[Method] In an ecological adult-tea garden, teas shaded by Prunus cerasoides, Prunus L., and Litsea pungens were selected and the teas without shades were taken as a control in order to explore effects of tree shading on photosynthesis, respiration and net photosynthetic intensities. [Result] In a growth cycle of one year, for teas shaded by Prunus cerasoides, Prunus L., and Litsea pungens, respiration intensity was significantly higher than that of the control; net photosynthetic intensity was extremely significant higher; photosynthesis intensity showed none rules. Both of net photosynthetic rate and intensity kept higher in winter of shaded teas. [Conclusion] It is of significance for high-yielding and high-quality teas to reduce respiration consumption and coordinate between photosynthesis and respiration given that tea grows well.展开更多
