PROBLEM TO BE SOLVED: To provide a fertilizer applicator which can effectively perform an additional fertilizing operation, while reducing work load caused on the agricultural workers half-sitting posture.SOLUTION: A fertilizer applicator of the present invention includes: a body pipe 11 a tip conical portion 19 projecting from a lower edge of the body pipe 11 and movable in a vertical direction a manual operation handle 17 formed on an upper edge of the body pipe 11 a fertilizer tank 16 of a powder fertilizer 51 provided on the body pipe 19 a fertilizer pipe 13 connected to the fertilizer tank 16 and a fertilizer amount adjusting valve 12 for adjusting an amount of the powder fertilizer which passes the fertilizer pipe 13. A gap 34 is formed between the tip conical portion 19 and the body pipe 11 through which the powder fertilizer 51 passes by the operation of the manual operation handle 17, and at the same time, the amount of the powder fertilizer is adjusted by the fertilizer amount adjusting valve 12. An necessary amount of the powder fertilizer 51 is applied through the gap 34 between the tip conical portion 19 and the body pipe 11 on a surface of an additional fertilizer conical hole 61 formed by the tip conical portion 19.COPYRIGHT: (C)2015,JPO&INPIT【課題】農業従事者の中腰に係る作業負担を軽減することができ、追肥作業を効率的に行うことができる施肥装置を提供する。【解決手段】本体パイプ11と、本体パイプ11の下端から突出し上下方向に移動可能な先端円錐部19と、本体パイプ11の上端に形成された手動操作ハンドル17と、本体パイプ19に取り付けられた粉末肥料51の肥料タンク16と、肥料タンク16に接続された肥料パイプ13と、肥料パイプ13を通過する粉末肥料の施肥量を調節する流量調節弁12を備えており、手動操作ハンドル17の操作により先端円錐部19と本体パイプ11との間に粉末肥料51が通過する間隙34が形成され、同時に、流量調節弁12による粉末肥料の施肥量の調節が行われて、先端円錐部19により形成される追肥用円錐穴61の表面に先端円錐部19と本体パイプ11との間の間隙34を介して必要量の粉末肥料51が施肥される。【選択図】図1
