Abstract:: The effects of compound stresses of Zn and Cr on carbon and nitrogen metabolisms of rice plant were investigated in a soil pot experiment at tillering stage. The results showed as follows:with increasing of concentrations of Zn and Cr, the biomass of rice plant had a trend to reduce, and the ratio of root/shoot and soluble carbohydrate content of rice roots had an increasing trend, but soluble carbohydrate content of stem and sheath and leave reduced, and soluble protein and total nitrogen contents of roots, stem and sheath and leave changed wavely. Partial correlation analysis showed that concentrations of Zn and Cr in the soil had synergy effect on soluble carbohydrate content of roots, stem and sheath and leave, and soluble nitrogen content of roots. There was no compound effect on total nitrogen of rice plant. Those explained that rice plant adjusted the relationship between source and library to enhance its ability of ecological adaptation under the heavy metals stresses.
