摘要
在福建林学院苗圃,测定1年生杉木苗高、地径、根系的生物量及净同化率,分析研究1年生杉木实生苗干物质的生产、分配、积累及其器官生长的关系.结果表明,杉苗的生长初期苗高、地径生长和干物质积累缓慢;6~8月份杉苗体内干物质分配的重心是叶子;9~10月份苗木干物质分配重心转移到根、茎;11月份以后主要是根系的生长和茎干的充实.杉苗各器官的生物量与D2H存在着极紧密的幂函数相关关系.
In this paper, the net assimilation rate (Nar), height growth,and stem growth were measured periodically during the first year of growth of Chinese fir seedlings grown in wooden boxes under field conditions; and analysis was made of production and distribution of dry matter and of relationships of these indices with the organ growth in one year seedlings of Chinese fir.
