Abstract：Medium metal contaminated soils were selected to explore Cd repairing in rice by based and foliage manganese fertilizer.The experiment was consisted of three treatments including sulfate manganese,chelating manganese,carbonate manganese applied into soil by non-used fertilizers (CK),the manganese fertilizer applied into soil (TMn),the manganese fertilizer applied into foliar (YMn) and the manganese fertilizer applied into soil combined with foliar spray (TMn+YMn).The research examined Cd concentrations migration rules,and the results showed that,compared to CK,manganese fertilizer had significant impacts on decreasing Cd in brown rice.In addition,TMn+YMn had the best effects to decrease Cd in grains,which resulted in Cd concentrations of husk and brown rice reduced by 31A8％～41.20％,24.77％～34.86％,followed by TMn and YMn.Cd concentrations of husk and brown rice reduced by 10.19％～15.74％,3.67％～12.48％ with TMn,and reduced by 6.02％～15.28％,5.50％～11.01％ with YMn.To conclusion,TMn and TMn+YMn were confirmed as potential Cd pollution control technologies to rice.
