The traditional manual seeding method is low in efficiency, high in labor intensity and low in seeding quality, and is difficult to meet the demand of large-scale production. Therefore, the plug tray seeder emerges as the times require, and high-efficiency seeding is realized through automation technology. Most of the currently used seeders are single-row air suction type needle plug tray seeders.
