茶树系一种常绿长寿的木本植物,其寿有达八百岁者。但在栽培条件下,由于人们的强烈干预,显著缩短茶树的寿命,且越是远离根茎部的枝条衰退越快。然而,茶树为延续自己的生命,当地上部部分或全部衰退时,骨干枝的中下部、根茎部、乃至根部的不定芽或潜伏芽便抽生出新的生长势特强的枝条,以取代原有枝系,重新形成较旺盛的树势和生产能力,这就是茶树的自然更新。茶树更新修剪(台刈、重修剪等)正是利用茶树这种自然更新(或称再生)能力。这种修剪在树龄多大时进行为宜,我们认为 Tea tree is an evergreen longevity of woody plants, the life of up to eighty years old. However, under cultivation conditions, due to the intense human intervention, the life span of tea trees is significantly shortened, and the branches farther away from the roots and stems decay faster. However, tea tree is to extend their life, when the local part or all of the recession, the adventitious buds or latent buds in the middle and lower branches, rhizomes, and even the root of the trunk branches produce new branches with strong growth potential to replace the original ones Branches, re-formed more vigorous tree potential and productivity, this is the natural regeneration of the tea tree. Tea tree renewal pruning (Taiwan mow, heavy pruning, etc.) is the use of this natural refreshing tea tree (or regeneration) ability. This kind of pruning is appropriate when the age of the tree, we think
