摘  要:沼肥富含养分且产生量大,被还田利用,但施用不当可导致土壤硝态氮淋失。为提高沼肥还田施用效果提供参考,从不同进料沼肥的特点、土壤硝态氮淋失影响因素、土壤硝态氮生化还原影响因素及沼肥硝态氮淋失的防控措施等方面综述其研究现状,并对沼肥还田硝态氮淋溶的防控研究进行展望。Biogas manure with abundant nutrients is widely applied to fields but improper application can bring about soil nitrate nitrogen leaching. The current research progress on soil nitrate nitrogen leaching under application of biogas manure is reviewed from aspects of the characteristics of different biogas manure produced from different straw and livestock manure, factors influencing soil nitrate nitrogen leaching and biochemical reduction and the prevention and control measures of biogas manure nitrate nitrogen leaching, and the prevention and control research on nitrate nitrogen leaching under application of biogas manure is prospected to improve the effect of biogas manure application in soil.
