PURPOSE: A multi-stage greenhouse system is provided to prevent the environmental contamination by using soft coal or oil for maintaining the temperature in a greenhouse during winter. CONSTITUTION: A multi-stage greenhouse system comprises the following steps: a transmission type greenhouse(200) installed on the upper side of a shade type greenhouse; thermal storage walls(110,210) absorbing and emitting heat from the transmission type greenhouse for controlling the temperature; and a buried type greenhouse with a semi-underground structure for shielding sunlight on the lower side of the shade type greenhouse. The shade type greenhouse and the buried type greenhouse are formed in a concrete structure. |
