Abstract：To study the fungal community structure of cigar rhizosphere soil under different fertilization treatments,and to provide a basis for rational fertilization of cigars,this study used cigar variety Haiyan 204 as test crop,chemical fertilizer and two organic fertilizers,soybean cake and fish protein,were selected.A three-factor three-level orthogonal experimental design was employed with a total of 9 treatments,and each replica-ted 3 times.High-throughput sequencing was conducted using Illumina NovaSeq 6000 to analyze the structure,diversity and differences of fungal communities in cigar rhizosphere soil under different fertilization treatments.The results indicated that Ascomycota was the dominant fungi phylum in cigar rhizosphere soil under different fertilization treatments,and T5 treatment(N 150 kg/hm2+fish protein 15 L/hm2+soybean cake 1 500 kg/hm2)had the highest relative abundance.The relative abundance of dominant genera(Mortierella and Conocybe)under different combination treatments was higher than that under single fertilizer treatment.The combination of organic and inorganic fertilizers increased the proportion of soil saprophytic bacteria,which was more conducive to the stability and health of soil ecosystems.The research results could provide references for the rational application of organic and inorganic fertilizers in the production process of cigar.
