茶树原生长在自然系统中的林荫覆盖之下,在人工栽培茶树以前,纯属一种自然物。然而茶树的生长发育与原始生态型的遗传特性及生态环境是密切联系的,生态条件的改变,必然影响到茶树生理活动和内在习性的改变,从而影响到茶叶的产量和品质。然而, The original growth of tea tree in the natural system of covered under the tree before the artificial cultivation of tea, purely a natural thing. However, the growth and development of tea tree is closely related to the genetic characteristics and ecological environment of the original ecological type. The change of ecological conditions will inevitably affect the physiological activities and intrinsic habits of tea plant, thus affecting the yield and quality of tea. however,
