<p>PROBLEM TO BE SOLVED: To provide a plant cultivation device capable of cultivating plants different in an irradiation condition of optimum light in one facility at the same time.SOLUTION: A plant cultivation device comprises: a support plate 2 provided with a substantially annular loading area A; a lighting tool 3 irradiating light to a tray on the support plate; and a light shielding member 4 covering part of the loading area to shield light irradiated by the lighting tool. The lighting tool and the light shielding member are provided to an opposite side with respect to the center of the loading area, and the relative positional relationship is fixed. Light irradiation by the lighting tool is obliquely performed in a vertical plane with respect to the loading area. The support plate is relatively rotated about the center of the loading area as a rotational center, with respect to the lighting tool and the light shielding member.</p> |
