摘要： In order to realize the utilization of Moutai lees and the improvement of soil fertility of yellow soil in Guizhou, a field experiment was carried out to study the effects of short-term application of Moutai lees biochar on nutrients and fungal community structure diversity of yellow soil. The results showed that the application of Moutai lees biochar increased the pH, soil organic matter (SOM), total nitrogen (TN), ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3--N), available phosphorus (AP), and available potassium (AK), while the microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) were reduced. The application of biochar significantly reduced the number of fungal OTU and community diversity. The application of biochar increased the relative abundances of Chytridiomycota and Mortierellomycota, while the relative abundance of Ascomycota was significantly reduced. Redundancy analysis (RDA) suggested that SOM, NH4+-N and NO3--N were the key factors correlated with changes in microbial community structure. Overall, the short-term application of lees biochar can not only improve the nutrient content of yellow soil, but also change the structure and diversity of soil fungal communities. More importantly, Moutai lees biochar can reduce the relative abundance of some pathogenic fungi and play the role of inhibiting the growth and reproduction of harmful plant pathogens.
