PROBLEM TO BE SOLVED: To provide a mulching device for a planted tree suppressing growth of weeds around the root of a planted tree, specifically a planted fruit tree, simplifying application of fertilizer, medicaments and the like, and also repelling insects and/or birds.SOLUTION: The mulching device for a planted tree comprises a plurality of fan-shaped mulching pieces, and is structured as follows: the fan-shaped mulching pieces are developed centering around the root of the tree so as to be formed into an annular mulching when used and are superimposed so as to be formed into one assembled set of the fan-shaped mulching pieces when stored each of the fan-shaped mulching pieces internally has a fan-shaped cartridge whose inner space formed by the body and longitudinal walls thereof is charged with medicaments and/or fertilizer a plurality of supports upstanding from the fan-shaped mulching pieces are set up a net-receiving top ring is placed on the top parts of the supports and an insect/bird repelling net is hung over the outside of the net-receiving top ring and the group of the supports.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明は、植栽樹木、特に植栽果樹の根元周りにおいて、雑草の発生抑制を図るとともに、肥料、薬剤等の施肥を簡易化して実施でき、また防虫・防鳥も可能なマルチング装置を提供する。【解決手段】マルチング装置が複数の扇形状マルチング片から構成されており、使用する時には樹木の根元を中心に扇形状マルチング片を展開して円環状マルチングを形成し、格納する際には重ね合せて一つの扇形状マルチング片集合体を形成する構成にし、また扇形状マルチング片が、本体と縦壁から形成される内部空間に薬剤・肥料を充填した扇形状のカートリッジを内蔵し、また扇形状マルチング片から立設する複数本の支柱を設けると共に支柱の上端部にネット受け上部リングを配設し、ネット受け上部リングと支柱群の外側に防虫・防鳥ネットを掛ける構成にしたことを特徴とする。【選択図】図1
