摘要:

土壤盐碱化是当前全球粮食安全面临的主要挑战之一,水稻是滨海滩涂和盐碱地改良首选的粮食作物,提高耐盐性对稳定盐碱地水稻生产至关重要。促生微生物是生物改良土壤盐碱化的重要组成部分。耐盐型促生微生物如丛枝菌根真菌、芽孢杆菌和假单胞菌等,可以通过激活土壤酶活性、生成胞外多糖、增强抗氧化酶活性、调节渗透代谢、调节植物激素等方式来缓解盐胁迫对水稻的生长发育造成不利影响。本文总结了上述三种促生微生物提高盐胁迫下水稻抗性的不同途径和相关机理,指出现阶段研究领域存在的欠缺并对今后的研究提出展望,以期为盐碱地改良和水稻高产提供理论和实践依据。

Abstract:

Soil salinization is one of the main challenges facing global food security. Rice is the preferred grain crop for the reclamation of coastal tidal flats and saline-alkaline land. Enhancing salt tolerance is essential to ensuring stable saline-alkaline soil rice production. Plant growth-promoting microorganisms (PGPMs) are a crucial part of the biological improvement of saline-alkaline soils. Salt-tolerant PGPMs, such as arbuscular mycorrhizal fungi, Bacillus, and Pseudomonas, can alleviate the adverse effects of salt stress on the growth and development of rice by activating soil enzyme activity, producing extracellular polysaccharides, enhancing antioxidant enzyme activity, regulating osmotic metabolism osmoprotectants, and regulating plant hormones. This work summarizes different pathways and related mechanisms by which the three aforementioned PGPMs enhance rice resistance under salt stress, highlights the current research gaps in this field, and provides an outlook for future research, thereby offering theoretical and practical bases for the improvement of saline-alkaline soils and high-yield rice production.
