〔effect〕

According to the present invention, sowing of stocks of empty nursery boxes into each nursery box and loading of the seeded nursery boxes onto the storage cart are fully automated, and labor for nursery work is significantly reduced. Also, because a stock conveyor is arranged on the floor and a large number of nursery box groups are stocked on the stock conveyor,
Does not require a vast site. Also, since a pusher is provided between the end of the stock conveyor and the descending lift, the seedling raising box group can be collectively transferred from the stock conveyor to the descending lift. Since the transfer is performed as a set, the efficiency is higher than that when transferred individually.

Further, since the trolley storage device stores the box without raising and lowering the trolley, the present invention has an excellent effect such that the trolley can be moved quickly after the storage is completed.
