摘要
通过对移栽母竹新造毛竹林竹鞭生长的调查,得出造林当年新发竹鞭直径1.47cm,鞭长0.967m,鞭节长3.16cm,断梢率最低(9.167%),第二年新鞭鞭径1.918cm,鞭长2.170m,鞭节长4.48cm,断梢率最大(73.792%),第三年鞭径为2.042cm,鞭长1.755m,鞭节长4.45cm,断梢率52.667%.各年度竹鞭鞭径、鞭长、鞭节长和断梢率均存在显著差异.常规密度(495或630株/hm2)下,移栽母竹新造毛竹林两年即可实现地下郁闭(抽鞭8.97条/株,竹鞭扩展直径达6.274m).
Through investigating on rhizome wood growth regularity of new planted Phyllostachys edulis , this paper reported that from the first year to the third year the diameter of rhizome wood were 1 47cm,1 92cm and 2 04cm respectively, the length of rhizome wood were 0 97m,2 17m and 1 76m respectively, the length of rhizome joint were 3 16cm,4 48cm and 4 45cm respectively, the end breakage rate of rhizome wood were 9 2 percent,73 8 percent and 52 7 percent; that underground closure of new planted Phyllostachy edulis stand could accomplish under routine density in two years Those conclusions provided directions for density determination of new planted Phyllostachy edulis stand
