图1 施石灰和秸秆还田对双季早稻产量及其构成、氮素吸收的影响(2015-2018) CK、L、RS和L+RS分别表示对照、单施石灰、秸秆还田、秸秆还田配施石灰。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. 1 Effects of liming and straw incorporation on grain yield and its components, and N uptake in early rice (2015-2018) CK, L, RS, and L+RS mean control, liming, straw incorporation, and straw incorporation with liming, respectively. 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.
