图5 施石灰和秸秆还田对土壤有机质(a)和全氮(b)含量的影响(2018年) 缩写同图1。误差线表示平均值的标准差(n = 3)。同一年份标的不同小写字母的柱值在不同处理间差异显著(P < 0.05)。

Fig. 5 Effects of liming and straw incorporation on soil organic matter (a) and total N content (b) (2018) Abbreviations are the same as those given in Fig.1. Error bars represent the standard deviation of the mean (n = 3). Bars superscripted by different letters are significantly different at P < 0.05 in the same year.
