Abstract:: Effect of CO₂ capture and storage(CCS) technology for CO₂ leakage on C₄ crops biomass is simulated to provide basic information for the potential effect of CCS technology for CO₂ leakage on environment. With the help of artificial CO₂ climate chamber, the impacts of CO₂ on the plant dry weight, root-shoot ratio and dry-wet weight ratio of four C₄ corps such as corn, sorghum, millet and broom corn millet were examined under the condition of CO₂ concentrations of normal, 10 000, 20 000, 40 000, and 80 000 mg/kg by simulating the environment of high CO₂ concentration resulted from CCS technology for CO₂ leakage. When CO₂ concentrations reach to 10 000 mg/kg and 20 000 mg/kg, plant dry weight will increase， root-shoot ratio and dry-wet weight ratio of four C₄ corps will decrease, but as the CO₂ concentrations reach to 40 000 mg/kg and 80 000 mg/kg, plant dry weight will decrease， root-shoot ratio and dry-wet weight ratio of four C₄ corps will increase compared with the control group. With the increase of experiment days, root-shoot ratio and dry-wet weight ratio of four C₄ corps will gradually decrease. When CO₂ concentration is 20 000 mg/kg, plant dry weight of four C₄ corps reaches the maximum value, while root-shoot ratio and dry-wet weight ratio of four C₄ corps reach the minimum values, at this time, it is more advantageous to the growth of the aerial parts and more conducive to use of water.
