生物硝化抑制作用（BNI）可以降低土壤净硝化速率和氧化亚氮（N2O）排放。为了确定对总氮(N)转化过程和N2O排放的影响，采用15N示踪法对种植高bni腕足草和原生非bni草的土壤样品进行了培养实验。腕鱼属植物通过增加顽固性有机氮的总矿化量和土壤吸附NH4+的净释放量来增加土壤铵态氮（NH4+）的供应，同时降低NH4+的固定速率。与毛藻相比，Brachiaria减少了37.5%的土壤总硝化，通过自养硝化减少了14.7%的N2O产量。相比之下，在16 d的培养过程中，Brachiaria培养显著增加了土壤N2O排放量，从Eremochloa培养下的90.42 μg N2O- n kg - 1增加到144.31 μg N2O- n kg - 1 (p
Biological nitrification inhibition (BNI) in the tropical grass Brachiaria humidicola could reduce net nitrification rates and nitrous oxide (N2O) emissions in soil. To determine the effect on gross nitrogen (N) transformation processes and N2O emissions, an incubation experiment was carried out using 15N tracing of soil samples collected following 2 years of cultivation with high-BNI Brachiaria and native non-BNI grass Eremochloaophiuroide. Brachiaria enhanced the soil ammonium (NH4+) supply by increasing gross mineralization of recalcitrant organic N and the net release of soil-adsorbed NH4+, while reducing the NH4+ immobilization rate. Compared with Eremochloa, Brachiaria decreased soil gross nitrification by 37.5% and N2O production via autotrophic nitrification by 14.7%. In contrast, Brachiaria cultivation significantly increased soil N2O emissions from 90.42 μg N2O-N kg−1 under Eremochloa cultivation to 144.31 μg N2O-N kg−1 during the 16-day incubation (p
