花卉生产中花期调节补光灯配光方案设计研究(英文)

Lamp Distribution Design for Adjustment of Florescence in Floral Production

[目的]介绍各种光源特性,筛选最佳大棚花卉生产补光灯配光方案。[方法]选用菊花切花生产为试材,采用白光复合光照,在大棚里配置高压钠灯、荧光节能灯、LED农业专用灯,根据3种灯具的光形特点和植物生长需求,进行实地测试,比较各种灯具的实际应用效果。[结果]结果表明,LED新型光源在整灯实际应用中节能效果明显优于其他两种灯具;LED方形灯具设计呈蝙蝠翼光形配光曲线最有利于温室实施有效布灯。[结论]LED农业专用补光灯优于目前最常用的钠灯,具有节能易布灯等特点,具有实际推广应用价值。

[Objective] The aim was to introduce characters of light sources and select the optimal lamp scheme for floral production in greenhouses. [Method] With chrysanthemum cuttings as materials, HPSL, energy-saving fluorescent lamp, and LED agricultural lamp were made use of to carry out field tests in order to compare practical effects according to light characters of different lamps and plant growth de-mands. [Result] The results show that LED lamp performed the best of the three in practical use. LED square lamp designed in bat-wing shape would be the most ben-eficial for lamp distribution in a greenhouse. [Conclusion] LED agricultural lamp is the most popular currently, for it is energy saving and easy for operation.
