The original no-tillage seeding and straw covering synchronous straw proportion recycling machine for the original stubble field provides that the mechanical energy for cleaning straws before no-tillage seeding is utilized to recycle redundant straws, so that the straws slide along the guide plate, but the guide plate adopts the arc-shaped structural shape, so that the mechanical energy consumption of the straws is too large due to the sliding of the straws along the guide plate, a large amount of straws cannot reach the operation area of the conveying mechanism, and the straws are blocked.
