Problem to be solved: to provide a fertilizing apparatus for efficiently fertilizing topdressing in multi cultivation.A perforation part for inserting a fertilizer input port 1 and a tube part 2 for transporting the fertilizer, and inserting the cylindrical part 2 into the soil with a hole in the multi filmAn opening 4 is provided to prevent the soil from entering into the perforated portionThe perforation was cut to the extent that it could be inserted into the soil.The opening and closing lid 4 is used when the fertiliser is opened from the soil and is openedThe opening and closing lid 4 is raised when the perforation is raised, and fertilizers are fertilized in the soil.Work is simplified andAnd, it is possible to prevent the falling of fertilizer because fertilizer is put into the soil.Diagram【課題】マルチ栽培における追肥の施肥を効率的に行う施肥器具を提供する。【解決手段】肥料投入口1と肥料を移送させる筒状部2とマルチフィルムに穴を開け土壌に筒状部2を埋入させる穿孔部、および穿孔部に土壌が侵入することを防ぐ開閉蓋4を備え、穿孔部は土壌に挿入できる程度に鋭利にして、開閉蓋4は施肥器具を土壌中から引き上げた際に開く構造とした時に、穿孔部を引き上げると開閉蓋4が開き肥料が土壌中に施肥されることで、作業が簡便化し、また肥料が土壌中に投入されるため肥料の流亡を防ぐことができる。【選択図】図2
