This study was conducted to find out the effect of municipal sewage sludge application on the yield and the heavy metal content in Paeonia abliflora Pall root. When the municipal sewage sludge was applied to the soil, the yields and growth of Paeonia abliflora Pall increased, and the contents of T-N, P in soils increased, while there is no difference in contents of heavy metals and inorganic materials in roots. Therefore, it is apparent that the contents of heavy metals in roots of paeonia abliflora Pall would not due to increase with the municipal sewage sludge application.
