摘要

为了编制在尼泊尔东部莫朗地区Belbari种植的竹的生物量表，从59个丛中共选择了153根茎。田间测量基部直径15cm处(D15)、茎秆垂直高度、茎秆鲜重、枝条和叶片。样品在加德满都实验室烘箱干燥。为了估算生物量，建立了基于干重和鲜重的回归模型。采用W = a + b × (D2 L)模型，根据烤炉干重，分别得到茎、枝、叶成分的R2值，分别为92、81和83%。以绿重为基础的茎和叶成分R2值分别为92和82%。枝条和叶片组分的R2值略低于茎。该公式可用于估算在类似立地条件下经管理的自然林分或人工林的竹材生物量。

Biomass estimation of Bambusa tulda grown at Eastern Terai, Nepal

With a view to prepare biomass tables of Bambusa tulda grown at Belbari, Morang district of Eastern Nepal, a total of 153 culms was selected from 59 clumps. Measurements of diameter at 15 cm of the base (D15), vertical height of the culm, green weight of the culm, branches and foliage were taken in the field. The samples were oven dried in laboratory at Kathmandu. To estimate the biomass, a regression model was developed on the basis of oven dry and green weight. The model used was W = a + b × (D2 L). Based on the oven dry weight, the R2 values were obtained for culm, branch and foliage components, which were 92, 81 and 83%, respectively. Similarly, R2 values for culm and foliage components on the basis of green weight were 92 and 82%, respectively. The R2 values obtained for branch and foliage components were slightly lower as compared to the culm. This equation could be useful in estimating bamboo biomass of managed natural stands or plantations in similar site conditions.

期刊介绍： The Journal of Bamboo and Rattan is a peer-reviewed scientific journal and provides a forum for scientific articles and reviews on all aspects of fast growing, multi-purpose pliable species. The scope of the journal encompasses income security, craft industry, small to medium size enterprises, industrial fibre and fuel. Articles related to natural distribution and conservation of species, genetics and biotechnology, harvesting and production systems, and environmental applications are also included, as well as papers on marketing and policy restraints in relation to bamboo, rattan and related species.
