Seedlings fallen above the horizontal belt are inserted into the vertical belt by the movement of the belt, and the seedlings sandwiched between the vertical belts are inserted into the planting disc and implanted into the ground at regular intervals.

However, when the seedlings are sown by using an onion planter having such a technical configuration, the seedlings transferred by the fingers do not have a separate alignment device at the top of the belt. It is introduced into the state so that the seeding is not uniform. In addition, the matted seedlings do not stand vertically from the ground, and the seedlings do not have a deep seeding depth, so a lot of seedlings are placed on the soil.

In addition, due to the planting disc, the problem that can not be sown in the soil to apply vinyl mulching occurs, so that problems such as applying mulching and sowing holes in the mulching after planting, and re-set the seedlings using manpower.

The present invention relates to an onion transplant method and apparatus.

The method used in the conventional planter was implanted by a planting disc, and the implanted method was invented to solve the problem of reworking using manpower because the depth of seedlings became shallow, and the conventional method was vinyl. It was configured to solve the problems that could not be used for mulching, so that the seeding method can be taken at regular intervals by the transplant blade and the seedlings are dropped so that the seeding work can be performed more accurately than the conventional seeding method. It is possible to reduce the production of high quality crops.
