盖氏假单胞菌PG-9对苹果土壤细菌OTU数量的影响

盖氏假单胞菌PG-9对土壤细菌OTU数量的影响见图5。PG-9菌株处理共得到3474个OTUs，特有的为520个OTUs，CK处理共得到3354个OTUs，特有的为400个OTUs。其中，PG-9菌株处理和CK处理共有的OTUs为2954个。结果表明，施用盖氏假单胞菌PG-9菌株处理后丰富了土壤细菌群落物种数量。The effect of Pseudomonas putida PG-9 on the number of soil bacterial operational taxonomic units (OTUs) is shown in Figure 5. The PG-9 treatment obtained a total of 3474 OTUs, with 520 unique OTUs, while the control treatment (CK) obtained a total of 3354 OTUs, with 400 unique OTUs. Among them, there were 2954 OTUs shared between the PG-9 treatment and the CK treatment. These results indicate that the application of Pseudomonas putida PG-9 enriches the species diversity of soil bacterial communities.
