PROBLEM TO BE SOLVED: To compost disaster-stricken trees at site and directly reuse the compost as a vegetation base material.SOLUTION: In the slope greening method, trees that fell and slipped down due to failure of a slope 32 are used as a raw material, the raw material is crushed into a chip state by a crusher 2 to produce primary crushed chips 3, loosening treatment is performed to the primary crushed chips by a treatment apparatus 4, bacterial cells which cause microbial decomposition in treated chips 5, which were obtained immediately after the loosening treatment ended, and a nutrient material for the cells are added to the treated chips to make composting chips 6, and the composting chips are mounted and cured in a composting yard 7 to produce compost. And then, the compost is stirred and mixed by a spray machine 33 together with other vegetation base materials such as plant seeds, water, and adhesive to produce vegetation base material slurry, the vegetation base material slurry is forcibly fed to the vicinity of the slope 32 via a spray hose 34, and the slurry is then sprayed on the slope 32 via a spray nozzle 35 attached to the tip of the spray hose 34, by which vegetation foundations 36 are formed on the slope in a laminated manner.【課題】被災した樹木を現地で堆肥化しそのまま植生基材として再利用する。【解決手段】本発明に係る法面緑化方法は、法面３２の崩壊によって滑落した樹木を原材とし、該原材を破砕機２でチップ状に破砕して１次破砕チップ３を作製し、該１次破砕チップを処理装置４で膨軟化処理し、該膨軟化処理が終了した直後の処理済チップ５に該処理済チップを微生物分解する菌体とその栄養資材とを添加して堆肥化用チップ６とし、該堆肥化用チップを堆肥化ヤード７に載置して養生することにより堆肥を作製した後、かかる堆肥を、植物の種子、水、粘着剤といった他の植生基材とともに吹付機３３で攪拌混合して植生基材スラリーを作製し、該植生基材スラリーを吹付けホース３４を介して法面３２の近傍まで圧送した後、吹付けホース３４の先端に取り付けられた吹付けノズル３５を介して法面３２に吹き付けることにより、該法面に植生基盤３６を積層形成する。【選択図】 図３
