摘要:	本研究係以一植物培育裝置為研究對象，此植物培育裝置主要是為結合水耕栽培與魚類養殖為一體之裝置。此裝置就像一個小型生態系統，包含有能量轉換及營養轉換。本研究主要的目的是為評估此植物培育裝置應用之可行性。本論文栽培以過濾海綿作為種植空心菜之介質，並設置循環水系統作為植物水分來源，以水耕栽培方式取代傳統的土耕栽培方式。期望植物可利用過濾後魚體排泄物的營養成份，達到養殖和栽培的複合式功能。同時，植物培育裝置電力來源來自於太陽能板，以供給沉水馬達與燈泡所需消耗之電能。植物培育裝置結果顯示，水中酸鹼值(pH)、導電度(Electrical conductivity, EC)此數值符合植物生長與魚體生活水質之標準。總凱氏氮(Total Kjeldahl Nitrogen, TKN)、總磷(Total phosphorus, TP)，因飼料供給太多，數值上有不如預期般結果。溶氧(dissolved oxygen, DO)除了陰雨天外均為正常狀態。植物成長高度結果顯示，植物層L1(裝置上層)與實驗植物層L2(裝置下層)之間無明顯差異，本研究結果之成果明顯高於對照組(自然生長植物)平均8cm。重量結果顯示裝置內20天後試驗平均重於對照組1g至1.5g，裝置內20天試驗魚體的增加重量平均為7.88 ±1.19。期間無因為環境及裝置的影響有死亡或者重量增加緩慢的狀況發生。其他地區及場所有許多廢水再利用的裝置，這些裝置大都採用大型耕作養殖的方法，與本專利裝置有許多的差別。此裝置未來可以放置公共場所間或一般家庭內使用，放於公共場所內使用，不僅美觀，並有可以有教學的作用，一些科技公司上已有類似裝置正推出販售於中小學學校。 The purpose of the study is to evaluate a plant cultivation device, which combines hydroponics and fish farming with utilization of solar energy for system power. The patented device is designed as a small unit and can be used in a relatively limited space for operation. It was not assessed for feasibility.This plant cultivation device used filter sponge as a medium in planting spinach accompanied with a water circulating system for irrigation. After filtration and plant root absorption, the wastewater from the fish tank containing nutrients, which is mainly fish feces, can be treated and recycled back to the aquarium. For aquaculture, fish purchased from common market was used as experimental subjects. For vegetables, the device can use any kind of leafy crops. During this experiment, another set without fish served as the control group was used for comparison.The results of this study shows that the waters pH and conductivity were in accordance with the requirement for plants growth and survival of the fish. But the total Kjeldahl nitrogen and the total phosphorous were higher than expected probably due to over-feeding. The dissolved oxygen (DO) was noticed to be related to the operation time of submersible motor. Besides, during several consecutive raining days, DO were less than what was observed in normal days. The air and raising water temperature differences observed was about 3℃ in average. Normally, the water temperature, disregard in summer or winter, was very closely related to the change of the vegetation covering the tank material.For the study of the plant growth, that there is no difference between plant at L1 (grow in the higher level) and L2 (lower level).The differences was up to 8 cm in average; however, in term of weight, the difference was only between 1g to 1.5 g. After the raising period of 3 weeks, the fish were attrition average 7.88 ±1.19 all in good condition with increases of the weight.The device used in this study is relatively compact and can be utilized in the public area or home without occupying lots of space and also can be fully functional for different purposes, such as educational, leisure, and aesthetic. Currently, there are similar devices sold to primary and secondary schools or other public areas.
