LED红蓝绿光质对两种草莓生长和产量的影响

Effects of Red Blue and Green Light from Red and Blue LEDs on Growth and Yields of Two Cultivars of Strawberry

在环境可控的人工光植物工厂内,以“章姬”和“白雪公主”草莓品种为材料,利用LED精准调制光源,探究了红蓝比3∶1和4∶1以及红蓝绿比6∶2∶1和32∶8∶5这4种光质对两个品种草莓生长和产量的影响。结果表明,含绿光光质提高了两种草莓产量,而生长指标没有显著差异,对草莓花期的影响存在品种差异。红蓝光和红蓝绿光的4个处理都能够使草莓正常生长,其中红蓝绿比32∶8∶5光质处理下对草莓生长和产量的提升最高。

In an environmentally-controlled plant factory with artificial light,the effects of four light qualities(red:blue 3:1 and 4:1,red:blue:green 6:2:1 and 32:8:5)on growth and yields of two cultivars(Zhangji and Baixuegongzhu)of strawberry were investigated.The results showed that light qualities with green light improved yields of two strawberry cultivars,while growth indices were not influenced.Two cultivars could grow normally under four light qualities,and red:blue:green 32:8:5 was the best light quality for strawberry production for both cultivars in terms of yield.
