Abstract: A field plot experiment was conducted to assess the application effect of soil conditioners on acid cadmium (Cd) contaminated paddy field in Xinyu, Jiangxi Province. The effects of five mineral conditioners including oyster shell and limestone on soil Cd, Cd content in different organs of rice and yield were analyzed. The results showed that compared with the control, the application of mineral conditioners increased soil pH values by 1.17 - 1.69 units and cation exchange capacity by 13.1% - 41.2%. Soil available Cd content was decreased 0.25% - 18.8%, while the Cd contents in rice roots, stems, leaves, husks and brown rice were significantly reduced by 4.81% - 48.0%, 44.7% - 84.9%, 38.5% - 76.9%, 45.8% - 79.2% and 43.4% - 75.5%, respectively; and the rice yield was increased by 0.81% - 17.9%. The concentration factor of Cd in different organs of rice was in the following order: root > stem > leaf > brown rice > husk. The Cd in rice was mainly enriched in root, stem and leaf. The Cd content in each organ of rice was significantly positively correlated with the soil available Cd（P < 0.01）, but negatively correlated with soil pH (P < 0.01). The mineral conditioners exhibit better resistance and control effect on the migration and redistribution of Cd in the soil-rice system, which have yield-increasing effect and potential to ensure the safe production of rice.
