Abstract:The components of the tailings in Dachang mine area are very complex,containing many kinds of phytotoxic heavy metals,lacking the nutrition needed by plants,so it is very hard for plants living in the pure tailing environment.Field experiment of plants growth in the Kengma tailings pond indicates that garbage fertilizer treatment can improve the edaphic structure and provide essential nutrition for the plant growth,while the thin soil covering treatment with plant seeds can facilitate the propagation and growth of wild plants species.The experimental result shows that after reclaiming the tailings with garbage fertilizer,Leucaena leucocephala(Lamk) Dewit.can grow well on the tin-zinc tailings pond while it is restricted in the tailings ponds without any reclamation;the contents of As,Pb and Zn in Leucaena leucocephala(Lamk) Dewit.are not high,only a little above those in normal plants.
