PROBLEM TO BE SOLVED: To provide an agricultural mulch material equipped with high water passing efficiency while suppressing evaporation of moisture and overgrowth of weeds.SOLUTION: In an agricultural mulch material in which a plurality of water passing parts 14 for allowing water to pass through to front/rear are formed, the water passing part 14 has a first slit group that is composed of an aggregation of a plurality of linear slits 141 radially arranged from the center with a distance, the central part of the water passing part is a non-water passing region in which the slits are not arranged, and preferably 5 to 8 slits 141 are radially arranged in the first slit group.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】水分の蒸発及び雑草の繁茂を抑えながらも、高い通水効率を備えた農業用マルチ資材を提供すること。【解決手段】水を表裏に通過させる複数の通水部14が形成された農業用マルチ資材において、前記通水部14は、中心から距離をおいて放射状に配置された複数本の直線状のスリット141の集合からなる第1のスリット群を有し、通水部の中心部は前記スリットが配置されない非通水領域であり、好ましくは、前記第1のスリット群は、5本~8本の前記スリット141が放射状に配置されている農業用マルチ資材。【選択図】図3
