| Abstract: | The basic concept and main ways of phytoremediation were illustrated.The basic principles,restrictive factors and strengthening measures for phytoremediation of soils contaminated by heavy metals were discussed according to their relationship with compounds and forms in the soils.Uptake,excretion and accumulation of plant to heavy metals,biological traits of hyperaccumulators,and the capability and improving technology were also disscussed. It was suggested that the adoption of modern agriculture technology would be a short cut to the commercial application of phytoremediation to heavy metals. |
