Abstract

Abstract:

Currently, China’s food security still faces a relatively prominent contradiction among “population, land, and grain”. China has 2.34 million hm² of coastal saline-alkali land and 100 million hm² of inland saline-alkali land. These saline-alkali lands are rare reserve land resources with enormous potential for comprehensive utilization. Rice is often selected as a key crop for soil improvement in both coastal and inland saline-alkali lands. It can continuously play a special role in integrating “utilization, improvement, and conservation” to gradually optimize the soil. In recent years, indica-japonica hybrid rice has repeatedly set high-yield records in production practices, demonstrating extremely broad prospects for production and application. This paper first provides a systematic review of the impacts of salt stress on rice yield and its components, material production capacity, plant type morphological characteristics, and leaf photosynthetic physiological traits. Secondly, it deeply reveals the morphological and physiological characteristics underlying the yield advantage formation of indica-japonica hybrid rice in coastal saline-alkali land and proposes targeted key cultivation measures for high-yield cultivation of indica-japonica hybrid rice in coastal saline-alkali land. Finally, it discusses and prospects the research on strengthening the mechanism of high-yield cultivation of indica-japonica hybrid rice in coastal saline-alkali land, aiming to provide solid theoretical and technical support for high-yield cultivation and regulation management.

Key words: coastal saline-alkali land, indica-japonica hybrid rice, salt stress, yield formation

摘要：

当前，我国粮食安全仍面临着较为突出的“人、地、粮”矛盾。我国拥有234万hm²滨海盐碱地以及1亿hm²内陆盐碱地，这些盐碱地是不可多得的土地后备资源，具有极大的综合利用潜力。水稻常被选作滨海盐碱地和内陆盐碱地土壤改良的关键作物，它能够持续发挥“用、改、养”一体化的特殊作用，实现土壤的逐步优化。近年来，籼粳杂交稻在生产实践中屡创高产纪录，展现出极为广阔的生产应用前景。本文首先系统综述了盐胁迫对水稻产量及其构成要素、物质生产能力、株型形态特征以及叶片光合生理特性等方面的影响；其次，深入揭示了滨海盐碱地籼粳杂交稻产量优势形成的形态与生理特性，并针对性地提出了滨海盐碱地籼粳杂交稻丰产的关键栽培措施；最后，对加强滨海盐碱地籼粳杂交稻丰产栽培的机制研究展开了讨论与展望，旨在为其丰产栽培与调控管理提供坚实的理论与技术支撑。
