Device for regulating mycorrhizal fungi transferring inter-plant nutrients via atmospheric carbon dioxide

The invention discloses a device for regulating mycorrhizal fungi transferring inter-plant nutrients via atmospheric carbon dioxide. The device comprises a mycelia chamber (1), an inoculation chamber (10) and an isotope supplying chamber (4). The device is characterized in that an air separation layer (3) is arranged between two separation plates (14) of the inoculation chamber (10) and the mycelia chamber (1); the two separation plates (14) are provided with a plurality of microholes (9); the tops of the mycelia chamber (1) and the inoculation chamber (10) are opened; the lower part of the inoculation chamber (10) communicates with the isotope supplying chamber (4) and the upper part is provided with a glass cover (2); ventilating holes (11) are formed in the glass cover (2); and the ventilating holes (11) are connected with an isotope air storage tank (5) via a ventilating hose (12). The device regulating mycorrhizal fungi transferring inter-plant nutrients via carbon dioxide can simulate features of atmosp
