近年我國農業人口因都市化與少子化而持續下降，且農業勞動力高度高齡化，導致育苗等基礎農務面臨人力不足的挑戰。在此背景下，導入自動化技術以降低人力依賴並提升作業穩定性已成為農業發展的重要方向，因此本研究開發一套以潮汐灌溉（Ebb and Flow）為核心之自動化有機育苗系統，期望提供一致可控的育苗環境，並蒐集後續數位孿生模型所需之環境與生長資料。 本系統整合育苗箱、水位控制機構、感測器模組，以及用於記錄幼苗生長影像之影像紀錄設備，可自動進行進排水並回收水資源，同時量測光照、土壤濕度與環境溫濕度等參數，並擷取幼苗生長影像以支援數位孿生建立。實驗結果顯示，本系統能有效促進種子發芽並維持幼苗初期穩定生長，驗證潮汐灌溉應用於育苗之可行性，然而，育苗箱深度設計、設備清潔維護流程及幼苗生長一致性仍需改善，以提升整體系統性能與實務應用價值。;The agricultural workforce has been declining due to urbanization and low birth rates, while rapidly aging demographics have intensified labor shortages in fundamental tasks such as seedling production. Addressing this issue requires the adoption of automation technologies to reduce labor dependency and improve operational stability. Motivated by this need, this study develops an automated organic seedling cultivation system based on the Ebb and Flow irrigation method, aiming to provide consistent growth conditions and generate environmental and growth data for future digital-twin applications. The system integrates seedling boxes, a water-level control mechanism, sensor modules, and an image-recording unit for capturing seedling growth. It automates water inflow and drainage with water recycling, measures parameters such as light intensity, soil moisture, and water level, and records growth images. Experimental results indicate that the system effectively supports seed germination and stable early seedling development, demonstrating the feasibility of applying Ebb and Flow irrigation to seedling cultivation. Nevertheless, improvements in box-depth design, maintenance procedures, and seedling uniformity are needed to enhance system performance and practical applicability.
