摘要
对黎平县9年生红皮树母树林的生长和生物量进行了调查分析,结果表明:9年生红皮树母树林平均树高、地径、枝下高、冠幅、单株材积分别是5.26m、13.82cm、0.59m、3.59m、0.0576m^3。标准木生物量为33.46kg,地上部分30.15kg,地下部分3.31kg,母树林林分生物量为27.8721 t·hm^(-2)。各器官生物量大小表现为树干>枝>根>叶,各器官含水率大小表现为叶>根>枝>树干。
In this paper,the growth situation and biomass of 9 years old seed production stand of Styrax suberifolius were investigated in liping county. The results showed that the average height,ground diameter,height under branch,crown width,individual volume were 5. 26 m,13. 82 cm,0. 59 m,3. 59 m and 0. 0576m^3 respectively. The biomass of standard tree was 33. 46 kg,in which the aerial part for 33. 15 kg and 3. 31 kg in roots,the stand biomass was 27. 8721 t·hm-2 of each organ,the biomass was ranked as trunk branch root leaf,and water content was ranked as leaf root branch trunk.
