PROBLEM TO BE SOLVED: To provide an agricultural/horticultural support pillar jointing tool which when plural rod-like agricultural/horticultural support pillars are used, joints those support pillars with one another in such a manner that the degree of freedom of mounting is increased during mounting to the support pillars, and also to provide an agricultural/horticultural support pillar erecting tool which when plural agricultural/horticultural support pillars are used, erects those support pillars within an agricultural/horticultural container in such a manner that the degree of freedom of erecting the support pillars within the container is increased.SOLUTION: An agricultural/horticultural support pillar jointing tool 1 is formed of a flexibility tape-like component, and comprises a mounting hole train 1a, a cutting guide part 1b, and an adjustment mark 1c. An agricultural/horticultural support pillar erecting tool 2 uses the agricultural/horticultural support pillar jointing tool 1, and is formed of a flexibility, elongated, planar component, one end side of the component being a mounting part 2a with a mounting hole train 2c provided thereon, and the other end side of the component being an insertion part 2b to be inserted into a culture material C within an agricultural/horticultural container B.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 農園芸において用いられる棒状の農園芸用支柱を複数用いる場合にこれを相互に連結するための農園芸用支柱連結具に関し、農園芸用支柱に取り付ける際の設置の自由度を高めるとともに、農園芸用支柱を複数用いる場合にこれを農園芸用容器内に立設するための農園芸用支柱立設具に関し、農園芸用容器内に立設する際の設置の自由度を高める。【解決手段】 農園芸用支柱連結具1は、柔軟性のあるテープ状の部材によって形成されており、取付孔列1aと、切断案内部1bと、調節目印1cとが設けられている。農園芸用支柱立設具2は、農園芸用支柱連結具1を利用する農園芸用支柱立設具であり、柔軟性のある細長の平板状の部材によって形成されており、その一端側が取付孔列2cを設けた取付部2aになっているとともに、その他端側が農園芸用容器B内の培養材Cに挿入するための挿入部2bになっている。【選択図】 図1
