1) nitrogen-fixing plants
固氮类植物
1.
Many researches had showed that the functions of nitrogen-fixing plants are diversity and complex,and they strongly dominate many ecosystem processes.
固氮类植物是陆地生态系统中的一个重要功能群,它们广泛存在于陆地生态系统中,是陆地生态系统最重要的氮源,大量研究表明,固氮类植物在陆地生态系统中的生态功能表现出明显的复杂性和多样性,对于生态过程有很强的主导性和控制性。
3) slope croplands
固氮植物篱
1.
Field experiments were conducted to test the effects of contour hedgerow system on slope croplands in Ningnan County, which lies in the dry and hot valley of Jinsha River in the southwestern Sichuan with more than 90 % of its rainfall in monsoon.
固氮植物篱近年来被热带地区用作防治坡耕地的水土流失和肥力退化的有效手段。
4) nitrogen fixing plants
固氮植物 NFP
6) leguminous N 2 fixing plant
豆科固氮植物
1.
Because of isotopic fractionation in plant fixed N 2 transport from nodules to shoots and leaves,δ 15 N values of vrious parts of leguminous N 2 fixing plant are different.
由于生物固定的氮在植物体内迁移过程中存在着同位素分馏效应，导致豆科固氮植物不同部位的δ１５Ｎ值彼此各不相同，我们的结果证实，茎叶的１５Ｎ自然丰度普遍低于根，特别是低于根瘤。
