Precise quantitative disseminator of mechanical rice planting tray

An accurate seeder suitable for the mechanical seedling-transplanting tray features that the slot channel, is made at both sides of rectangular frame, a connecting rod assemblage can slide in said slot channel, and the strip blades of strip blade-turning pin assemblage can be driven by the connecting rod assemblage sliding in slot channel to be turned by 0-90 deg. Its seeding method includes such steps as providing germinated seeds, adding them to a seedling tray, inclining the seedling tray by 45 deg., opening a movable barrier plate, removing excessive germinated seeds, triggering, and dropping the germinated seeds in the field.
