PROBLEM TO BE SOLVED: To provide a mix-grown lawn obtained by mixing natural lawn with false lawn body in which false lawn body is hardly removed even if the false lawn body is planted at a small embedding depth, and a method for establishing the mix-grown lawn.SOLUTION: A mix-grown lawn in which natural lawn and false lawn body 1 are mixed comprises a groove formed in the ground and a lawn thread body 2b buried in the groove and formed of a synthetic resin bent in the longer direction, and both ends of the lawn thread body 2b are exposed to the ground. Artificial false lawn leaves are not inserted deep into the ground and is hardly removed, and even in an existing ground in which vegetation of natural lawn exists, improvement can be conducted simply from the above directly.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】天然芝と擬似芝体とが混在する混生芝生で、擬似芝体が浅い埋め込み深さで植付けられても、脱抜しにくい混生芝生を提供するとともに、その混生芝生の造成方法を提供すること。【解決手段】天然芝と擬似芝体1を混在させた混生芝生であって、地面に形成された溝と、溝に埋設され、長手方向で折り曲げられた合成樹脂からなる芝糸体2bと、を有し芝糸体2bの両端が地上に露出している。人工の疑似芝葉を地中深く差し込むことなく脱抜しにくい疑似芝葉の差し込みが可能であり、天然芝の植生が存在する既設のグラウンドに対しても、そのまま上から簡易に改良することができる。【選択図】図1
