In order to use remediation of contaminated soil and revegetation in Huize lead-zinc mining tailings,it was significant to study of the lead-zinc tolenrance of the symbiosis of the legume-rhizobia in Huize lead-zinc mining tailings.In this paper,the tolenrance to compound lead-zinc stress of the symbiosis of the legume-rhizobia was studied. The results showed that the legume seeds grew natually in Huize lead-zinc mining tailings had the good resistence to compound lead-zinc.The host plants inoculated the two high tolenrance to lead-zinc strains HS3 and HZ8 showed that the capability of host plants to resist compound lead-zinc stress was stronger than those were not inoculated and are sensitive to metal resistence rhizobia.The HS3 and HZ8 could decrease the concentrations of lead-zinc of the surrounding surface of nodule and could be beneficial to the metal lead-zinc tolerance of the symbiosis of legume-rhizobia by the combination of the lead-zinc and the polysaccharides and many other secrations of the nodule surface.The comprehensive reaction mechanism of heavy metal tolenrance to lead-zinc of the symbiosis of legume-rhizobia HS3 and HZ8 is worth studying.
