No full text台灣位處於亞熱帶，夏季經常有颱風侵襲，冬季則有東北季風影響，近年來由於全球暖化與氣候變遷，致使強風與豪雨對作物栽培的威脅愈來越嚴重，故國內應用溫室進行農業生產將為未來趨勢。本研究調查並彙整國內溫室常用種類、型式，並以國內大量使用的溫室中，選擇具發展潛力的溫室型態，進行溫室標準圖面更新與數值模擬方法之建立。整合跨領域研究團隊的過程中，目前已完成簡易溫室之標準圖樣草案，並繪製簡易溫室之詳細圖，提供農民選用準則，為爾後本土溫室產業發展及主管機關訂定標準圖樣之參考。另外運用計算流體力學與結構力學之流固耦合模擬方法，建構溫室外部風場與結構強度的模擬分析流程，並以縮尺模型的風洞試驗來驗證數值模擬結果是否合理，也藉由數值化模擬分析技術的建立，進而對溫室結構接合元件、內部桁架與外部結構強化進行研究改良，初擬簡易溫室設計規範與資材標準化等資訊，協助提升簡易溫室的設計能力與製造技術
溫室生產能源利用效率評估及餘能再利用技術之建立
No full text本研究建立一套溫室設施排風餘能利用微風力發電雛型系統，利用設施之大型通風扇所產生之穩定風源下，設計一導風與整流機構，架設於通風扇出風口，使風能有效收集集中導向微風力發電機，再透過最大功率追蹤器 (Max Power Point Tracking) 進行最大功率之輸出且及時偵測風機電壓、充電電流及電池電壓並進行負載管理，並搭配以PLC 為核心的控制系統，利用雙電瓶獨立進行充、放電動作，控制程式依據電瓶電壓判斷並自動切換充、放電模式。將風力發電機所產生之電力儲存於電瓶中，再由電瓶所儲存的能量提供給負載使用，形成一套儲能與負載最佳化自動控制系統，達到餘能回收再利用之效果，且實踐節能減碳之目的。另完成溫室自動化硬體輸出入設施之盤點與規劃，並以可程式控制器為系統核心，依作物栽培專業及能耗考量區分日夜間不同軟體控制策略，再輔以人機介面主機做為重要控制參數之設定介面，以做為實務作物栽培之最適化控制。另一方面，溫濕度數據已採自動化方式進入資訊系統資料庫，並可採即時掃瞄或歷史查詢方式遠端調閱資料。設施能源調查是對生產現場的能源利用資訊做蒐集，利用已開發之電能功率檢測模組，檢測生產設備的實際耗能狀況，並收集生產資材與生產成效的相關資訊，將其整理分析後，建立一能源利用效率的評估模式，提供設施栽培生產能源效益最佳化之策略，進而提升能源利用效率
Waxy allele diversification in foxtail millet (Setaria italica) landraces of Taiwan
No full textFoxtail millet (Setaria italica (L.) P. Beauv.), the second most cultivated millet species, is well adapted to diverse environments and remains an important cereal food and forage crop in arid and semiarid regions worldwide. A symbolic crop for indigenous Austronesian peoples, foxtail millet has been cultivated in Taiwan for more than 5,000 years, and landraces reflect diversifying selection for various food applications. A total of 124 accessions collected within Taiwan were assessed for Wx genotypes. Four identified Wx alleles, I, III, IV, and IX were caused by insertion of various transposable elements (TEs) and resulted in endosperm with non-waxy, low amylose content (AC), and waxy, respectively. A total of 16.9%, 4.0%, 49.2%, and 29.8% of accessions were classified as type I, III, IV, and IX, respectively; approximately half of the accessions belonged to the waxy type, indicating that glutinous grains were favored for making traditional food and wine. The TE insertion affected splicing efficiency rather than accuracy, leading to significantly reduced expression of wx in types III, IV, and IX, although their transcripts were the same as wild-type, type I. Consequently, the granule-bound starch synthase I (GBSSI) contents of the three mutated genotypes were relatively low, leading to waxy or low AC endosperm, and the Wx genotypes could explain 78% of variance in AC. The geographic distribution of Wx genotypes are associated with culinary preferences and migration routes of Taiwanese indigenous peoples-in particular, the genotype of landraces collected from Orchid Island was distinct from those from Taiwan Island. This information on the major gene regulating starch biosynthesis in foxtail millet endosperm can be applied to breeding programs for grain quality, and contributes to knowledge of Austronesian cultures
