摘    要:草地生物固氮不仅是草地生态系统氮素循环输入过程的重要部分,而且与集约化草地畜牧业的建立和退化草场的恢复有重要的关系。在草地生态系统生物固氮的3种方式中,豆科植物根瘤生固是重要方式,细菌自主固氮值得重视,而联合固氮在草地生物固氮中有着广泛的应用前景与潜力。

关 键 词:生物固氮 集约化草地 畜牧业 氮素循环

Abstract:Grassland bio-nitrogen fixation not only is a important part of grassland ecological systemnitrogen cycle, but also has a important relation with intensive grassland animal hsubandry construction and regressive grassland rocovery. Rhizobia nitrogen fixation in common of leguminous plants is a important mode, bacteria nitrogen fixation by themselves should be pay more attention, and nitrogen fixation in combination owns extensive application preview and potential ability in grassland bio-nitrogen fixation.
Keywords:Bio-nitrogen fixation   intensive grassland animal husbandry   nitrogen fixation
