Abstract: The cadmium pollution of rice become increasingly serious, which caused enormous threats to human health and agricultural production. In order to find an effective way to control the cadmium content in rice, to meet the national safety levels and to provide a theoretical basis for the subsequent test, this study took the low-cadmium accumulation rice Xiangwanxian 12 as the experimental material by applying the randomized blocks design to explore and compare with five control technologies including VIP [low cadmium species（variety） + reasonable irrigation （irrigation）+ adjust the acidity （pH）] and 12 test points that have different soil parent materials and extent of soil contamination. The result showed that the effect of “VIP + Se” and “VIP + Se + Bi” treatment were better than other treatments, and the effects of cadmium reduction were significant compared with the control.
