摘　　要：兰科植物是典型的菌根植物。兰菌根是兰科植物根与真菌形成的菌根共生体。兰菌根真菌的营养来源影响宿主植物的生活方式和营养水平。氮是植物生长的主要限制因子。兰科植物具有富集氮的特征,其组织和器官的氮含量通常高于同生境中的其他植物。该文综述了兰菌根真菌类别、兰科植物氮营养特征和兰菌根的氮转移机制等的研究进展,以期为兰科植物资源的保护、再生及可持续利用的相关研究提供参考和借鉴。Orchid is typical of mycorrhizal plants. Orchid mycorrhiza(OM), the symbiotic association between orchid roots and fungi, is unique to orchids. The nutrient sources of orchid mycorrhizal fungi(OMF) affect the lifestyle and nutrient levels of its host plants. Nitrogen(N) is the main limiting factor of plant growth. Orchids generally have higher tissue N levels compared to neighbor autotrophic plants, meaning N enrichment of plants. This paper reviewed the types and taxa of OMF, N nutrition characteristics of orchids, and N transfer mechanism in OM to provide a reference for the research on protection, regeneration, and sustainable utilization of orchid resources.
