PROBLEM TO BE SOLVED: To provide planting beds and hydroponic cultivation systems that can harvest cultivated plants extremely efficiently, which facilitates maintenance, inspection and cleaning.SOLUTION: A planting bed 1 is used for NFT type hydroponic culture and comprises: an elongated gutter shaped bed body 2 having an upper opening and through which a culture solution S flows； and a lid member 3 which has a planting hole 23 for holding the cultivated plants Q, covers the top opening of the bed body 2, and is movably supported at the edge of the top opening of the bed body 2 in the longitudinal direction of the main body (arrow D). In addition, the hydroponic cultivation system 13 includes a greenhouse, the planting bed 1, a trestle part 33 installed in the greenhouse to place the planting bed 1, a liquid tank 34 storing the culture liquid S, a liquid supply portion 35 for supplying the culture solution S from the liquid tank 34 to one end portion of the bed body 2 of the planting bed 1, and a returning portion 36 for returning the culture solution S flowing out from the other end portion of the bed main body 2 to the liquid tank 34.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】栽培植物の収穫を極めて効率よく行なうことができ、保守点検掃除が容易である植栽ベッドおよび水耕栽培システムが望まれている。【解決手段】植栽ベッド１はＮＦＴ式水耕栽培に用いられるものであって、上面開口を有していて培養液Ｓを流す長尺樋状のベッド本体２と、栽培植物Ｑを保持する植栽孔２３を有していてベッド本体２の上面開口を蓋止する蓋部材３と、から成るものであって、ベッド本体２における上面開口の縁部に、蓋部材３が本体長手方向（矢印Ｄ）に移動自在に支持されている。また、水耕栽培システム１３は、温室と、植栽ベッド１と、温室内に設置されていて植栽ベッド１を載せる架台部３３と、培養液Ｓを貯留した液槽３４と、液槽３４の培養液Ｓを植栽ベッド１のベッド本体２の一端部に供給する給液部３５と、ベッド本体２の他端部から流出した培養液Ｓを液槽３４に戻す返液部３６と、を備えている。【選択図】図９
