图3. 不同分解时期马尾松针叶形态。图A-D分别代表N+S处理下第2、4、8、12个月时针叶的外部形态，图E-H分别代表N+S处理下第2、4、8、12个月时针叶的解剖结构；图A1-D1分别代表N+SS处理下第2、4、8、12个月时针叶的外部形态，图E1-H1分别代表N+SS处理下第2、4、8、12个月时针叶的解剖结构；图A2-D2分别代表SN+S处理下第2、4、8、12个月时针叶的外部形态，图E2-H2代表SN+S处理下第2、4、8、12个月时针叶的解剖结构。N+S、N+SS、SN+S分别表示叶际微生物+土壤微生物、叶际微生物和土壤微生物3种处理。比例尺= 50 μm。

Fig. 3. Morphological changes of Pinus massoniana needles at different decomposition stages. A-D show the surface morphologies of needles in N+S treatment after 2, 4, 8 and 12 months, respectively. E-H show the anatomical structures of needles in N+S treatment after 2, 4, 8 and 12 months, respectively; A1-D1 show the surface morphologies of needles in N+SS treatment after 2, 4, 8 and 12 months, respectively. E1-H1 show the anatomical structures of needles in N+SS treatment after 2, 4, 8 and 12 months, respectively; A2-D2 show the surface morphologies of needles in SN+S treatment after 2, 4, 8 and 12 months, respectively. E2-H2 show the anatomical structures of needles in SN+S treatment after 2, 4, 8 and 12 months, respectively.N+S、N+SS、SN+S represent the phyllospheric microbes + soil microbes treatment, the phyllospheric microbes treatment and the soil microorganism treatment, respectively. Scale bars = 50 μm.
