Zusammenfassung:To provide a weed-proof sheet that has high weatherability and can be used outdoors for an extended period and that has no water permeability, has high shading, light weight and superior anti-slip.SOLUTION: A weed-proof sheet has a substrate and a shield layer on the substrate. The substrate is selected from non-woven fabric or the like. The shield layer contains particles and binders, with the average grain diameter of the particles of 35-1,400 μm, with the rate of particles having less than 150 degree angle of 60% or more, and with (A)-(D) all fulfilled. (A) The basis weight of the entire weed-proof sheet is 400-3,000 g/m2, (B) as to the shield layer, Ra, Rz, and Rv measured by stylus type roughness meter are in a prescribed range, (C) as to the weed-proof sheet, by applying JIS A1218 correspondingly, water permeability measured with the shield layer side upside is 0, and (D) as to the weed-proof sheet, the shading rate measured compliantly by JIS L1055 is 99.9% or more.SELECTED DRAWING: Figure 1 【課題】高い耐候性を有し、屋外で長期間使用でき、透水性がなく、遮光性が高く、軽量であり、防滑性に優れる、防草シートを提供すること。【解決手段】基材、及び基材上に遮蔽層を有する防草シートであって、基材は、不織布等から選ばれ、遮蔽層は、粒子及びバインダーを含み、粒子の平均粒径が35μm~1,400μmであり、150°未満の角を有する粒子の割合が60%以上であり、(A)~(D)のすべてを満たす、防草シート:(A)防草シート全体の目付が400g/m2~3,000g/m2であること、(B)遮蔽層について、触針粗さ計によって測定したRa、Rz、及びRvが所定の範囲であること、(C)防草シートについて、JIS A 1218を準用して、遮蔽層側を上側にして測定される透水性が0であること、並びに(D)防草シートについて、JIS L 1055に準拠して測定される遮光率が99.9%以上であること。【選択図】図1
