The first planter was made in Greece in 1636. In 1830, the Russians made a plow on an animal-powered multishare plow. After 1860, Britain and the United States and other countries began to mass-produce animal-powered grain drills. After the 20th century, there have been traction and hanging grain drills, as well as seed drills that use pneumatic seeding. The development of precision seeders in the 1950s. China introduced grain drills, cotton seeders, etc. from the 1950s. In the 1960s, various types of hanging grain planters, centrifugal planters, universal rack planters and air-suction planters were developed successively, and a milled seed meter was developed. By the 1970s, two series of general-purpose seeding cultivators and grain combined seeders had been formed, and precision seeders had been successfully developed at the same time.
Planters plant seeds of crops or coated seeds made into pellets. It can be divided into three categories according to the sowing method: vacuum seed seeder spreader, drill seeder and hole seeder. Various types of precision seeders, which have been developed in large numbers since the 1950s, can precisely control the seeding rate, hole (plant) spacing and sowing depth. The pneumatic seed metering precision seeder developed in the 1970s, its seed metering device (air suction type, air pressure type or air blowing type) uses positive or negative pressure airflow to discharge a row of seeds at a certain interval to achieve single-grain precision hole seeding. Compared with the traditional mechanical seed metering device, it has the characteristics of accurate sowing and no damage to the seeds. In addition, there is a mechanical precision seed metering device. It is a hanging 6-row row crop planter with fertilization device, which can be used for drilling and hole sowing of row crops such as soybean, corn and sorghum.
