红、蓝双通道滤光膜对植物生长的影响

Effect of dual-channel red/blue optical filter on the growth of plants

为了评估新型光伏农业系统中在滤光膜下的植物生长是否会受到影响,在玻璃温室条件下,采用土培盆栽的方法种植生菜(Lactuca sativa)、黄瓜(Cucumis sativus)和空心菜(Ipomoea aquatica),设置植物上方有膜和无膜两组进行对照,测试分析了滤光膜对不同植物生长与品质的影响。结果表明,与无膜处理相比,滤光膜处理的植株在形态、光合和品质指标上均表现更加优异,表明在滤光膜下的植株生长更好,品质更优。

To evaluate the effect of optical filter on the growth of plants in new photovoltaic agricultural system,lettuce（Lactuca sativa）,cucumber（Cucumis sativus） and water spinach（Ipomoea aquatica） were grown in the pot in the glass greenhouse.Two groups were designed to contrast with one under the optical filter and the other blank,and the effect of optical filter on the growth and quality of different plants were tested and analyzed.The results suggest that compared to the blank group,the plants under the optical filter have better performance in morphological,photosyntheticand quality indexes,and the plants under the optical filter grew faster and had better quality.
