摘　　要：金虹在彩叶草品种中对重金属有相当的适应能力。单独加锌可直接增加彩叶草对铅、锌的吸收,单独增加铜浓度会抑制彩叶草对铅、锌的直接吸收。锌、铜同时增加才会促进彩叶草对铅、锌的吸收。单独增加铜浓度可增加彩叶草对汞的直接吸收。单独加锌与锌铜同时增加都会抑制彩叶草对汞的吸收。单独加锌可直接增加彩叶草对铜的吸收,单独增加铜浓度会抑制彩叶草对铜的直接吸收。锌、铜同时增加才会促进彩叶草对铜的吸收。Jinhong has considerable adaptability to heavy metals in these 10 different varieties Coleus Blumei. The results showed that the absorption of Pb and Zn by Coleus Blumei could be increased by adding Zn alone, while the absorption of Pb and Zn could be inhibited by increasing the concentration of Cu alone. The increase of Zn and Cu at the same time could promote the absorption of Pb and Zn by Coleus Blumei. Increasing the concentration of copper alone can directly increase the absorption of Hg. However, the absorption of Hg would be inhibited by Coleus Blumei through the addition of Zn alone or increase of Zn and Cu at the same time. Adding Zn alone can directly increase the absorption of copper by Coleus Blumei, but increasing the concentration of copper alone can inhibit the absorp-tion of copper by Coleus Blumei. Only when Zn and Cu were increased at the same time could promote the absorption of copper by Coleus Blumei.
