Seeding of rapeseed by the use of vibration sowing device of a seeder
摘要
Vibration sowing device was developed for a seeder as the embodiment of multifunctional tilling and sowing machine. The main factors influencing the quality of seeding by vibration device are determined. According to research results, the graph of their influence on estimates of seeding is constructed. The parameters of efficient operation of the device are defined; they satisfy the agrotechnical requirements for the quality of small-seeded crops seeding.
