Summary

The results showed that <i>L. chinensis</i> has strong BNI-capacity. At a concentration of 1 mg mL<sup>-1</sup>, <i>L. chinensis</i>' root exudates inhibited nitrification in soils influenced by <i>Puccinellia tenuiflora</i> by 72.44%, while DCD only inhibited it by 68.29%. The nitrification potential of the soil of <i>L. chinensis</i> community was only 53% of the <i>P. tenuiflora</i> or 41% of the <i>Suaeda salsa</i> community. We also showed that the supply of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mtext>N</mml:mtext><mml:msup><mml:mrow><mml:msub><mml:mtext>H</mml:mtext><mml:mn>4</mml:mn></mml:msub></mml:mrow><mml:mo>+</mml:mo></mml:msup><mml:mo>-</mml:mo><mml:mtext>N</mml:mtext></mml:mrow></mml:math> driven by <i>L. chinensis</i>' BNI can meet its requi
