不同光质补光对日光温室黄瓜产量与品质的影响

The effects of different light qualities on cucumber fruit quality and yield in greenhouse

摘要: 验采用不同的光质灯(蓝光、红光、UV-A、UV-B)对温室内黄瓜进行定时补光，研究不同补充光质对黄瓜果实Vc、蛋白质、还原糖含量及产量的影响。结果表明UV-B、红光条件下黄瓜Vc含量较UV-A与蓝光高；各处理蛋白质含量顺序为蓝光＞UV-A＞UV-B＞红光；蓝光照射下还原糖含量较红光、UV-A与UV-B高；日光温室内补充UV-A可明显地增加黄瓜的产量。

Abstract: The effects of different light qualities(blue, red, UV-A, UV-B)on the quality of cucumber fruit growing in solar greenhouse were investigated and the contents of vitamin C, protein, and deoxidized sugar were measured. The results show that the vitamin C content of cucumber fruit under UV-B and red light is higher than that under UV-A and blue light; the contents of protein and deoxidized sugar in fruit under blue light are the highest among these under all the treatments. Under UV-A light the yield is higher than that under any other treatments.
