摘要
茶秆竹竹鞭绝大部分分布在 0～ 30cm土层中。竹鞭生物量与鞭长、鞭径呈正相关。壮芽比例是 1龄竹鞭的较少 ,随着鞭龄加大而增多 ,然后又迅速减少。笋芽多长在 2～ 3龄竹鞭上。竹鞭划分应以 1龄为幼龄鞭 ,2～ 3龄为壮龄鞭 ,4龄为中龄鞭 。
The rhizomes of Pseudosasa amabilis are mostly distributed in soil,whose depth ranges from 0～30 cm,and the biomass of rhizome is correlated positively with the length and the diameter of rhizome.The proportion of the germinations is less on one year old rhizome,and then increasing with the age of rhizome,finally decreases sharply again.Most of shoots emerge on two or three year old rhizomes.The division of rhizome is as follows:one year old rhizome is immature rhizome,two or three year old rhizome is strong rhizome,four year old rhizome is middle aged rhizome,and over four years old,it is aged rhizome.
