摘要
通过对黄甜竹(Acidosasa edulis)丰产林16块标准地地下鞭根系统和地上部分生物量的调查分析,结果表明,在0～20cm土层中的壮龄鞭在这一层总的鞭长、鞭重中所占的比例最大,而20～40cm土层中的壮龄鞭在这一层总的鞭长和鞭重所占的比例均为居中,老龄鞭在鞭长和鞭重中所占的比例最大,幼龄鞭在鞭重中所占的比例最小,鞭径也最小;黄甜竹竹杆部分的生物量稍大于枝叶部分的生物量,分别占地上部分生物量的55.59%和44.41%。
Investigation and analysis were conducted on rhizome system and aboveground part biomass of Acidosasa edulis in 16 sample plots of plantation in Lishui, Zhejiang province. The result showed that adult rhizomes occupied the most part of length and weight at 0-20 cm soil layer, while medium at 20-40 layer where old rhizome took the most part of length, internodes, and young rhizome the heaviest. Biomass of stem was a litter larger than that of branch and leaf, taking respectively 55.59% and 44.41%.
