Data Sheet 1_Single-season responses of rhizosphere fungal community structure and diversity to combined application of different organic materials in potato.docx Lianglu Hao (25102204) Xinyuan Hu (6096383) Bo Dong (218172) Shiqian Guo (11584666) Dandan Du (8196840) Li Jia (76051) Jian Wen (286688) Microbiology fungal community structure fungal diversity organic materials potato rhizosphere soil <p>Long-term application of chemical fertilizers can lead to a decline in soil microbial diversity and an imbalance in community structure, thereby constraining the sustainable development of the potato industry. In this study, a single-season field experiment was conducted in Yongdeng County, Lanzhou City, Gansu Province, with four treatments: chemical fertilizer alone (CF), sheep manure combined with chemical fertilizer (T1), biochar combined with chemical fertilizer (T2), and corn stover combined with chemical fertilizer (T3). High-throughput sequencing was employed to investigate the single-season responses of fungal community structure and diversity in potato rhizosphere soil to different combined application patterns of organic materials and chemical fertilizers. The results showed that: (1) compared with CF, the T1, T2, and T3 treatments significantly increased soil organic matter, available phosphorus, and total nitrogen contents, but had no significant effects on soil pH, total phosphorus, or total potassium. Crop yield was significantly increased in the T1 and T2 treatments compared with CF, whereas no significant difference was observed in the T3 treatment. (2) Compared with CF, the Chao index was significantly increased in the T2 and T3 treatments, and the Shannon index was significantly increased in the T1, T2, and T3 treatments. Beta diversity analysis revealed that the T1, T2, and T3 treatments all induced significant changes in fungal community structure, with T1 and T3 exhibiting relatively high similarity in community composition. (3) Compared with CF, the T3 treatment significantly increased the relative abundances of Alternaria and Mortierella while decreasing that of Pseudogymnoascus; the T2 treatment significantly increased the relative abundance of Mortierella and decreased that of Pseudogymnoascus; and the T1 treatment significantly increased the relative abundance of Scutellinia. (4) LEfSe analysis revealed that the T2 treatment harbored the highest number of differentially abundant fungal taxa (8 species). Redundancy analysis identified soil total nitrogen as the most important environmental driver shaping fungal community variation. In summary, under the single-season conditions of this experiment, the T2 treatment exhibited the best performance in enhancing both potato yield and fungal diversity; however, its long-term effects require further validation.</p> 2026-09-24T05:33:04Z Dataset Dataset 10.3389/fmicb.2026.1853956.s001 https://figshare.com/articles/dataset/Data_Sheet_1_Single-season_responses_of_rhizosphere_fungal_community_structure_and_diversity_to_combined_application_of_different_organic_materials_in_potato_docx/33979882 CC BY 4.0
