英文摘要A better understanding of nitric oxide (NO) emission from a typical rice-wheat agroecosystem in eastern China is important for calculating the regional inventory and to propose effective NO mitigation options. Nitric oxide flux measurements by static chamber method were made from treatments of conventional nitrogen-fertilizer (NPK plus urea) application, no-nitrogen application, and nitrogen-fertilizer with incorporation of wheat straw residue for an entire rotation period (June 2002 to June 2003). During the wheat growing season two further treatments of fertilizer without crops planted and bare soil without nitrogen (N) fertilization were applied. Total annual NO emissions for the conventional fertilizer, no N fertilizer and fertilizer plus straw application were 0.44 +/- 0.01, 0.22 +/- 0.01, and 0.57 +/- 0.02 kg N ha(-1)y(-1), respectively. On average 27% of this emission occurred during the rice season due to flooding/drainage cycle. The N fertilizer-induced emission factor for the conventional fertilizer treatment was 0.05% of the total N applied. Incorporation of wheat straw in the rice season showed no significant effect on NO flux due to the high C/N ratio of the straw incorporated. During the wheat growing season, NO emissions for all treatments had similar variation pattern controlled by soil moisture dynamics. Total NO emissions in the wheat season for fertilized bare soil (no wheat planted) were 0.389 +/- 0.01 and 0.21 +/- 0.01 kg N ha(-1) y(-1), respectively. The results indicate the importance of N fertilizer and soil moisture to nitrogen loss through the formation of NO.
