Analysis of Soil Fungal Community in Aged Apple Orchards in Luochuan County, Shaanxi Province

The Luochuan area is an important for apple production in China. With the renewal and transformation of aged orchards, occurrence replant disease (ARD) was inevitable has seriously affected sustainable development apples. Therefore, we randomly selected 14 soil samples from orchards to study structural changes fungal community. results showed that there were significant differences diversity communities between different orchards. harmful fungi Gibberella, Fusarium, Cryptococcus existed area, but their abundances A FUN Guild analysis mainly present saprotroph pathotroph nutrition modes. Pathogenic widely present, which increased risk growth fruit trees. To sum up, a strong correlation ages unbalanced microbial community structure. pathogenic could be prevented controlled during reduce impact ARD on industry.
