N1-N4, 氮浓度分别为3、5、15、30 mmol·L-1; P1-P4, 磷浓度分别为0.25、0.5、1、2 mmol·L-1。不同小写字母表示不同氮处理或不同磷处理下差异显著(p < 0.05)。
Fig. 3. Effects of different nitrogen and phosphorus concentrations on the root:shoot biomass ratio and the leaf:stem biomass ratio of Dodonaea viscosa seedlings (mean ± SE).
N1-N4, the nitrogen concentrations were 3, 5, 15 and 30 mmol·L-1, respectively; P1-P4, the phosphorus concentrations were 0.25, 0.5, 1 and 2 mmol·L-1, respectively. Different lowercase letters indicate significant differences (p < 0.05) among different nitrogen treatments or different phosphorus treatments.
