DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising system in which a seedling box in which rice seedlings are planted is provided, and a seedling raising pool is provided on the ground for feeding and draining water to grow seedlings and a method of constructing the same. .

[0002]

2. Description of the Related Art As shown in FIG. 14, conventionally, a seedling raising pool P has a frame 1 formed of embankment or square material on all sides of a region where the seedling raising pool P is installed, and a seedling raising pool P is formed from above the frame 1. The vinyl sheet 2 is laid on the entire surface of the area where the is installed, and the vinyl sheet 2 is formed by fixing the vinyl sheet 2 with soil or stone 3 or the like outside the frame. When the seedling raising pool P is formed, the area where the seedling raising pool P is to be set is preliminarily subjected to the work of leveling the ground surface. In the leveling work, for example, the surface soil is plowed and softened, and horizontal threads are stretched at four corners of an area to be used as a pool. Also, the seedling raising box B is placed in the water tank of the formed seedling raising pool P.
When arranging the seedling raising pool P, a crossing plate communicating with the inside and outside of the seedling raising pool P is provided, and a unicycle or the like loaded with the seedling raising box B is manually operated to transport the seedling raising box B into the seedling raising pool P.

[0003]

In the conventional seedling raising pool P, since the seedling raising pool P is installed directly on the ground, the water supplied to the seedling raising pool P is drained from the vinyl laid on the frame 1. The sheet 2 is unfolded, and is simply performed by the potential energy of the difference between the height of the drain and the drain. Therefore, there is a problem that the seedling pool P installed directly on the ground has low potential energy and poor drainage ability. Furthermore, since the drainage is performed directly on the same surface as the installation surface of the seedling raising pool P, the installation surface of the seedling raising pool P is soaked with water every time the drainage is performed, and the ground is softened. There is a problem of lowering. There is a problem that the softening of the ground also has an adverse effect on the workability (such as laying over sheets) of the nursery pool P. Further, in the case of forming the conventional seedling raising pool P, it has been necessary to manually level the installation surface of the seedling raising pool P by hand in order to level the installation surface. This work is carried out by plowing the installation surface to some extent, leveling the ground surface with a tip of a board or the like, and solidifying it by stepping on the ground, and has a problem that it is very complicated. When the seedling raising box B is transported into the seedling raising pool P, the unicycle loaded with the seedling raising box B is manually moved into the water tank via the handover plate, and the seedling raising box B is manually placed in the water tank. There is a problem that the efficiency of the arrangement is poor. In addition, there is a problem that unevenness is formed on the installation surface, which is the bottom surface of the water tank, due to the load of the unicycle, and the installation stability of the nursery box B in the water tank is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has improved drainage efficiency, improved workability associated with drainage efficiency, and stable installation of a nursery pool. An object of the present invention is to provide a seedling raising system capable of improving the arrangement efficiency of the seedling raising boxes and the stability of the placement of the seedling raising boxes, and a method of constructing the same.
