摘 要: 在设施农业中,通常所采用的人工光源是荧光灯与高压钠灯。近年来,随着光电技术的发展,发光二极管(LED)的亮度与效率也大幅度提高,使得这种光源在设施农业生产中的应用变为可行,尤其对封闭可调控的设施农业环境(如植物工厂,组织培养室、植物生长箱等)是一种非常合适的人工光源。为此,主要介绍了LED在设施农业中的应用及发展趋势。 Tubular fluorescent lamp (TFL) and high -pressure sodium lamp (HPS) are the principal artificial light sources used in agriculture. Parallel to the recent development of photo electronics, it becomes possible that super bright light- emitting diode (LED) is commercial and applied in installation agriculture. LED has more advantages than conventional light sources, such as high energy - conversion efficiency, using DC power, small volume, long ,life, wave length specific, light intensity/quality adjustable, low thermal energy output and so on. So it adapts to be used for plant growth in confined environment, which includes plant tissue culture room, growth chamber and so on, as a promising light source.
