Abstract：The application of combined amendment in cadmium (Cd)-contaminated paddy soil can reduce the accumulation of Cd in rice grain, thus improving the safety level of agricultural products. In the present study, we conducted a plot experiment to examine the effect of the combined amendment of SF (the mass ratio of sepiolite to ferromanganese ore powder is 5:1) on soil Cd availability, the concentration of Cd in Fe-Mn plaque in roots, and the uptake and accumulation of Cd in rice plants under different application rates (562.5, 1125 and 2250kg/hm2). The results showed that the application of SF had no significant effect on the concentration of available Cd and Fe in the soil, but increased the concentration of available Mn and exchange Mg. Compared with CK, the concentrations of Fe and Mn in Fe-Mn plaque in roots of SF treatments increased by 6.9%~22.1% and 15.6%~84.4%, respectively, and the concentrations of Cd in Fe-Mn plaque in roots significantly decreased by 25.8%~37.3% (p<0.05). The concentrations of Cd in roots treated with SF were significantly reduced by 25.3%~50.2% (p<0.05), and the Cd concentrations in rice grains were significantly reduced by 35.9%~45.3% (p<0.05). The Cd concentrations in rice grain was positively correlated with the Cd concentrations in root and Fe-Mn plaque (p<0.05). The application of the combined amendment of SF significantly reduced the Cd concentrations in rice grains by reducing the adsorption of Cd by Fe-Mn plaque and the uptake of Cd by rice roots.
