摘要
分别在南京、山东潍坊、北京3个地区对铺地竹的竹鞭及鞭侧芽的生长发育规律、分布规律进行了调查研究,结果表明:铺地竹表现出明显的混生特性;且是一种典型的浅鞭系竹种,其竹鞭、竹鞭上的侧芽大都集中于10cm以上深的土层中;2～3a鞭是铺地竹发笋的主要竹鞭,5a鞭开始老化。据此,移栽该竹种时要选择2～3a的竹鞭,埋鞭不易过深,对于5a以上的竹林要及时挖掉老鞭和竹兜。
The growth regularity and the distribution of rhizome and lateral buds of Arundinaria argenteostriata were investigated in Nanjing, Weifang, and Beijing in this paper. The results showed that Arundinaria argenteostriata was in characteristics of the mixed-growth, and its rhizome and buds were mainly distributed in the depth of 10 cm soil. The most bambooshoots were generated from the two or three-year-old rhizomes, and the rhizomes were aging gradually when 5 year-old. Therefore the two or three-year-old rhizomes were the best selection when transplanted. For the more than five-year-old bamboo forest stands, the aging rhizomes would be eliminated timely.
