[Industrial application]

 The present invention relates to a nursery box for rice seedlings, and more particularly to a nursery box capable of reducing root cutting work when transferring finished seedlings to a seedling stand of a rice transplanter.

[0002]

[Prior art]

 The seedling raising box currently used is shown in FIG. A conventional nursery box is made of plastic, and when the seedlings have grown to some extent, the medium and the soil are taken out from the nursery box and placed on a machine to be planted. The width 2 has an inner size of 580 mm, the lateral width 3 of the short piece has an inner size of 280 mm, and the height 4 has a standard size of 30 mm. About 1000 to 1500 openings corresponding to 5 to 16% are provided. The size of the hole is 5 to 6 mmΦ, and a molding medium or cultivating soil is used as a bed soil to fill the hole with a height of about 20 mm. When transferring the completed seedlings to the seedling stand of the rice transplanter, the roots are growing in the openings at the bottom of the nursery box, so the soil is turned upward, and the root cutting board of Fig. 6 is placed on the frame board. It is inserted from the 5 side that is not attached, root-cut, and the finished seedlings are placed on the root-cutting board and transferred to the seedling stand of the rice transplanter. By the way, when raising rice seedlings, they are divided into those for milk seedlings, seedlings, and middle seedlings depending on the number of days required from the time of planting.

For example, as a general seedling raising method, a seedling raising box is filled with a molding mat made of rock wool or a pulp / urinary foamed resin or cultivating soil as floor soil, watered, and then seeded rice Seeds, cover with 1.0 to 1.3 kg / box of soil, heat at 32 ° C for 2 days, germinate, and then green for 5 days, watering once during that time As a result, it can be transplanted to Honda by a rice transplanter. In the case of young seedlings, the seedlings are grown for an additional 2 weeks, and for medium seedlings, the seedlings are grown for an additional 3 weeks, and then transplanted to Honda as a completed seedling by a rice transplanter. When all of these completed seedlings are transferred to the seedling stand of the rice transplanter, the roots are growing from the opening at the bottom of the conventional nursery box to the outside, so the soil is turned upward and from that time, After root cutting with a root cutting board etc. in advance, seedlings are put on the root cutting board and transferred to a seedling stand of a rice transplanter.

[Problems to be solved by the device]

 In recent years, farmers are leaving primary industries for young people, shortages of successors, aging, and labor shortages have led to demand for labor-saving labor for raising seedlings. Currently, when transferring finished seedlings to rice transplanters, roots extend from the openings at the bottom of the nursery box to the outside, and price cutting work is done with a root cutting plate, etc. Labor is necessary to move to. Since roots are entangled and grow in the nursery, root cutting requires a considerable amount of work. In addition, since there are many holes at the bottom of the nursery box, root growth is promoted, which causes further labor, which is a heavy burden for aging farmers, and a solution to this has been desired.

[0005]

[Means for Solving the Problems]

 The present invention provides a nursery box that reduces the work of root cutting, and is particularly suitable for seedlings that are completed 7-8 days after sowing. That is, the present invention is a seedling raising box which is made of a plastic such as polypropylene as a material and is formed into a box shape and can store a forming medium or a forming medium, and at least one side wall frame on the short side of the box is removed. It is a nursery box. The details will be described below. The material of the nursery box is plastic such as polypropylene. Moreover, the inner dimensions of the nursery box are integrally molded with a standard size of 30 mm x 280 mm x 580 mm. This is a nursery box in which at least one side wall frame on the short side of the box is removed. In addition, the seedling raising box is formed by projecting plate-like legs from the bottoms of both short sides of the box, and it is desirable that the length of the legs is about half of the side wall. Inside the nursery box, a molding mat or rock soil made of rock wool or pulp / urea foam resin can be stored.

Further, since the present invention is intended for a nursery box for growing finished seedlings about 7 to 8 days after sowing, the porosity of the bottom part is 1% or less of the total area of the bottom part, preferably 0. The amount of holes was reduced to 1% or less, and the number of holes at the bottom was reduced, and the size of the holes was reduced to around 3 mmΦ. Further, it is desirable to provide 3 to 4 openings in the long side wall near the boundary with the bottom so as to have a water draining effect. In addition, if necessary, several grooves that do not penetrate in the longitudinal direction of the bottom part shall be provided up to the end of the bottom part where the short piece frame has been removed, so that the structure under the gap under the molding mat provides a drainage effect. You can also Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0007]

【Example】

 An embodiment of the present invention is shown in FIG. 1, FIG. 2 or FIG. In either case, the side wall that constitutes one piece of the box, in the figure, the side wall on one side of the short piece is removed, and the foot that protrudes from the bottom of the box below to approximately half of the side wall to the same length. It has a structure with 7. There is a slight taper from both short piece frames to the legs so that a large number of nursery boxes can be stacked as shown in FIG. In the stacked state, the foot 7 protruding from the bottom of the box closes the soil covering part of the removed side wall of the nursery box below it, so that the soil cannot be spilled to the side. The target is a nursery box for growing seedlings that are about 7 to 8 days after sowing, so after the seedling boxes are sprouting in a stacked state, even if the cover soil spills a little, it is sufficient to leave it flat and complete as a seedling. To be made. In the bottom 6 of FIG. 1, 3 mmΦ × 15 holes are evenly formed. The bottom 16 in FIG. 2 has no holes, and water drainage openings are provided near the boundaries between the bottoms of the long sidewalls on both sides. This is a nursery box having a structure in which several grooves which do not penetrate the longitudinal direction of the bottom 26 of FIG. 3 are provided up to the end of the removed bottom part, and the effect of draining water from the gap formed by the groove under the molding mat is provided. All of these are examples of the present invention. The nursery bed is filled with a molding mat (18 mm x 280 mm x 580 mm) made of rock wool or pulp / urea foam resin. The completed seedlings can be directly pulled out from the removed frame side by hand and transferred to the seedling stand of the rice transplanter. Significant labor savings, which was not possible with conventional nursery boxes, can be achieved.

[0008]

[Effect of the device]

 In the present invention, since at least one side wall frame on the short side of the nursery box inside is removed, it is not necessary to turn the bed soil upward even when using the root cutting plate, and it can be directly placed under the forming medium or culture medium. You can insert a root cutting board. Further, since the plate-shaped foot portion is provided, it is possible to prevent the soil from spilling from the side by stacking a large number of seedling raising boxes and closing the soil covering portion of the removed side wall portion. Furthermore, since the short piece frame in the box was removed, even when transferring the completed seedlings to the seedling table of the rice transplanter, the completed seedlings should be transferred directly from the seedling raising box to the rice transplanter without carrying them on the root cutting board etc. Can be done. In addition, since it is a nursery box that grows the completed seedlings about one week after sowing, the roots do not grow so much, so the porosity of the bottom is 1% or less of the total area of the bottom, preferably 0.1% or less. The number of holes at the bottom can be reduced and the size of the holes can be reduced to 3mmΦ. Alternatively, 3 to 4 openings are provided in the long side wall near the boundary with the bottom, or several non-penetrating grooves are provided in the longitudinal direction of the bottom to provide a drainage effect. The roots do not enter the part, and the completed seedlings can be transferred directly to the rice transplanter without root cutting work. Therefore, even a farmer who is suffering from labor shortage or aging can easily transfer the completed seedlings to the seedlings of the rice transplanter and transplant them to Honda, thus saving labor.
