图3. 大秃顶子山不同海拔胞外酶碳(C)、氮(N)、磷(P)活性及其化学计量比(平均值+标准误差, n = 3)。不同大写字母表示不同海拔间差异显著(p < 0.05)。AP, 酸性磷酸酶; BG, β-1, 4-葡萄糖苷酶; NAG, 几丁质酶。
Fig. 3. Exoenzyme carbon (C), nitrogen (N), and phosphorus (P) activities and their stoichiometric ratios under different altitudes in Mt. Datudingzi (mean + SE, n = 3). Different uppercase letters represent significant differences at 0.05 level among different altitudes. AP, acid phosphomonoesterase; BG, β-1,4-glucosidase; NAG, N-acetyl-β- glucosaminidase.
