PROBLEM TO BE SOLVED: To attain greening by a specific plant while inhibiting growth of other plants.SOLUTION: The greening construction method comprises: a weed-proof soil layer forming step for forming a weed-proof soil layer having a predetermined thickness on a surface to be constructed by using a weed-proof soil with which plants hardly grow as compared to soil under the surface to be constructed a through-hole forming step for forming a through-hole to the formed weed-proof soil layer and a pot inserting step for closing the formed through-hole by inserting a pot seedling at least the surface soil of which is covered with weed-proof soil. In the weed-proof soil layer forming step, a weed-proof soil layer is formed by making soil in which a lime component is mixed and pH is adjusted to 7-12 as the weed-proof soil, and in the pot inserting step, a pot seedling in which a seedling of a plant capable of growing in soil at pH 7-12 is planted, is inserted to the through-hole.COPYRIGHT: (C)2016,JPO&INPIT【課題】 他の植物の繁茂を抑えながら特定の植物で緑化する。【解決手段】 緑化工事方法は、被施工面下の土壌よりも植物が生育しにくい防草土を用いて、被施工面に既定の厚さの防草土層を形成する防草土層形成ステップと、形成された防草土層に、貫通口を形成する貫通口形成ステップと、少なくとも表土が防草土で覆われたポット苗を挿入して、形成された前記貫通口を塞ぐポット挿入ステップとを有する。防草土層形成ステップにおいて、石灰成分が混合されて、pHが7~12に調整された土を前記防草土として、防草土層を形成し、ポット挿入ステップにおいて、pH7~12の土壌において生育可能な植物の苗が植えられたポット苗を前記貫通口に挿入する。【選択図】図2
