Title: PLANT CULTIVATION SYSTEM IN PLANT FACTORY
Abstract:
[Problem] To provide a plant cultivation system in a plant factory, wherein, even in the case of raising a vegetable which grows tall in the perpendicular direction, an artificial lighting device can be disposed above the plant as close to the plant as possible. [Solution] A plant cultivation system comprises: a cultivation panel 110 on which a plant to be artificially cultivated is planted; a transporter 130 which transports the cultivation panel 110 in a preset direction; and a light source device 120 which is disposed above the transporter 130 in such a manner as to face to the cultivation panel 110 and on which an artificial light source is mounted. In this plant cultivation system, the relative distance (H) between the light source device 120 and the cultivation panel 110 facing each other varies in accordance with the proceed status of the transportation of the cultivation panel 110 by the transporter 130. Namely, as the transportation of the cultivation panel 110 by the transporter proceeds, the distance (H) is set to increase by the increase in the plant height due to growth. A number of the cultivation panels 110 are aligned in the transportation direction and intermittently moved stepwise toward the downstream side at preset time intervals. When the cultivation panels are transported from the upstream to the downstream, the plant raising period is ended.
