As core equipment for precision agriculture, precision seeders directly impact the sustainability and economic efficiency of modern agriculture. With the increasing demands for precision farming and high-speed operation, precision seeders featuring state-of-the-art mechanical designs, multi-source data fusion, and flexible system expansion have become the current research trend. This paper reviews the research status and development trends, focusing on advanced mechanical design, precise control, and adjustability: (1) innovative mechanical structures, including seeding unit, driving system, and sensing system of precision seeders; (2) precision control technologies, including seed spacing, seeding depth, trajectory control, and monitoring; (3) flexible system extensibility, such as multi-crop adaptability and multi-functional integration. After systematically reviewing and analyzing these technologies, this paper further discusses the current development status, identifies existing challenges, and explores future trends in precision seeders, offering valuable insights for the advancement of precision seeders and the intelligent transformation of agriculture.
