| 摘 要： | 树木固氮是森林土壤氮素的重要来源,许多固氮树种能在瘠薄的土壤上生长,对土壤的改良起着重要作用;在混交林中作伴生树种有效地促进主林木的生长;农区常用它作有机肥源,调节氮素的供需平衡,促进农业增产。固氮树种的研究和利用逐渐引起人们的重视(Bo-nd,1976;Sprent,1979)。紫色土是四川盆地的主要土类,该区森林植被覆盖率低,水土

| Abstract: | Soil conditions had obvious influences on the root-node formation and nitrogen fixation in the saplings of several species of trees. Amorpha fruticosa, Alnus cremastogyne can get higher N2-fixing ability only on the neutral medium loam and on the calcium light loam. Coriaria sinica, Robinia pseudo acacia can get high N2-fixing ability on the neutral medium loam, but lower on the acid soil Acacia mearnsii can obtain higher N2-fixing ability on the acid soil, but low on the neutral soil, and it can not show a... |
