图1. 不同施氮水平下土壤N2O排放动态
箭头表示追肥;A、B分别为基肥阶段N2O排放情况和基肥第1天的排放通量;a、b、c、d分别为番茄开花期、果实膨大期、采收盛期和采收末期追肥后土壤N2O排放趋势
Fig. 1. Dynamic of N2O emission under different N application rates
The arrow indicates topdressing fertilizer; A and B represent the base fertilizer stage N2O emission and the emission flux on the 1th day; a, b, c, d indicate changes in N2O emission flux after topdressing fertilizer in flowering stage, fruit expansion stage, harvest stage and final harvest stage
