摘要
设施甜樱桃是我国北方重要的高附加值反季节生产落叶果树,种植面积和产业规模逐年增加。甜樱桃为喜光性短日照作物,冬春季节是设施樱桃的花芽分化、功能叶片发育、开花结果、果实发育、果实转色成熟等关键生育期,常受到设施内弱光寡照胁迫的影响,通过采取有效的光环境调控方法克服弱光寡照逆境对保障设施甜樱桃优质高产和提前上市至关重要。研究表明,人工补光、铺设反光膜和架设透光膜等方法强化树体冠层的光强、光质和光周期的立体空间保障,提高树体冠层整体光照截获利用能力。本文系统总结了设施甜樱桃冠层光环境特征及调控需求,概括了国内外在LED补光、透光膜和反光膜等光环境调控方法及其应用的增益作用,基于应急和常规补光需求提出了设施甜樱桃生产LED补光策略。
Facility sweet cherry is an important deciduous fruit tree with high added value in the north of China.Sweet cherry is a short-day and light-loving crop.During winter and spring,some key developmental stages,e.g.the flower bud differentiation,functional leaf development,flowering and fruiting,fruit development and fruit color-changing maturity of protected sweet cherry are often affected by low light stress.It is very important to overcome the low light and low illumination by adopting effective light environment control methods to guarantee the high yield and high quality of sweet cherry.Reports showed that the three-dimensional space guarantee of light intensity,light quality and light period of the tree canopy can be strengthened by supplementing artificial light,laying reflective film and erecting light transmission film,and the ability of light interception and utilization of the tree canopy as a whole can be improved.In this paper,the characteristics of light environment and the requirements of light environment control of sweet cherry canopy in facility are summarized.Based on the requirement of emergency and routine lighting,LED lighting strategy for sweet cherry production in facility was proposed.
