The invention relates to a plant remediation technology for a soil polluted by heavy metal of cadmium, and discloses a method for remediation for soil polluted by cadmium by utilizing eucalyptus grandis of Myrtaceidites. In the technology, the eucalyptus grandis is planted in the soil polluted by heavy metal of cadmium, and the accumulated heavy metal of cadmium is absorbed by virtue of the enrichment characteristic of the plants of the eucalyptus grandis on the cadmium, and most of the cadmium is transported to the overground parts of the plants; and litters such as fallen leaves, fallen branches and fallen barks of the eucalyptus grandis are collected in late autumn every year, and the eucalyptus grandis is cut after being planted for three years, an ashing treatment is performed, and the heavy metals are extracted, so as to achieve a purpose of remediation for the soil polluted by the cadmium. The eucalyptus grandis is rapid in growth, high in biomass, and capable of holding and absorbing heavy metals, remaining stumps to branch out, performing continuous remediation for the soil polluted by cadmium, raising the virescence level of the districts polluted by heavy metals, and creating environmental benefits. The saplings of the eucalyptus grandis are convenient to obtain, low in price, simple in plantation and management, and convenient for engineering utilization.
