光伏板遮阴对大叶种茶树叶片光合特性和产量的影响
Effects of Photovoltaic Panel's Shading on the Photosynthetic Characteristics and Yield of Camellia sinensis
摘要
Abstract
[Objective]The research aimed to explore the effects of photovoltaic panel's shading on the photosynthetic characteristics and yield of Camellia sinensis,and explore the appropriate shading degree of photovoltaic panels,so as to provide the scientific and theoretical basis for the tea-photovoltaic complementary cultivation mode.[Method]The relative content of chlorophyll,chlorophyll fluorescence parameters and tea yield of C.sinensis were compared among five kinds of light environment.[Result]Photovoltaic panel's shading had significant effects on the relative content of chlorophyll,fluorescence parameters and tea yield of C.sinensis.Compared with the non-shading treatment(CK),the initial fluorescence value(Fo),maximum fluorescence value(Fm),the actual photochemical quantum yield of PSⅡ(Phi2),the quantum yield of non-regulating energy dissipation(PhiNO),and the steady-state fluorescence value(Fs)in each photovoltaic panel's shading treat-ment all significantly increased(P＜0.05).Compared with the non-shading treatment(CK),the non-photochemical quenching coefficient(NPQ),photochemical quenching coefficient(qL),relative electron transfer rate of PSⅡ(ETR),and quantum yield of regulated energy dissipation(PhiNPQ)in each photovoltaic panel's shading treatment all significantly decreased(P＜0.05).[Conclusion]Moderate shading can alleviate the damages of strong light and high temperature on the photosynthetic system of C.sinensis in summer and autumn,and increase the chlorophyll content of leaves and tea yield,which has important economic value for developing tea resources in the summer and autumn.The tea-photovoltaic complementary mode should be promoted in Pu-er region of Yunnan Province,the shading degree of photovoltaic panels should be 30%-40%.关键词
