摘要
蓝莓是一种新兴的世界性多年生小浆果树种,果实营养价值高,品种丰富,设施反季节栽培效益高。我国设施蓝莓生产面积逐年扩大,南方和北方均有大面积种植,设施盆栽基质栽培已成为发展方向。但是,受恶劣天气(阴雨雪雾霾)、设施遮挡和保温措施的影响,设施蓝莓生产存在严重的光照不足问题,尤其是在冬春季节光照不足导致的产量品质问题十分严重。LED补光是解决设施蓝莓光照不足的最直接方法,按照最佳光谱、适宜光强和光周期的原则来制定补光方案,保证蓝莓光环境需求,高产优质提前上市。本文综述了我国设施蓝莓种植现状,分析了光照不足的原因,提出了LED补光方案设计原则。
Blueberry is a new kind of world-wide small perennial fruit tree with high fruit nutritional values,rich varieties and high production benefit,which is suitable for off-season cultivation in facilities.Facility blueberry production area expanded gradually in both the South China and the North China,and the pot substrate cultivation has become the development direction nowadays.However,due to the facility shade and heat preservation measures,there are serious problem of lacking light(intensity and photoperiod)in facility blueberry production,especially in winter and spring.LED lighting is the most direct method to solve the facility blueberry light shortage.We can design the lighting scheme with best spectrum,appropriate light intensity and photoperiod to optimize light environment for blueberry growth,flower and fruit development.Then,high-yield and high-quality as well as marketing ahead of time will be achieved.This paper summarized the present situation of blueberry planting in China,analyzed the reasons of insufficient illumination,and put forward the design principles of LED light scheme.
