【摘要】 衰老茶树的修剪更新引进茶树多种生物学性状(如新梢生育强度、分枝结构、叶片大小和树冠高宽度等)的变化.这些变化不仅因修剪强度而异,而且随时间的推移,其变化模式、速度在性状间会有所差异.有些性状的变化实质上是更新效应的衰减、复归.这种衰减与复归可作为决定更新修剪周期的科学依据.更多还原

【Abstract】 The regenerative pruning of weak and old tea could cause some changes ofbiological characteristics of tea plant,such as the intensity of growth and development ofnew shoots,the branching structure,the area of leaves and the height and the width ofcanopy and etc.The types and speed of changes are different between characteristics as timegoes on after pruning.The changes of some characteristics actually are the declining andrestitution of regenerative effects.The declining and restitution could be taken as ascientifical basis to decide the period of regenerative pruning.更多还原
