Vacuum suction seeding-machine can increase operating speed, and that save seeds. The critical air flow velocity has been known by analysis in this article ,in addition, suction nozzle fluid field has been simulated in 5kPa,10kPa,20kPa,30kPa,40kPa vacuum case, we obtain that the results of adsorption distance are 3mm, 4mm, 5.5 mm,7mm,12mm.The final adsorption distance is bigger when vacuum become big.
