PROBLEM TO BE SOLVED: To provide a movable light reflection device for cultivation, capable of applying the plant cultivation by an elevated cultivation bed and of easily selecting an optional reflection angle with a simple configuration, and to provide a cultivation method using the device.SOLUTION: The movable light reflection device for cultivation 1 comprises: a light reflective surface member 2 for cultivation in which a first side border 3 is installed to the side 102 of the elevated cultivation bed 100 a plurality of support bar materials 5 which push upward and support a second side border 4 facing the first side border 3 of the light reflective surface member 2 and a linear member 6 which is provided along the lengthwise direction of the bed 100 and is interlocked to the support bar materials 5. The angle of the light reflective surface member 2 is changeable by the movement of the linear member 6 along the lengthwise direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】この発明は、高設栽培ベッドによる植物栽培に適用でき、簡易な構成で簡単に任意の反射角を選択できる可動式栽培用光反射装置およびこれを用いた栽培方法を提供することを目的とする。【解決手段】上記の課題を解決するために、この発明の可動式栽培用光反射装置1は、高設栽培ベッド100の側部102に第1側辺3を取り付けられる栽培用光反射面部材2と、栽培用光反射面部材2の第1側辺3に対向する第2側辺4を上向きに押し上げて支持する複数の支持棒材5と、高設栽培ベッド100の長さ方向に沿って設けられ支持棒材5に連結された線状部材6を有し、長さ方向に沿った線状部材6の移動により栽培用光反射面部材2の角度を変えるものである。【選択図】図1
