| 摘 要： | 在对上海市固氮植物资源调查的基础上,选定29种有一定固氮能力的树种。以海滨木槿为对照,测定其年相对高生长量、年相对径生长量、固氮效率,并对生长量与固氮效率的相关性进行分析。分析结果表明:树种间测量指标差异显著;固氮效率与植物生长存在较强正相关性(相关系数0.839**、0.707**),固氮效率越高的植物,其相对高、径生长量越大。 |

| Abstract: | Based on the survey of N-fixing trees in Shanghai,29 kinds of trees with certain N-fixation capacity were chosen to conduct this experiment,Hibiscus hamabo was taken as the control tree,and their relative stem height,diameter growth and nitrogen-fixation efficiency were determined.Then,correlation analysis was carried out between growth quantity and N-fixation efficiency.The results showed that there were significant differences in tested parameters among different kinds of trees;but growth quantity was hig... |
