碩士 === 國立中興大學 === 生物產業機電工程學系所 === 99 === This research uses wireless multimedia sensor networks (WMSNs) technology to develop the paddy filed server (PFS). PFS system provides real-time remote monitoring of rice growth and environmental change, including temperature, relative humidity, sunshine degree, soil moisture and plant images, which can be a long-term collection of paddy field environmental information and provide historical data search, when reference leaf color in rice cultivation as a fertilizer management. The experimental field areas as in Wufeng township, National Chung Hsing University experimental farm, were cultivated 4 of fertilizing capacity of rice, long-term monitoring of environmental change, and through image processing to identify the leaf color. Discussion after planting 58-91 days for leaf color associated with the chlorophyll content, The results showed that night taking pictures of leaves and chlorophyll content of the correlation coefficient of 0.86, while the daytime image in the illumination range of 50,000 to 60,000 lux when taken as the correlation coefficient was 0.87, when taken as the period for 8 am to 10 am related coefficient of 0.81. Images were obtained during the night to calculate the leaf color index formula, the determination coefficient of 0.94, can optimize fertilization, to avoid excessive nitrogen fertilizer or previous crop affecting the taste enough to result in lower production, to achieve consistent quality.
