Introduction To The Planter
- Jul 10, 2018 -

The first planter was made in Greece in 1636. In 1830, the Russians made plows on the plows of animal power. After 1860, countries such as the United Kingdom and the United States began mass production of animal grain grain drills. After the 20th century, traction and hanging grain drills were introduced, as well as seed drills using pneumatic seeding. Developed precision seeders in the 1950s. China introduced grain drills and cotton planters from the 1950s. In the 1960s, it developed into a variety of types such as suspended grain seeders, centrifugal seeders, universal rack seeders and air suction planters, and developed into a milled seed metering device. By the 1970s, two series of sowing cultivators and grain combine planters had been formed, and precision seeders were successfully developed.

The planter is planted with seeds of the crop or coated seeds in the form of pellets. It can be divided into three types according to the sowing method: vacuum seed drill spreader, drill and hole drill. Various types of precision planters, which have been extensively developed since the 1950s, can precisely control the amount of seeding, the distance between the acupoints and the depth of sowing. The precision seed drills developed in the 1970s, the seed metering device (air suction type, pneumatic type or air blowing type) uses a positive pressure or a negative pressure air flow to discharge a column of seeds at a certain interval to achieve a single precision hole seeding, and Compared with the traditional mechanical seed metering device, it has the characteristics of accurate sowing amount and no damage to seeds. There is also a mechanical precision seed metering device. It is a suspended 6-row row crop planter with fertilizer application, which can be used for seeding and hole planting of cultivating crops such as soybean, corn and sorghum.
