LED植物补光灯试制及其大棚草莓补光栽培效果分析

Trial Production of LED Plant Supplementary Light and Analysis of Its Effect on Strawberry Supplementary Light Cultivation in Greenhouse

设计试制了红光占比不同的LED大棚草莓补光灯灯管;研发了一体式的LED灯密封结构,适应草莓种植大棚的特殊结构和潮湿环境。在草莓的开花与结果期进行了LED大棚草莓补光灯的补光效果试验对比测试。初步分析表明:补光增加了果实大小和产量;显著影响果实的总糖、总酸和固形物含量,改善了果实的风味品质;且红光占比较高的补光效果更显著。

The LED greenhouse strawberry supplementary light tube with different proportion of red light was designed and manufactured.The integrated LED lamp sealing structure was developed to adapt to the special structure and humid environment of strawberry planting green houses.In the flowering and fruiting stage of strawberry,the effect of the strawberry supplementary light in LED greenhouse was tested.The results indicate that supplementary light increases fruit size and yield,affects the contents of total sugar,total acid and solids significantly and improves the flavor quality.Moreover,the effect of supplementing light with higher proportion of red light is more remarkable.
