图2 不同时期秸秆分解率变化(平均值±标准差)。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。不同大写字母表示不同分解环境同种秸秆分解率差异显著; 不同小写字母表示不同秸秆同一分解环境下秸秆分解率差异显著; 星号表示不同秸秆间分解率差异显著(**, p < 0.01; ***, p < 0.001)。

Fig. 2 Change of straw decomposition rate during different periods (mean ± SD). I, maize and potato intercropping; M, maize monoculture; P, potato monoculture. MS, maize straw; PS, potato straw; XS, mixed straw. Different uppercase letters in the figure indicate significant differences in decomposition rates of the same straw between different decomposition environments; different lowercase letters indicate that the decomposition rates of different straw under the same decomposition environment are significantly different; asterisks indicate significant differences in decomposition rates among different straw types (**, p < 0.01; ***, p < 0.001).
