PROBLEM TO BE SOLVED: To provide a method for cultivating a tree by which the above-ground part of the tree is suppressed from growing.SOLUTION: The method for cultivating the tree suppresses growth of the above-ground part of the tree after planted, and comprises the following steps: (a) a step of determining the maximum height (h) to which the above-ground part of the tree is allowed to grow (b) a step of determining the maximum depth (D) of a space which is formed in the soil and in which a water-impermeable material is charged, based on the height (h) (c) a step of forming the space and placing the material in the space so that the deepest part at the inner surface of the material accounts for D and (d) a step of putting soil in the space where the material is not placed so as to plant the tree.COPYRIGHT: (C)2010,JPO&INPIT【課題】本発明は樹木の地上部の伸長を抑制する方法を提供すること。【解決手段】以下の工程を含む植樹後の樹木の地上部の伸長を抑制する方法:(a)該樹木の地上部を伸長させる最大の高さ(h)を決定する工程、(b)前記樹木を植える土壌中に設ける、難透水性の資材が設置される空間の最大の深さ(D)を、hに基づいて決定する工程、(c)前記空間を設け、当該空間に、前記資材の内表面の最深部の深さがDであるように、前記資材の設置を行う工程、および、(d)前記空間のうち、資材が存在しない部分に土壌を載置して、植樹を行う工程。【選択図】図1
