nitrogen fixation

/ˈnaɪtrədʒən fɪkˈseɪʃən/

翻译: 指将空气中的分子态氮转化为氨或含氮化合物的过程。通常由固氮细菌等微生物完成,也可通过工业方法实现,从而使氮能被植物利用。

  • zh指将空气中的分子态氮转化为氨或含氮化合物的过程。通常由固氮细菌等微生物完成,也可通过工业方法实现,从而使氮能被植物利用。

The chemical process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds, typically by certain bacteria or through industrial methods, making nitrogen available for plant growth.

  1. Biological processC1formal

    The process by which certain bacteria and other microorganisms convert atmospheric nitrogen gas into ammonia, a form that plants can use.

    zh固氮作用

    • Rhizobium bacteria in root nodules perform nitrogen fixation for legumes.
    • Nitrogen fixation is essential for the natural nitrogen cycle.
    • Farmers often use crops that promote nitrogen fixation to enrich the soil.
  2. Industrial processC1formal

    The industrial conversion of atmospheric nitrogen into nitrogen compounds, such as ammonia, typically via the Haber-Bosch process.

    zh工业固氮

    • The Haber-Bosch process is the primary method of industrial nitrogen fixation.
    • Industrial nitrogen fixation produces fertilizers that support global agriculture.
    • Without industrial nitrogen fixation, food production would be severely limited.
