摘  要：
Tray seeding is the key technology and step of growing seedlings in tray. An air-suction seedling and seeding device in tray was designed for small-scale planting farmers. It has simpler structure,lower cost,and is easily used. Its basic structure and theory were introduced. Seed sucking tray and its motion controlling mechanism,and structure and parameters of exhaust system were designed and calculated. On this basis,the prototype seeder was manufactured and tested with melon seeds. The experimental results show that the seeding device can finish the planting of whole tray at one time and throw seeds accurately; the rate of seed suction can be over 97% when the distance is 0. 5—1. 0 mm between suction nozzle and seeds,which can satisfy the demand of precision seeding in the tray.
