The present invention relates to a greenhouse provided on the ground, comprising: wall portions for forming a cultivation space for plants on the ground (The wall portions comprises a north side wall provided so as to face the north, and inclined side walls extended from both longitudinal sections of the north side wall to be inclined on the ground); a storage portion for accommodating water and air, provided below the bottom surface of the cultivation space along the east and west directions of the north side wall; a temperature control portion, which is placed over the entire inner lateral side of the north side wall, for allowing water to flow such that water is supplied from the storage portion and re-supplied to the storage portion, thereby enabling heat exchange with the cultivation space; a water supply portion for connecting the first longitudinal end of the temperature control portion and the storage portion, and for supplying the water from the storage portion to the temperature control portion so as to allow the water to flow along the temperature control portion; and a roof portion for sealing the cultivation space, placed at the upper surface of the wall portions (bubbles fill the inside of the roof portion). Thus, since the aforementioned greenhouse can maintain a predetermined temperature of the cultivation space of plants irrespective of the changes in the external environment using solar and geothermal heat, it is possible to reduce equipment and maintenance costs of the greenhouse. |
