In order to explore the effects of different soil and water conservation tillage techniques on nitrogen utilization and greenhouse gas emissions in sloping farmland of black soil in Northeast China, a field experiment was conducted. Seven tillage treatments were set up: transverse slope planting ( TP ), ridge to the district field ( RF ), subsoiling tillage ( SF ), transverse slope planting + subsoiling tillage (TP-S), ridge to the district field + subsoiling tillage (RF-S), transverse slope planting + ridge to the district field (TP-R), and down-slope cultivation (CK). Explore the effects of soil and water conservation tillage techniques on soil nutrient status, greenhouse gas emission, nitrogen absorption and utilization, and yield of black soil slope farmland in Northeast China. The results showed that during the whole growth period of maize, soil and water conservation tillage treatment significantly increased maize yield, organ nitrogen transport rate and nitrogen use efficiency, and some soil and water conservation tillage measures could also significantly reduce N2O and CO2 emissions. Among them, at the maturity stage of maize, the plant yield of soil and water conservation tillage measures were increased by 3.39%~26.43% compared with that of CK treatment, and TP-S treatment had the highest improvement effect. For nitrogen use efficiency, soil and water conservation tillage technology were increased by 25.23% (RF treatment ) ~ 76.98% (TP-S treatment) compared with CK treatment, and the improvement effect was significant. For CO2 emissions, except for SF treatment, the remaining soil and water conservation tillage treatments were significantly lower than that of CK treatment. However, for N2O emissions, TP treatment, TP-S treatment and TP-R treatment were significantly lower than that of CK, while SF treatment, RF treatment and RF-S treatment were significantly higher than that of CK treatment. Therefore, it was suggested that the local maize planting should adopt the soil and water conservation tillage technology of transverse slope planting+subsoiling tillage.
