Soil heavy metal pollution has become an urgent problem to be solved,among many existing remediation technologies,phytoremediation has become a hot research technology because of its environmental friendliness and will not produce secondary pollution,super-enriched plants are a kind of plants with special physiological characteristics,the adsorption capacity of heavy metals and other harmful substances in the soil is much higher than that of ordinary plants,with the advantages of high accumulation and high tolerance.However,the restoration of super-enriched plants also has the limitations of too long restoration cycle,low restoration efficiency and more specific restoration.In this regard,the implementation of a series of strengthening measures has become an effective way to promote efficient plant restoration.In this paper,the characteristics of the current heavy metal pollution and remediation technology are analyzed,the research status and strengthening measures of heavy metal super-enriched plants are reviewed,and finally the prospects are summarized.
