摘  要:
以城市景观绿化红竹林为对象,对立地条件、初植密度相同,不实施人工干扰,高密度全梢竹一次成景栽植的2种造林年份(2003年、2005年11月)红竹林2007-2009年的新竹数、新竹胸径和枝下高、全高进行了调查。结果表明:造林后前3个出笋成竹年新竹数无显著差异,第4个出笋成竹年新竹数显著下降,并呈逐年降低趋势;随着造林年限的延长,新竹胸径逐年增大,相邻年际间新竹胸径增幅降低。造林后前3个出笋成竹年新竹胸径差异显著,从造林后第4个出笋成竹年开始,新竹胸径趋于相对稳定;立竹枝下高、全高是立竹胸径的从属因子,不同造林年份试验林不同年度相同胸径的立竹枝下高无显著差异,立竹全高总体上也无显著差异。

摘  要:
Investigations in 2007 and 2009 were conducted on Phyllostachys iridescens plantations for urban landscape with the same site conditions and planting densities in 2003 and 2005 in Longyou,Zhejiang province.The results showed that there was no significant difference of amount of new bamboo in the first three years after different plantations,but shooting was significant declined at the fourth year and then decreased gradually.With the years of plantation,DBH of new bamboos increased year by year,and tended to be stable from the fourth year after plantation.Total height and clear bole height were subsidiary factors of DBH,and no significant difference was found of different plantations.
