Abstract： The phenomenon of excessive cadmium in rice still occurs in a certain range in China. The control of cadmium pollution is the key and difficult point in the current and future agricultural product quality safety work. Based on the physicochemical properties and toxicity of cadmium， the source and distribution of cadmium in rice， the control methods of physical cadmium reduction， chemical cadmium reduction and biological cadmium reduction were analyzed， and the relevant countermeasures and suggestions were put forward to provide reference for the prevention and control of cadmium pollution in rice.
