To provide a hydroponic cultivation system with excellent durability which is able to transport nursery beds with a simple mechanism.SOLUTION: This hydroponic cultivation system has a plurality of nursery beds, a hanging part, and a transportation mechanism. The plurality of nursery beds has a plurality of seedlings of the plant to be cultivated transplanted to the lateral side thereof. The hanging part hangs each nursery bed such that the plurality of nursery beds are in a state aligned in a predetermined horizontal direction from the planted side of the seedlings toward the harvesting side. The transportation mechanism transports the plurality of nursery beds in the predetermined horizontal direction such that a gap between each nursery bed in the predetermined horizontal direction is widened stepwise or continuously.SELECTED DRAWING: Figure 9【課題】簡素な機構により苗床を搬送できるとともに耐久性に優れた水耕栽培システムを提供すること。【解決手段】水耕栽培システムは、複数の苗床と、吊持部と、搬送機構とを有する。複数の苗床は、栽培対象の植物の複数の苗が側面に移植されたものである。吊持部は、上記複数の苗床が、上記苗の定植側から収穫側へ向かう所定の水平方向に配列された状態で当該各苗床を吊持する。上記搬送機構は、上記複数の苗床を、上記所定の水平方向における各苗床の間隔を、段階的または連続的に拡げながら当該所定の水平方向へ搬送する。【選択図】図９
