But we found that transplanted tropical fruit tree (papaya, guava, loquat) were eaten by grazing cattle. We would have to take any measures against such probrems. We had studied four measures to prevent tropical fruits tree from grazing cattle. Following measures on protecting tropical fruit tree from grazing Japanese black cattle were made : 1. Effects of odoriferous materials on protecting tropical fruit tree from grazing cattle ; 2. Effects of polyethylen-net bag method on protecting tropical fruit tree from frazing cattle ; 3. Effects of wire-net method on protecting tropical fruit tree from grazing cattle ; 4. Effects of wire-mesh cage method protecting tropical fruit tree from grazing cattle. In experiment of any odoriferous materials (butyric acid, ammonia, trimethylamine, propionic acid, butylmercaptan) the effect of them were not for long time because of volatilizing in a short time after setting. In second experiments many tropical fruit tree leaves covered with polyethylen-net bag were bitten by grazing cattle. In third experiment striken the steel poles in underground to stand wire-net were fallen by grazing cattle. However in fourth experiment wire-mesh cage method protected ropical fruit tree entirely from grazing cattle during long experimental periods. the most effective grazing protection in four experiments. We recognized that wire-mesh cage method was the most effective proection from grzing cattle","subitem_description_type":"Other"},{"subitem_description":"未公開：P.5以降（別刷論文のため）","subitem_description_type":"Other"},{"subitem_description":"研究報告書","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"平川守彦"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/13594"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"NCID","subitem_1522646572813":"BA35638033"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1998-03","bibliographicIssueDateType":"Issued"}}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"07660437.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2005074/files/07660437.pdf"},"version_id":"a9a6f1e5-d3f9-40a1-b0f3-d4b364657113"}]},"item_title":"亜熱帯果樹－放牧生産システムに関する研究","item_type_id":"15","owner":"1","path":["1642838403123","1642838407312"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-12-02"},"publish_date":"2009-12-02","publish_status":"0","recid":"2005074","relation_version_is_last":true,"title":["亜熱帯果樹－放牧生産システムに関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T02:28:53.704970+00:00"}
