PURPOSE: A greenhouse system capable of supplying nitrogen necessary for the crop cultivation is provided to use the nitrogen in air directly to cultivate crops. CONSTITUTION: A greenhouse system comprises the following: a house(100) supplying a crop cultivating space, and including an air passage.; a plasma generator(200) installed inside the house, generating plasma for reacting nitrogen and oxygen in air and producing nitrate ions; a liquid phase-spraying unit(300) spraying liquid for dissolving the nitrate ions, installed inside the house closely to the plasma generator; a core electrode located inside the air passage of the housing; a peripheral electrode located around of the core electrode; and an air supplying unit supplying external air in the housing toward the tip-end of the core electrode by force. |
