PROBLEM TO BE SOLVED: To improve an application effect by running chemicals sprayed simultaneously to be distributed over the entire cross section of ridge parts when partially tilting and fertilizing.SOLUTION: In the ridging fertilizer applicator, a tilting rotary 6 and a ridge forming device 7 for forming ridges by accepting tilted soil are installed in the rear side of a tractor body 1, a plurality of tilting claws 23, 23... and a pair of disks 25, 25 corresponding to an interval of ridge widths of the ridges formed by the ridge forming device 7 are arranged in a tilting shaft 15 of the tilting rotary 6, a delivery unit H for delivering a granular powder material is provided, and the power granular power material delivered between or in front of the opposing disks 25, 25 is stirred together with the soil. The ridging fertilizer application includes a spreader K for spreading the granular power material corresponding to the substantial entire width of the ridges formed by the ridge forming device 7.COPYRIGHT: (C)2013,JPO&INPIT【課題】 部分耕耘施肥において、同時に散布する薬剤を畝立部断面全体に分布すべく行き渡らせて施用効果を高めようとする。【解決手段】トラクタ車体1の後方に耕耘ロータリ6と耕耘土壌を受けて畝成形する畝成形器7を装着し、耕耘ロータリ6の耕耘軸15には複数の耕耘爪23,23…と畝成形器7で成形する畝の畝幅間で対応する対のディスク25,25を配設し、粉粒状物を繰り出す繰出手段Hを設け、対向するディスク25,25間またはその前方において繰り出された粉粒状物を土壌と共に攪拌する畝立施肥装置において、前記畝成形器7による畝の略全幅に相当して粉粒状物を拡散する拡散手段Kを設ける。【選択図】 図6
