The application of light-emitting diode(LED) in modern agriculture has been increasingly concerned by countries worldwide with the development of LED technology and the decrease of its cost. LED has many advantages compared with the other electric light sources. First, it has good traits of photoelectric such as small size, longer life, low energy consumption, high luminous efficiency and low heat production. Second, light spectral composition of LED light source can be easily integrated or tailored according to the need of plant. LED light sources can efficiently promote the growth&development, photo-morphogenesism, yield and quality of agricultural organisms. In this paper, application status of LED in agriculture was outlined, potential of LED application was analyzed, and key factors that limits application of LED in agriculture was pointed out. Finally, future development strategy, orientations and countermeasures of LED application in modern agriculture were discussed. |
