| Abstract: | Objective] The research aimed to decrease the contents of the heavy metals in the soil.Method] The regularity of the distribution and the migration of As,Ni,Cd and Pb in the different parts of the maize was analyzed when different concentrations of fulvic acid were added to the heavy metals polluted soil.Result] The content of As,Ni,Cd and Pb in the maize were increased with the increase of the concentration of fulvic acid.The distribution sequence of heavy metals in the different part of the maize was root> stem > leaf > grain.Conclusion] Fulvic acid promoted the Absorption of heavy metals in the maize. |
