温室屋面光伏组件对温室微环境及作物净光合速率的影响——以草莓温室为例
Journal of Yunan Normal University(Natural Sciences Edition)(2021)
Abstract
以"京藏香"草莓为实验作物,研究温室南面屋面安装光伏组件对温室微环境以及草莓叶片净光合速率的影响.结果 表明:光伏温室内太阳辐射日均值相比普通温室降低了47.3%,光合有效辐射PAR降低了68%.光伏温室草莓叶片净光合速率Pn日均值为3.53μmol·m-2· s-1,高于普通温室内草莓叶片Pn日均值3.34 μmol·m-2· s-1.在普通温室中,草莓叶片光能利用率(LUE)仅为光伏温室的26.3%,但草莓叶片净光合速率随空气温度、空气湿度和PAR变化的幅度均高于光伏温室.
