Problem to be solved: to provide a cultivation system in which a plurality of trays to be delivered and delivered to a multi-stage type shelf are connected and unloaded by a connection and releasing at a desired position by one feeding device, and the empty tray after harvest is accommodated in a compact manner.A plurality of moving trays 3 are carried in and out into a multi-stage type shelf 1, and the cultivation container 2 is placed on the tray 3.The individual trays 3 are detachably connected to each other by an adjacent tray 3.The cultivation shelf 1 is provided with a plurality of steps including a cultivation lane a into which a tray 3 on which a culture vessel 2 is placed is carried in and a storage lane B into which an empty tray 3 (k) in which the cultivation vessel 2 is removed is carried out just below the cultivation Lane A is provided in one stage.The vertical movement of the elevating portion 6 of the supply device 5 adjacent to one side of the shelf 1 causes the tray 3 to be connected to and disconnected from the tray train, and the tray 3 is fed into the desired cultivation Lane A or the storage lane B.Diagram【課題】多段式栽培棚に搬出入する複数のトレーの所望位置での連結と解除による搬出入を一つの供給装置だけで行い、収穫後の空トレーはコンパクトに収容する栽培システムを提供する。【解決手段】移動自在な複数のトレー３が多段式の栽培棚１に搬出入され、トレー３に栽培容器２を載置して栽培する。個々のトレー３は隣接するトレー３同士で着脱自在に複数連結される。栽培棚１には、栽培容器２が載置されたトレー３が搬出入される栽培レーンＡと、栽培容器２が取り去られた空トレー３（Ｋ）が栽培レーンＡの直下位置で搬出入されるストレージレーンＢとが一対で１段とされ複数段設けられている。栽培棚１の一側面に隣接された供給装置５の昇降部６の上下動により、トレー３がトレー列に対し連結及び連結解除が行われ、トレー３が所望の栽培レーンＡ又はストレージレーンＢに搬出入される。【選択図】図３
