PROBLEM TO BE SOLVED: To provide a plant protection material capable of reducing counter pressure from protrusions even when not made of elastomer, but of the same material as a lower plant protection material.SOLUTION: A plant protection material has an upper and lower two-layer structure for protecting plants from tread pressure by people and vehicles. A lower plant protection material includes lower tread pressure parts and lower hole-penetrating parts the lower tread pressure parts are composed of a plurality of protrusions connected together at a certain interval the lower hole-penetrating parts are spaces surrounded by the protrusions and connection hole parts for connecting the protrusions to an upper plant protection material are provided on the tops of the protrusions comprising the lower tread pressure parts. The upper plant protection material includes upper tread pressure parts and upper hole-penetrating parts the upper tread pressure parts are composed of face-down dish-shaped parts covering and connecting to the protrusions which comprise the lower tread pressure parts the upper hole-penetrating parts are spaces surrounded by the face-down dish-shaped parts and claw parts are disposed at the lower portions of the face-down dish-shaped parts. This way, the plant protection material has the upper and lower two-layer structure where the claw parts are connected to the connection hole parts provided on the tops of the protrusions.COPYRIGHT: (C)2015,JPO&INPIT【課題】本発明は、エラストマー製でなく、下部植物保護材と同じ材質でも突状部からの反圧を軽減する植物保護材の提供を目的とする。【解決手段】本発明は、人や車の踏圧から植物を保護する上下2層構造からなる植物保護材であって、下部植物保護材は下部踏圧部と下部透水部からなり、下部踏圧部は間隔を隔て連結された複数の突状部から構成され、下部透水部は前記突状部で囲まれた空間であり、かつ下部踏圧部を構成する突状部の頂点には上部植物保護材を連結するための連結孔部が設けられ、上部植物保護材は、上部踏圧部と上部透水部とから構成され、上部踏圧部は下部踏圧部を構成する各突状部を覆う、連結した伏皿状部から構成され、上部透水部は伏皿状部で囲まれた空間であり、伏皿状部下部に爪部が設けられ、当該爪部が突状部の頂部に設けられた連結孔部に連結する上下2層構造からなる植物保護材である。【選択図】図1
