Paper Title:
Research on Effect of Copper on Chlorophytum Comosum-Soil System
  Abstract

In this study, Chlorophytum comosum was used to restore the artificially polluted soil by pot-planting. The results showed that the sensitivity of soil enzymatic activities was ranked as follows: urease > invertase > phosphatase > catalase, as their activities were only 25.71%, 33.33%, 37.88% and 55.49% compared to CK. The electrical conductivity (EC) value of soil increased from 98.3 to 608.7 µs·cm-1 with the increase of copper (Cu) concentration in soil, but the organic matter had no significant difference between different treatments. The bioaccumulation coefficients (BC) and translocation factors (TF) value of C. comosum were both above 0.5 when Cu concentration in soil was up to 500mg·kg-1, which indicated that there might be an excellent and transport mechanism in C. comosum. In conclusion, C. comosum is a potential ornamental plant in recovering Cu-contaminated soils.
