为掌握玉米田的N2O释放规律,采用定位试验的方法,探讨增施有机肥和作物秸秆对农田N2O排放通量的影响。试验结果表明:N2O通量有明显的季节变化,夏季高于春秋两季;空地的N2O排放通量平缓;玉米的生长活动有利于N2O的生成及排放:施肥能促进土壤N20排放通量的增加。

The N2O flux changed obviously with the change of season. The N2O release in field can be accelerated by planting com, applying nitrogen fertilizer. Applying corn straw and pig manure can also enhance N2O release flux as the abundant carbon, nitrogen con- tent in it. Under the same carbon content, the N2O release flux is higher than that in corn straw; under different carbon content, the N2O release flUX is increased with the increase of corn straw and pig manure concentration.
