Mechanism of Comprehensive Utilization of Saline-Alkali Land in Improving Grain Production Capacity
盐碱地综合利用对粮食产能提升的作用机制

摘要

盐碱地综合利用是拓展农业生产空间、提高耕地质量和增强粮食供给能力的重要方式。盐碱地类型复 杂，粮食产能受到土壤盐分、碱化程度、水资源条件和治理成本等因素制约。其产能提升并非单纯依赖土地开发， 而是通过增加适宜耕地、改善土壤环境、培育耐盐碱品种和优化水肥管理共同实现。依据资源承载能力推进 分区利用，构建良田、良种、良法协同体系，有利于盐碱地形成稳定、可持续的粮食产能。

Abstract

The comprehensive utilization of saline-alkali land is an important way to expand agricultural production space, improve cultivated land quality, and enhance grain supply capacity. Saline-alkali land is complex in type, and its grain production capacity is constrained by factors such as soil salinity, alkalization degree, water resource conditions, and governance costs. The improvement of its production capacity does not simply depend on land development, but is jointly realized through increasing suitable cultivated land, improving the soil environment, breeding saline-alkali tolerant varieties, and optimizing water and fertilizer management. Promoting zoned utilization according to resource carrying capacity and building a coordinated system of high-quality farmland, improved varieties, and effective agronomic methods are conducive to forming stable and sustainable grain production capacity on saline-alkali land.
