水稻品种改良与耐盐碱地栽培技术研究
摘 要
水稻作为全球重要的粮食作物之一，其产量和品质直接关系到粮食安全。然而，随着全球气候变化和土地资源退化，盐碱地面积不断扩大，严重制约了水稻的种植。本研究旨在通过品种改良与耐盐碱地栽培技术的结合，提升水稻在盐碱环境中的适应性和产量。研究首先筛选了多个具有潜在耐盐碱特性的水稻品种，并通过实验室和田间试验对其耐盐碱能力进行了系统评估。结果表明，部分品种在盐浓度为10‰的条件下仍能保持较高的生长速率和产量，显著优于传统品种。在此基础上，研究进一步优化了耐盐碱栽培技术，包括土壤改良、灌溉管理及施肥策略等。通过对比试验发现，采用优化后的栽培技术可使水稻产量提高20%-30%。

STUDY ON RICE VARIETY IMPROVEMENT AND SALINE-ALKALI TOLERANT CULTIVATION TECHNIQUES
ABSTRACT
As one of the most important food crops in the world, the yield and quality of rice are directly related to food security. However, with global climate change and land resource degradation, the area of saline-alkali land is expanding, seriously restricting the cultivation of rice. This study aims to improve the adaptability and yield of rice in the saline environment through the combination of variety improvement and saline-tolerant cultivation techniques. The study first screened multiple rice varieties with potential salinity tolerance properties, and their salinity tolerance capacity was systematically evaluated by laboratory and field experiments. The results showed that some varieties can still maintain a high growth rate and yield under the salt concentration of 10 ‰, which is significantly better than the traditional varieties. On this basis, the study further optimized the salinity-tolerant cultivation techniques, including soil improvement, irrigation management and fertilization strategies. The comparative experiment found that the optimized cultivation technique can increase the rice yield by 20% -30%.
