通过田间试验研究了华北平原玉米-小麦轮作条件下连续施用有机无机氮肥对N_2O和NO排放的影响。试验共设8个处理：不施肥（对照）、无机氮（无机氮）处理。（Nmin），每季施氮200 kg·hm ~ 2，50%无机肥氮+50%牛粪氮。(50 75%无机肥+25%牛粪氮（25%CM）、25%鸡粪氮（25%FC）或25%猪粪氮（50%FP）。(25% FP）。Nmin处理下N2 O和NO的年排放量分别为2.71和0.39 kg Nha ~ 2，N2 O和NO的排放因子分别为0.50%和0.07%，与Nmin处理相比，50%的无机氮被有机肥替代后，N2 O的排放量并没有降低50%FC和50%FP条件下，NO的年排放量分别减少了49.0%和27.8%。相比之下，当25%的矿质氮被粪肥氮替代时，与Nmin处理相比，年N2 O排放量减少了0.21 -38%。(25% CM、25%FC和25%FP）。大部分减少发生在玉米季节。25%CM、25%FC和25%FP处理与Nmin处理相比，对NO排放没有影响。在相同的施用量下，不同有机肥的N_2O和NO排放量无明显差异，这可能与它们的C/N相似有关。除麦季50%FC处理外，有机肥氮替代部分无机肥氮对作物产量影响不显著。结果表明，25%有机肥N +75%无机肥N的配施方式在不影响作物产量的前提下，最有可能减少该地区玉米-小麦轮作体系中N2 O的排放。
A field experiment was conducted to evaluate the influence of the continuous application.of organic and mineral N fertilizer on N2O and NO emissions under maize and wheat rotation on the.North China Plain. This study included eight treatments: no fertilizer (control); mineral N fertilizer.(Nmin) at a rate of 200 kg N ha1 per season; 50% mineral fertilizer N plus 50% cattle manure N.(50% CM), 50% chicken manure N (50% FC) or 50% pig manure N (50% FP); 75% mineral fertilizer.N plus 25% cattle manure N (25% CM), 25% chicken manure N (25% FC) or 25% pig manure N.(25% FP). The annual N2O and NO emissions were 2.71 and 0.39 kg N ha1, respectively, under the.Nmin treatment, with an emission factor of 0.50% for N2O and 0.07% for NO. Compared with the.Nmin treatment, N2O emissions did not dier when 50% of the mineral N was replaced with manure.N (50% CM, 50% FC and 50% FP), while annual NO emissions were significantly reduced by 49.0%.and 27.8% under 50% FC and 50% FP, respectively. In contrast, annual N2O emissions decreased by.21–38% compared to the Nmin treatment when 25% of the mineral N was replaced with manure N.(25% CM, 25% FC and 25% FP). Most of the reduction occurred during the maize season. The 25%.CM, 25% FC and 25% FP treatments had no eect on NO emissions compared to the Nmin treatment..There was no obvious dierence in annual N2O and NO emissions among the organic manures at the.same application rate, probably due to their similar C/N ratio. Replacing a portion of the mineral.fertilizer N with organic fertilizer N did not significantly aect crop grain yield, except for the 50%.FC treatment in the wheat season. Overall, the results suggest that the combined application of 25%.organic manure N plus 75% mineral fertilizer N had the most potential to mitigate N2O emissions.while not aecting crop yield in the maize and wheat rotation system in this area of China.
