| 摘 要： | 采用田间试验方法研究了西北干旱半干旱地区覆膜和种植措施对农田土壤中N2O排放通量变化的影响。结果表明,在冬小麦生长期内,覆膜与不覆膜措施相比较,无论种植小麦与否,土壤中N2O的排放通量显著增加;种植小麦与休闲地相比较,无论覆膜与否,土壤中N2O的排放通量也显著增加。

| Abstract: | Observation on soil N2O discharge flux in winter wheat field using a closed chamber technique showed that mulching and planting had a significant influence on soil N2O discharge flux from winter wheat-soil system in northwester arid and semi-arid areas in China. The N2O discharge flux from the mulching plots of either planting or not was greater than that from no mulching plots, while the N2O discharge flux from the planting plots of mulching or not was greater than that from the fallow plots. |
