摘要

伊娜谷香糯米為南投縣仁愛鄉松林部落原住民特有的水稻品種，其在文化傳承、種原維護及農業生態上都有特殊性及重要性，值得珍視與維護。行政院農業委員會臺中區農業改良場配合行政院核定「國土生態保育綠色網絡建置計畫」，投入南投縣仁愛鄉松林部落伊娜谷香糯米之友善環境資材導入及建立其生物多樣性資料。於友善環境資材導入部分，臺中農改場以溶磷菌配合矽資材導入香糯米的栽培，試驗結果顯示友善環境資材導入僅在千粒重與對照有差別，兩者在產量上無顯著差異，而不同友善環境資材間的交感作用及其與環境因子的作用都會對水稻生育帶來不同的影響，因此友善環境資材的投入須審慎評估當地的土壤與氣候環境特性，才能真正發揮其效用。生物多樣性資料建立部分，本次生態調查共調查到57種458隻次的個體，並發現鄰近森林環境的田區有較高的生物多樣性，而水田濕地提供蛙類良好的環境，本次調查所發現數量豐富的澤蛙族群可作為後續評估友善環境栽培的指標物種。綜觀目前友善環境資材導入及生態調查的成果，相關試驗仍應著眼於長期自然生態的維護與農業生產的平衡，臺中農改場亦將持續進行試驗及生態方面的資源投入，期能達到里山倡議維持人與自然和諧共生的願景。

Enaku aromatic glutinous rice is a special variety originated in Sonlin tribe, Ren'ai Township, Nantou County. It plays an important role not only in cultural tradition of Sonlin tribe, but also the agricultural ecosystems. To maintain the ecosystems and to make reasonable use of the nature resource, we tried to input ecofriendly-materials into the cultivation of Enaku aromatic glutinous rice, and conduct ecological investigation in order to understand the ecosystems. The trials of input phosphate-solubilizing bacteria and silicon-materials as ecofriendly-materials showed that there're no significant different between ecofriendly-materials treatment and control group on yield and yield-component traits except thousand-grain-weight. It also showed that the use of different materials simultaneously should be assessed carefully due to their effects are highly influenced by environmental factors and the correlations between them. The ecological investigation found 57 species with 458 bions. The field which is closer to the forest was found to have much more species and bions and the paddy field provided suitable environment for frogs (Fejervarya kawamurai) which can be biological indicator for future investigations. Finally, to meet the goal of the Satoyama Initiative, further trials and investigations should pay more attention on the long-term agricultural ecosystems to reach the balance between biodiversity and human well-being.
