PROBLEM TO BE SOLVED: To provide a plant cultivation greenhouse that effectively collects solar heat into the greenhouse to ensure temperature rise in the greenhouse and is capable of raising farm products through the entire year without using a large amount of fossil fuel.SOLUTION: There is provided a plant cultivation greenhouse for cold regions in which inclination of a roof slope is made steep, a roof has rectangular cross section in a longitudinal direction over the entire roof, and sidewalls are made perpendicular. A roof part in the longitudinal direction of the plant cultivation greenhouse and a sidewall part are covered by a double transparent and/or a translucent frame forming film, an air suction duct that sucks high-temperature air is provided for an upper part of a ceiling of the roof having rectangular cross section in a longitudinal direction, high-temperature air taken into the air suction duct is sent to a heat exchange coil of a heat storage water storage tank, air in the greenhouse is stirred by the air after heat exchange, warmed-up water in the heat storage water storage tank is supplied to a heating pipeline that is laid in the ground of a cultivation ridge in the plant cultivation greenhouse, and the cultivation ridge in the greenhouse is heated. |
