< Topic >At the same time simplicity it can do fix planting job and harvest job as efficiently, the whole device at the same time with simple structure the hydroponics device which can produce cheaply is offered.SolutionsAs the nursery bed palette 1 it plants containment the plant and nursery bed palette 1 it mounts supports in order to form the liquid fertilizer wraparound path which it wraps supplies the liquid fertilizer in the root of the plant containment in nursery bed palette 1, the gutter-shaped cultivation base being laid out in the upper part section of 3 which is in parallel laid out in the crosswise of the device and nursery bed palette, 1 the device itself shelf which the illuminant 4 which irradiates the light of the wavelength which makes photosynthesis the plant promote and gutter-shaped cultivation base 3 and the illuminant 4 it locks supports and, it has. The palette carrying opening section 8A which enters nursery bed palette 1 on sequential gutter-shaped cultivation base 3 is formed in the longitudinal direction one destal of gutter-shaped cultivation base 3, in order with the slide movement of nursery bed palette 1 grew to harvest the plant which in the longitudinal direction other end, the palette carrying out opening section 8B which carries out nursery bed palette 1 from on sequential gutter-shaped cultivation base 3 is formed.< Choice figure >Drawing 1【課題】定植作業及び収穫作業を簡単且つ効率よく行えると共に、装置全体を簡素な構造で且つ安価に製作することができる水耕栽培装置を提供する。【解決手段】植物を定植保持する苗床パレット1と、苗床パレット1を載置支持すると共に苗床パレット1に保持された植物の根部に液体肥料を循環供給する液体肥料循環路を形成するように装置の幅方向に並列配置された樋状栽培台3と、苗床パレット1の上方部に配置されて植物に光合成を促進させる波長の光を照射する光源4と、樋状栽培台3及び光源4を固定支持する装置本体棚と、を備える。樋状栽培台3の長手方向一端部には苗床パレット1を順次樋状栽培台3上に投入するパレット搬入口部8Aが形成され、長手方向他端部には苗床パレット1のスライド移動により成長した植物を収穫するように苗床パレット1を順次樋状栽培台3上から搬出するパレット搬出口部8Bが形成されている。【選択図】図1
