Effects of no-tillage, mulching, and organic fertilization on soil fungal community composition and diversity
We examined the responses of soil fungal community to no-tillage, mulching, and organic fertilization by setting up different treatments for three years in winter wheat land in mountain areas of southern Ningxia, including no-tillage, mulching and organic fertilization (NF), no-tillage, mulching and no organic fertilization (NC), conventional tillage without mulching and organic fertilization (TF), and conventional tillage without mulching and no organic fertilization (TC). Based on Illumina Miseq high-throughput sequencing platform, the relationship between the composition and diversity of soil fungal community and soil environmental factors were examined. A total of 3490 fungal OTUs were obtained from four treatments, which included some unidentified or unknown fungi. In the identified ones, Ascomycota and Basidiomycota were the dominant phylum, contributing to 82.1%-94.2% of the total abundance. The relative abundance of Dothideomycetes from Ascomycota was the highest under TF, while that of Tremellomycetes from Basidiomycota was highest under NF. Both Shannon and Simpson indices of soil fungal community were in order of NC>TC>NF>TF. The results of multivariate analysis showed that soil microbial biomass carbon was the main factor affecting the relative abundance of Basidiomycota and Zygomycotabased at the phylum level, while soil total phosphorus, available potassium, and available phosphorus were key factors driving the changes of relative abundance of Ascomycota. Therefore, popularizing of conservation tillage based on the no-tillage, mulching and organic fertilization technology would be beneficial to the diversity of soil fungal community in mountainou areas of southern Ningxia.
