PROBLEM TO BE SOLVED: To achieve proper side dressing in which a dressing furrow with a solid inner wall is formed in the location at some distance from seeds directly planted in the shape of thread (line).SOLUTION: A fertilization seeding device is configured by: idlably installing tire wheels and iron wheels at the bottom of a body pulled by a tractor connecting the rotating shaft of the tire wheels and the iron wheels with chains so that the circumferential speed of the iron wheels becomes slower than that of the tire wheels and tightening the inner wall of a dressing furrow by moving the iron wheels in a half-slipping state to thereby make it hard to fall apart. In the dressing furrow, fertilizer is dropped from a fertilization discharge port at the lower end of a fertilization hose, and is covered up with soil by using a soil-covering rake. Also, a seed floor is formed by the soil-covering rake, and seeds are dropped in the shape of thread (line) from a seeding discharge port at the lower end of a seeding hose to this floor and the seeding is performed.COPYRIGHT: (C)2015,JPO&INPIT【課題】条(すじ)状に直播した種子から一定距離はなれた場所にしっかりした内壁の施肥溝を形成して、適切な側条施肥を実現する。【解決手段】トラクタで牽引する本体の底部にタイヤ輪と鉄車輪を遊転可能に設置し、タイヤ輪と鉄車輪の回転軸を、鉄車輪の周速がタイヤ輪のそれより遅くなるようにチェーンなどで連結し、鉄車輪を半スリップ状態で移動することにより施肥溝の内壁を締め付け崩れにくくする。施肥溝には施肥ホース下端の施肥排出口より肥料を落とし土掛けレーキで覆土すると共に、土掛けレーキで種子床を形成し、これに播種ホース下端の播種排出口より種子を条(すじ)状に落として播種を行う。【選択図】図2
