Microbiome Revel the Effects of Biogas Fertilizer on Soil Microbial Community Structure and Diversity in Perennial Apple Orchards

Fruit trees are perennial crops that grow in one place for whole life, all of this leads to deteriorate of soil and decline of fruit quality and yield. Microbial diversity and structure are important soil factors affecting stress-resistance and quality of fruit trees. Biogas fertilizer plays an important role in improving resistance and quality. Whether and how it can improve the microbial structure of orchard need to be discovered. In order to study the effects of biogas fertilizer on orchard soil microbial diversity and community structure in rainfed loess plateau of China, 7-year-old Fuji apple orchard was used as material, and biogas fertilizer was applied continuously for three years. Results showed that fruit quality and soil microbial community structure were significantly improved after applying biogas fertilizer.
