Nitrogen fertilizer application，utilization of green manure，and addition of biochar could influence soil nitrous oxide(N2O)emission，this study investigated the impact of the application of their combination on dry land soil N2O emission，providing theoretical support for exploring effective practice to control soil N2O emission.An incubation experiment was conducted，including conventional chemical nitrogen fertilizer(N100)，incorporation of green manure together with 30% chemical N reduced...
