PROBLEM TO BE SOLVED: To provide a guiding device for plant cultivation inexpensive and reduced in working load.SOLUTION: The guiding device for plant cultivation 1 is provided with the following parts: a rail 20 which is installed at a predetermined height above a cultivation bed 10 for plants in a hothouse a runner 30 which has a supporting member 31 extending along the rail 20 and a plurality of supporting parts set up in a direction where the supporting member 31 extends in prescribed intervals and movably supporting the supporting member 31 on the rail 20 and a cord member 40 which is set up at the runner 30 and to which a guiding tool 50 is detachably attached. The rail 20 is provided with the rail member separably connected and curved toward its end part to be formed in a ring state. The cord member 40 connects the one end side and the other end side of the supporting member 31 and crosses below the supporting member 31. The rail 20 is provided with a movement regulating member regulating the movement of the supporting member 31 pulled by the self weight of the plant caught on a guiding cord 70.COPYRIGHT: (C)2007,JPO&INPIT【課題】コストが安価であり、作業負担が軽くなる植物栽培用誘引装置を提供する。【解決手段】植物栽培用誘引装置1は、温室内で植物の栽培ベッド10の上方の所定の高さに配設されたレール20と、このレール20に沿って延びる支持部材31及び支持部材31の延びる方向に所定間隔を有して配設されてレール20に対して支持部材31を移動自在に支持する複数個の支持部を有したランナ30と、ランナ30に設けられて誘引具50を着脱自在に取り付ける紐部材40とを有する。レール20は、分割可能に連結されて端部に湾曲したレール部材を配置して環状に形成される。紐部材40は、支持部材31の一端側と他端側を繋いで支持部材31の下方で交差する。レール20には、誘引紐70に係止された植物の自重によって引っ張られる支持部材31の移動を規制する移動規制部材が取り付けられる。【選択図】 図1
