We used a greenhouse to evaluate the effect of open system and closed system percolation on the accumulation of cadmium (Cd) in various parts of rice plants using a stratified 3.39mg/kg cadmium-polluted paddy field model with 12.5cm of soil dressing. Accumulation of Cd in all parts of the plant (roots, stems, leaves and grains) was found to be higher for open system percolation compared with closed system percolation models. Cadmium uptake in rice plants was enhanced in the open system percolation model due to the interaction with oxidation and reduction reactions. An oxidation-reduction value below-200mV in the closed system percolation model was effective for reducing cadmium accumulation in rice plants.
