PROBLEM TO BE SOLVED: To provide construction methods using humus and fulvic acid as a construction method for planting trees in the face of slope.SOLUTION: Supplying a fertilizer to a plant over a long period of time becomes possible by enclosing or attaching into a degradable or non-degradable vegetation mat or sheet humus and fulvic acid which are produced by soaking a proper amount of undegraded organic substance of a tree, grass, vegetable debris, or litter into wood vinegar or bamboo vinegar which are produced in a charcoal production process and are very strong acid organic acid, and by caring for a long period of time, so as to enhance the photosynthetic activity of a plant and to promote the growth, and also to promote long-term granulation of a vegetation base. Expecting animal evasion effect such as deer which dislikes the odors of smoking of humus and fulvic acid becomes also possible.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】のり面を緑化する工法として腐植とフルボ酸を用いた工法を提供する。【解決手段】木又は草又は野菜屑又は落葉落枝の未分解の有機物を炭の製造過程で産出される極強酸性の有機酸である木酢液又は竹酢液に適量漬け込み,長期間養生することで製造される腐植とフルボ酸を分解,非分解性の植生マット,シートの中に封入又は張り付けることによって植物の光合成の活性を高めて生育を促進し,また植生基盤の長期的な団粒化を促すことによって長期的に植物へ肥料分を供給できることを可能とした。また腐植とフルボ酸の燻製の臭いを嫌うシカ等の忌避効果を期待することを可能とした。【選択図】図1
