At present, most of the foreign seeders are suitable for large farms, which have high requirements for land flatness. They are generally large machines and expensive. Domestic seeders are mostly small machines that can meet the seeding requirements. They are relatively cheap, but have single functions, uneven seeding, poor operation results, and low rapeseed yields, which cannot meet the requirements of agricultural mechanization development in my country. The existing seeders have low seeding accuracy and single functions, which leads to complex production processes and high production costs for farmers. On the other hand, large machines are basically used in the harvesting process of agricultural products. The waste straw after harvesting is basically discarded in the field. These waste straws can be used as fertilizers, but because the waste straw is evenly spread in the field, the large amount of straw will affect the sowing of rapeseed, especially when working in rice stubble fields. Because the fields have large amounts of straw and high soil moisture content, the operation quality of general machines is difficult to guarantee.
