Abstract:
Taking the soil of dryland apricot orchards in Pengyang County，Ningxia as the test material，and using high-throughput sequencing technology，the effects of different covering materials (sawdust，wheat straw，white film and black film) on the structural characteristics of soil bacterial communities were studied，in order to provide a reference for soil management and ecological sustainable practice in apricot orchards in arid areas.The results showed that compared to the control，all four mulching treatments significantly reduced the α-diversity indices (Chao1 and Shannon) of the soil bacterial community and markedly altered its composition.At the phylum level，Proteobacteria,Actinobacteria，and Acidobacteria were the dominant bacterial groups.Plastic film mulching significantly increased the relative abundance of Actinobacteria and Chloroflexi，while organic mulching (sawdust and wheat straw) favored the enrichment of Proteobacteria.Redundancy analysis indicated that soil moisture，temperature，and maximum water-holding capacity were the primary environmental factors driving changes in the bacterial community，while soil chemical properties such as electrical conductivity，total potassium，and available potassium also had significant effects.In conclusion，different mulching materials reshape the soil bacterial community composition by regulating soil hydrothermal conditions and nutrient availability but generally suppress microbial diversity.
