苦竹;林分结构;竹秆;竹枝;竹叶;生物量
摘  要：
为了给苦竹林丰产培育提供理论依据,在笋材兼用集约经营苦竹林中进行了林分结构和地上部分器官生物量调查,结果表明:立竹全高、枝下高是立竹胸径的从属因子;随着立竹年龄的增大,地上部分器官含水率降低,1~2 a立竹器官含水率竹叶>竹枝>竹秆;1~2 a单株立竹竹秆、竹枝、竹叶生物量与立竹胸径呈线性或二项式关系,1 a立竹竹秆>竹叶>竹枝,2 a立竹竹秆>竹枝>竹叶,随着立竹年龄的增大,竹秆生物量比例降低,竹枝、竹叶生物量比例提高;1~2 a立竹和林分的器官生物量比例竹秆>竹枝>竹叶,随着立竹年龄的增大,竹秆、竹枝、竹叶生物量显著提高。

摘  要：
In order to promote fertility cultivation of Pleioblastus amarus,the bamboo forest structure and above ground biomass of P.amarus for bamboo shoot and timber were investigated,the results showed that bamboo stem total height and height under first branch were hypotaxis factors of diameter at breast height(DBH).The water content of above ground organ decreased with increasing bamboo stem age,for 1-2 a bamboo stem organ,water content were in the order of leaf>branch>culm.The relationship were linear or binomial between culm,branch and leaf biomass of 1-2 a bamboo stem with bamboo stem DBH,1 a bamboo biomass was culm>leaf>branch,but 2 a bamboo biomass was culm>branch>leaf,culm biomass proportion decreased,branch and leaf biomass proportion increased with increasing bamboo stem age.The organ biomass proportion of 1-2 a bamboos were culm>branch>leaf.Culm,branch and leaf biomass increased notably with increasing bamboo stem age.
