Abstract:

In order to provide a theoretical basis for rational application of organic fertilizers and ensure the healthy development of soil ecosystems in corn fields,the effects of soil fungal communities under different levels of organic fertilizer application for the composition,diversity,and functional characteristic were studied.In the meantime,a field experiment was used,with a total of 4 treatments were set up,and the high-throughput sequencing and FUNGuild method were used to analyze the soil fungal diversity,community structure and functional groups in different fertilization rates.The results showed that the increased application of organic fertilizer could increase the content of soil organic matter,available phosphorus,available potassium,urease,catalase,etc.,and it was positively correlated with the application amount of organic fertilizer.Applied organic fertilizers could increase the diversity of soil fungal communities and reduce their richness.The dominant fungal communities in the soil under different fertilization rates were Ascomycota,Mortierellomycota,Basidiomycota,and Olpidiomycota,the relative abundance of Ascomycota and Basidiomycota was significantly higher in the treatment with a medium amount of cattle manure than in the control without organic fertilizer;from the perspective of fungal genera,the dominant genera include Fusarium,Humicola,Olpidium,and Microidium.The application of organic fertilizer increased the relative abundance of symbiotic and saprophytic nutrients,and with the increase of organic fertilizer application,the abundance of pathological nutrients showed a decreasing trend;the number of woody saprophytic fungi in the treatment with increased organic fertilizer application was significantly higher than that in the treatment without organic fertilizer application,while the number of plant and animal pathogens was lower than the control.Therefore,it is believed that increasing a certain amount of organic fertilizer application could optimize the soil microbial environment and promote the increase of corn plant yield.
