碩士 / 國立屏東科技大學 / 環境工程與科學系所 / 105 / With the vigorous development of Taiwan's economy, the improvement of people's living standards, the rise of environmental protection and consumer awareness, and then change the type of agricultural production. The aquaponic is symbiotic aquaculture and aquaculture cultivation, the use of fish with the fish feces by nitrification reaction, the supply of plants to absorb nutrients, aquaculture fishery wastewater without changing the water, vegetables do not have a lot of fertilization, for the environment is very friendly, with the future sustainable development trend.
The aim of this study was to investigate the effects of the flow rate of the aquaponic system on the plants, and to cultivate the plants under the different planting patterns and to observe the best growth of the growth values, one for the outdoor overflow medium cultivation beds and deep water cultivation beds, and the other for the indoor Siphon medium culture bed and light-emitting diode artificial light source.
Outdoor aquaponic in ammonia and nitrite nitrogen in water were significantly improved, before planting, the average ammonia nitrogen was 0.12mg/L, the nitrite nitrogen was 8mg/L, experiment 1 of ammonia nitrogen average 0.01mg/L, nitrite nitrogen average 4mg/L; experiment 2 of ammonia nitrogen average 0.01mg/L, nitrite nitrogen average 3mg/L; experiment 3 of ammonia nitrogen average 0.01mg/L, nitrite nitrogen average 3mg/L; experiment 4 of ammonia nitrogen average 0.09mg/L, nitrite nitrogen average 2mg/L. While the main plant nitrate nitrogen nutrition to enhance the role, nitrate nitrogen before planting experiment of average 1.8mg/L, experiment 1 of nitrate nitrogen average 2.5mg/L; experiment 2 of nitrate nitrogen average 2.8mg/L; experiment 3 of nitrate nitrogen average 3.0mg/L; experiment 4 of nitrate nitrogen average 3.0mg/L.
From the results of experiment 1 to experiment 4, the best effect of this plant yield was the deep-water cultivation of overflow, the total weight of the plant under the deep-water cultivation of overflow and the Akadama soil was higher than that of the medium cultivation and the general soil tillage, especially when the cultivated inlet was 2,000 mL / min yield the most.
