A pot experiment of ‘Shennong 9816’ treated by 0, 2 mg kg-1 cadmium(Cd) and 0, 1.4, 14 g kg-1 biochar were conducted to investigate the effect of biochar on the chemical forms of Cd in rice. The sequence chemical extraction method was used to study chemical forms of Cd in roots, stems and leaves of rice. Results indicated that the highest Cd concentration in vegetative tissues was F3 (extracted by 1 M Nacl), followed by F4 and F5 (extracted by 2% HAC and 0.6 M HCl, respectively). Biochar reduced Cd in F1 and F2 (extracted by 80% ethanol and d-H20, respectively). In conclusion, biochar could reduce the pollution risk of Cd in the food chain, however, the effect of biochar detoxification had not worked from the total Cd contents of rice organs at tillering stage.
