To provide a bacteria scraping tool for mushroom cultivation capable of performing properly and efficiently a bacteria scraping work in mushroom cultivation in a vessel so as to properly form a germination surface where a hymenocarp can be easily cut into an individually separated state in harvesting.SOLUTION: A bacteria scraping tool comprises: a shaft-shaped base part 31； a laterally protruded base part 32 provided on a tip of the shaft-shaped base part 31； and a plurality of bacteria scraping blade parts 33 which are formed into a protrusion shape in a scraping blade-shape from the laterally protruded base part 32 to a tip side, and which are provided in a lateral direction on the laterally protruded base part 32 at a prescribed interval. In right/left sides of the laterally protruded base part 32 with the rotary shaft center as a center, bending directions of tip parts of the bacteria scraping blade parts 33 become opposite each other, by bending, so that tip parts of all the bacteria scraping blade parts 33 are directed to a rotary direction of a rotary drive shaft 40, and out of the plurality of bacteria scraping blade parts 33, a tip of the outermost bacteria scraping blade part 33 which is separated by a largest distance from the rotary shaft center, is protruded by a largest length relative to other bacteria scraping blade parts 33.SELECTED DRAWING: Figure 1【課題】キノコの瓶栽培における菌掻き作業を、子実体を収穫の際に個々に分離した状態にカットし易くできるように生長させる発芽面を適切に形成するように、適切且つ効率良く行うことができるキノコ栽培用の菌掻き具を提供する。【解決手段】軸状基部３１と、該軸状基部３１の先端に設けられた横張り基部３２と、該横張り基部３２から先端側へ掻き刃状に突起した形状に設けられると共に、該横張り基部３２に左右に所要の間隔を置いて設けられた複数の菌掻き刃部３３とを備え、全ての菌掻き刃部３３の先端が回転駆動軸４０の回転方向を向くように、前記回転軸心を中心にして横張り基部３２の左右で、菌掻き刃部３３の先端の曲げ方向が反対となるように屈曲されて設けられ、複数の前記菌掻き刃部３３のうち前記回転軸心から最も離れた位置の最外位置の菌掻き刃部３３の先端が、他の菌掻き刃部３３よりも大きく突起している。【選択図】図１
