图1 不同品种及磷水平条件下花生3种氮源氮积累量 标以不同小写字母的柱值于处理间0.05水平上差异显著。NN: 根瘤固氮; SN: 土壤氮; FN: 肥料氮; P0: 施磷量0 kg hm-2; P45: 施磷量45 kg hm-2; P90: 施磷量90 kg hm-2; P135: 施磷量135 kg hm-2; P180: 施磷量180 kg hm-2。

Fig. 1 N accumulated amounts of three sources for peanut under different varieties and P rates Bars superscripted by different letters are significantly different at the 0.05 probability level among treatments. NN: nitrogen fixed by root nodule; SN: nitrogen from soil; FN: nitrogen from fertilizer; P0: 0 kg hm-2 of P fertilizer; P45: 45 kg hm-2 of P fertilizer; P90: 90 kg hm-2 of P fertilizer; P135: 135 kg hm-2 of P fertilizer; P180: 180 kg hm-2 of P fertilizer.
