PROBLEM TO BE SOLVED: To provide a seeder, a seeding set containing the seeder, and a method for seeding with the seeding set, which can seed even non-coated seeds.SOLUTION: The seeder 1 having a seeding roll 13 for dipping up the prescribed number of seeds in a seed hopper 18 with dent portions 41 formed on the outer peripheral surface for a prescribed distance and sending out the seeds on the outside, and a measuring portion 41 which is disposed on the rotation direction forward side of the seeding roll and wherein seeds S overflowed from the opening edge of the dent portion 14 are removed from the dent portion 41 with the lower end portion 45a of a wall 45 facing the rotation direction rearward side of the seedling roll. The dent portion 41 has a rear side slope portion 41b directed from the inside of the dent portion 41 to the peripheral surface of the seeding roll 13 on the rotation direction rearward side of the seeding roll. The lower end portion 45a of the wall 45 of the measuring portion 14 is obliquely disposed so that one end side of the seeding roll in the thickness direction is placed on the rotation direction rearward side of the seedling roll rather than the rear end side.COPYRIGHT: (C)2011,JPO&INPIT【課題】 非コーティング種子でも播種可能にする。【解決手段】 本発明の播種器1は、外周面に所定間隔毎に形成された凹部41にて該種子ホッパー18内の所定数の種子を汲み上げて外部に繰り出すための播種ロール13と、播種ロール回転方向前方側に設けられ、播種ロール回転方向後方側に面した壁45の下端部45aによって凹部41の開口縁から上にはみ出ている種子Sを凹部41内から取り去るための升切り部14を備えている。凹部41は、播種ロール回転方向後方側に、該凹部41の内面から播種ロール13の周面に向かう後側傾斜部41bが設けられている。升切り部14の壁45の下端部45aは、その播種ロール厚さ方向における一端側が他端側よりも前記播種ロール回転方向後方側に位置するように傾斜状に設けられている。【選択図】 図1
