茶树是一种采收幼嫩芽叶作为饮料的多年生经济作物,其产量的90—95％来自光合作用的产物。单位地面上茶树光合作用所能利用的光能数量的多少,与单位面积上茶树的绿色面——光合面积的大小密切相关。光合面的大小用叶面积指数表示,并作为衡量茶叶产量和茶树生育水平的重要指标之一。研究资料表明,茶树的光合面积只有在适宜的指标范围内,茶
Tea tree is a perennial cash crop that harvests young shoots as a beverage, with 90-95% of its production coming from photosynthesis products. The amount of light energy available for tea plant photosynthesis on a unit surface is closely related to the green area of a tea plant per unit area - the area of photosynthesis. The size of photosynthetic surface is expressed by the leaf area index, and is used as one of the important indexes to measure tea yield and tea fertility. Research data show that tea tree photosynthetic area only within the appropriate range of indicators, tea
