为解决华南地区冬春季节蔬菜育苗缺光现象,采用不同比例红蓝光组合的LED灯(红∶蓝=7∶3,7R3B;红∶蓝=8∶2,8R2B;红∶蓝=9∶1,9R1B)进行补光,以自然光为对照,探讨不同光质的LED灯补光对苦瓜、豆角、茄子和辣椒育苗的效应.结果表明:不同的红蓝光组合LED灯补光对苦瓜、豆角、茄子和辣椒育苗具有一定的促进作用,其中对苦瓜幼苗的鲜重、地下部分干物质积累、叶绿素含量以及根系活力具有显著的促进效应;对豆角幼苗地下部分干物质积累、叶绿素含量以及根系活力具有显著的促进效应;对辣椒和茄子的形态指标和生理指标均有显著的促进效应,辣椒育苗的最适壮苗光源为9R1B,茄子育苗的最适壮苗光源为8R2B.
