摘　　要：植物工厂是设施园艺发展的必然趋势和高级阶段,其本质优势在于包括人工光照明在内所有生产要素可实现智能控制。LED光源是植物工厂应用的优选光源,可提供植物生理有效辐射范围内所有波长的光质,丰富了光生物学内涵,LED光源研发与应用催生了光生物学的分支即光质生物学学科。LED植物工厂是植物光质生物学研究与应用的理想场所和设施类型,植物光质生物学研究及LED光环境调控具有提高植物工厂植物产品产量与品质的重大应用价值,LED植物工厂产业的可持续发展有待于植物光质生物学的深入揭示。总结了LED植物工厂光质生物学的定义、内涵,并着重阐明了红蓝光替代全光谱的充要性、红蓝光质比优化、红蓝光连续光照、UV-LED光质生物学和昼夜节律等重点方向国内外研究与应用新动态,指出了未来LED植物工厂植物光质生物学研发与应用重点。Plant factory is an inevitable developmental trend and the advanced stage of protected horticulture worldwide. Its essential advantage lies in all production factors,including artificial lighting can be intelligently controlled. As an ideal light source for plant factory,LED can provide all wavelengths of physiologically active radiation,thus enriching the connotation of photo-biology. Research and application of LED hasten the ramification of photo-biology. Plant factory is an ideal place and facility type for studies and application of plant photo-biology.Studies on plant photo-biology,regulation and control of LED light environment are of important application value for improving yield and quality of plant products produced by plant factory. The sustainable development of LED plant factory industry awaits for further revelation of photo-biology. This paper summarized the definition,connotation of plant photo-biology of plant factory with LED light; highlighted the substitution sufficiency and necessity for full spectrum by red plus blue light,ratio optimization of red light to blue light,continuous light by red blue light,UVLED biology and circadian rhythms,etc. key research direction and new situation for research and application at home and abroad. Before ending,the paper pointed out the emphasis of R＆D and application of plant photo-biology for future LED plant factory.
