【摘要】 研究了丛生竹种硬头黄竹的生物量结构,并建立各器官生物量与胸径和竹高的拟合模型。结果表明:(1)硬头黄竹各器官生物量在单株上的分配为秆79.54%,枝7.51%,叶4.23%,根1.71%,蔸7.01%;其中竹秆所占的比例最大,远超过苦竹等其它竹种。(2)硬头黄竹各器官生物量与胸径(DBH)有较好的相关性,其中胸径(DBH)与鲜秆质量(W1)、全株质量(W4)的拟合模型分别为W1=435.61 D1.887 5和W4=558.787 D1.895 3,可以较准确地估算出各器官的生物量大小。更多还原

【Abstract】 The biomass structure of Bambusa rigida Keng was studied in this paper.The regression models of each biomass component based on DBH and culm height were constructed.The results were as follows:(1)The biomass allocation among culm,branch,leaf,root,stump were 79.54%,7.51%,4.23%,1.71%,7.01% respectively,of which,the culm accounted for 79.54% and much higher than that of Pleioblastus amarus Keng and others.(2)Various components were highly correlated with DBH and culm height.The model of fresh culm weight(W1) and total fresh weight(W4) based on DBH were W1=435.61 D1.887 5 and W4=558.787 D1.895 3 respectively.更多还原
