一、引言茶树成龄期,它的地上部,即所谓冠层,形成了较稳定的树体结构。即使它的上层每年有节奏地发生新梢,呈现季节性和年周期性生长动态,然而茶树不同品种,各有其周有的株型特征。这些特征既是不同品种对生态环境的适应,也反映出茶树品种生理代谢的差异。因此,研究茶树不同品种冠层枝干结构,是研究茶树株型的重要组成之一,它有助于我们从形态结构深入到生理代谢来揭示茶树不同品种产量和品质形成的规律,为提高茶树光能的利用率及筛选优良品系提供理论依据。
I. Introduction Tea tree age, its aerial part, the so-called canopy, formed a more stable tree structure. Even though its upper layer rhythmically emerges annually, showing the seasonal and annual growth dynamics, however, different varieties of tea tree each have their own plant type characteristics. These characteristics not only adapt to the ecological environment of different varieties, but also reflect the difference of physiological metabolism of tea varieties. Therefore, studying the canopy structure of different varieties of tea tree is one of the important components to study the plant type of tea plant. It is helpful for us to reveal the law of yield and quality of different varieties of tea plant from its morphological structure to physiological metabolism. Light utilization and selection of good lines to provide a theoretical basis.
