摘要:

丛枝菌根真菌(AMF)广泛分布于陆地生态系统中, 可与大多数植物形成共生关系, 并通过根外菌丝网络介导植物-土壤互作, 在提升陆地生态系统生产力、维持生物多样性和土壤健康方面发挥着不可替代的作用。尽管AMF在植物营养吸收与逆境响应中的生理功能已被广泛证实, 但其在生态系统尺度上的功能仍缺乏系统评估, 而且缺乏有效的AMF群落调控技术。该文从生态系统生产力、生物多样性和系统稳定性、元素生物地球化学循环和土壤健康四个方面系统总结了AMF的生态功能。针对当前AMF群落定向调控的技术瓶颈, 提出构建“土著菌群激活—外源菌剂增效—管理技术适配”三位一体的生态调控框架, 旨在构建以AMF为核心的土壤生态调控技术体系, 促进菌根技术在应对全球变化与支撑农业可持续发展中的规模化应用。考虑到AMF群落定向调控面临的多重挑战, 未来研究亟需解析AMF-植物-环境多维互作体系, 研发菌群调控技术和多功能复合菌剂, 通过长期定位实验优化田间管理方案, 实现菌根技术在生态恢复工程和可持续农业中的体系化应用。

Abstract:

Arbuscular mycorrhizal fungi (AMF), widely distributed in terrestrial ecosystems, form symbiotic associations with most terrestrial plants. Their extraradical hyphal networks mediate plant-soil interactions, playing indispensable roles in enhancing ecosystem productivity, sustaining biodiversity, and maintaining soil health. While the roles of AMF in enhancing plant nutrient acquisition and stress tolerance are well documented, comprehensive assessments of their ecosystem-scale functions remain scarce. More importantly, methodologies for the targeted manipulation of AMF communities and their ecological functions are still underdeveloped. This review systematically summarizes the ecological functions of AMF from four aspects: ecosystem productivity, biodiversity-ecosystem stability relationships, biogeochemical cycling, and soil health. To address current technical bottlenecks in AMF community regulation, we propose an ecological regulation framework for the application of AMF in improvement of ecosystem functions, including the activation of indigenous fungal consortia, the application of exogenous inoculants, and optimizing context-specific management practices. This framework refines a robust, AMF-centered soil ecological regulation paradigm to facilitate the development of mycorrhizal technologies. Future studies should prioritize the multidimensional interactions among AMF, host plants, and environmental factors, to address the multiple challenges associated with the targeted regulation of AMF communities. This includes advancing microbial regulation strategies, developing multifunctional consortia, and optimizing long-term field management practices. Ultimately, these efforts aim to promote the effective application of mycorrhizal technologies in ecological restoration and sustainable agriculture.
