为了探明茶叶产量和品质形成的特殊生境及其光合生理机制,在中国科学院长沙农业环境观测站利用3种间种乔木模式(S_1:桂花树-茶树,S_2:乐昌含笑-茶树,S_3:桂花树-乐昌含笑-茶树)与纯茶园(CK)建成了4种典型生境,比较研究了这些特殊生境下茶叶产量与品质形成的光合生理生态特性.结果表明:生境S_1、S_2、S_3显著降低了茶树叶片温度(TL) 、光合有效辐射通量(PAR),叶片净光合速率(P_n ) 、蒸腾速率(T_r )和气孔导度(g_s )的日均值,显著降低了茶叶茶多酚总含量.生境S_1、S_2、S_3显著提高了叶室相对湿度(RHS) 、茶叶氨基酸总含量,显著提高了茶叶产量和品质,并且S_3>S_1>S_2>CK,其中生境S_1和S_3的茶叶适...

To understand photosynthetic mechanism of tea yield and quality, an experiment was conducted with four different typical habitats, including three intercropping patterns (S1:Osmanthus-Tea, S2:Michelia-Tea, S3:Osmanthus-Michelia-Tea) and a control (CK) at Changsha Agricutural Observation Station of Chinese Academy of Sciences. The photosynthetic physiological and ecological characteristics of tea yield and quality were examined. The results showed that the habitats S1, S2, S3 reduced the leaf temperature (TL), photosynthesis active radiation flu...
