PROBLEM TO BE SOLVED: To exert a growth promotion effect of plant by nanobubble-containing water, or improve the effect more than before.SOLUTION: A plant cultivation device has: a plant body substrate a nanobubble-containing water supply source which is capable of supplying nanobubble-containing water to the plant body substrate and nanobubble-containing water droplet supply means which is capable of supplying nanobubble-containing water from the nanobubble-containing water supply source in an atomized state, in which the plant body substrate includes one or a plurality of water passing holes, and has: a plant body support part which supports the plant body a plant body substrate top part which is arranged on a front side of the plant body support part and capable of holding nanobubble-containing water and a plant body substrate bottom part which is arranged on a rear side of the plant body support part. Atomized nanobubble-containing water is suppliable from the nanobubble-containing water supply source into the plant body substrate bottom part by the nanobubble-containing water droplet supply means, and nanobubble-containing water is suppliable from the nanobubble-containing water supply source to the plant body substrate top part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】ナノバブル含有水による植物の生育促進効果を発揮させ、又は従来よりも向上させることを目的とする。【解決手段】植物体支持体と、植物体支持体にナノバブル含有水を供給可能なナノバブル含有水供給源と、ナノバブル含有水供給源からのナノバブル含有水を微細化して供給可能なナノバブル含有水滴供給手段とを有し、植物体支持体は、一つ又は複数の通水孔を含み、植物体を支持する植物体支持部と、植物体支持部の表面側に配されてナノバブル含有水を保持可能な植物体支持体上部と、植物体支持部の裏面側に配された植物体支持体下部とを有し、植物体支持体下部の内部には、微細化されたナノバブル含有水をナノバブル含有水供給源からナノバブル含有水滴供給手段により供給可能であり、植物体支持体上部には、ナノバブル含有水をナノバブル含有水供給源から供給可能である植物栽培装置である。【選択図】図1
