The aim of this study was to explore the effects of inoculating with different fungi on the structural characteristics of soil fungal communities and the nutrient absorption of blueberry plants. The fungi DSE (Phialocephala fortinii), SS (Penicillium pinophilum), ZB (Cladosporium cladosporioides), QMK (Chaetomium globosum), and LZ (Schizophyllum commune) were selected for this study. The soil fungal diversity and community structure in the blueberry rhizosphere were compared after inoculation with these different mycorrhizal fungi. The fungal diversity in the blueberry rhizosphere soil was significantly higher after inoculation with DSE, QMK, and ZB than after inoculation with SS and LZ. The dominant class, order, family, and genus of soil fungi were Eurotiomycetes (25.49–36.91%), Eurotiales (24.78–35.00%), Aspergillaceae (24.47–34.74%), and Penicllium (24.34–34.63%), respectively. Among all the fungal treatments, DSE led to the highest abundance of dominant classes, orders, families, and genera. Inoculation with SS, LZ, and DSE increased the contents of nitrogen, phosphorus, and potassium in blueberry plants. The uptake of nitrogen, phosphorus, and potassium were highest in DSE-inoculated plants. The nitrogen content was significantly higher in ZB-inoculated plants than in the control. A TOPSIS analysis showed that among the five fungi, DSE was the best strain to improve the diversity of the blueberry rhizosphere fungal community and promote nutrient uptake by blueberry plants, followed by LZ and ZB. These findings provide scientific data for the development and utilization of soil microbial resources, and provide useful information for improving the cultivation and production of blueberries.

本研究旨在探讨接种不同真菌对土壤真菌群落结构特征及蓝莓植株养分吸收的影响。本研究选择真菌 DSE ( Phialocephala fortinii )、SS ( Penicillium pinophilum )、ZB ( Cladosporium cladosporioides )、QMK ( Chaetomium globosum ) 和 LZ ( Schizophyllum commune )。比较接种不同菌根真菌后蓝莓根际土壤真菌多样性和群落结构。接种DSE、QMK和ZB后蓝莓根际土壤真菌多样性显着高于接种SS和LZ后。土壤真菌的优势纲、目、科、属分别为伞菌纲（25.49-36.91%）、伞菌目（24.78-35.00%）、曲霉科（24.47-34.74%）和青霉属（24.34-34.63%）。在所有真菌处理中，DSE 导致优势纲、目、科和属的丰度最高。接种SS、LZ和DSE提高了蓝莓植株的氮、磷和钾含量。接种 DSE 的植物对氮、磷和钾的吸收最高。接种 ZB 的植物中的氮含量显着高于对照植物。TOPSIS分析表明，5种真菌中，DSE是提高蓝莓根际真菌群落多样性、促进蓝莓植株吸收​​养分效果最好的菌株，其次是LZ和ZB。这些研究结果为土壤微生物资源的开发利用提供了科学数据，为提高蓝莓的栽培和生产提供了有用的信息。
