Abstract

水稲湛水直播において, 安定した播種深さに高い精度で播種できる, 湛水土壌中条播機の開発を行った。開発した条播機は水田用栽培管理ビークルなどに直装する, 側条施肥装置付き8条又は10条播きの播種機で, 繰出部と作溝・覆土部からなる。作溝・覆土部は追従性を向上させたフロート, 2段階に深さを調節できる作溝器及び土壌表面硬度に応じて覆土量を制御できる覆土装置等を備えている。土壌の硬軟に左右されず安定した覆土性能を発揮させるために, 覆土板形状と制御方法を検討する基礎試験を実施し, 良好な覆土性能を持つ覆土板形状, 土壌硬度を4段階に分けて覆土板角度を制御するアルゴリズムの有効性を明らかにした。

This study was carried out to develop precision direct drill Seeder with controls of seed depth for direct sowing of rice on paddy field. The developed Seeder mounted on a paddy vehicle consisted of a feeding unit and a furrow opener-closer unit. The furrow opener-closer unit was constructed with a float that follows the soil surface smoothly, a two stage adjustable furrow opener and a seeding depth controller with the soil surface hardness sensor described in Part 1. In order to clear the shape of the soil covering plate and the controlling method of the plate angle, basic rotary soil bin tests were conducted. As a result, the shape of the soil covering plate and the available controlling method of the plate angle was clarified.
