To provide a multi-stage plant cultivation shelf with low temperature and humidity variations depending on the installation position of a cultivation tank at low cost. A skeleton structure is assembled using at least a plurality of support pillars 111 and a plurality of beam members 112 laid side by side along the height direction between the support pillars 111, and straddles the beam members 112. Thus, a plurality of cultivation tanks 122 are installed. And the work channel path part 131 using the grating material 131a and the channel path part 132 between tanks using the mesh tread 132a are installed adjacent to the cultivation tank 122 for every predetermined step. Since the frame structure 110 is composed of the pillars 111 and the beam members 112, and the grating members 131a and the mesh treads 132a are used for the work passage portions 131 and the inter-tank passage portions 132, the multi-stage plant cultivation shelf 100 as a whole The air permeability becomes very good. As a result, variations in temperature and humidity due to the installation position of the cultivation tank 122 can be reduced. [Selection] Figure 1【課題】栽培槽の設置位置による温度・湿度のバラツキが小さい多段式植物栽培棚を安価に提供する。【解決手段】複数本の支柱１１１と、これら支柱１１１間に高さ方向に沿って並べて架設された複数本の梁部材１１２とを少なくとも用いて骨組構造１１０を組み立て、これら梁部材１１２に跨がって複数の栽培槽１２２を設置する。そして、所定段毎の栽培槽１２２に隣接して、グレーチング材１３１ａを用いた作業通路部１３１とメッシュ踏み板１３２ａを用いた槽間通路部１３２とを設置する。骨組構造１１０を支柱１１１や梁部材１１２で構成すると共に、作業通路部１３１や槽間通路部１３２にグレーチング部材１３１ａやメッシュ踏み板１３２ａを使用するので、多段式植物栽培棚１００全体としての垂直方向の通気性が非常に良好となり、その結果、栽培槽１２２の設置位置による温度・湿度のバラツキを低減できる。【選択図】図１
