In cultivating and weeding, it was 16～27%.\n2)Conceming the accuracy of the row-following function of tractor implements, uniformity in row spacing is important. However,in actuality, the spacing of most fields varies between rows. Differences in row spacing ranged from 7.5cm to 11.5cm in the cases of seeding and transplanting. Moreover,for cultivating and weeding, the biggest observed difference was 8,2cm. Consequently,implement damage to crops was observed.\n3)When tractor working speed was adjusted to 2m/s for seeding and transplanting, the control speed of an actuator foτ the automatic guidance system was calculated to be 6.6cm/s. The maximum control speed of the actuator must be at least 10cm/s for cultivating and weeding.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本農作業学会","subitem_publisher_language":"ja"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.4035/jsfwr.45.13","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本農作業学会","subitem_rights_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00386823","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03891763","subitem_source_identifier_type":"PISSN"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"申, 宝明","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"佐藤, 禎稔","creatorNameLang":"ja"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"今村, 城久","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Hironaka, Kazunori","creatorNameLang":"en"},{"creatorName":"弘中, 和憲","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Kishimoto, Tadashi","creatorNameLang":"en"},{"creatorName":"岸本, 正","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-30"}],"displaytype":"detail","filename":"farmworkresearch.pdf","filesize":[{"value":"871.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"farmworkresearch.pdf","url":"https://obihiro.repo.nii.ac.jp/record/758/files/farmworkresearch.pdf"},"version_id":"01a6a429-5997-4736-8a60-69cb79e2d7a1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"管理作業","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"トラクタ作業機","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"うね間","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"作物列センサ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"制御速度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"循環型農業","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"crop management","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tractor implements","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"row spacing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"crop row sensor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"control speed","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"circulation type agriculture","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"大規模畑作地帯におけるトラクタ作業機のうね合わせ作業の現状","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大規模畑作地帯におけるトラクタ作業機のうね合わせ作業の現状","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-10-21"},"publish_date":"2010-10-21","publish_status":"0","recid":"758","relation_version_is_last":true,"title":["大規模畑作地帯におけるトラクタ作業機のうね合わせ作業の現状"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-28T03:10:10.585690+00:00"}
