Conventionally, there was a technique (for example, Japanese Utility Model Application Publication No. 130128/1983) in which spare seedlings were inserted into the sloping upper end of the auxiliary seedling stand and taken out from the slanted lower end of the stand. Since we had fixed the
It is necessary to lift and take out the spare seedlings, and there is also the disadvantage that mud accumulates in the seedling stopper part.

In addition, there is a technology (for example, Japanese Utility Model Application Publication No. 53-32124) that provides a seedling stopper that can be opened and closed at the seedling entry/exit portion of the reserve seedling stand, but the seedling stopper must be opened and closed manually each time the reserve seedlings are taken in and out. The stopper operation is troublesome, there is a risk of erroneous operation such as forgetting to put it on, the handling operation is inconvenient, and it is difficult to smoothly succeed multiple rows of seedlings.

The present invention solves the above-mentioned conventional drawbacks, and uses a spring to erect a seedling stopper provided at the lower end of the slope of the stand for seedlings so that it can freely fall down at the upper end of the slope by the force of inserting the seedlings. At the same time, the seedling stopper is brought into contact with the outer frame of the seedling stand to restrict the tilting of the stopper toward the lower end of the slope, and the seedling stopper is opened by the operation of inserting the preliminary seedling. and can be moved closed,
Compared to the conventional model, it eliminates the need to lift up spare seedlings when taking them out, and eliminates the trouble of manually opening and closing the seedling stopper when taking out and putting in spare seedlings, and has a simple structure that allows the operation of putting in and out of spare seedlings to be extremely functional.
