PROBLEM TO BE SOLVED: To provide a greening method using a greening sheet capable of long-term growing and easy installation of a short-leaf plant having an excellent weed-proof effect, a resistance to breakage and corrosion, an effect of conserving and promoting a landscape of local community, and a property of not disturbing traffic visual fields.SOLUTION: A weed-proof sheet with seeds used by a greening method comprises a weed-proof sheet including: a black color nonwoven fabric disabling passage of buds of plants and having water holding ability a black color plastic sheet disabling passage of water and roots and a black color nonwoven fabric having a water repellency and a root-proof property, these fabrics and sheet being piled in this order and integrally thermobonded into a single sheet, and the weed-proof sheet having countless open holes formed. The weed-proof sheet with seeds further comprises a black raschel net sheet of a mesh size of 2 mm laid under the weed-proof sheet, and a water-soluble seed sheet with seeds and fertilizer attached on the sheet itself, under the raschel net sheet, the sheets and the weed-proof sheet being integrally thermobonded into the weed-proof sheet with seeds. The weed-proof sheet with seeds is installed to the installation surface with pins having heads larger in the diameter than the pin itself, and the spaces between curbstones are sealed with a sealant, thereby enabling thick growth of a desired plant while providing weed-proof ability.COPYRIGHT: (C)2014,JPO&INPIT【課題】防草効果に優れ、破損や腐蝕がしにくく、地域景観の保全形成に効果を有し、交通視界の妨げにならない短草植物が長期間生育可能で施工が容易に行える緑化シートによる緑化工法の提供。【解決手段】植物の芽を通さず、保水性を有する黒色不織布、水と根を通さぬ黒色ポリシート、撥水性と防根性を有する黒色不織布の順に重ねて熱接着した1枚の防草シートに一定の間隔で貫通孔を無数形成したシート下面に2ミリ目合の黒色ラッセルネットシート、その下に種子と肥料が付着した水溶性種子シートを敷設し、各シートが一体化するように熱接着して一枚のシートとした種子付防草シートを設置面に固定ピンの太さより幅広の頭部を形成した大頭ピンにて打設固定し、縁石間の隙間をシーリング剤で塞ぎ、雑草防除を図り所望植物を繁茂させる種子付防草シートによる緑化工法。【選択図】図3
