傾斜地ウンシュウミカン成木園での樹別隔年交互結実栽培の収量性と作業効率 Yields and labor efficiency in a grove of mature satsuma mandarin trees cultivated with the intentional alternate bearing system in slopes TAKISHITA, Fumitaka 瀧下, 文孝 タキシタ, フミタカ 内田, 誠 ウチダ, マコト UCHIDA, Makoto 平岡, 潔志 ヒラオカ, キヨシ HIRAOKA, Kiyoshi 果実階級 剪定 摘果 収穫 採収能率 The yields, labor, and efficiency of harvesting, pruning, and fruit thinning were investigated in mature satsuma mandarin trees cv. 'Sugiyama unshiu' cultivated with the intentional alternate bearing system (IABS) on a granite soil slope with an incline of 30 degrees. The yield per tree was 121kg with the conventional thinning method (CTM) and 167kg with the IABS. The yield per field area (10a) was 5.08t with the CTM and 3.51t with the IABS. The percentage of SM fruit increased, and the labor efficiency of pruning was improved with the IABS. Regarding the value per field area, the thinning time was shorter and, because of the low level of yield, the harvesting time was shorter with the IABS than with the CTM. Total labor, including harvesting, pruning, and thinning per field area (10a), amounted to 97.3hrs for the IABS, 23.2hrs shorter than that for the CTM (120.5hrs). The total labor per yield (1ton) was 27.7hrs for the IABS, 4.1hrs longer than that for the CTM (23.6hrs). This lengthening was attributed to the low level of efficiency for harvesting caused by the small fruit. 独立行政法人 農業・食品産業技術総合研究機構 近畿中国四国農業研究センター 2010-05-01 jpn departmental bulletin paper VoR https://doi.org/10.24514/00001689 https://repository.naro.go.jp/records/1734 10.24514/00001689 10.24514/00001689 1347-1244 近畿中国四国農業研究センター研究報告 BULLETIN of THE NATIONAL AGRICULTURAL RESEARCH CENTER for WESTERN REGION 9 27 35 https://repository.naro.go.jp/record/1734/files/nwarc_report_No9p27-35p.pdf application/pdf 918.6 kB 2019-03-18
