杉木(Cunninghamia lanceolata)是我国南方主要的造林树种。1953年6月间中国科学院植物研究所和有关机关组成的广西植物调查队,对于兴安县华江区杉木的生长和环境的关系,亦作了附带的调查。曾在千祥乡、锐伟乡分别于竹、杉混交和杉木纯林内,选择不同环境的7小区,测量树高、胸径,然后每区选出样木1株,其中中庸木6株,一级木1株;应用树干解析法依司马利(Smalian)区分求积式以每1米为1区分,截取圆板,测定计算其各龄阶的生长量,观察其生长情况和环境的关系。期望在对工作方法上作一初步探讨。因为工作时间短促,所选样木较少,对于分析有关问题,如有错误之处,希读者加以指正。
Cunninghamia lanceolata is the main afforestation species in South China. Guangxi Plant Investigation Team composed of Institute of Botany, Chinese Academy of Sciences and relevant agencies in June 1953 conducted an incidental investigation on the relationship between the growth and environment of Chinese fir in Hujiang District of Xing’an County. In Qianxiang Township and Ruiwei Township, 7 communities of different environments were selected in the mixed community of bamboo and fir and pure Chinese fir plantations, and the tree height and DBH were measured. Grade 1 wood; using tree trunking method according to Smalian differentiation Quadrature method for each 1 meter for 1 distinction, intercepting disk, measuring and calculating the growth of each stage, to observe the relationship between its growth and the environment. Expect to make a preliminary discussion on the working methods. Because of short working hours, the sample is less selected wood, for the analysis of the relevant issues, if any errors, readers hope to correct.
