PROBLEM TO BE SOLVED: To reduce the weight of a planting base.SOLUTION: A second net material 140 is attached to a panel material 110 in a state that a sheet material 130 and a water retaining member 120 are positioned between the second net material 140 and the panel material 110. Thereby, a planting base 100 is formed by integrating the second net material 140, the sheet material 130, the water retaining member 120 and the panel material 110. A plant 50 is planted in a housing part 150 which protrudes from a mesh 144 of the second net material 140 and is formed of the sheet material 130 and an outside water retaining member 126. The plant 50 planted in the housing part 150 is grown by entangling a root 52 in a first net material 124 of the water retaining member 120.COPYRIGHT: (C)2014,JPO&INPIT【課題】植栽基盤を軽量化する。【解決手段】第二網材140でシート材130と保水部材120とを間に挟んでパネル材110に取り付けることで、第二網材140とシート材130と保水部材120とパネル材110とが一体化された植栽基盤100となる。また、シート材130と外側保水材126とで形成され第二網材140の網目144から突出する収容部150に植物50が植栽される。収容部150に植栽された植物50は、保水部材120の第一網材124に根52を絡ませて生育する。【選択図】図1
