花卉生产中花期调节补光灯配光方案设计研究

The Light-Shaped Design Research of Lamp for Adjusting the Florescence of Flowers

[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 ] To screen the optimal light-shaped design of lamp for adjusting the florescence of flowers. [ Method I Selecting chrys-anthemum cuttings as material, using white composite light, allocating HPS, energy-saving fluorescent lamp and LED agricultural lamp, the field test was conducted to compare the actual application effect of three lamps according to light shape characteristics and plants growth de- mands. [ Result] The results showed that LED square shape lamp with batwing light distribution curve is beneficial for greenhouse. [ Conclu-sion ] LED agricultural lamp is superior to the most commonly used HPS, with characteristics of energy-saving and easy operation, and has ex-tensive application value.
