Zusammenfassung: | To provide a nutritious liquid cultivation system capable of storing nutritious liquid in a cultivation bed in power failure or in operational malfunction of a pump.SOLUTION: At a steady state, nutritious liquid in a nutritious liquid tank 3 is quantitatively supplied to an upstream side of a cultivation bed 2 via a pump 4 and a piping 5. In a nutritious liquid cultivation system, nutritious liquid flown out from a downstream side of the cultivation bed 2 is returned to the nutritious liquid tank 3 via a trough member 7 and a piping 8. In power failure or in operational malfunction of the pump 4, the cultivation bed 2 tilts such that the upstream side is at a lower position and the downstream side is at a higher position, and nutritious liquid is pooled in the cultivation bed 2.SELECTED DRAWING: Figure 1
【課題】停電時やポンプの作動不全時に栽培ベッドに養液を貯留することができる養液栽培システムを提供する。【解決手段】定常時には、養液タンク3内の養液がポンプ4及び配管5を介して栽培ベッド2の上流側に定量的に供給される。栽培ベッド2の下流側から流出した養液は、樋部材7、配管8を介して養液タンク3に返送される。停電時又はポンプ4の作動不全時には、栽培ベッド2の上流側が低位となり、下流側が高位となるように傾動し、栽培ベッド2に養液が貯留される養液栽培システム。【選択図】図1 |
