A Red soil, which was derived from slate and was acidic in reaction(pH4.7) was mixed with coral sand at the soil to coral sand ratios of 10:0, 9:1, 8:2, 6:4 and 2:8. The mixtures were replicated twice. The cucumber was planted in pots (12 cm in dia. and 12 cm in height) which contained about 500 cc of the respective mixtures, and grown were 2 plants per pot for 3 weeks. The pH values were 4.7, 5.6, 6.1, 6.4 and 7.1 for the 10:0, 9:1, 8:2, 6:4 and 2:8 mixtures, respectively. The growth of the cucumber seedlings as determined by number of leaf, length of stem, and fresh and dry weights, was best obtained on the 9:1 mixtures followed by the 8:2. The seedlings showed symptoms likely to be calcium deficiency on the 10:0 mixtures of check and probable symptoms of manganese deficiency on the 2:8 mixtures. From the above it was concluded that the tested cucumber cultivar was not very tolerant to low soil pH, the coral sand was effective enough to ameliorate low pH of the soil, and incorporation of about 10% coral sand with the tested acid soil would make good nursery bed for the cucumber.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"沖縄農業研究会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Okinawa Agriculture Research Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1344-1477"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00083297"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"沖縄農業"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1986-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1・2","bibliographicPageEnd":"6","bibliographicPageStart":"1","bibliographicVolumeNumber":"21"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"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":"363.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015376/files/363.pdf"},"version_id":"84f08048-ef7f-4b77-8060-269abcf13c6d"}]},"item_title":"酸性土壌におけるサンゴ砂混合がキウリ苗の生育に及ぼす影響","item_type_id":"15","owner":"1","path":["1642838322143","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015376","relation_version_is_last":true,"title":["酸性土壌におけるサンゴ砂混合がキウリ苗の生育に及ぼす影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:36:03.985506+00:00"}
