Abstract
The effects of CO_2 enrichment on the allocation of biomass,C and N accumulation in rice organs under 2 levels of N were studied.The results shown that the elevated CO_2 decreased significantly the allocation of biomass and C content in rice leaves and increased their allocation in shoot,ear and root,decreased the allocation of N content in leaves and increased the allocation in ear.Under lower N and normal N treatments,the allocation of N in root decreased by 9.67% and 13.1% respectively at heading stage and increased by 3.5%～26.6% at other stages,the allocation of N in shoot increased by 7.03% and 5.71% at jointing stage and decreased by 10.5% and 7.43% at ripening stage respectively.There was not significant influence of N levels on the allocation of biomass,C and N in rice organs.
