The aim of this study was to investigate the influence of amendments of Mn mining tailings with red soil on the phytoextraetive potential of Mn by four plant species

such as Phytolacca acinosa

Phytolacca americana

Polygonum lapathifolium

Amaranthus paniculatus. Pot culture experiments were conducted by using Mn mining tailings diluted with red soil in different ratios. Amendments of Mn mining tailings with red soil were friendly to growth of the four plant species. The biomass for P. acinosa

P. americana

A. paniculatus

growing in sub- strates with 20%-100% Mn mining tailings

were significantly higher than that in controls without Mn mining tailings. In all treatments

the biomass of P. acinosa and P. americana were higher than that of the other two species. In T80 treatments

P. acinosa

P. americana and A. panuculatus grew normally and Mn extraction by them were the highest value for all treatments. The results showed that P. acinosa

P. americana were more adaptive and tolerant to Mn mining tailings than the other two species. P. acinosa

P. americana were the most suitable species and should be first selected for phytoremediation on sites contaminated by Mn mining tailings. In order to reconstruction of a stable ecosystem with more plant species

A. paniculatus may be co-planted with them. The T80 amendment approach

in which Mn mining tailings in substrates was 80 %

was the more reasonable for reclamation in sites polluted by Mn mining tailings.
