紫外（UV）光在植物光形态建成、次生代谢和叶色形成方面具有重要光生物学和光化学作用，在调控设施园艺优质高产方面具有潜在应用价值。综述了人工光植物工厂和太阳光植物工厂中UV 光的分布规律，特征波长UV 光的植物效应及其人工调控的必要性和调控策略。提出了植物工厂中UV-LED 利用的前景、目标和方法。
Ultraviolet light (UV), as an important part of continuous sunlight, refers to the wavelength ranging from 100 nm to 380 nm. Ultraviolet light functions crucially in photomophological formation, leafy coloration and secondary metabolism of plants via photobiology and photochemistry mechanisms, and has potential application value in high-quality vegetable production. Protected horticulture is a kind of modern production pattern for vegetables and mushroom, even fruits in greenhouse, plastic-covered tunnel and plant factory. In this paper, the distribution characteristics of UV light in plant factories with artificial light and sunlight, plant effects of UV-A, UV-B and UV-C and the necessity of artificial regulation are summarized. Moreover, the utilization prospects, targets and methods of UV-LED in plant factory are highlighted.
