摘要:
采用室内28 ℃恒温培养法，研究添加水合氧化铁与黄腐酸对不同pH值及不同含水量土壤硝化作用的影响。结果表明，与不添加水合氧化铁、黄腐酸(CK)相比，仅加入水合氧化铁、同时加入水合氧化铁与黄腐酸可显著促进pH值为 5.1紫色潮土硝化作用的发生(P<0.05)，而显著抑制pH值为7.8紫色潮土的硝化作用(P<0.05)，仅添加水合氧化铁对pH 值为4.5的黄壤土硝化作用影响不显著(P>0.05)，加入黄腐酸可以显著抑制pH值为 5.1、7.8的紫色潮土的硝化作用(P<0.05)；土壤含水量分别为最大持水量(WHC)的50%、100%、200%条件下，与CK相比，加入水合氧化铁可以显著促进净硝化速率的增加，而仅加入黄腐酸多显著抑制硝化过程的发生(P<0.05)； pH值为5.1的紫色潮土在添加底物硫酸铵、含水量为100% WHC条件下，加入黄腐酸可以显著刺激N2O的排放，而加入水合氧化铁则显著抑制N2O的排放(P<0.05)。
