The present invention relates to an apparatus for measuring carbon dioxide of a plant and a soil material capable of quickly and easily measuring a carbon dioxide reduction rate, a change rate thereof, and comprehensive carbon flux with respect to various soil materials and plants. The measuring apparatus comprises: an accommodating case in a rectangular cube whose upper part is opened and the inside is hollow to accommodate a plant and a soil material; a frame in the form of a rectangular parallelepiped frame whose lower end is mounted on the upper end of the accommodating case and sealed to be separated, wherein a transparent window is installed in an opening outer surface, and whose upper part and lower part are opened; an upper cover whose one end is hinged to be opened and closed in the upper end of the frame; a pair of operating cylinders mounted between the outer surface of the transparent window and the lateral surface of the upper cover, and opening and closing the upper cover; an outdoor air suction fan installed inside the upper end of the frame to correspond to the lower part of the upper cover, and sucking outdoor air and allowing the outdoor air to flow toward a lower part; a soil respiration measuring sensor installed in the inner surface of the accommodating case, and measuring concentration of carbon dioxide discharged from a soil material accommodated in the accommodating case; and an atmospheric carbon dioxide measuring sensor installed in the inner surface of the frame, and measuring the concentration of carbon dioxide contained in air accommodated inside the frame. |
