PROBLEM TO BE SOLVED: To provide a tool for short term raising and method for raising of plant seedlings, capable of ascertaining anytime in a plant seedling raising process of growing long length roots in a short term in a raising material in a tube body, the condition of the raising material in the tube body, and the end position of growing roots of plant seedlings to provide a plant seedling set for fix planting and to provide a seedling planting method.SOLUTION: This method for short term raising includes using the tool for short term raising which is composed of a tube main body in which a part of the aspect of a tube body is cut off in the longitudinal direction, a transparent covering material closing the cut opening part of the tube main body, and a raising material for the plant seedlings, filled in the tube main body whose opening part is closed with the transparent covering material. The raising material filled in the tube main body is adjusted in hardness enabling increase of a growth speed to a lower side of the roots of the plant seedlings to be fixed to the upper opening inside of the tube main body. The growing condition of the roots is ascertained by setting a partition wall in the tube main body and observing that the roots of the plant seedlings climb over the partition wall through the transparent covering material.COPYRIGHT: (C)2008,JPO&INPIT【課題】筒体内の育成材料中に長尺根を短期に成長させる植物苗の育成工程において、筒体内の育成材料の状態と植物苗の成長中の根の先端位置を随時に確認することのできる植物苗の短期育成用具および育成方法、定植用植物苗セット、並びに植苗方法を提供する。【解決手段】筒体の側面の一部が長手方向に切り欠かれた筒体本体と、該筒体本体の切り欠かれた開口部を塞ぐ透明蓋材と、前記透明蓋材により開口部が塞がれた筒体本体内に充填されている前記植物苗用の育成材料とを有してなり、前記筒体本体内に充填されている育成材料が、前記筒体本体の上部開口部内側に固定する植物苗の根の下方への成長速度を増大させることを可能にする硬度に調整されてなる短期育成用具を用いる。前記筒体本体内に仕切壁を設け、この仕切壁を植物苗の根が乗り越えていることを前記透明蓋材を通して観察して根の成長状態を確認する。【選択図】 図1
