PROBLEM TO BE SOLVED: To provide a wall surface greening system that improves soil of wall surface greening, prevents water leakage from soil, suppresses natural evaporation of water, promotes water retention enough for cultivation, prevents water filtration except watering such as rainwater, achieves cultivation of plants and simplification of control by planned watering with less water and does not need installation of water receiving for receiving water leakage from soil connected to cost increase of installation and to dominantly install wall surface greening.SOLUTION: Furrows are formed in conventional solid soil, the whole solid soil with the furrows is packed with a waterproof packing material and the packed state is regarded as solid soil for wall surface greening. The wall surface greening system does not cause water in the wall surface greening to flow outside and prevents water filtration from the outside so as to perform planned watering with a reduced amount of watering and not to require water receiving of water outflow countermeasures to the outside of soil.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明は壁面緑化の土壌を改良し、土壌からの水漏れを防ぎ、さらに水の自然蒸発を抑制し、育成に十分な保水を促し、雨水等の灌水以外からの水の浸入を防いで、少ない水での計画的な灌水による植物の育成と管理の簡便化を実現しようとするものであり、又、設置のコストアップにつながる土壌からの水の漏れを受ける水受けの設置を必要としない壁面緑化システムを提供し、壁面緑化の設置を優位にしようとするものである【解決手段】 従来の固形土壌に溝等を形成し、溝付きの固形土壌全体を防水梱包生地で梱包し、梱包した状態を壁面緑化用固形土壌とする。壁面緑化内の水を外に流失させず、又外部からの水の浸入を防ぐ事によって、灌水の量を減らした計画的な灌水と、土壌外へ水の流失対策の水受けのいらない壁面緑化システムを提供する【選択図】図2
