Plant cultivation house for cold regions

摘要

PROBLEM TO BE SOLVED: To provide a plant cultivation greenhouse effectively collecting solar heat in the plant cultivation greenhouse so as to secure a temperature rising in the greenhouse, and allowing plant cultivation of agricultural crops throughout the year without using a large amount of fossil fuel.SOLUTION: The plant cultivation greenhouse for cold districts includes a roof in which the inclination of an inclined roof surface is steep, and the whole is a triangle section in the longitudinal direction, and a vertical wall surface. The plant cultivation greenhouse for cold districts heats culture soil in the greenhouse by covering the roof part and the sidewall part in the longitudinal direction of the plant cultivation greenhouse with a double transparent and/or translucent frame forming film, setting a reflection film reflecting solar light in the inside on a roof part whose most part becomes a shady place during the day, setting an air inhalation duct inhaling high temperature air set in the longitudinal direction on the upper part of the ceiling of the roof with a triangle cross section, blasting high-temperature air taken into the air inhalation duct, and supplying the high-temperature air or heated water by the high-temperature air to heating piping installed in the ground of culture soil in the plant cultivation greenhouse.
