- 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.
