PROBLEM TO BE SOLVED: To provide a light-weight plant cultivation bed suitable for plants which can grow even with a small amount of water, and to provide a plant cultivation method excellent in ascertainment of growth conditions in mass production of the plants in the plant cultivation bed.SOLUTION: The plant cultivation bed is produced by releasably laminating a first light-shielding sheet 4 having root permeability on the surface of a support net 3 and letting the plant roots entwine to support the periphery of the support net by a frame 2. A water-holding mat 6 is laminated on the back surface of the support net. A second light-shielding sheet 5 is laminated between the support net and the water-holding mat, and a third light-shielding sheet 7 is laminated on the back surface of the water-holding mat. The plants are moss plants. The plant cultivation method includes laying down the plant cultivation bed to grow the plants, and setting up the plant cultivation bed after the plant roots entwine the support net to grow the plant. After the plant roots entwine the support net, the two plant cultivation beds are integrated with the roots of the plants facing each other and also set up to grow the plants.COPYRIGHT: (C)2010,JPO&INPIT【課題】少量の水でも生育できる植物に適した軽量な植物用栽培床の提供。この植物用栽培床で植物を大量生産する場合に生育状況の確認に優れた栽培方法の提供。【解決手段】透根性を兼備した第一遮光シート4を、植物の根をからませる支持ネット3の表面に剥離可能に積層し、支持ネットの周囲を枠体2で支持する植物用栽培床。支持ネットの裏面に保水マット6を積層する。支持ネットと保水マットの間に第二遮光シート5を、保水マットの裏面に第三遮光シート7を積層する。植物がコケ植物である。植物用栽培床を横に寝かして植物を育成し、植物の根が支持ネットに絡んだ後に植物用栽培床を立てて植物を育成する植物栽培方法。植物の根が支持ネットに絡んだ後に、二枚の植物用栽培床をその根が向かい合う状態で一体化し且つ立てて植物を育成する。【選択図】 図1
