The contents of N, C, P, K, Mg, Ca and water could be measured with good agreement. Calibration equations satisfied enough accuracy by the sequential measurements of sugarcane leaves in the various growing stages. NIR measurement was carried out not only shredded sugarcane samples but extracting juice samples, and then the measurable components were clarified. 2)Close range measurement : The spectrum data of cane leaves were measured with the wavelength range from 350nm to 2500nm using a portable spectrometer. The degrees of water stress and nutrition were availably detected by the spectrum data. 3)Short distance measurement : The feasibility study was carried out to check whether the small size unmanned helicopter was useful or not for the sensing of growing conditions from short distance. Some images of sugarcane field were taken and processed in Minami-Daito Island. The growing conditions were observed well. 4)Intermediate distance measurement : The image processing methods by a hyper spectrum camera were investigated to detect the nutrition condition of sugarcane field. 5)Long distance measurement : High-resolution satellite images by QuickBird and IKONOS were applied to field map drawing, NDVI analysis and others in Minami-Daito and Kita-Daito Islands. The mapping was carried using the results. 6)Complementary measurement : Three sets of robotic weather station were placed in Kita-Daito Island, and weather data were collected. Evapo-transpiration was estimated and compared with the remote sensing data. Finally, the relations of the measurement distance and measurable components and accuracy were discussed.","subitem_description_type":"Other"},{"subitem_description":"未公開：P.50～P.94、P.145～P.152（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":"上野正実"}]},"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/20.500.12000/12348"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"NCID","subitem_1522646572813":"BA79373548"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2006-03","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":"16380176-8.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-8.pdf"},"version_id":"965e43d6-a862-4ee6-a10b-57d2ed837fe1"},{"accessrole":"open_access","filename":"16380176-7.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-7.pdf"},"version_id":"f1668b9e-05a3-4061-889a-4a8d9d3dcc0d"},{"accessrole":"open_access","filename":"16380176-6.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-6.pdf"},"version_id":"451ed9c2-a314-4f30-b28d-90d450871475"},{"accessrole":"open_access","filename":"16380176-5.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-5.pdf"},"version_id":"46031214-2c09-48af-870a-7f086ece668e"},{"accessrole":"open_access","filename":"16380176-4.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-4.pdf"},"version_id":"49394149-aaa5-458f-a06f-4c4e25ed1cc5"},{"accessrole":"open_access","filename":"16380176-3.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-3.pdf"},"version_id":"26c6d958-d0b4-40d4-91eb-da37ce1aba31"},{"accessrole":"open_access","filename":"16380176-2.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-2.pdf"},"version_id":"17023d5a-ec79-4b6c-aa9e-3a0192ce8bb5"},{"accessrole":"open_access","filename":"16380176-1.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2004863/files/16380176-1.pdf"},"version_id":"aef47c8a-00d3-4134-9a58-471c8bebcd41"}]},"item_title":"サトウキビの栄養状態の階層的光センシングとその利用技術の開発","item_type_id":"15","owner":"1","path":["1642838403123","1642838407312"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-09-04"},"publish_date":"2009-09-04","publish_status":"0","recid":"2004863","relation_version_is_last":true,"title":["サトウキビの栄養状態の階層的光センシングとその利用技術の開発"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T02:24:33.662176+00:00"}
