従来、野菜移植機によって、苗を植付ける場合、その前工程で圃場面に施肥をして、その肥料を耕耘装置によって土中に混入する技術が開発され、公開されているが、その肥料による肥効を効果的に高める目的で、畝の苗植付け幅内、成育に伴って根の張る範囲に肥料を混入して作物に適確に吸収させ、肥料の無駄を少なくする技術が開発されている。   Conventionally, when planting seedlings with a vegetable transplanter, a technique for fertilizing the field scene in the previous process and mixing the fertilizer into the soil with a tillage device has been developed and published. In order to effectively increase the fertilization effect, a technology has been developed to reduce the waste of fertilizer by mixing the fertilizer in the range where the seedlings are planted and within the range where the roots grow as the plant grows so that it can be absorbed properly by the crop. Yes.

例えば、特許第3806735号特許公報に示されている公開技術の特徴として、つぎの通り開示されている。
一つには、水平方向に延びる耕耘ロータリと、この耕耘ロータリの後方に設けられ、耕耘ロータリにより耕耘された土壌を畝に成形する対をなす畝成形板とを備え、前記耕耘ロータリのロータリ軸に、一対の前記畝成形板に対応して一対の円盤を装着し、この一対の円盤間に、肥料や農薬が繰り出される排出管を臨ませ、前記一対の円盤間に、耕耘ロータリの耕耘爪を介在させ、円盤間に排出された肥料や農薬を土壌と攪拌し、前記一対の円盤間に形成される攪拌領域が前記一対の畝成形板間に形成される畝高さを有する畝の畝幅中央になるように、前記畝成形板に対して前記円盤を配置したことを特徴とする。また一つには、前述した特徴に加えて、前記円盤の直径を、耕耘ロータリの回転外周の径より大きくしたことを特徴とする。
と記載されている。
For example, as a feature of the disclosed technique disclosed in Japanese Patent No. 3806735, it is disclosed as follows.
One is provided with a tilling rotary extending in the horizontal direction and a pair of trough forming plates which are provided behind the tilling rotary and which mold the soil plowed by the tilling rotary into a trough, and the rotary shaft of the tilling rotary A pair of disks corresponding to the pair of ridge-forming plates, and a discharge pipe through which fertilizer and agrochemical are fed are faced between the pair of disks, and a cultivating claw of a cultivating rotary is disposed between the pair of disks. And the fertilizer and pesticide discharged between the disks are stirred with the soil, and the stirring area formed between the pair of disks has the height of the paddle formed between the pair of paddle forming plates The disk is arranged with respect to the bowl forming plate so as to be in the center of the width. In addition, in addition to the above-described features, the diameter of the disk is larger than the diameter of the rotary outer periphery of the tillage rotary.
It is described.

上述のように、従来、公知となっている技術は、植付け作業の前工程として行われる施肥、耕耘の作業において、土中に混入された肥料の無駄を極力少なくして、次工程で行なわれる植付け作業で圃場に挿植された苗に対して肥効を高め、根に効率よく吸収させることをねらった技術である。   As described above, conventionally known techniques are performed in the next process while minimizing the waste of fertilizer mixed in the soil in the fertilization and tilling work performed as a pre-process of planting work. This technique aims to increase the fertilization effect on seedlings planted in the field by planting work and efficiently absorb them into the roots.

特許第3806735号特許公報Japanese Patent No. 3806735
