图3 不同行距配置下大豆地上和地下生物量变化同一生育时期中, 不同小写字母表示处理间差异在0.05水平显著。V3、V5和R2分别代表大豆的第一节龄期、第二节龄期及盛花期。缩写同图2 。
Fig. 3 Aboveground and belowground biomass of soybean at different row spacing patterns in 2012 and 2013 Bars represented by a different small letters within each group in the same growth stage are significantly different at the 0.05 probability level. V3, V5, and R2 stand for the third trifoliolate, the fifth trifoliolate and full bloom, respectively. Abbreviations are the same as those given in Figure 2 .
