利用LED植物工廠可控制照明與生長環境溫度等特性，本研究使用水耕的方式，針對網紋洋香瓜在LED植物工廠中，進行生產建構之研究。著重在研究不同光合有效輻射強度、不同光波長和不同光照時數與光照週期，對網紋洋香瓜之影響。記錄果實人工授粉的時間和採收時間以及後熟處理之品嘗味道鑑定。選用的洋香瓜品種為「香華」，因其收穫期早且產量較高之特性更符合經濟效益。研究結果顯示，光合有效輻射強度之強弱，對網紋洋香瓜的生長影響甚大，不同光波長之影響則較不明顯。在植株不同的生長階段，調整光照時數與光照週期，自幼苗期每日6小時光照，持續6週後調整為每日8小時光照持續3週，之後再調整為每日12小時的光照時數，是較具經濟效益的設定。果實的重量會受到單一植株上，著果成功並順利發育之果實數量，以及著果位置所影響。果實發育的成功率，平均為每人工授粉4顆即有成功1顆。一般而言，最佳賞味期約在後熟處理1天至3天時。

Light-emitting diode (LED) plant factory is using artificial controls, such as light, temperature and humidity to culture crops in labs. This research used muskmelon seedlings to establish a hydroponic method for muskmelon production under LED plant factory and focused on the photosynthetically active radiation (PAR) strength, light wavelength and different light periods to effect on muskmelon developments. The pollination time and harvest time were recorded and the fruit quality of varied harvest time and ripening days were compared. Muskmelon cultivar ‘Xiang-Hua’ (Cucumis melo L.) was chosen as the plant material for its earlier harvestable time and higher fruit production. The results showed that PAR strength was critical on muskmelon growth, whereas light wavelength was only minor effects. Considering the benefits for economic, hours for illumination and light periods should be adjusted during different plant growth stages. At the start for younger seedlings, light source should be provided for the hours per day for the first six weeks, then adjusted to eight hours per day for another three weeks, and finally to twelve hours per day. The weight of fruit is effected by the quantity of artificial pollination per plant and the location of the fruit setting. The fruit successfully developed at an average of one per four artificial pollination. Generally, the best fruit flavor was obtained at 1-3 days post ripening.
