PROBLEM TO BE SOLVED: To solve such problems that in recent years, an environmental problem attracts much concern and protection of trees is paid attention, and so a tree doctor and a person involved in landscape architecture perform tree treatment, but corrosion after treatment progresses, and a finish after treatment aesthetically looks awful and painful.SOLUTION: A method for treating, reproducing and mending trees includes applying sterilization treatment after removing rot, restoring lost tree skin followed by finishing aesthetically, setting a vent hole on the restored tree skin, and ventilating a void part from which rot is removed so as to dry the inside and reduce the development of various germs. Furthermore, the method includes adopting an elastic fibrous foundation sheet causing no crack and gap for the restored tree, and setting a pipe or holehardly causing crack or gap, and naturally drains to the outside even when rainwater enters.COPYRIGHT: (C)2013,JPO&INPIT【課題】近年環境問題が騒がれ樹木の保護が注目され樹木医や造園関係者等が樹木治療を行っている。しかし治療後の腐食が進行したり、治療後が美観的に見苦しく痛痛しい仕上がりであったりと、まだまだ解決をしなくてはならない課題が多くあった。【解決手段】腐れを取り除いた後殺菌処理を施し、無くなった木肌を復元し美観的に仕上げ、復元木肌に通気口を設け、腐れを取った空洞部に通気し内部を乾燥させ雑菌の発生を軽減した。また復元木肌が罅や隙間が生じない弾力性のある繊維下地シートを採用し、罅や隙間が生じにくく雨水が浸入しても自然に外部に排水する管あるいは孔を設け解決手段とした。【選択図】 図1
