摘　　要：连续光照是人工光下特有的无暗期、无中断且光照属性随时空可调控的光照模式,打破了传统明暗交替的光周期环境,延长光照时长,消除了暗期及暗期呼吸消耗,可通过改变属性特征动态来调控植物生长发育和产量品质的形成过程,达到优质高产高效的目标。LED光源在设施园艺中的广泛应用极大地增加了连续光照的内涵和应用价值。在人工光植物工厂条件下,连续光照具有较高的生产应用价值,亟待研究明晰植物连续光照生理响应生理机制及其调控途径,构建连续光照应用模式与智能控制系统。本文系统总结了连续光照的概念及内涵,短期和长期连续光照的生理影响,归纳了连续光照调控影响因素,提出了设施植物人工光生产中应用LED连续光照的策略。Continuous light(CL)is a kind of specific light mode for artificial light without dark period and interrupt,also its time-course dynamic traits are regulable.Therefore,CL can replace the traditional light mode with certain photoperiod by prolonging light duration,deleting dark period and respiration consumption,and designing the dynamic traits to regulate physiological processes of plant growth&development,yield and nutritional quality for high yield and quality.With the wide use of LED in protected horticulture,application value and patterns of CL have greatly increased in plant factory with artificial light.Nowadays,physiological responses and regulation mechanisms of plants to CL in plant factory with artificial light should be carefully investigated,then practical CL mode and control system should be developed.In this paper,CL definition and connotation is collected,and research advances worldwide of short-term and long-term CL are summarized.Finally,application strategies of CL in plant factory with LED light are put forward.
