PROBLEM TO BE SOLVED: To provide a construction method at a low cost for intentionally introducing woody plants at a place having comparatively excellent vegetation conditions from the beginning of the execution of works by sowing. SOLUTION: Open and closed cell structure is formed to the surface layer section of a ground to be greened. The porous vegetation bedrock 4 can be prepared by applying a spraying agent consisting of a membrane forming agent as a membrane component after spraying and a foaming agent for imparting cellular structure to the membrane forming agent to the surface layer of the ground to be greened. To be concrete, the membrane forming agent and the foaming agent are prepared in separate tank respectively, and force-fed by a separate pump and sprayed while being mixed in a spray nozzle, thus preparing the porous vegetation bedrock 4. The membrane forming agent and the foaming agent may be sprayed simultaneously and separately, or the membrane forming agent and the foaming agent may also be sprayed in either order. |
