Study on the Accumulation Property of Cu in the Different Artemisia Plants

The author choosed six kinds of Artemisia plants as subject investigated around the golden mineral at tongguan county,including Artemisia divaricata(Pamp.) Pamp,Artemisia annua L.,Artemisia selengensis,Artemisia capillaries,Artemisia anethoides Mattf.and Artemisia argyi.Through determining the content of heavy metal Cu in different plants,the author establishes the plant species of artificial ecosystem.The results showed that the absorbing capacity for the same plant increases with the Cu content increasing.Among six kinds of plants in nine different places,the Artemisia annua L.-XI had the best absorbing capacity to Cu,the concentration coefficients was 0.92,and Cu was mostly stored in plant leaves.Respectively Speaking,Artemisia argyi ① also had higher concentration coefficients and it's 0.87.The concentration capacity of Artemisia selengensis leaves in two places were higher,and it was 78.32 mg/kg for Artemisia selengensis-13 and 69.21 mg/kg for Artemisia selengensis①.
