图2. 两种气候条件下植物根际土壤主要养分含量和pH值的比较(平均值±标准偏差, n = 3)。**和ns分别代表半干旱和半湿润环境下显著性水平小于0.01和不显著。SA, 半干旱; SH, 半湿润。
Fig. 2. Comparisons of major nutrients and pH value in rhizospheric soils between two different climatic conditions (mean ± SD, n = 3). ** and ns indicate that the differences between semi-arid and sub-humid conditions are significant at the 0.01 level, and not significant, respectively. SA, semi-arid; SH, sub-humid.
