摘　　要：随着我国光伏产业的快速发展,利用光伏板下空间发展农业产业成了新课题。香草兰是名贵的天然食品香料作物,具有喜荫的习性,发展光伏下种植香草兰可以增加较高的经济效益和保护水土流失。为了研究光伏下种植香草兰叶片光合特性的变化,通过田间试验,比较光伏下种植香草兰、槟榔间作香草兰和荫棚种植香草兰3种不同模式、不同冠层香草兰叶片的光合特性差异。结果表明,通过净光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)、胞间CO2浓度(Ci)和叶绿素(Chl)含量等指标值对比,光伏下种植香草兰的各项指标低于槟榔间作香草兰,但高于荫棚种植香草兰,且差异性显著。在遇到较强光照时,香草兰叶片会通过降低净光合速率来保持正常生长,说明香草兰虽然是喜荫作物,但是短时间的强光照射比长时间的弱光照射更适合提高香草兰的光合作用。研究可为光伏下种植香草兰模式的推广应用提供理论依据。With the swift advancement of China's photovoltaic industry,the utilization of the space beneath photovoltaic panels for the development of agricultural industries has emerged as a novel topic.Vanilla is a valuable natural food-flavoring crop that prefers shade.Developing the cultivation of vanilla under photovoltaics can increase economic benefits and prevent soil erosion.To study the changes in leaf photosynthetic characteristics after cultivating vanilla under photovoltaics,a field experiment was conducted to compare the differences in the photosynthetic characteristics of vanilla leaves under three different models and canopies:cultivating vanilla under photovoltaics,intercropping vanilla with betel nut,and planting vanilla under shade.The results showed that based on the indicators such as net photosynthetic rate(Pn),stomatal conductance(Gs),transpiration rate(Tr),intercellular carbon dioxide concentration(Ci),and chlorophyll content(Chl),the values of cultivating vanilla under photovoltaics were lower than those of intercropping vanilla with betel nut,but higher than those of planting vanilla under shade,and the difference was significant.When exposed to strong light,vanilla leaves reduced their photosynthetic rate to maintain normal growth.This indicated that although vanilla prefered shade,short-term exposure to strong light was more beneficial for enhancing its photosynthesis compared to long-term exposure to weak light.This finding provided theoretical support for the promotion and application of the cultivating vanilla under photovoltaic model.
