英文摘要	Effects of sulfur (s) (0, 30 mg s kg(-1) soil) supply on cadmium (cd) uptake into rice when cultivated in low-cd soil [38.8 mu g kg(-1) for diethylenetriaminepentaacetic acid (dtpa)-extractable cd] and in excessive-cd soil (748.7 mu g kg(-1) for dtpa-extractable cd) were investigated in a combined soil-sand culture experiment. the significant difference in the cd uptake into rice between -s and +s treatments were observed in relation to soil cd levels. when rice was exposed to excessive cd soil, application of s restrained the uptake of cd into rice, the s supply tended to increase cd uptake into rice when cultivated in low-cd soil. the possible mechanisms explaining the interactions among soil cd level, s supply, and cd accumulation in rice are proposed. these results suggest that s fertilization may be important for the development approaches to reducing cd accumulation in rice when cultivated cd-contaminated soils.
