Abstract

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.

接种不同菌根真菌对蓝莓根瘤土壤真菌和养分吸收的影响
本研究旨在探讨接种不同真菌对土壤真菌群落结构特征和蓝莓植物养分吸收的影响。本研究选择了 DSE(Phialocephala fortinii)、SS(Penicillium pinophilum)、ZB(Cladosporium cladosporioides)、QMK(Chaetomium globosum)和 LZ(Schizophyllum commune)真菌。在接种了这些不同的菌根真菌后,对蓝莓根瘤菌圈中土壤真菌的多样性和群落结构进行了比较。接种 DSE、QMK 和 ZB 后,蓝莓根圈土壤中真菌的多样性明显高于接种 SS 和 LZ 后。土壤真菌的优势类、目、科和属分别为欧顶真菌纲(25.49-36.91%)、欧顶真菌纲(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 导致优势类、目、科和属的含量最高。接种 SS、LZ 和 DSE 增加了蓝莓植株中氮、磷和钾的含量。接种 DSE 的植株对氮、磷、钾的吸收率最高。接种 ZB 的植株的氮含量明显高于对照。TOPSIS分析表明,在五种真菌中,DSE是提高蓝莓根瘤菌群落多样性和促进蓝莓植物吸收养分的最佳菌株,其次是LZ和ZB。这些研究结果为土壤微生物资源的开发和利用提供了科学数据,并为改善蓝莓的栽培和生产提供了有用信息。
