摘要
[目的]探明LED光源对温室甜椒产量和品质的影响。[方法]以甜椒为试验材料，在其不同生育阶段对其进行LED灯补光，观察其产量及品质变化。[结果]与对照相比，3个补光处理均可大幅提高甜椒的单果质量、商品率、产量，同时还可提高甜椒维生素C含量、降低其硝酸盐含量。[结论] LED灯补光有利于甜椒产量提高和品质改善，以从苗期开始补光效果最好。
Abstract
Objective] To research the effects of LED supplementary lighting on the yield and quality of pimiento in greenhouse.[Method] With pimiento as the test material, LED supplementary lighting was carried out in different growth periods.The yield and quality changes of pi-miento were observed.[ Result] Compared with the control, three supplementary lighting treatments greatly enhanced the single fruit quality, commodity rate and yield of pimiento, enhanced the vitamin C content in pimiento, and reduced the nitrate content.[ Conclusion] LED sup-plementary lighting is conductive to improving yield and quality of pimiento, especially at seedling stage.
