Abstract

Abstract: In order to explore the effects of biocontrol bacteria BZJN1 and chemical agent benzoyl procyclonazole on soil fungal community structure, based on the fungal ITS high-throughput sequencing technology, the fungal community diversity in rhizosphere soil of Atractylodes macrocephala in chemical agent benzoyl procyclonazole treatment group, biocontrol bacteria BZJN1 treatment group, and the control group was analyzed and compared. Redundancy analysis （RDA） was used to investigate the relationship between soil environmental factors and fungal diversity. The results showed that there was no significant difference in the composition of fungi in rhizosphere soil of Atractylodes macrocephala between the chemical benzoyl·propionazole treatment group, the biocontrol bacteria BZJN1 treatment group and the control group. The dominant bacterial groups were Ascomycota 76.34%, Basidiomycota 12.49% and Zygomycota 3.11%. The relative abundance of fungi in rhizosphere soil of Atractylodes macrocephala was significantly changed in the treatment group of benzoyl · propiconazole and the treatment group of biocontrol bacteria BZJN1. RDA analysis showed that different environmental factors were related to the fungal community to some extent, and the abundance of the fungal communities of the three genera in the rhizosphere soil of Atractylodes macrocephala was positively correlated with pH, catalase and available potassium.

Key words: Atractylodes macrocephala, biocontrol bacteria BZJN1, benzoyl · procyclonazole, fungus community, high-throughput sequencing
