| Summary: | 碩士 === 景文科技大學 === 電腦與通訊系碩士班 === 106 === In recent years, plant factories have become more and more mature. Many large technology factories have invested in that. Oxygen motors are one of the power consumption equipment which accounts for 27% of electric energy. This research is an indoor hydroponic system as a family plant factory. The structure is the tidal phenomenon of the siphon water supply system and the impact of running water transport process. Then, you don’t need to use oxygen motor but the oxygen content in the water can reach the growth of the plant. This research analyzed the effect of the oxygen content in the growth of plants by hydroponic, using the ratio of exposure to air in four different plant roots for growth analysis. In conclusion, the growing plant roots, the plant are in contact with air for 5 centimeters, is the best distance and the oxygen generated by the impact of the siphon water supply system and the running water transport process can reach the oxygen content required for plant growth, thereby replacing the oxygen motor.
