Current Status and Future Directions for Combined Tillage and Sowing Technology and Equipment

As the focus of the development of mechanized tillage and sowing, combined tillage and sowing machines have a variety of functions, such as seedbed preparation, fertilizer sowing, and pressing. Compared with the traditional single-function planter, these machines effectively shorten the operation cycle, reduce production costs, and promote increased production and income. This paper categorizes the machines into these combined rotary tillage and sowing machine, the combined disk harrow and sowing machine, and the combined multi-link tillage and sowing machine according to the form of the tillage and operation. It also systematically elaborates on the technical characteristics, application scenarios, and operational requirements of different types of combined tillage and sowing machines. Additionally, this paper outlines key technologies, such as seedbed preparation and precision sowing. Considering the current state of scientific and technological advancements and the practical needs of agricultural production, it also suggests future research directions and trends, offering valuable insights for subsequent studies in this field.
