摘要
土壤理化特性是影响农田氧化亚氮 (N2 O)产生和排放的重要因素。作者主要讨论了土壤微生物、土壤质地、土壤中化学物质、土壤温度和土壤 pH值等对农田N2 O的影响。继续深入研究这些因素对农田N2 O排放的综合影响和机理以及与其排放量之间的数量关系应是未来的研究重点。为准确估计区域乃至全球范围的农田N2 O排放总量 ,对农田N2 O排放模型中关键土壤参数的确定尤为重要。
A brief account on influence of soil properties on N 2O emissions from farmland was given.Key soil factors influencing the production and emission of N 2O are soil texture, soil trace elements, soil temperature and so on.To accurately estimate N 2O emissions from farmland and hence to reduce the emissions, further study should focus on the quantitative description of N 2O emissions associated with these key factors.
