Abstract: ChinaIn order to reveal the effects of adding mycorrhizal in soil compound contaminated by Pb，Zn and Cd on the biomass and nutritions absorption of maize，a pot experiment was carried out.The results show that inoculation Glomus mosseae and Glomus intraradices the effect of maize shoots biomass was not significant，but the maize roots biomass was increased by 13.16% and 34.21% respectively.Mycorrhizal infection rates of maize root was increased by 24.14% and 25.41% through the treatment of  Glomus mosseae and  Glomus intraradices.The P concentration of maize shoots and roots was not significantly increased by  Glomus mosseae compared with the control groups，but P concentration of maize shoots and roots were increased by 16.66% and 10.70% respectively，and the phosphorus of maize roots was moved to the shoots by  Glomus intraradices.Compared with the control groups，the concentration of Mn in maize shoots were not significantly increased，but concentration of Mn in maize roots were significantly increased by 44.93% and 53.04% respectively.Concentration of Fe in maize shoots were slightly decreased，and concentration of Fe in maize roots were increased by 4.15% and 37.80% respectively，this shows that the  Glomus intraradices  could promote Fe absorptions by roots of maize.The concentration of Ca in maize shoots were increased by 36.97% and 18.50% respectively through the treatment of the two mycorrhizals，but there were not significant effect in maize roots，and this shows that the calcium in maize roots was significantly moved to the maize shoots.
