The present invention set for nursery transplants that can achieve low-cost production of vegetables such as green onion It provides the pot body. A seedling raising chamber 1a having an opening of rectangular cross section with top and bottom is open is more, be a plastic collection bowl body 1 which is provided continuously in one direction through the respective partition walls 1b, the set Hachi-tai is the length substantially the same length in the longitudinal direction of the inner side of the nursery box 2 having a rectangular frame, be a lateral length substantially integer fraction of one of the width of the inner side of the nursery box , the magnitude of the friction between the inner peripheral surface and the interior of the seedlings of the nursery room and allowed remain seedlings in nursery room during seedling, a degree to which the time of implantation does not interfere with the withdrawal of the seedlings. Germination were seeded in each nursery room, was allowed to nursery, if you grow to a certain length, from the nursery box, was taken out one by one set pot body, further transplanted withdrawn seedlings from each nursery room. Since the set Hachi-tai is made of plastic, it can repeat use.BACKGROUND 3【課題】小ネギ等の蔬菜の低コスト生産を実現することのできる育苗移植用集合鉢体を提供する。【解決手段】上下が開放した断面四角形の開口を有する育苗室1aが複数、それぞれ区画壁1bを介して一方向に連設されたプラスチック製の集合鉢体1であって、この集合鉢体は、方形の枠を有する育苗箱2の内辺の縦方向の長さと略同じ長さであり、育苗箱の内辺の横方向の長さの略整数分の一の幅であり、育苗室の内周面と内部の苗との間の摩擦の大きさが、育苗時には育苗室内に苗を留まらせ、移植時には苗の引き抜きの障害とならない程度とする。各育苗室に播種して発芽、育苗させ、一定の長さに生長したら、育苗箱から、集合鉢体を1つずつ取り出し、さらに各育苗室から苗を抜き取って移植する。集合鉢体はプラスチック製であるので、繰り返し使用できる。【選択図】図3
