PURPOSE:To raise thermal efficiency, save energy and carry out water culture of plants by arranging plant cultivation beds in the vertical direction, moving lamps at a prescribed speed near the surface, enhancing the land efficiency and bringing the lamps close to the plants. CONSTITUTION:A pair of perforated panels 11 and 11 are vertically provided opposite at a prescribed gap (S) and both sides are fixed with side frames 13 and 13. Spacers (13A) and (13A) are interposed between the panels 11 and 11. Many vertical type plant cultivation beds 10 having troughs (11C) of a funnel- shaped cross section are attached to the tips of the gap (S) and fibrous entangled units 12 nipped in the gap (S) are installed on moving frames 16 equipped with casters (16A) crosswise side by side on rails (17A) in a base frame 17. Plural lamps 18 are arranged between the beds 10 in the transverse direction, supported on frame units (18A) and hung from rails (18C) through rollers (18B) on the tip. The lamps 18 are then moved at a prescribed speed to improve land and energy efficiencies and carry out water culture of plants. |
