摘要
围绕四川竹业资源培植需求,对8个丛生竹竹(品)种引种栽培3 a的生长性状变化和适应性进行分析。从立竹胸高断面积、竹丛篼幅及冠幅的变异系数变化,探讨了竹丛生长的营养空间拓展及其立地适应性表现。结果表明,丛生竹造林3 a的生长增殖已正常地表现出丛生竹无性系种群增长及结构动态,竹林已具备资源生态经济价值。
In this paper 8 sympodial bamboo species/varieties were investigated for their adaptability and variations in growth traits since 3 years of introduction. Adaptability o[ clumps to the cultivated site and their competition for vegetation spaces was analyzed based on the changes in coefficients o[ variation of breast-height basal area of culms and stump and crown dimensions of clumps. The results showed that over 3 years of vegetation the introduced bamboos could provide ecological and economic benefits which resulted from their normal multiplication pattern and population structure.
