摘要
旱地农田是大气中CO2和N2O的重要排放来源,农业生产活动对全球气候变化有着重要影响。本文综述了旱地农田土壤N2O和CO2排放机理、影响因素,并从合理施肥、合理灌溉和优化农作措施等方面提出减排措施,以期实现农业可持续发展。
Dryland farmland is an important emission source of CO2 and N2O in the atmosphere,and agricultural production activities have an important impact on global climate change.The mechanism and influencing factors of N2O and CO2 emission from dryland farmland were reviewed in this paper,and emission reduction measures were proposed from the aspects of rational fertilization,rational irrigation and optimized farming measures,with a view to achieving sustainable agricultural development.
