- W2892917328 abstract "应用乙炔抑制培养法研究了水分、温度、氮源和碳源等影响因子对三峡库区腹地消落带土壤N2O排放和反硝化作用的影响，并与原位试验结果进行了比较。结果表明，土壤含水量是影响土壤N2O排放和反硝化作用的重要因素，反硝化速率随着土壤充水孔隙度（WFPS）的增加而增大，土壤反硝化速率最大值出现在土壤WFPS为100%时，N2O排放速率最大值出现在土壤WFPS为60%时。温度在10~40℃范围内，土壤N2O排放速率和反硝化速率随着温度的升高而增大，相关性分析表明，土壤N2O排放速率和反硝化速率均与温度呈显著正相关。外加氮源为NO3--N时，反硝化速率随氮源量的增加有减小的趋势，过多的硝态氮抑制反硝化作用；而添加易被微生物利用的葡萄糖作为碳源则会明显提高土壤反硝化速率，当每千克土加入碳源量为240 mg时反硝化速率最大。" @default.
