中文摘要 | 草地作为陆地生态系统的重要组成部分,草地生态环境与国家生态安全息息相关。我国的草地退化问题日益严重,草地面积和产草量正在逐年减少,不仅影响了经济发展,同时还引发了水土流失、荒漠化等多种环境问题。目前迫切需要具有抗逆性强、适应性广等特点的优良生态草种,坚持自然恢复为主的方针,来改善草地退化现状,积极应对环境变化。野大麦(Hordeum brevisubulatum)广泛分布在我国盐碱化草甸上,其产量高,品质好,根系发达,抗旱耐寒、耐瘠薄、耐盐碱,内生真菌侵染后野大麦的抗性和适应性得到了进一步的提高。除放牧、刈割、青贮、加工草粉或调制干草外,在低湿地建立栽培草地或改良盐渍化土壤等方面颇有前途。本研究从野大麦优良特性、利用价值以及内生真菌对宿主野大麦生长、抗性和竞争力的影响3个方面进行综述,分析了野大麦-内生真菌作为生态草种的潜力,以期为野大麦-内生真菌共生体的深入研究和合理利用提供参考。 |
英文摘要 | Grassland is an important part of terrestrial ecosystems, and its ecological environment is closely related to national ecological security. However, the grassland degradation in China is becoming more serious, with grassland area and yield decreasing yearly, which not only affects the economic development, but also triggers various environmental problems, such as soil erosion and desertification. Thus, there is an urgent need for good ecological grass species with strong resistance and wide adaptability, while adhering to the principle of natural restoration, to improve the current situation of grassland degradation and actively respond to environmental changes. Wild barley (Hordeum brevisubulatum) is widely distributed in salinized meadows in China. It has high yield, good quality, well-developed root system, drought and cold tolerance, barren tolerance, salt-alkali tolerance, and an improved resistance and adaptability to endophytic fungal infection. In addition to grazing, mowing, silage, grass meal processing, or hay modulation, there is a promising future in establishing cultivated grasslands in low wetlands and in improving saline soil. This study summarized the excellent characteristics of wild barley, its utilization value, and the influence of endophytic fungi on its growth, resistance, and competitiveness. This study also analyzed its potential as an ecological grass species. An in-depth study and rational use of wild barley-endophytic fungus symbionts provide a reference. |
