图3. 不同处理下土壤铵态氮含量的季节动态(平均值±标准偏差)。P0W0、P0W1、P1W0、P1W1分别指不同处理方式: 去除植物+不增温、去除植物+增温、不去除植物+不增温、不去除植物+增温。不同小写字母表示同一采样时期不同处理之间差异显著(p < 0.05)。
Fig. 3. Seasonal dynamics of the soil ammonium contents under different treatments (mean ± SD). P0W0, P0W1, P1W0, P1W1 are refer to the different treatments, indicated removal- plant + controlled temperature, removal-plant + increased temperature, unremoval-plant + controlled temperature, unremoval- plant + increased temperature, respectively. Differences lowercase letters indicated significant differences between different treatments at the same sampling dates (p < 0.05).
