雖然目前之研究大多顯示，茶樹在長期一定程度林木遮陰下，產量會顯著較低，但是因 為茶樹具有耐陰之特性，同時遮陰後品質會顯著提高，因此應有可能在適度之林木與茶樹混植 下，獲得一定程度之經濟生產。本文先回顧混茶林業及林木遮陰下，茶樹之生長與生產反應，再 論述茶樹之光合作用特性，及其可能在混林狀態下之反應，評估混茶林業之可行性。

Research indicates that tea bush growth and yield are inferior under long-term forest heavy shading. However, evidence further shows that it’s possible to establish a forest-tea production system by quality improvement, because of shading tolerance characteristic. So, in proper shading, forest trees and tea bushes intercropping could make a forest-tea production system that might attain economic standard. This article has reviewed forest-tea production system and tea growth yield in response to shading of forest condition. Additionally, discussion of photosynthesis characteristics and estimation of the possibility of forest-tea production system in Taiwan are presented.
