图4 不同施氮处理对糜子各生育时期干物质积累与根冠比的影响(2019-2020) 图中数据为3次重复的平均值±标准误。柱上不同小写字母表示同一生育时期不同施氮处理间差异显著(P < 0.05)。*和**分别表示在0.05和0.01水平上差异显著, ns表示差异不显著。处理和缩写同图2。

Fig. 4 Effect of different N treatments on dry matter accumulation and root-shoot ratio at different growth stages of proso millet in 2019 and 2020 The values were means ± standard errors of three repetitions. Different lowercase letters above the bars indicate significant difference among different N treatments at the same growth stage at P < 0.05. * and ** denote significant difference at the 0.05 and 0.01 probability levels respectively, ns denotes no significant difference. Treatments and abbreviations are the same as those given in Fig. 2.
