The average values of the fluxes measured for the major rice at Khon Kaen and Surin were 19.8 and 13.3 mg m-2 h-1, respectively, and for the second rice 15.1 and 15.4 mg m-2 h-1, respectively. High CH4 emission for the major rice at Khon Kaen was due to the high content of fresh organic matter, deep water depth and soil itself which has a low oxidizing capacity and low clay content. Moreover, the comparatively low CH4 flux recorded during the 67-day period after flooding in the major rice at Surin was caused by the decomposition of the easily decomposable part of fresh organic matter before flooding.\nThe estimated seasonal emission rates of CH4 for the major rice at Khon Kaen and Surin were 61.3 and 39.3 g m-2, respectively, and for the second rice 34.8 and 44.4 g m-2, respectively. Total CH4 emission from Thai paddy fields was estimated to be 3.7 Tg year-1 when the total paddy area was taken into consideration.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"東北タイのKhon KaenおよびSurinの水田圃場において，雨季作および乾季作での水稲栽培期間中のメタンフラックス，土壌Eh，および地温の季節変動の測定を行った。雨季作栽培期間中のメタンフラックスの平均値は，Khon KaenおよびSurinで，それぞれ，19.8および13.3mg m-2 h-1であり，乾季作栽培期間中のそれらは，それぞれ，15.1および15.4mg m-2 h-1であった。雨季作における，両水田のフラックスの違いは，土壌の新鮮有機物含盤，田面水位，および酸化容量や粘土含量など土壌の理化学生の違いによると考察された。特に，Surinの雨季作における，湛水後67日間の低いフラックスは，湛水前に新鮮有機物の易分解性画分の多くが分解されたためと考えられた。\n季節変動の測定より見積もられた栽培期間全体のメタン発生盤は，雨季作において，Khon KaenおよびSurinで，それぞれ，61.3および39.3g m-2であり，乾季作では，それぞれ，34.8および44.4g m-2であった。本プロジェクトにおける一連の調査結果から，タイ全体の水田からのメタン発生量は3.7Tg year-1であると見積もられた。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available"}],"filename":"jircas_journal7-_87-96.pdf","filesize":[{"value":"474KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_journal7-_87-96","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000173/files/jircas_journal7-_87-96.pdf"},"version_id":"691e65d0-f002-4477-a197-3ff53241f8af"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000173","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13407686","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11030483","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"fresh organic matter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"global warming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"methane flux","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"paddy soil","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sandy loam soil","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Methane Emission from Paddy Fields in Northeast Thailand","subitem_title_language":"en"},{"subitem_title":"東北タイにおける水田からのメタン発生","subitem_title_language":"ja"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Methane Emission from Paddy Fields in Northeast Thailand","item_type_id":"40039","owner":"8","path":["1705364365060"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-22"},"publish_date":"2024-03-22","publish_status":"0","recid":"2000173","relation_version_is_last":true,"title":["Methane Emission from Paddy Fields in Northeast Thailand"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2024-03-22T05:49:57.968925+00:00"}
