Abstract
Effects of red mud and organic fertilizer on distribution of cadmium(Cd) and lead (Pb) in soil-rice system were studied in field by orthogonal test. Results showed that after red mud and organic fertilizer added including single and combined, the soil pH value increased 0.36~1.90 units, contents of Cd and Pb in rice rhizosphere soil decreased 2.73%~26.25% and 7.15%~34.26% respectively and contents of Cd and Pb in brown rice decreased 23.24%~55.90% and 11.76%~29.41% respectively. In all treatments, single red mud was best, followed by red mud and organic fertilizer combined, single organic fertilizer was worst. The content of Cd and Pb in different rice organs wi...
