摘　　要：通过对嫁接茶树分枝习性的观察 ,发现嫁接茶树年生长量大 ,分枝数多 .嫁接的第二年 ,枝梢年生长长度可达 70～ 10 0 cm,分枝数、分枝长、分枝茎粗等都超过台刈茶树 ,因而提出对嫁接茶树的初期树冠培养 ,应有别于以往对幼年茶树一年定剪一次的培养模式而实行一年定剪二次 ,分别在春前和 9月上、中旬进行 ,春末、夏秋可适当打顶采摘以控制树高 。Composite tea plant features great annual growth and increase in the number of shoots. In the second year after grafting, the annual length of sprout ranges from 70 to 100 cm. The number, length and thickness of shoots all exceed those of the collar pruned ones, which can play a positive role in developing the framework of crown canopy. According to this, in terms of crown construction in the infancy of the tea plant, there must be some differences between composite tea plants and young tea plants which has just one frame pruning per year. Instead, to the composite tea plant, it should be exerted twice a year. Pre spring, early and mid September are the suitable phases for doing it. Besides, in order to control height and promoter crown to extend in cross direction (breadthwise), properly top plucking could be helpful if taken at the end of spring and in summer and fall.
