The work aims to screen dominant fungal species in the atmospheric environment of Xisha Experimental Station and conduct research on sensitive fungal in Xisha Experimental Station equipment.The impact method was used for sampling atmospheric fungi,and statistical methods were used to calculate the number of fungi in different experimental sites.Morpho-logical methods were used,the species were identified in combination with ITS1-5.8S-TIS2 or 26S rDNA D1/D2 region se-quence analysis.SPSS was used to preliminarily explore the relationship between atmospheric fungi and environmental factors,and to analyze the sensitive fungi in Xisha Experimental Station equipment.The dominant species at the Xisha Experimental Station were Aspergillus aculatus,Penicillium citrinum,Pithomyces sacchar,Fusarium incarnatum,Cladosporium oxysporum,and Cladosporium oryzae.The important environmental factors affecting the structure of the atmospheric mold community at Xisha Experimental Station were relative humidity and wind speed.Equipment stored in Xisha Experimental Station was prone to mold growth,and various materials had different sensitive fungi,especially for coating samples and rubber materials.There are various types of fungi in the atmospheric environment of Xisha Experimental Station.
