediating heavy metal pollution of mine soil and sludge; the malva 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.
