The results are summarized as follows: 1. Effect of the competition on the growth of rice plant is little until the middle stage of growing season. But, it is large after the middle stage of growing season. The number of tiller is affected remakably by competition than plant height. 2. When barnyardgrass spaceing is thin in the botanical composition, an injurious effect on the hulled rice yield was reduced by increasing of nitrogen application. When it is thick, however, this tendency is reverse. 3. Planting time of barnyardgrass is greater for effect of competition on the rice plant than its standing number. 4. In the competition, the decreasing of LAI, dry weight of the top, and productive structure were found.[要約]水稲とタイヌビ工の人工群落において、窒素施用量の変化やヒエの発生時期および密度の変化が水稲の生理生態的条件や収正などにいかなる影響をおよぽすか観察した。1.　生育初期には競争による生育体ヘの影響は小さいが、生育の進行につれて大きくなって来る｡とくにその場合、茎数へのひずみが強く現われ、これが水稲収量に大きく関係してくる｡2. 競合が生ずる場合、競争に勝る植物が他の植物を相乗的に圧迫するので、雑草比が少ない場合は窒素施用量の増加が収量につながって行くが、雑草比が大の場合は窒素施用量を増加するほど減収は著しくなる。3. ヒエの水稲-与える影響として、発生時期の差が大きな割合を占め、発生する時期が遅そければ発生本数がある程度多くてもそれほど水稲に影響をおよぼさない｡4. 競合がはげしい状態下の水稲体は、LAI、生産構造などの同化部分の量的な減少が大きく現われるが、それだけが競合によるひずみとするのでなく、生態的条件に加味された質的なひずみを考慮しなければならない｡","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学農学部"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04538889","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Okumura, Toshikatsu"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部農学科作物学研究室"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Crop Science Laboratory, Department of Agriculture, Faculty of Agriculture, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"奥村,  俊勝"},{"creatorName":"オクムラ, トシカツ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AN00064044-19710315-0009.pdf","filesize":[{"value":"704.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00064044-19710315-0009.pdf","url":"https://kindai.repo.nii.ac.jp/record/5236/files/AN00064044-19710315-0009.pdf"},"version_id":"46aec1ac-5f05-4036-87f2-51f256773370"}]},"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_thumbnail":{"attribute_name":"サムネイル","attribute_value_mlt":[{"subitem_thumbnail":[{"thumbnail_label":"AN00064044-19710315-0009.jpeg","thumbnail_url":"/api/files/a62db037-9c60-49a3-879e-c0d140938c6c/AN00064044-19710315-0009.jpeg?versionId=3b9b84f0-d4eb-4eef-b94a-13ff6d8c45d6"}]}]},"item_title":"水稲とヒエの人工群落における生態学的研究(第1報) : 窒素施用量,およびヒエの発生時期と密度が水稲にあたえる影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水稲とヒエの人工群落における生態学的研究(第1報) : 窒素施用量,およびヒエの発生時期と密度が水稲にあたえる影響"},{"subitem_title":"Ecological studies on the plant community of rice plant and barnyardgrass (1) : Effect of planting time, spacing of barnyardgrass and amount of nitrogen application on rice plant","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["1469","3078"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-02"},"publish_date":"2008-04-02","publish_status":"0","recid":"5236","relation_version_is_last":true,"title":["水稲とヒエの人工群落における生態学的研究(第1報) : 窒素施用量,およびヒエの発生時期と密度が水稲にあたえる影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:36:41.360617+00:00"}
