Xanthoceras sorbifolia Bunge, as a kind of woody oil tree species with barren resistance,drought resistance and saline-alkali resistance, is widely distributed in northern China. Soil microorganisms are important decomposers with a large number and a wide range of species. They play an important role in material circulation and energy flow, and their role in the ecological environment cannot be underestimated.[Objective]In recent years, with the in-depth study of the functional value of Xanthoceras sorbifolia Bunge, its soil microbial research has gradually become a hot spot. These microorganisms are not only closely related to the growth and nutrient absorption of Xanthoceras sorbifolia Bunge, but also may have an important impact on its stress resistance, yield and quality. Through in-depth and systematic study of the morphological characteristics, ecological habits, planting status and suitable soil characteristics of Xanthoceras sorbifolia, the research process and important findings of soil microorganisms in Xanth oceras sorbifolia were analyzed, and the types, functions, influencing factors and research techniques of soil microorganisms were summarized. The key role of Xanthoceras sorbifolia soil microorganisms in ecosystem services, fundamentally understand the growth mechanism of Xanthoceras sorbifolia, and provide scientific significance and practical application value for optimizing the cultivation and management of Xanthoceras sorbifolia, improving soil productivity and sustainable development of Xanthoceras sorbifolia industry.[Research progress]At present, the research on soil microorganisms of Xanthoceras sorbifolia mainly focuses on the microbial community structure of rhizosphere soil microorganisms, root endophytic fungi and root nodules of Xanthoceras sorbifolia and their effects on plant growth and soil nutrient cycling. From the traditional pure culture technology to modern molecular biology technology, and then to the development of multi-omics research, the community structure and function of soil microorganisms and their role in the ecosystem were analyzed by using various and efficient research methods and techniques,and the potential effects of soil microorganisms on the growth and ecological environment of Xanthoceras sorbifolia were summarized. [Development direction] In the future, we should further explore the metabolic capacity and ecological function of Xanthoceras sorbifolia soil microorganisms, study the interaction mechanism between Xanthoceras sorbifolia roots and soil microorganisms, analyze the response mechanism of Xanthoceras sorbifolia soil microorganisms to different environmental pressures, such as drought,saline-alkali, heavy metal pollution and other environmental stress resistance, and develop special microbial fertilizer for Xanthoceras sorbifolia, so as to improve soil, increase the yield and quality of Xanthoceras sorbifolia, and provide more scientific and comprehensive theoretical support and technical guidance for the efficient and sustainable planting of Xanthoceras sorbifolia.
