Progress and prospect of plant remediation technology joint with other technologies for heavy metal contaminated soil

With the development of industry and economy,soil pollution of heavy metals tends to be more and more serious.Therefore,remediation of heavy metal contaminated soil has become an urgent issue.Since plant remediation technology has economical and environmental advantages,it has become a research hotspot.However,the rareness of remediation plants limits its application.Plant remediation technology joint with other technologies may be the key to break the limitation.Plant remediation technology joint with genetic engineering technology was reviewed.Plant growth promoting rhizobacteria and mycorrhizal fungi in plant remediation technology joint with microorganism technology were summarized.The application status of plant remediation technology joint with chemical materials was introduced,mainly including soil amendments and chelating agents.At last,the future research and application directions of plant remediation technology joint with genetic engineering,microorganism and material chemistry technologies was prospected,aiming to provide more new thoughts and references for the development of plant remediation technology.
