图4 不同秸秆(A、B)和不同分解环境(C、D)下单一碳源利用率(平均值±标准差)。不同小写字母表示不同处理下同种碳源含量差异显著(p < 0.05)。AWCD, 孔平均颜色变化率。AA, 氨基酸; AM, 胺类; CA, 羧酸; CH, 碳水化合物; PA, 酚类化合物; PM, 多聚物。I, 玉米马铃薯间作; M, 玉米单作; P, 马铃薯单作. MS, 玉米秸秆; PS, 马铃薯秸秆; XS, 混合秸秆。

Fig. 4 Utilization ratio of single carbon group for different straw types (A, B) and under different decomposition environment (C, D) (mean ± SD). Different lowercase letters indicate that the content of the same carbon source varies significantly among different treatments (p < 0.05). AWCD, average well color development. AA, amino acid; AM, amine; CA, carboxylic acid; CH, carbohydrate; PA, phenolic compound; PM, polymer. I, intercropping of maize and potato; M, maize monocropping; P, potato monocropping. MS, maize straw; PS, potato straw; XS, mixed straw.
