PROBLEM TO BE SOLVED: To provide a greening system constantly and simultaneously supplying water to woody fiber plates 2 of a plurality of greening boards 1, 1, ..., by a simple irrigation system, even in a state carrying a plurality of greening boards 1.SOLUTION: The greening boards 1 each comprises a woody fiber plate 2 with a pipe groove 4 formed on the back and an irrigation pipe 7 for supplying water to the inside of the woody fiber plate 2, housed in the pipe groove 4 on the back of the woody fiber plate 2, which is provided with junctions 8, 9 on both ends. Adjacent ones of the greening board 1 can be connected to each other by connecting junctions 8, 9 of the ends of the irrigation pipe 7 with the junctions 8, 9 on both ends of the irrigation pipe 7 of the adjacent greening boards 1, and consequently greening boards 1, 1, ..., can be both connected to each other in a state maintaining water flowing condition.COPYRIGHT: (C)2013,JPO&INPIT【課題】複数の緑化ボード1,1,…を設置面上に載置した状態でも、簡単な潅水システムで、複数の緑化ボード1,1,…の木質繊維板2に対し同時に定常的に給水できるようにする。【解決手段】緑化ボード1は、裏面にパイプ溝4が形成された木質繊維板2と、この木質繊維板2裏面のパイプ溝4内に収容されかつ両端部に接続部8,9が設けられ、木質繊維板2内に給水するための潅水パイプ7とを備えたものとする。この潅水パイプ7端部の接続部8,9を隣り合う緑化ボード1の潅水パイプ7端部の接続部9,8と接続することで、両緑化ボード1,1,…同士を通水状態で連結可能とする。【選択図】図7
