is an important ectomycorrhizal edible fungus whose economic and nutritional value are both high. To better understand which abiotic and biotic factors affect the growth of , this study examined the mycosphere soil of growing in five sites. The soil fungal communities of from five sites of Fujian, Guangxi, and Yunnan Provinces were sequenced by Illumina MiSeq technology, and their community structure comprehensively analyzed in combination with a suite of soil physicochemical properties. The results revealed significantly greater levels of available potassium (AK), available nitrogen (AN), and available phosphorus (AP) in mycosphere soil than bulk soil, and that prefers acidic soil, with , , , , , , , and being the main dominant fungal taxa. Different geographical sites had different indicator fungal genera, and the similarity of fungal communities in the mycosphere decreased with increasing geographical distance among them. Soil pH was the major abiotic factor influencing the structure of the mycosphere fungal communities. Management strategies such as nitrogen, potassium, phosphorus mixed fertilizer, and fungal fertilizer can promote the conservation and sustainable utilization of .
是一种重要的外生菌根食用菌，具有很高的经济价值和营养价值。为了更好地了解哪些非生物和生物因素影响其生长，本研究调查了在五个地点生长的其菌根际土壤。利用Illumina MiSeq技术对来自福建、广西和云南三省五个地点的其土壤真菌群落进行测序，并结合一系列土壤理化性质对其群落结构进行综合分析。结果表明，菌根际土壤中有效钾（AK）、有效氮（AN）和有效磷（AP）的含量显著高于原状土，且其偏好酸性土壤，其中，、、、、、、和为主要优势真菌类群。不同地理地点有不同的指示真菌属，且菌根际真菌群落的相似性随着它们之间地理距离的增加而降低。土壤pH是影响菌根际真菌群落结构的主要非生物因素。氮、钾、磷复合肥和菌肥等管理策略可以促进其保护和可持续利用。
