Footnote 2: email: {H.Y. environments, and crop-planting requirements, the soil is modified through different forms of mechanized tillage, so that crops can obtain a more suitable growth environment, thereby improving sowing quality and increasing crop yields [5, 6, 7]. Mechanized tillage and sowing mainly include rotary tillage, subsoiling, ridging and sowing, and other essential elements. The emergence and application of various agricultural machineries in agricultural production have reduced human labor and improved operational efficiency. However, due to the production process's complexity, single mechanized tillage methods such as rotary tillage, subsoiling, and sowing can lead to multiple entries of tractors and work tools into the field, resulting in soil compaction [8, 9, 10, 11]. This method not only has low operating efficiency and higher operating costs for machinery but also destroys the soil structure, reduces soil quality, and adversely affects crop growth. Problems such as reduced fertility and the lower transport efficiency of air, water, and nutrients stored in the soil are generated, thus leading to reduced crop yields [12, 13, 14]. To solve the problems arising from mechanized cultivation and sowing operations, research on combined tillage and sowing machines has become the focus of mechanized agricultural development. The machine is a production machine that carries out multi-linked tandem and orderly operations around the sowing operation, which can realize the operations of tillage, furrowing, fertilizer application, and pressing in one go, finely crushing the soil, forming an ideal seeded, providing an excellent environment for the seed growth base, realizing highly efficient and precise sowing operations, and promoting the growth and increase in crop income. It also optimizes the form of tillage by integrating the operation process, effectively reduces the compaction damage to the soil, improves the ecological environment of farmland, and is significant for sustainable agricultural production. Combined tillage and sowing machines can significantly reduce operational expenses and production cycles, streamline production processes, mitigate soil compaction, preserve soil structure, prevent soil erosion and sanding, and improve soil quality. These advantages ultimately lead to increased crop yields. The relevant research shows that operational efficiency increased by 30% compared to the traditional machine, and yield increased by 10-13% [5, 15, 16, 17, 18].
