Abstract: The screening of hyperaccumulator is one of important problem that the plant repair technology should solve. The soil seed bank was taken as the screening source, the atomic absorption spectrophotometric method was used to determine the Mn content of plants that grow on the Mn gangue soil. The result indicated that there are 13 kinds of plants that can grow on the gangue soil which is rich in the heavy metal of Mn gangue. Digitaria sanguinalis (L.) Scop., Opliamenus undulatifolius (Ard.) Beauv. have the resistance to Mn; Cardamine flexuosa With.can accumulate the excess heavy metal of Mn. The Cinnamomun camphora seed can sprout and grow well, P. ternata (Thunb.) Breit transportation coefficient is the highest, which have the prospect of reuse heavy metal Mn.
