This paper consists of the following outline of the nursery practices of Picea jezoensis: 1) Seed collection and storage, 2) preparation of the seed bed, 3) sowing, 4) the nursery management of 1-yr seedlings, 5) the nursery management of 2-yr seedlings, 6) transplantation, 7) the nursery management of 4-yr seedlings, 8) the nursery management of 5-yr to 6-yr seedlings, 9) preparation for plantation, 10) making the bark compost. To successfully propagate Picea jezoensis from seedlings, the author tried to prevent snow blight disease in the seed bed. The author found that this disease was caused by soil impaction and pressure on the seedlings by the weight of the snow, and proved that scattering volcanic conglomerates on the seed bed and snow fence surrounding the seed bed by timber to protect the seedlings against snow pressure effectively prevented this disease. This paper will form a standard for nursery practices of Picea jezoensis, and the propagation of this species from seedlings in Hokkaido.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54220","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OGASAWARA, Shigeo"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"元東京大学大学院農学生命科学研究科附属演習林　北海道演習林"},{"subitem_text_value":"University Forest in Hokkaido, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小笠原, 繁男"}],"nameIdentifiers":[{"nameIdentifier":"54219","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh106003.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh106003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25349/files/esrh106003.pdf"},"version_id":"bc37eb3e-9733-4f3c-844d-5cc6ca73701f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エゾマツ","subitem_subject_scheme":"Other"},{"subitem_subject":"火山礫","subitem_subject_scheme":"Other"},{"subitem_subject":"実生育苗","subitem_subject_scheme":"Other"},{"subitem_subject":"雪囲い","subitem_subject_scheme":"Other"},{"subitem_subject":"雪腐れ病","subitem_subject_scheme":"Other"},{"subitem_subject":"Picea jezoensis","subitem_subject_scheme":"Other"},{"subitem_subject":"seedling","subitem_subject_scheme":"Other"},{"subitem_subject":"snow blight disease","subitem_subject_scheme":"Other"},{"subitem_subject":"snow fence","subitem_subject_scheme":"Other"},{"subitem_subject":"volcanic conglomerate","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":"東京大学北海道演習林におけるエゾマツ実生育苗の実際","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東京大学北海道演習林におけるエゾマツ実生育苗の実際"}]},"item_type_id":"4","owner":"1","path":["2530","2529"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25349","relation_version_is_last":true,"title":["東京大学北海道演習林におけるエゾマツ実生育苗の実際"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.318062+00:00"}
