摘　　要：[Objective] The aim was to provide references for constructing compound ecological tea gardens. [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.[目的]为复合生态茶园的构建提供指导。[方法]在成龄生态茶园中分别选取在冬樱花、李树和木姜子树遮荫下的茶树,并与其相邻的未遮荫茶树作对照,对比年生长周期中不同树种遮荫对茶树叶片的光和、呼吸及净光和强度的影响。[结果]年生长周期中,在冬樱花、李树和木姜子树遮荫下的茶树叶片,其呼吸强度均极显著低于其对照茶树,净光合强度均极显著高于其对照茶树,而光合强度无明显规律;遮荫茶树叶片的净光和强度均是冬季高于春、夏、秋季。[结论]在保证茶树生理活动正常的前提下,降低无效的呼吸消耗,协调好光合、呼吸两大代谢的平衡,对茶树高产、优质有重要的意义。
