研究目的
To investigate the best practice on using LED light for optimum growth of Brassica Chinensis and reduce turn around time at different kind of photoperiod study utilizing Wireless Sensor Network (WSN) technology as remote monitoring system.
研究成果
The continuous light (CL) photoperiod significantly improved the growth performance of Brassica Chinensis, suggesting its potential to enhance efficiency in plant factories or indoor farming systems. The developed intelligent system for LED control and environmental monitoring proved stable and effective.
研究不足
The study was conducted in controlled environments, which may not fully replicate natural growing conditions. The focus was on Brassica Chinensis, limiting the generalizability to other plant species.
1：Experimental Design and Method Selection:
The study employed an artificial light, hydroponic culture system to accurately control the growing environment, utilizing red and blue light LEDs as the light sources. Two experiments were conducted: pulse treatment (1 hour light and 1 hour dark) and continuous light (CL) photoperiod treatment.
2：Sample Selection and Data Sources:
Seeds of Brassica Chinensis were germinated and hydroponically grown in controlled environments. Observations included leaves count, height, dry weight, and chlorophyll content.
3：List of Experimental Equipment and Materials:
LED systems with specific red/blue ratios, Wireless Sensor Network (WSN) technology, microcontrollers, sensors for temperature, humidity, CO2, and Photosynthetically Active Radiation (PAR).
4：Experimental Procedures and Operational Workflow:
Plants were grown under controlled conditions with specific light treatments, and their growth parameters were monitored and recorded.
5：Data Analysis Methods:
Statistical analyses were performed using SPSS, with significance evaluated by ANOVA followed by the LSD approach.
