Research Progress on Nanosilicon-Mediated Alleviation of Salt Stress in Rice

doi:10.3969/j.issn.1006-8082.2026.02.006

Abstract

Abstract:

Soil salinization has led to a global average annual reduction in rice yield of over 30%, making the development of efficient salt-tolerant technologies an urgent priority. Nanosilicon, with its unique physicochemical properties and multi-target regulatory capabilities, has emerged as a promising strategy for alleviating salt stress in rice. This paper systematically reviews the effects of nanosilicon on rice growth and development, and elaborates on its physiological and ecological mechanisms in regulating rice growth and yield formation from multiple perspectives, including ion homeostasis, antioxidant defense systems, osmotic adjustment substance accumulation, photosynthetic machinery, and root system architecture. These insights provide a theoretical basis for promoting the large-scale application and sustainable management of nanosilicon in saline-alkali paddy fields. Finally, based on its characteristic of “high efficacy at low doses,” we further discuss the potential applications of nanosilicon in agroecosystems, as well as the major challenges currently faced.

Key words: rice, nanosilicon, salt stress

摘要：

土壤盐渍化导致全球水稻年均产量下降达30%以上，开发高效抗盐技术已成为当务之急。纳米硅因其独特的物理化学特性与多靶点调控能力，逐渐成为缓解水稻盐胁迫的重要新兴策略。本文系统综述了纳米硅对水稻生长发育的影响，从离子稳态、抗氧化防御系统、渗透调节物质积累、光合作用系统以及根系构型等多个层面，深入阐述了其调控水稻生长与产量形成的生理生态机制，为推动纳米硅在盐渍化稻田中的规模化应用与可持续治理提供理论依据。最后，基于其“低剂量、高效性”的特点，进一步探讨了纳米硅在农业生态系统中的潜在应用价值及当前面临的主要挑战。
