Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a nursery box for vegetable seedlings.

(Prior art) Vegetable seedlings are planted in a field using a vegetable seedling planting machine, and therefore, in a seedling box shaped as shown in Fig. 1,
Vegetable seedlings are grown. Conventionally known Utility Model 1977-
Publication No. 14454 discloses a box for growing vegetable seedlings in which a large number of seedling growing holes are arranged in parallel, and the seedling growing holes have a rectangular planar shape and a tapered longitudinal shape.

(Problems to be solved by the invention) In the known method, the seedling raising hole is filled with soil to grow the seedlings, the whole seedling raising box is loaded into a planting machine, and the seedling raising box is extruded by an extrusion device and planted in the field. However, when pushing out vegetable seedlings, there were many landslides at the corners, which was a defect.

The present invention prevents landslides from occurring at the corners even when vegetable seedlings are pushed out.

(Means for Solving the Problem) The present invention provides a vegetable seedling growing box 2 in which a large number of seedling growing holes 1 are arranged in parallel, and the seedling growing holes 1 have a rectangular planar shape and a tapered longitudinal shape. With,
Its four corners 4 are formed into arcuate partition walls 7 whose diameter becomes larger toward the lower end 6 than at the upper end 5, and is used as a nursery box for vegetable seedlings.

(Example) An example of the present invention will be described with reference to the drawings.
These are seedling-growing holes, which are formed in a tapered shape with an inner diameter that becomes smaller toward the bottom as a whole, and are arranged in a desired number of rows vertically and horizontally. The seedling raising hole 1 is filled with soil to grow seedlings, the whole seedling raising box 2 is loaded into a planting machine, and extruded by an extrusion device to be planted in a field.

The shape of the seedling raising hole 1 for planting is a rectangular shape 3 in plan view, and four corners 4 at each corner.
is formed into an arcuate partition wall 7 whose diameter gradually increases from the upper end 5 to the lower end 6.

Therefore, when looking at the top corner of the soil portion, the vegetable seedling 8 is formed into a corner with a small diameter R1, but when looking at the bottom end, it is formed into a corner with a large diameter R2.

(Function) Since the present invention has the above-described configuration, when the extrusion device slightly pushes the lower end 6 side toward the upper end 5 side, the four corners 4 are smaller than the upper end 5. Because it is formed into an arcuate partition wall 7 whose diameter increases as it reaches , the draft angle is larger than those without it, and it is not only very easy to pull out, but also because the draft angle is large, there are no landslides. .

In addition, since the four corners 4 are made into arcuate partition walls 7 whose diameter becomes larger toward the lower end 6 compared to the upper end 5, the strength is increased and the wall can be formed thinner.

(Effects) As described above, vegetable seedlings are planted in a field by a vegetable seedling planting machine, and therefore, vegetable seedlings are grown in a seedling box having the shape shown in FIG. Japanese Utility Model Application Publication No. 55-14454 discloses a box for growing vegetable seedlings in which a large number of seedling growing holes are arranged side by side, and the seedling growing holes have a rectangular planar shape and a tapered longitudinal shape.

In the known method, seedlings are grown by filling the seedling hole with soil, loading the whole seedling box into a planting machine, extruding it with an extrusion device, and planting it in the field. When extruding vegetable seedlings, There were many landslides at the corners, and defects were seen in these areas.

However, in the present invention, in a vegetable seedling growing box 2 in which a large number of seedling growing holes 1 are arranged in parallel, the seedling growing holes 1 have a rectangular planar shape and a tapered vertical cross section, and the four corners 4 are formed at the upper end. Since this is a nursery box for vegetable seedlings formed in the arcuate partition wall 7 whose diameter becomes larger toward the lower end 6 than the section 5, the extrusion device slightly pushes the lower end 6 toward the upper end 5. When pressed, the four corners 4 are formed into arcuate bulkheads 7 whose diameters become larger toward the bottom end 6 compared to the top end 5, so the draft angle becomes larger than those without it, resulting in a very Not only is it easy to pull out, but there is no landslide due to the large draft slope, and the four corners 4 are made into arcuate partition walls 7 whose diameter becomes larger toward the lower end 6 compared to the upper end 5. Therefore, it has the effect of increasing strength and being able to be formed thinly.
