摘    要:通过在黑土玉米地与水稻田施用长效氮肥后发现 ,长效碳酸氢铵 (长碳 )与长效尿素(长尿 )能显著减少黑土玉米地N2 O的排放。与施用普通尿素相比 ,其排放量分别减少了5 9 2 %和 73 3%。长碳和长尿还能促进黑土玉米地对CH4的吸收作用。黑土水稻田施用长尿后 ,N2 O的排放减少了 6 1%。而CH4的排放却略有增加

关 键 词:长效氮肥  CH4排放  N2O排放、黑土

Abstract:Field experiments were conducted to investigate the influence of slow-releasing ammonium bicarbonate and slow-releasing urea on N 2O and CH 4 emission in maize and rice fields.The results showed that the application of slow-releasing ammonium bicarbonate and slow-releasing urea could significantly reduce N 2O emission in maize field by 59 2% and by 73 3% in rice field,respectively,compared with that of urea.These two N fertilizers could also enhance the uptake of CH 4 in maize fields.N 2O emission in rice fields was depressed by 61% in the treatment of slow-releasing urea,whereas CH 4 emission had a slightly enhancement.
Keywords:slow-releasing nitrogen fertilizers  CH  4 emission  N  2O emission  black earth soil
