Abstract


Modified bentonite(MB) was added in culture solution with different concentration of Cd to inhibit migration of Cd from culture solution to rice seeding. Biomass of rice, Cd concentration of culture solution over time and Cd concentration of different organs of rice were determined. The result showed that MB could improve growth of rice in the culture solution with no Cd was added. MB could decrease Cd concentration of culture solution for its good adsorption on Cd, but it did not completely immobilize Cd in culture solution. Adding MB in culture solution with Cd only alleviate poison of Cd on rice.
