图4. 未增温和增温时不同栽种处理根区土壤革兰氏阳性菌/革兰氏阴性菌(GP/GN)和真菌/细菌(F/B)(平均值±标准误差)。U, 未增温; W, 增温。C, 裸地; Y, 云杉单种; L, 冷杉单种; H, 混种。Fp, 树种效应; Fw, 增温效应; Fp × w, 树种和增温的交互效应; **, p < 0.01; ***, p < 0.001; ns, p > 0.05。不同小写字母表示未增温和增温时不同栽种处理根区GP/GN和F/B有显著差异(p < 0.05)。柱下*表示t检验有显著差异(p < 0.05)。 |
Fig. 4. The GP/GN and F/B ratios (mean ± SE) in root zone soil of different planting treatments with and without warming. GN, gram-negative bacteria; GP, gram-positive bacteria. F, fungi; B, bacteria. U, unwarming; W, warming. C, unplanted area; Y, Picea asperata; L, Abies faxoniana; H, mixed. Fp, plant types effect; Fw, warming effect; Fp × w, plant types × warming interaction effect; **, p < 0.01; ***, p < 0.001; ns, p > 0.05. Different lowercase letters indicate significant differences in the GP/GN and F/B in root zone of different planting treatments under unwarming and warming (p < 0.05). * under the column indicates a significant difference in the t-test (p < 0.05). |
