There were significant differences in fungal community composition between continuous and non-continuous cropping groups of sugar beet rhizosphere.
Compared with non-continuous cropping, continuous cropping increased the relative abundance of potentially pathogenic fungi such as Tausonia, Gilbellulopsis, and Fusarium, but decreased the relative abundance of Olpidium.
