PROBLEM TO BE SOLVED: To provide a method and an apparatus of one-step dense planting of tomato that can reduce the invitation/skiffing operation that needs a lot of working hours in the one-step dense planting.SOLUTION: A cultivation tank 10 that is continuously disposed along the longitudinal direction is provided. Two or more invitation lines 20 that are horizontally disposed on the cultivation tank 10 are provided. A load pipe 30 disposed in parallel to the invitation lines above the west side surface of the cultivation tank 10 is provided. An invitation clip 40 that fixes a main stem P2 to the load pipe 30 is provided. The development leaf P4 of a growing minor P3 is put on each of the invitation lines 20. At a specified time, the main stem P2 that is inclined to the west side from the transplant position of the cultivation tank 10 is fixed to the load pipe 30 through the invitation clip 40.COPYRIGHT: (C)2013,JPO&INPIT【課題】一段密植栽培において、多くの労働時間を必要とする誘引・整枝作業の軽減を図ることが可能なトマトの一段密植栽培方法及び装置を提供する。【解決手段】長手方向に沿って連設される栽培槽10を設ける。栽培槽10の上に水平に設置される複数本の誘引線20を設ける。栽培槽10の西がわ側面上方で誘引線と平行に設置された荷重負担パイプ30を設ける。該荷重負担パイプ30に主茎P2を固定する誘引クリップ40を設ける。生育した枝葉P3の展開葉P4を各誘引線20に載せる。特定時期に、栽培槽10の定植位置から西がわに傾けた主茎P2を、誘引クリップ40を介して荷重負担パイプ30に固定する。【選択図】 図1
