Abstract:

采用遮光密闭箱和气相色谱法,研究了化肥、化肥+稻草、50%沼液+50%化肥、100%沼液4个处理下麦季CH4和N2O的排放特征,并运用全球增温潜势(GWP)对麦季CH4和N2O排放的温室效应进行了估算。研究结果表明,与化肥处理相比,化肥+稻草处理显著(P<0.05)提高了麦季CH4和N2O排放通量,使其所产生的GWP及单位产量的GWP显著(P<0.05)增加,分别提高了57.90%和52.00%;而100%沼液、50%沼液替代化肥处理减少了麦季GWP及单位产量的GWP,分别降低了25.39%、10.88%和24.16%、10.97%,主要是由于沼液处理降低了麦季N2O排放总量。可见,稻麦轮作条件下沼液替代化肥措施会降低稻茬麦季的综合温室效应。
