To prevent a plurality of seedlings from withering by crotch opening, and facilitate dealing with cases such as witheredness of a branch and growing point loss due to another factor.SOLUTION: When getting out a plurality of branches 12 respectively having the same roots from a plurality of seedlings 28 planted in a cultivation bed 24 or a culture medium 26, all of the branches 12 having the same root are gotten out from the same seedling 28 to the same side of the cultivation bed 24, and on the other hand, all of the branches 12 having the same root are gotten out from the adjacent seedling 28 to the opposite side of the cultivation bed 24 in which four or more seedlings 28 can be planted on one cultivation bed 24 or culture medium 26.SELECTED DRAWING: Figure 4【課題】複数本仕立て苗が股割けにより枯れ死しにくく、別な要因で枝が枯れ死したり生長点がなくなったりした場合の対応を容易とする。【解決手段】栽培ベッド２４又は培地２６に植え付けられた複数本の苗２８から、それぞれの同一の根を持つ複数の枝１２を引き出す際に、同じ苗２８からは、同一の根を持つ複数の枝１２すべてを栽培ベッド２４の同じ側に引き出す一方、隣り合う苗２８からは、同一の根を持つ複数の枝１２すべてを栽培ベッド２４の反対側に引き出す。この際、１つの栽培ベッド２４又は培地２６に４本以上の苗２８を植え付けることができる。【選択図】図４
