中文摘要 | 果樹栽培中,有機肥料一直用來改善柑橘果實品質。尤其,最近永續農業陸續展開,有機施肥為有機生產過程之一要項。本文之目的為測定柑橘有機施肥之貢獻度及評估經濟效益與財務效果。選擇主產區桶柑、椪柑、柳橙與文旦四種主要柑橘果農為對象。使用路徑分析與柯布-道格拉斯生產函數進行測定。結果顯示有機施肥的效果貢獻度為2至7%,皆比化學肥料之貢獻度4至20%為低。其中,椪柑與文旦有機施肥經濟與財務效果較佳,但桶柑與柳橙則較差。此外,化學肥料比有機肥料效果高。因此,有機肥料須適量施肥,才更能使柑橘果樹的經營經濟有效。 |
英文摘要 | In fruit cultivation, organic fertilizers have been applied for improving citrus fruit qualities. Particularly, the sustainable agriculture has been spread out recently, the application of organic fertilizers is one of organic production process. This paper attempts to estimate the economical efficiency as well as the financial effects or organic fertilizer inputs for citrus. The citrus varieties, including Tankan tangor, Ponkan mandarin, Liucheng sweet orange and Wentan Pummelo, were selected for estimation. Path analysis and Cobb-Douglas production function were used. Results showed the effects of organic fertilizers application for citrus tress were between 2 to 7%, which were less than the rates 4 to 20% of chemical fertilizers. Besides, Ponkan, and Wentan Pummelo showed economic efficient in organic fertilizers application, but Tankan and Liucheng appeared ineffective. In addition, chemical fertilizers suggested more effective than that of the organic ones. Applying organic fertilizers just the right amount may provide efficiency and effects for citrus production. |
