PROBLEM TO BE SOLVED: To easily perform diffusing fertilization almost uniform in the right and left directions with a nozzle body in a ridge without being disturbed with surrounding soil by connecting the nozzle body of an oblong cylindrical form and a rear spreading form to the rear to the lower end of a guide body for feeding a fertilizer and forming a raised part in the center of a releasing passage in the interior of the nozzle body.SOLUTION: A spreader of a fertilizer applicator includes the cylindrical guide body 3 for feeding the fertilizer H from a fertilizer tank 2, and the nozzle body 4 connected to the lower end of the guide body 3, and inserted into the ridge U. The nozzle body 4 has the oblong cylindrical form, connected to the guide body 3 and in the rear spreading form from the front to the rear. The releasing passage 5 for diffusing the fertilizer H, and releasing the fertilizer is formed in the interior thereof, and the raised part 6 for suppressing the amount of the fertilizer H1 passing through the center, and uniformizing the amount of the released fertilizer H1 from the center of the releasing passage 5 and the amounts of the released fertilizers H2 and H3 from the lateral parts of right and left is formed in the center in the right and left directions at the bottom of the releasing passage 5.COPYRIGHT: (C)2011,JPO&INPIT【課題】肥料を供給するガイド体の下端に横長の筒形状で且つ後方末広がり形状のノズル体を接続し、このノズル体の内部における放出路の中央部に隆起部を設けることで、周囲の土に妨害されることなく畝内でノズル体による左右方向に略均等な拡散施肥を容易に行えるようにする。【解決手段】肥料タンク2からの肥料Hを供給する筒状のガイド体3と、このガイド体3の下端に接続され且つ畝U内に挿入されるノズル体4とを有している。ノズル体4は、横長の筒形状で且つガイド体3に接続された前部から後部にかけて後方末広がり形状であり、内部に肥料Hを拡散させて放出する放出路5が形成され、この放出路5の底面における左右方向の中央部には、この中央部を通る肥料H1の量を抑えて放出路5の中央部からの肥料H1の放出量と左右側部からの肥料H2、H3の放出量とを均す隆起部6が形成されている。【選択図】図1
