摘要：

On the basis of conventional agronomic measures, the remediation of cadmium (Cd) polluted soil by the Cd accumulator plant Beta vulgaris var. cicla L. was studied in this paper. The influence of nitrogenous fertilizer ((NH4)(2)SO4, CO(NH2)(2), NH4Cl) and potassium fertilizer (KCl, K2SO4, KNO3) on the Cd bioaccumulation coefficient, trans location factor, Cd accumulation quantity by plant and Cd species distribution in soil, was researched through pot experimentation. The results showed that (NH4)(2)SO4 had no significant role in improving the total biomass of Beta vulgaris var. cicla L., while CO(NH2)(2) and NH4Cl could significantly improve the total biomass of the plant. Three kinds of N fertilizer treatments could significantly promote the Cd absorption from roots. Furthermore, all the K fertilizer treatments could significantly promote the Cd absorption via root and the aboveground portions of the plant. Comparing the total Cd accumulation quantity by plant, the effect of N, K fertilizers was CO(NH2)(2)>KCl>NH4Cl>(NH4)(2)SO4>KNO3>K2SO4 >CK.
