通过对茶树留养叶光合速率与新梢生育、采摘、打顶、花蕾发育,以及留养叶的着生部位等关系的研究,结果表明,留养叶的光合速率随新梢生育而回升,在新梢长到1芽2叶时达到高峰,采摘能促进新梢萌发,扩大库容量,发挥留养叶的光合潜力,但休止前打顶会降低留养叶的光合效率;采摘时留养鱼叶的光合功能与正常叶相近,留2叶与留1叶光合源能力相近,主梢留叶比侧梢留叶光合能力强;着蕾可提高留养叶的光合速率,着蕾越多,增加越大。
The results showed that the photosynthetic rate of leaves was increased with the growth of new shoots, and the photosynthetic rate of shoots increased with the growth of new shoots, the growth of shoots, In the shoots grow to 1 bud 2 leaves reached its peak, picking can promote the shoots germination, expand the storage capacity, play the leaves of photosynthetic potential, but to stop before the top will reduce leaves photosynthetic efficiency; The photosynthetic function of the leaves was similar to that of the normal leaves. The photosynthetic capacity of the remaining 2 leaves was the same as that of the remaining 1 leaves, and the photosynthetic ability of the leave leaves of the shoot leaves was stronger than that of the shoot leaves. The buds could increase the photosynthetic rate of the leaves, , The greater the increase.
