PROBLEM TO BE SOLVED: To provide plant climbing devices capable of growing plant in three dimensions.SOLUTION: A plant climbing device 5 of the present invention has a plurality of induction pillars 53 which extends to the first direction toward which a plant climbs and is arranged along two rows parallel to each other in a second direction orthogonal to the first direction. A cultivation device 1 with high shielding effect by plant vines can be provided since plant vines can be densified without impairing plant growth by arranging the induction pillars 53 alternately in two rows.SELECTED DRAWING: Figure 1【課題】植物を立体的に育成可能な植物登攀装置を提供すること。【解決手段】本発明の植物登攀装置５は、植物が登攀する第１方向に延び、前記第１方向と直交する第２方向において互いに平行な２列に沿って配置されている複数の誘引柱５３を備える。誘引柱５３は二列に交互に配置されているので、植物の成長を損なうことなく、植物のつるを高密度化できるので、植物のつるによる遮蔽効果の高い栽培装置１を実現できる。【選択図】図１
