Abstract: Intelligent precision seeder is an automated agricultural equipment that can significantly improve planting efficiency and reduce planting cost. However, the current intelligent precision seeder relies on high-precision sensors, control systems and algorithms to achieve accurate seed placement and depth control, which requires high technical requirements and technical support, and is poorly adapted to some irregularly shaped seeds or large and small seeds. Therefore, this study proposes an optimized solution for an intelligent precision seeder. This study uses high-precision sensors and control systems, achieves multi-functional seeding, controls seed placement and adjusts seeding depth, uses energy-efficient equipment, modular design and easily replaceable components, data analysis function and easy-to-use user interface.Finally conducts functional tests through field trials, and the results show that the optimized intelligent precision seeder sowing coefficient of variation ≤ 5% and met the agronomic requirements for sowing. The research results can achieve accurate seed placement and depth control to avoid problems such as uneven planting density and inconsistent depth, thus improving planting efficiency and crop quality.
