Effect of Sheep Plate Manure and Granular Organic Fertilizer on Soil Physicochemical Properties and Fungal Community Diversity in Alpine Mining Areas
In order to enhance soil fertility in the artificially planted grassland of Muli Mining area and promote the sustainability of ecological restoration,Muli Mining area was selected as the experimental site.A total of 16 treatments were applied,consisting of sheep board manure+granular organic fertilizer,while no fertilization was used as the control group.Soil chemical analysis method was employed to determine the phys-ical and chemical properties of soil.High-throughput sequencing was conducted to assess soil fungal commu-nity diversity.The results revealed that treatment combination MF16 yielded the most favorable outcomes,with soil contents of total nitrogen(8.81 g/kg),total phosphorus(2.92 g/kg),available nitrogen(38.52 mg/kg),available phosphorus(284.28 mg/kg)and organic carbon(144.10 g/kg).A total of 80 species were identified,primarily belonging to ascomycetes and basidiomycetes groups.Correlation analysis indicated that soil fungal community diversity was mainly influenced by soil's total nitrogen,total phosphorus,and or-ganic carbon content.In conclusion,combined application of sheep board manure and granular organic fertil-izer can effectively improve physical-chemical properties,and functional aspects related to fungal microbial communities enhance overall soil fertility and ecological environment within mining areas.
