摘　　要：为探讨不同LED光源对甘蓝幼苗生长发育的影响,以荧光灯光源为对照,研究了红光和全光谱白光2种不同LED光源照射下的甘蓝幼苗生长情况。结果表明:不同的光质处理对甘蓝幼苗生长有显著影响,相较于荧光灯光源,LED全光谱白光光源照射下的甘蓝幼苗植株矮壮,茎较粗,根系发达,干物质积累多,壮苗指数高;而红光照射下的甘蓝幼苗植株高大,地上部发达,叶色较深,叶片较大。研究认为LED全光谱白光照射(T2处理)较适合甘蓝育苗。In order to explore the effects of different LED light sources on the growth and development of cabbage seedlings,the growth of cabbage seedlings under red light and full spectrum white light were studied with fluorescent light source as control.The results showed that different light quality treatments had significant effects on the growth of cabbage seedlings.Compared with the fluorescent light source,the cabbage seedlings irradiated by LED full spectrum white light source had shorter and stronger plants,thicker stems,developed roots,more dry matter accumulation and higher seedling index,while the cabbage seedlings irradiated by red light had higher plants,developed shoot,deeper leaf color and larger leaves.It was suggested that LED full spectrum white light irradiation(T2 treatment)was more suitable for cabbage seedling.
