摘要
对米槠树生物量空间结构特征研究表明,样株各器官干物质含量其组成顺序是:地上部分>地下部分,即主干与侧枝>粗根>叶子>中根>细根>小根>嫩枝。需给予充足的养分和水分供根系吸收和输送,以满足树体旺盛生长的需要。合理的树体空间结构对米槠优质丰产极其重要。
The study on biomass spatial structure of Castanopsis carlesii trees showed that the composition order of dry matters content of kinds of sample-plant organs was as follows： ground sectionunderground section that trunk and side branch coarse roots leaves middle roots fine roots small roots wands.It needs adequate nutrients and moisture for root absorption and distribution to meet the needs of the tree thrive.Reasonable spatial structure of trees was extremely important on high yield and quality of Castanopsis carlesii.
