The present invention relates to a seedling transplanting machine. In the seedling transplanting machine which uses a supporting frame for supporting a powder and granular material discharge device that is provided with a scattering part scattering powder and granular material in the powder and granular material storing part to the seedling carrying part of seedling carrying platform on the seedling carrying platform, the constitution of existing structure becomes complicated as the existence of powder and granular material storing part and a left-and-right moving mechanism of scattering part. Furthermore the powder and granular material discharge device discharges to all seedling carrying parts of seedling carrying platform even the seedling transplanting machine with one part of strip sowings is stopped by partial clutches, and therefore the powder and granular material is wasted. The measure for settling the problem is that a plurality of scattering parts are installed in the full width area in the left-and-right direction of seedling carrying parts of seedling carrying platform with a plurality of strip sowing amounts. A motor which respectively drives the plurality of scattering parts is provided. A clutch which stops the driving of the seedling transplanting device which has part of strip sowings and is selected from the seedling transplanting device with multiple strip sowings is provided. Furthermore a controller which is linked with the action of switching-off state of clutch for stopping the motor of the scattering part that has part of strip sowings and is corresponding with the clutch is provided.
