Water culture was used to study the regulation effect of metal divalent micronutrient elements including Cu2+, Zn2+, Mn2+ and Fe2+ on Cd accumulation in rice plant in different nutritional environments. The results indicated that the supply level of whole necessary nutrient elements or single divalent micronutrient element was very important factor which regulated Cd accumulation in rice plant. As  the supply ratio of whole necessary nutrients in solutions contained with Cd2+at 2 μmol/L increased from 0.25 to 2.0, the Cd content of root and stemleaf of the rice plant  decreased by 42.5% and 64.5% respectively. As adding single divalent metal nutrient element into a designed basic solution with Cd2+ but no other divalent necessary metal nutrient elements, the Cd content of the roots treated with Ca2+,Mg2+,Fe2+,Zn2+,Mn2+or Cu2+ decreased to 15.4%〖KG-*3〗~61.6% comparing with CK, and the Cd content of the stemleaf except the adding Ca2+ treatment decreased to 202%〖KG-*3〗~875% comparing with CK Excess supply of Zn2+ or Mn2+ in Kimura solution B stimulated strongly Cd accumulation in root, stemleaf and grain The Cd content of root, stemleaf and grain increased by 455%, 1774%, 2508% respectively treated with excess supply of Zn2+andincreased by 202%, 1174%, 2271% treated with excess supply of Mn2+ Cu2+ strongly inhibited the adsorption of Cd2+ by rice plant Excess supply of Cu2+ led to a remarkable decrease of Cd content of root, stemleaf and grain by 514%,452%,522% respectively, whereas Cu2+ deficiency led to a remarkable increase of  Cd content of root, stemleaf by 177%,114% respectively The results implicated that appropriate supply of Cu fertilizer, controlling the input of Zn and Mn, maintaining a higher nutrients supply level of soil would be  possibly potential measures to control the Cd accumulation in rice plant
