控制稻田甲烷排放的农业管理措施研究

AgricuItural Measures Taken in controlling the Methane Emission Flux from Rice Paddy

  • 摘要: 1990~1992年连续3a,对北京和南京具有代表性稻田进行了甲烷排放通量测定。结果表明,甲烷排放日变化规律受土壤理化性质、农业管理措施、气候变化等影响而变化,在下午15:00~18:00出现高峰值 ̄(1-6),甲烷排放季节变化规律在分蘖期和孕穗期两次出现高峰。采取不同的农业管理措施对稻田甲烷排放的影响显著:间歇灌溉对烤田后的稻田能降低甲烷排放又可增加水稻产量;南方地区垅作栽培有利于减少冬水田甲烷排放,北方地区旱种可减少甲烷排放;有机肥能促进甲烷排放,稻田分蘖期和孕穗期施用硫酸铵和尿素能抑制甲烷排放。
