臺灣冬季裡作栽培芻料用燕麥活化休耕地之經濟效益評估

本研究之目的在探討冬季裡作種植芻料用燕麥之經濟效益，藉以活化休耕地。試驗調查分別於2010年12月在苗栗縣後龍鎮，以及2015年11月於彰化縣福興鄉二地的水旱田，於二期水稻收穫後休耕期間，進行冬季裡作芻料用燕麥生產，調查燕麥生產性狀、成本及收益，以評估其經濟效益。結果顯示，福興鄉與後龍鎮燕麥之株高分別為123.8±6.1和73.0±3.3公分，鮮草產量每公頃分別為51.0±6.1和33.0±3.4公噸。福興鄉試區燕麥之生產、收穫成本與銷售收入，分別為每公頃32,300元、26,000元和67,500元，後龍鎮試區則分別為每公頃18,125元、10,500元和39,600元。後龍鎮試區淨收益每公頃為10,975元，福興鄉則為的9,200元。本研究顯示活化休耕地，冬季裡作栽培芻料用燕麥，具有潛力，有助於提高國產冬季牧草自給率，惟需考量氣候與栽培制度可能影響作物生產，同時受到隔年一期作水稻插秧適期之時間壓力，增加燕麥收穫調製的風險。

The purpose of this study was to investigate the economic benefits of planting forage oats to activate the fallow farmland in winter. The experimental period was from 2010 to 2016. The experiments were conducted at Hou-Long in Miao-Li County and at Fu-Xing in Chang-Hua County, respectively. During the fallow period after harvesting the second rice crop, the oats were planted for forage purpose in winter. The results showed that the plant heights of the oats were 123.8 ± 6.1 and 73.0 ± 3.3 cm at Fu-Xing and Hou-Long, respectively, and the yields of fresh oats were 51.0 ± 6.1 and 33.0 ± 3.4 mt/ha at Fu-Xing and Hou-Long, respectively. The input of costs for oats planting production and harvesting and the output of income for oats production at Fu-Xing were 32,300, 26,000 and 67,500 NT$/ha, respectively, while those at Hou-Long were 18,125, 10,500 and 39,600 NT$/ha, respectively. The net income was 10,975 NT$/ha at Hou-long, while that was 9,200 NT$/ha at Fu-Xing. This study showed that it was economically beneficial for activating fallow farmland for planting oats in winter. It might be helpful to improve domestic requirement of forage and increase self-sufficiency rate during spring period. Planting the oats as forage use in winter the climate factors might affect oat production. Also the oat production might cause time pressure for harvesting oats because of the 1st rice crop season coming soon in the fallow farmland.
