Abstract:

This paper briefly analyzed the characteristics of the control technologies of heavy metal pollution in farmland in southern China. 40 species of hyperaccumulators for cadmium, arsenic, copper and lead in China were collected, classified and summarized. Based on the existing heavy metal hyperaccumulators in China, the selection and cultivation direction of remediation plants in farmland with excessive heavy metals in southern China were discussed. Suggestions for the application of hyperaccumulators in the remediation of farmland with heavy metal cadmium, arsenic, copper and lead pollution were put forward.

Key words: southern China, farmland, excessive heavy metals, phytoremediation, hyperaccumulators
