Application of artemisia stolonifera in repairing of heavy metal cadmium polluted soil

Abstract

The invention discloses feverfew artemisia stolonifera, and in particular relates to an application of the Artemisia stolonifera in repairing of heavy metal cadmium polluted soil, namely planting the artemisia stolonifera in the heavy metal cadmium polluted soil. The enrichment of the artemisia stolonifera to the heavy metal cadmium is utilized, the artemisia stolonifera is planted into the polluted soil, the heavy metal cadmium can be absorbed and accumulated, and most cadmium can be transferred to the overground part; and the overground part is subjected to ashing treatment to extract the heavy metal, thus the aim of repairing the heavy metal cadmium polluted soil is achieved. The artemisia stolonifera has strong fertility, can grow rapidly and can grow on extremely poor soil, and management is extensive in the growing process of the artemisia stolonifera, thus the cost is low, the operability is high, and a new plant resource specie used for repairing the heavy metal cadmium polluted soil is developed.

Description

technical field [0001] The invention relates to the technical field of remediation of heavy metal pollution in the environment, in particular to the application of Artemisia broadleaf in remediation of heavy metal cadmium pollution in soil. Background technique [0002] With the rapid development of economic globalization, heavy metal pollution in the global land is becoming more and more serious. Industrial "three wastes" and motor vehicle exhaust emissions, sewage irrigation and abuse of pesticides and fertilizers have caused serious environmental and heavy metal pollution. However, the heavy metal cadmium (Cd) pollution in the environment has the characteristics of concealment, long-term and irreversibility. Its pollutants have poor mobility in the medium, long residence time, cannot be degraded by microorganisms, and can also be transmitted through the food chain, which will eventually affect human health. , causing immeasurable impact. The Japanese bone disease incide...
