Along with the increase of Cu concentrations in different treatments, the Cu content in Elsholtzia Splendens Nakai presented two types with different increasing rates during growth stage, and treatment of Cu 200 mg/kg in soil played as a turning point. Plant Cu concentration was positively correlated to soil Cu content when soil Cu concentration was not more than 200 mg/kg. At the early flowering stage, treatment of Cu 400 mg/kg had maximum Cu extraction of 27.2 mg per pot, but its Cu removing rate was only 1.30%. At the blossom stage, plant Cu contents in each treatment were much higher, compared with the early flowering stage. The maximum extraction of Cu reached to 143 mg per pot in the treatment of Cu 400 mg/kg, the removing rate was significantly higher than that at early flowering stage (p<0.05), with the value of 6.85%.
