我国正积极推进滨海盐碱地的开发利用，大力发展水稻生产。鉴于滨海盐碱地水稻生产高产栽培技术不够明晰，存在产量不高且不稳定等实际问题，我们系统总结了本团队在滨海盐碱地水稻高产形成与栽培技术方面的研究及实践工作。滨海盐碱地水稻高产形成的规律主要体现在以下方面：（1）需确保群体穗数充足且穗型较大，以此协同实现足够的群体库容量，并保持较高的库容充实度；（2）要稳定水稻前期生长量，合理增加中期光合生长量，显著增强后期干物质积累能力；（3）凭借良好的株型和群体支撑力，保障群体库容能够充分结实。围绕上述规律，我们针对性开展了一系列滨海盐碱地水稻高产栽培技术研究，涵盖土壤脱盐关键技术、土壤培肥关键技术、耐盐水稻品种筛选与鉴定、适宜的密肥组合与微咸水灌溉技术，以及外源生长调节剂的应用等方面。在此基础上，我们整合并形成了“耕、晒、泡、旋、排”多次循环与增施有机肥相结合的快速高效脱盐培肥技术，以及以应用耐盐优质品种和“早播、勤灌、壮秧、密植、足肥”为特征的机插综合栽培技术。通过这些技术的集成应用，构建了一套完整的滨海盐碱地机插水稻优质高产高效栽培技术体系，在滨海盐碱地取得了显著的改良土壤与增产效果。

China is actively promoting the development and utilization of coastal saline-alkali land to vigorously expand rice production. In view of the practical issues in rice production on coastal saline-alkali land, such as low and unstable yields and unclear high-yield cultivation techniques, we have systematically summarized our team’s research and practical work on the formation of high-yield rice and corresponding cultivation techniques in coastal saline-alkali land. The laws governing the formation of high-yield rice in coastal saline-alkali land are mainly manifested in the following three aspects: (1) Ensuring an adequate number of panicles per unit area with relatively large panicle size to collaboratively achieve a sufficient sink capacity of the population and maintain a high degree of sink filling; (2) Stabilizing the early-stage growth of rice, reasonably increasing the mid-stage photosynthetic growth, and significantly enhancing the dry matter accumulation capacity in the late stage; (3) Relying on good plant architecture and population support to ensure that the sink capacity of the population can be fully filled with grains. Based on these laws, we have conducted a series of targeted studies on high-yield cultivation techniques for rice in coastal saline-alkali land, covering such key technologies for soil desalination, key technologies for soil fertilization improvement, screening and identification of salt-tolerant rice varieties, appropriate density-fertilizer combinations and brackish water irrigation techniques, as well as the application of exogenous growth regulators. On this basis, we have integrated and developed a rapid and efficient desalination and fertilization improvement technique that combines multiple cycles of “plowing, sunning, soaking, rotary tilling, and draining” with the application of organic fertilizers, as well as a comprehensive mechanical transplantation cultivation technique characterized by the use of salt-tolerant and high-quality varieties and the practices of “early sowing, frequent irrigation, strong seedlings, dense planting, and sufficient fertilization.” Through the integrated application of these techniques, a complete set of high-quality, high-yield, and efficient mechanical transplantation cultivation techniques for rice in coastal saline-alkali land has been established, achieving remarkable effects in soil improvement and yield increase on coastal saline-alkali land.
