Direct sowing of rice in well dried paddy fields is expected to reduce farmers’ workload in spring and enable upland crop cultivation for lowland crop rotation.\nFor stable emergence, ground leveling is important in the process of cultivation. Ground leveling is required yearly as fields may change their levels. To reduce the workload of leveling in the subsequent spring season, we propose ground leveling for direct sowing of rice in well dried paddy fields to be performed after wheat harvesting in prior year. Doing so is estimated to reduce time spent on farming operations by 30% as compared to the conventional leveling method. Moreover, with better understanding of fields’ surface condition and the use of field maps, the operation time is shortened by 50%.","subitem_description_type":"Abstract"},{"subitem_description":"北海道の水田輪作体系では，栽培期間の制約から耕起・播種・育苗・移植などの作業を春先の非常に短い期間に行わねばならず，このことが規模拡大の制約となっている。このため，育苗等の手間が省け，畑作物との相性も良い水稲乾田直播栽培に期待が寄せられている。しかし，乾田直播栽培での安定した発芽のためには田面の均平が重要であり，圃場によっては毎回均平作業が必要となる。そこで，春の均平作業の軽減を図り，秋まき小麦収穫後に整地する前年整地体系での春作業の軽減効果を明らかにした。その結果，前年整地の導入により，慣行体系に比べ春の整地作業時間(耕起と均平） を3I弱削減でき，さらに圃場の高低差マップにより作業者が事前に圃場の凹凸を把握できれば，慣 行体系に比べ5I弱削減できると考えられた。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002277","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002277","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-8073","subitem_source_identifier_type":"ISSN"}]},"item_10002_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":"長南, 友也"},{"creatorName":"チョウナン, ユウヤ","creatorNameLang":"ja-Kana"},{"creatorName":"CHONAN, Yuya","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"吉田, 晋一"},{"creatorName":"ヨシダ, シンイチ","creatorNameLang":"ja-Kana"},{"creatorName":"YOSHIDA, Shimichi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"村上, 則幸"},{"creatorName":"ムラカミ, ノリユキ","creatorNameLang":"ja-Kana"},{"creatorName":"MURAKAMI, Noriyuki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-25"}],"displaytype":"detail","filename":"06harc-bull-no207p51-.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","license_note":"© 国立研究開発法人 農業・食品産業技術総合研究機構 \nNational Agriculture and Food Research Organization, Japan\n","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"06harc-bull-no207p51-.pdf","url":"https://repository.naro.go.jp/record/2372/files/06harc-bull-no207p51-.pdf"},"version_id":"b95063d5-cdd5-4438-b6a5-96a59d335843"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"水田輪作","subitem_subject_scheme":"Other"},{"subitem_subject":"レーザ均平機","subitem_subject_scheme":"Other"},{"subitem_subject":"衛星測位","subitem_subject_scheme":"Other"},{"subitem_subject":"無人航空機測量","subitem_subject_scheme":"Other"},{"subitem_subject":"lowland crop rotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laser leveler","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GNSS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerial survey by UAV","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"水稲乾田直播栽培における前年整地の導入効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水稲乾田直播栽培における前年整地の導入効果"},{"subitem_title":"Effectiveness of Prior Year Ground Leveling Systems for Direct Rice Sowing in Dry Paddy Cultivation","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["35","370"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"2372","relation_version_is_last":true,"title":["水稲乾田直播栽培における前年整地の導入効果"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T16:02:35.700189+00:00"}
