Research Abstract

We investigated that the cadmium concentration and the yields of rice plants by using two models of stratified paddy fields. The plowsole in those models was made of polluted soil. The range of cadmium concentration in both models in brown rice was 0.000-0.200 mg/kg. Cadmium concentration in brown rice with water flow in an open system became higher than that with water flow in closed system. We realized that percolation patterns did not influence the growth of rice plants. The number of panicles and the weight with water flow in closed system became higher than those with the water flow in the open system.
