Abstract: Arbuscular mycorrhizae are important parts of the grassland ecosystem. In this paper, the roles of arbuscular mycorrhizae in nutrient absorption, stress resistance, growth, competition and coexistence of forage grasses, as well as the community structure adjustment, and productivity increase are summarized. Related research of mycorrhizae conducted in our country are prospected, such as: investigating mycorrhizal symbiotic and dependent characteristic of main forage grass; the effects of mycorrhizae on forage grass competition; screening highly efficient fungi and applied technology; the comprehensive effects of mycorrhizae on the ecosystem; the influences of mycorrhizae on plant competition; the reciprocity of grassland management and mycorrhizal effects; the function of mycorrhizae on restoring degenerated grassland vegetation; the effects of mycorrhizae on remediation of contaminated soil; the establishment of grassland mycorrhizal resources database in our country.

摘要: 丛枝菌根是草地生态系统的重要组成部分,其对系统的重要作用日益引起人们的广泛关注。为促进相关研究,本文综述了丛枝菌对牧草养分吸收、抗逆性、生长发育以及对草地生态系统中牧草间竞争与共存、群落结构调节、提高草地生产力等的重要作用。针对我国当前相关的研究:即主要牧草进行菌根共生特性与菌根依赖性的调查研究、菌根对牧草竞争的影响研究、高效菌种筛选与接种应用技术的开发研究、对草地生态系统进行丛枝菌根综合效应的研究、菌根对牧草竞争的影响研究、草地管理与菌根效应相互关系的研究、丛枝菌根对退化草地植被恢复的作用研究、污染草地土壤菌根修复的研究、草地丛枝菌根资源库的建立等进行了展望。
