图1 氮肥用量、秸秆和菌根真菌对玉米籽粒产量、氮素积累量和收获指数的影响 M0、M1、M2分别代表对照、菌丝室只有AMF菌丝、菌丝室有根和菌丝。N180S0、N180S1、N360S0、N360S1分别代表施氮量180 kg km-2条件下无秸秆、180 kg km-2条件下有秸秆、360 kg km-2条件下无秸秆、360 kg km-2条件下有秸秆处理。同一年度中, 同列数据后不同字母表示处理间P < 0.05水平差异显著性。

Fig. 1 Effects of N fertilization, straw, and mycorrhizae on maize grain yield, N accumulation, and harvest index M0 represents the control; M1 represents that only AMF hyphae can enter the hyphal chamber from the growth chamber; M2 represents that both roots and AMF can enter the hyphal chamber from the growth chamber. N180S0, N180S1, N360S0, N360S1 represent nitrogen level of 180 kg hm-2 without straw, 180 kg hm-2 and straw, 360 kg hm-2 without straw and 360 kg hm-2 with straw, respectively. In the same year, different lowercase letters within a column indicate significantly differences at P < 0.05 among the treatments.
