图1. 亚热带人工林内乔灌草根际土壤净氮矿化速率(A)、净铵化速率(B)和净硝化速率(C)。
AM, 杨桐; CL, 杉木; DA, 暗鳞鳞毛蕨; EM, 格药柃; LC, 檵木; PE, 湿地松; PM, 马尾松; WJ, 狗脊蕨。不同小写字母代表同一人工林内相同取样季节下不同物种之间差异显著(p < 0.05), 未标注小写字母则表示差异不显著。不同大写字母代表相同取样季节不同人工林类型间差异显著(括号内为4月, 括号外为7月; p < 0.05)。*代表同一人工林内相同物种不同取样季节差异显著(p < 0.05)。

Fig. 1. Net mineralization rate (Nmin), net ammonification rate (Namm), and net nitrification rate (Nnit) of the rhizosphere soil of overstory trees, understory shrubs, and herbs in subtropical plantations.
AM, Adinandra millettii; CL, Cunninghamia lanceolata; DA, Dryopteris atrata; EM, Eurya muricate; LC, Loropetalum chinense; PE, Pinus elliottii; PM, Pinus massoniana; WJ, Woodwardia japonica. Different lowercase letters denote significant difference among species of each plantation in the same season (p < 0.05), while unmarked lowercase letters denote inapparent difference. Different uppercase letters denote significant difference among plantations in the same season (April is in the bracket, July is outside the bracket; p < 0.05). *denotes significant difference between the different seasons for the same species in each plantation (p < 0.05).
