The candidate for investigation area is Shuangcheng Shi, Shunli Cun Region of China. In this project, survey and analysis of farmland soil was continued for productivity improvement of farmland, and the effective use of livestock excrement. The annual precipitation of the investigation area is 500 mm (semiarid region), most rain will fall between June and August. In the village, about 1,300 dairy cows and 1,800 pigs are bred. However, there is little application to farmland of stock raising excrement, such as compost, and most of cow dung is deposited on the road side. The paddy field zone of the village central part is fine granule gley soil, and its drainage is poor. Soil average pH (H_2O) was 8.2 (alkalinity). Moreover, soil exchegable Ca and Mg were excess as 10 times of the standard of Japan. On the other hand, there were few available phosphoric acid and K contents, and mineral balance was bad. The upland field soil of comparatively high hills had elution of minerals. Although soil pH was low and Ca and Mg content were decrease rather than paddy soil, however compared with the standard of Japan, it was a still high level. Growth of the corn which is a mainly cultivated crop in the upland fields and there were no correlation with the soil pH or EC. The physical property (hardness) of soil influenced growth of corn. Soil hardness became low when the rate of the soil macro aggregate increased. The soil macro aggregate increased by the application of the compost, and the soil physical property improved. As a conclusion, compost application to farmland especially to upland field improves crop productivity by soil physical property improvement.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162766","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takahashi, Yoshihiko"}]},{"nameIdentifiers":[{"nameIdentifier":"162767","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Han, Dong-Sheng"}]},{"nameIdentifiers":[{"nameIdentifier":"162768","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Oyanagi, Wataru"}]},{"nameIdentifiers":[{"nameIdentifier":"162769","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hori, Hidetaka"}]},{"nameIdentifiers":[{"nameIdentifier":"162770","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Zhang, Yong-Qiang"}]},{"nameIdentifiers":[{"nameIdentifier":"162771","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Zhang, Yan-Ju"}]},{"nameIdentifiers":[{"nameIdentifier":"162772","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Qin, Zhi-Wei"}]},{"nameIdentifiers":[{"nameIdentifier":"162773","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasuga, Ken-ichi"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 能彦"}],"nameIdentifiers":[{"nameIdentifier":"162758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"韓, 東生"}],"nameIdentifiers":[{"nameIdentifier":"162759","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小柳, 渉"}],"nameIdentifiers":[{"nameIdentifier":"162760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"堀, 秀隆"}],"nameIdentifiers":[{"nameIdentifier":"162761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張, 永強"}],"nameIdentifiers":[{"nameIdentifier":"162762","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張, 艶菊"}],"nameIdentifiers":[{"nameIdentifier":"162763","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"秦, 智偉"}],"nameIdentifiers":[{"nameIdentifier":"162764","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"春日, 健一"}],"nameIdentifiers":[{"nameIdentifier":"162765","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":"2019-08-20"}],"displaytype":"detail","filename":"65(1)_39-48.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65(1)_39-48.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28316/files/65(1)_39-48.pdf"},"version_id":"96519344-ae45-47d3-825e-acf48920932c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"中国","subitem_subject_scheme":"Other"},{"subitem_subject":"半乾燥地","subitem_subject_scheme":"Other"},{"subitem_subject":"堆肥","subitem_subject_scheme":"Other"},{"subitem_subject":"アルカリ土壌","subitem_subject_scheme":"Other"},{"subitem_subject":"China","subitem_subject_scheme":"Other"},{"subitem_subject":"semiarid area","subitem_subject_scheme":"Other"},{"subitem_subject":"compost","subitem_subject_scheme":"Other"},{"subitem_subject":"alkali soil","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":"中国黒竜江省双城市順利村一帯における農地土壌の特性と作物生育","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中国黒竜江省双城市順利村一帯における農地土壌の特性と作物生育"},{"subitem_title":"中国黒竜江省双城市順利村一帯における農地土壌の特性と作物生育","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1592"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-29"},"publish_date":"2013-05-29","publish_status":"0","recid":"28316","relation_version_is_last":true,"title":["中国黒竜江省双城市順利村一帯における農地土壌の特性と作物生育"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:17.907816+00:00"}
