摘要
光照是影响植物生长最重要的因素之一,近年来随着补光技术越来越广泛地应用于设施园艺与苗木生产中,国内外关于光照对植物生长的影响及人工补光技术的研究越来越多。首先综述了光照对植物的多方面影响,包括不同光照强度、不同光质(如红蓝光、白光、红外光和紫外光及其组合)、光周期等对植物光合作用及形态建成的影响,以及不同类型的农林植物对光照的反应差异。其次,总结了补光调节技术与策略研究进展,即根据光环境对植物生长的影响规律,设计光强、光质调节与补光效率调节技术。最后,就补光技术发展的方向与重点进行了展望,认为应将光源选型、光照在植物内部作用机理和多环境因素对植物的协同作用等方面作为今后提高补光效率的研究重点。
Light is the most significant factor in the regulation of plant growth.With the widespread use of lighting technique in plant flow line production and nursery stock production,the effects of plant lighting and the use of artificial lighting technique for promoting plant growth have been studied constantly and gradually.Accordingly,the present article reviews the effects of light(e.g.,intensity,quality and photoperiod)on plants.Light intensity,for example,affects the photosynthetic and growth rates of plants,whereas light quality affects seed germination,morphogenesis,and photosynthesis,and photoperiod affects morphogenesis and photosynthesis.The article also reviews recent progress in artificial lighting methods and strategies,such as the reduction of light waste and the development of dynamic lighting that promotes plant growth,and current trends in the development of lighting technique.That is to take light source,mechanism of light,and multi-factor influence to plant as research focus.
