Research on individual bamboo biomass and timber physical structure indicated that the allocation of Guadua amplexifolia biomass to branch is higher than moso-bamboo evidently. Root shoot ratio is larger than other sympodial bamboo, so it can be considered as a good breakwind plant because of developed root and branch. Every modularity biomass above ground had significant positive correlation with basal diameter and total height, it can simulated with allometric model. The culm had large relative wall thickness and low moisture content, so it can be cultivated as fine timber-used bamboo.
通过对Guadua amplexifolia现存单株生物量结构和竹材物理结构研究,结果表明:地上部分生物量在枝条上的分配比例高于相同径级毛竹,根冠比较其他丛生竹种大,具有发达的地下根系且易形成密集林分,是良好的防风植物材料;地上部分各器官生物量与地径、全高均呈显著的正相关,可以用相对生长模型进行模拟;竹秆有较大的相对壁厚和较低的含水率,可以作为良好的材用竹种进行培育。
