The farmers in Ay village roughly classify their soil into 6 categories which are determined by its color and stickiness as a index of soil fertility. Din deang tom and Din dam which are recognized as good soils by farmers have relatively higher amount of available phosphorous. Improved variety of rice, introduced by China in 2004, changed the rice cultivation acreage of indigenous rice varieties dramatically. However, the result of principal component analysis suggests that not only the farmers plant different varieties in order to match different soil conditions, but also they have an ability to be fit into a new technology.\n","subitem_description_type":"Abstract"}]},"item_10009_end_page_10":{"attribute_name":"終了ページ","attribute_value_mlt":[{"subitem_end_page":"114"}]},"item_10009_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"総合地球環境学研究所　研究プロジェクト4-2"}]},"item_10009_record_name_7":{"attribute_name":"図書名","attribute_value_mlt":[{"subitem_record_name":"2005年度　生態史プロジェクト報告書"}]},"item_10009_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"生態史プロジェクト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chikyu.ac.jp/ecohistory/top_jp.htm","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"総合地球環境学研究所"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chikyu.ac.jp/","subitem_relation_type_select":"URI"}}]},"item_10009_start_page_9":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"108"}]},"item_10009_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":"小手川, 隆志"},{"creatorName":"コテガワ, タカシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"458","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"櫻井, 克年"},{"creatorName":"サクライ, カツトシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotegawa, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"459","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAKURAI, Kastutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"352","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-29"}],"displaytype":"detail","filename":"report200513.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ラオス北部山地域における水田土壌の土壌情報学的解析","url":"https://chikyu.repo.nii.ac.jp/record/547/files/report200513.pdf"},"version_id":"f0ab5827-a1be-42d1-badc-5f18b025d74f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"北部ラオス｜水田｜土地利用","subitem_subject_scheme":"Other"},{"subitem_subject":"Northern Laos｜Paddy field｜Land Use","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":"book","resourceuri":"http://purl.org/coar/resource_type/c_2f33"}]},"item_title":"ラオス北部山地域における水田土壌の土壌情報学的解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ラオス北部山地域における水田土壌の土壌情報学的解析"},{"subitem_title":"Evaluation of paddy field on mountainous area in northern laos based on soil property and indigenous soil classification","subitem_title_language":"en"}]},"item_type_id":"10009","owner":"14","path":["153"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-09-29"},"publish_date":"2016-09-29","publish_status":"0","recid":"547","relation_version_is_last":true,"title":["ラオス北部山地域における水田土壌の土壌情報学的解析"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-06-20T16:46:43.270166+00:00"}
