图3. 物种、氮形态、土壤深度和月份对古尔班通古特沙漠角果藜(A, B)和碱蓬(C, D)吸收速率的影响(平均值±标准差)。不同大写字母表示同一月份和土壤深度3种形态的氮对比有显著差异(p < 0.05); 不同小写字母表示同一物种和氮形态不同土壤深度间对比有显著差异(p < 0.05)。

Fig. 3. Effects of species, nitrogen (N) morphology, soil depth and month on nitrogen uptake rate of Ceratocarpus arenarius (A, B) and Suaeda glauca (C, D) in Gurbantünggüt Desert (mean ± SD). Different uppercase letters indicate significant differences (p < 0.05) among the three forms in the same month and soil depth; different lowercase letters indicate significant differences (p < 0.05) between the two soil depths for the same species and nitrogen form.
