| 摘 要： | 用静态箱法对冬小麦不同基肥施用方式(表施、深施)和不同施用量下的土壤NO排放通量进行了研究,结果表明:肥料在土壤中的位置对NO排放通量的影响非常显著。表施处理明显促进NO的排放,表施处理平均比深施处理NO排放量高2.2倍。高肥处理总的NO排放量也明显高于低肥处理。由此可知肥料深施和减少用量都能显著降低NO排放量。

| Abstract: | Effect of different basal-dressing application methods and different amounts of fertilizer on NO emission from the soil grown with winter wheat was studied with the technique of static chamber.The results indicated that fertilizer placement considerably influenced NO emission.Surface fertilizer application favored NO emission.The NO emission flux under surface fertilizer application was 2.2 times of underground fertilizer application.The high fertilizer treatment was also favorer NO emission than the low one.We can know that fertilizer incorporation and low fertilizer can decrease NO emission flux in winter wheat field. |
