水稻是我国重要的粮食作物，其产量高低直接关乎国家粮食安全。协调水稻安全生产、生态环境保护和资源高效利用，已成为我国乃至全球农业可持续发展领域所面临的重点与难点。水稻机插侧深施肥技术将肥料侧深施用与水稻秧苗的机械移栽融为一体，有效替代了传统撒施肥料方式，具有显著提升肥料利用率、促进水稻生长发育和提高产量等优点。基于作者所在团队多年来的深入研究与丰富实践，紧密围绕侧深施肥技术的发展历程、核心技术要点、限制因素以及相应的参考建议等方面，综述了水稻机插侧深施肥技术的研究现状及未来发展趋势。在推广机插侧深施肥技术过程中，应当重视政策扶持与技术创新的有机结合，实现水稻安全生产、生态环境保护和资源高效利用协调发展，为我国农业向环境友好型和绿色可持续生产模式转型提供支持。

Rice is one of the important food crops in China, and its yield directly affects national food security. Coordinating the safe production of rice, ecological environmental protection, and efficient utilization of resources has become a key and difficult issue faced in the field of sustainable agricultural development in China and even globally. The side deep fertilization technology for rice mechanical transplanting integrates the side deep application of fertilizer with the mechanical transplanting of rice seedlings, effectively replacing the traditional broadcast fertilization method. It has significant advantages such as improving fertilizer utilization efficiency, promoting the growth and development of rice, and increasing yield. Based on the team’s years of in-depth research and rich practical experience, this paper reviewed the research status and future development trends of side deep fertilization technology for rice mechanical transplanting, focusing on the development history, core technical points, existing constraints, and corresponding reference suggestions. In the process of promoting the side deep fertilization technology for mechanical transplanting, attention should be paid to the organic combination of policy support and technological innovation, to achieve the coordinated development of rice safety production, ecological environmental protection, and efficient resource utilization, providing a reference for the transformation of China’s agriculture towards an environmentally friendly and green sustainable production model.
