图2 种植密度和生态区对不同大豆品种地上生物量的影响 不同大写字母表示不同生态区之间差异显著（P < 0.05），不同小写字母表示同一生态区下不同密度之间差异显著（P < 0.05）。“*”、“**”和“***”分别表示在P < 0.05、P < 0.01和P < 0.001水平存在显著差异，“ns”表示差异不显著（P > 0.05）。C：品种，D：种植密度，E：生态区。下同。

Fig.2 Effects of planting density and ecological region on the aboveground biomass for different soybean varieties Different uppercase letters indicate significant differences among different ecological regions at P < 0.05 level, different lowercase letters indicate significant differences among the different planting densities under the same ecological region at P < 0.05 level. “*”,“**”and“***”indicate significant differences at P < 0.05, P < 0.01 and P < 0.001 levels, respectively,“ns”indicates no significance (P > 0.05). C: cultivar, D: planting density, E: ecological region. The same below.
