| 摘 要： | 选择上海29种固氮树种,对固氮效率、叶片(鲜叶、落叶)含氮量及年相对径、高生长量进行测定。通过对以上指标及氮输出率的综合评价分析,筛选出长势良好且对土壤改良有一定功效的树种。结果表明:种内各测量指标差异不明显,种间则差异显著;固氮效率与鲜叶含氮量及高、径年相对生长量具有较强正相关性(相关系数为0.888**、0.839**、0.707**),均达到极显著水平;非豆科树种江南桤木、胡颓子、花叶胡颓子及豆科树种常春油麻藤、紫藤、染料木固氮效率、落叶含氮量较高,有利于改良土壤,增加土壤肥力,是良好的落叶肥田植物。 |
| 关 键 词： | 固氮树种 固氮效率 叶片含氮量 综合评价 |

| Abstract: | 29 kinds of plants with N fixation were chosen to test their N fixation efficiency, leaf N concentration (fresh leaf, leaf litter) and relative stem height, diameter growth. With the synthetic evaluation of these measurement parameters and the N exporting ratio of leaves, we could choose the trees which grow well and helpful to the soil. The results showed that the measurement parameters within groups were not remarkable but significant between groups; There were significant correlation (correlative coeffic... |
