PROBLEM TO BE SOLVED: To raise many seedlings easily, in a simplified manner, efficiently without damage on roots of the seedlings.SOLUTION: Under a parent plant cultivation bed 2, plural seedling pots 7 are detachably arranged on shelves 6 for making multi-stage cultivation beds 5 for child plant, and a nutritious liquid is supplied to a medium 25 in each seedling pot 7 by a nutritious liquid tube 9, then a child plant 4 generated from a runner 3 extending from the parent plant 1 in the parent plant cultivation bed 2 is planted on each seedling pot 7, then the runner 3 and the nutritious liquid tube 9 are arranged on a constant position in the seedling pot 7 by a runner fixture 21 for raising each child plant 4 in the seedling pot 7, then, the runner 3 is cut and each child plant 4 is raised in each seedling pot 7, and the seedling pot 7 on which the child plant 4 is raised is taken out from the shelf 6 for seedling raising.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】多数の苗を、簡単かつ容易に、しかも根の損傷することなく能率よく育苗する。【解決手段】親株栽培床2の下に、棚6に複数の苗ポット7を脱着できるように並べて多段の子株用栽培床5とし、各苗ポット7の培地25には養液チューブ9で養液を供給し、親株栽培床2の親株1から延びるランナー3から発生する子株4を各苗ポット7に植え付けし、ランナー固定具21でランナー3と養液チューブ9を苗ポット7の定位置に配置して子株4を苗ポット7で生育させた後、ランナー3を切断して子株4を苗ポット7で生育し、子株4の生育した苗ポット7を棚6から取り出して育苗する。【選択図】図2
