PROBLEM TO BE SOLVED: To provide an inexpensive plant cultivation shelf in which, even if light sources such as LED are directly above cultivating plants to be cultivated, irradiation light is not blocked by leaves at an upper position but also efficiently irradiated on leaves at a lower position.SOLUTION: There is provided a plant cultivation shelf in which a plurality of light sources 2a,2b,2c are arranged in a direction, a height and an array gap so as to oppose cultivating plants 3 above the direction of gravitational force and such that irradiation light from the light sources is efficiently irradiated toward the cultivating plants, side face diffusion plates 1a,1b,1c,1d for diffusing irradiation light from the plurality of light sources are arranged between the array gap in the plurality of light sources and between the plurality of light sources and the cultivating plants, and the diffusion plates are arranged on a side face of the cultivating plants.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】LEDなどの光源が栽培される栽培植物の真上にあったとしても、照射光が上部にある葉にさえぎられることなく下部にある葉にも効率良く照射される安価な植物栽培棚を提供する。【解決手段】光源2a、2b、2cが、栽培植物3に対向して重力の向きに対して上方で、前記光源からの照射光が前記栽培植物に向けて効率的に照射されるような向きと高さと配列間隔で複数配されており、前記複数の光源からの照射光を拡散させるための側面拡散板1a、1b、1c、1dが、前記複数の光源における前記配列間隔の間であって前記複数の光源と前記栽培植物との間に配されており、前記拡散板が、前記栽培植物の側面に配した植物栽培棚。【選択図】図1
