Pseudomonas putida PG-9 对苹果土壤真菌 Alpha 多样性的影响

盖氏假单胞菌 PG-9 对苹果土壤真菌 Alpha 多样性的影响见表 8。施用盖氏假单胞菌 PG-9 后，其 ACE、Chao1、Shannon、Simpson 指数分别为 458.03±39.79、450.85±36.32、3.33±0.11、0.07±0.01。其中 ACE、Chao1 指数分别比对照降低 1.76% 和 1.95%，说明 PG-9 菌株处理丰富度低于对照。Shannon 指数比对照提高 6.05%，说明 PG-9 菌株处理多样性高于对照。其均与对照间差异不显著 (P>0.05)。结果说明，施用盖氏假单胞菌 PG-9 在 1 年内对土壤真菌 Alpha 无明显影响。The impact of Pseudomonas putida PG-9 on the alpha diversity of apple soil fungi is shown in Table 8. After the application of Pseudomonas putida PG-9, the ACE, Chao1, Shannon, and Simpson indices were 458.03±39.79, 450.85±36.32, 3.33±0.11, and 0.07±0.01, respectively. Among them, the ACE and Chao1 indices were reduced by 1.76% and 1.95% compared to the control, indicating that the abundance of the PG-9 strain treatment was lower than the control. The Shannon index was increased by 6.05% compared to the control, indicating that the diversity of the PG-9 strain treatment was higher than the control. However, the differences between them and the control were not significant (P>0.05). The results indicate that the application of Pseudomonas putida PG-9 had no significant impact on the alpha diversity of soil fungi within one year.
