| Abstract: | Phytoremediation has been regarded as a suitable technique for the pollution control of heavy metals contaminated soils.In this paper, two methods of efficient improvement of phytoextraction are discussed: first,to improve the uptake of heavy metals by plants by increasing heavy metal concentrations in soil solution;second,to adopt some means based on physiological mechanism of heavy metal hyperaccumulators. |
