To provide a seedling raising holder in which a seedling medium in which seedlings being raised are fixed, is stored and attached to a cultivation pallet, which can prevent falling of whole seedling for stably supporting the seedlings being raised and prevent root entanglement of adjacent seedlings or interference of leaves.SOLUTION: The seedling raising holder is configured so that, a seedling medium 4 in which seedlings 5 being raised are fixed, is stored and attached to a cultivation pallet 2, one side of opening end parts on both end parts is larger in a diameter than the other side, the seedling raising holder being formed into a megaphone-shaped inner cylinder 11, and to whose upper side, an outer cylinder 12 is fitted in a slidable state.SELECTED DRAWING: Figure 1【課題】内部に育苗中の苗を固定する播種培地を納めて栽培パレットに装着するものとして、苗全体が倒れることを防いで育苗中の苗を安定して支保できるとともに、隣接する苗の根絡みや葉同士の干渉を防ぐことができる。【解決手段】内部に育苗中の苗５を固定する播種培地４を納めて栽培パレット２に装着するものとして、両端の開口端部のうちの一方側が他方側よりも大径なものになっているメガホン状の内筒１１であり、外筒１２を上方にスライド可能に被嵌させた。【選択図】図１
