Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a plurality of concave grooves for retaining water, and a convex strip having drainage holes for discharging water sprinkled in areas other than the concave grooves during water supply. Regarding the seedling raising boxes arranged in an alternating manner, more specifically, the seedling mounting stand that is set in the rice transplanter (note: the seedlings are grown in the seedling raising box and become a single pine-like body, and this pine-like body is placed on it. This relates to a seedling box developed in conjunction with a seedling stand for seedlings.

A number of the above-mentioned seedling growing boxes have been known in the past, but all of these conventional ones are of a type in which concave grooves and convex strips with drainage holes are arranged alternately in a straight line. Ta. However, in such a conventional type, when taking out the pine-like bodies from the nursery box, cracks such as horizontal cracks and vertical cracks often occur, which means that the pine-like bodies are damaged. The seedlings may separate into multiple pieces, which not only requires a great deal of effort to place on the seedling stand, but also makes it difficult to properly plant the seedlings with a rice transplanter.

In addition, even if a single pine-shaped body is taken out from a seedling nursery box and placed on a seedling stand, the seedlings may be set in the rice transplanter at an angle when being planted by the rice transplanter. The stepwise lowering of the seedlings onto the platform may not be carried out properly, and as a result, irregularities in the feeding caused by a large number of seedling catchers have been observed.

Furthermore, most conventional seedling boxes are made of synthetic resin, which means that they can be manufactured in large quantities using molds, are lightweight and therefore easy to handle, reduce overall cost, and are durable due to their acid and alkali resistance. However, in order to reduce material costs, all of these were formed to be as thin as 2 mm thick. Therefore, it has been difficult to obtain sufficient strength.

Furthermore, Japanese Patent Publication No. 51-3645 describes a ``seedling growing pine characterized by having continuous pyramid-shaped or hemispherical recesses in the sheet and holes on the ridge lines between the recesses.''
has been proposed, but in this method, the underside of the grown pine-shaped body has convex stripes that are continuous in the front, back, left, right, and diagonal directions, and therefore, it lacks the ability to gradually lower the seedlings on the seedling stand as described above. It is.

The present invention was developed in order to eliminate the disadvantages of the conventional methods as described above, and the purpose of the present invention is to enable the growth of a strong pine-like body.
To provide a seedling raising box which does not cause cracks in the horizontal and vertical directions when the pine-like body is taken out from the seedling raising box or placed on a seedling stand.

Another object of the present invention is to provide a seedling raising box in which the seedling tray, which is set at an angle in a rice transplanter, can be lowered step by step without any trouble, thereby allowing good catching by a seedling catcher. .

Another object of the present invention is to provide a nursery box that can be made thin and strong.

Still another object of the present invention is to provide a seedling raising box that can prevent the white roots from being cut as much as possible during feeding with a seedling catcher.

Next, embodiments of the present invention that can achieve the above objects will be described in detail with reference to the accompanying drawings.

[First embodiment] Figure 1 is a conceptual plan view, Figures 2 to 4 are the same as above.
In the cross-sectional view along the line, a is a box body having a bottom plate _A1 and a peripheral edge _A2 configured to allow drainage, and x is a pine-like body grown in the box body A, which is set diagonally in a rice transplanter. y is the direction that will be the top when placed on the seedling stand, b is the direction that will be the top at the center in the left and right direction of the box body a, and the direction x is the bottom when placed on the left and right of the center. direction y
, a number of diagonal protrusions are connected via the upward connecting portion _b1 and the downward connecting portion _b2 , and c indicates the numerous diagonal grooves formed between the diagonal protrusions b. However, the upward connecting portion b ₁ is omitted at the portion where the diagonal protruding strip b comes into contact with the peripheral edge a ₂ constituting the box body a. Note that a large number of drainage holes 1 having a desired shape (square, round, etc.) are bored in the diagonal protrusion b.

The diagonal protrusions b and the diagonal grooves c are constructed as shown in FIGS. 2 to 4, for example. That is, in FIG. 2, the diagonal protrusion b and the diagonal groove c are composed of the gently sloped plate part 2 and the steeply sloped plate part 3, and the diagonal groove c is composed of the gently sloped plate part 2 and the steeply sloped plate part 3. Narrow plate portion 4 between inclined plate portions 3
In FIG. 3, it is composed of a gently inclined plate part 2 and a steeply inclined plate part 3, and in FIG. 4, it is composed of a gently inclined plate part 2 and a vertical plate part 5.

[Second Embodiment] Fig. 5 is a conceptual plan view, and Fig. 6 is a sectional view taken along the same line as above, where a is the box body, _a2 is the periphery, and b is a diagonal convex strip having numerous drainage holes 1. , c indicates a diagonal groove, d indicates a plurality of straight protrusions having a large number of drainage holes 6, and the straight protrusion d is in the first embodiment.
At a location corresponding to each upward connecting portion b ₁ and each downward connecting portion b ₂ , the direction x that is the upper part,
Connecting plate portions 7, which are connected in the lower part direction y and configured in a series, and which also serve as the configuration of straight protrusions d and diagonal grooves c, are evenly inclined outward to the left and right as shown in Fig. 6. has been done.

The preferred configuration of the present invention has been described above using two embodiments, but the left and right shapes of the diagonal protrusions b, straight protrusions d, and diagonal grooves c may be modified as appropriate. be.

In the configuration described above, a desired amount of culture soil and seedlings are placed in the box body a, and the seedlings are grown into a pine-like shape in the same manner as a conventional seedling-raising box.According to the present invention, the following Effects can be obtained.

(i) At the center in the left and right direction of the box body a, the upper direction x is connected via the upward connecting part b ₁ , and the lower part y is connected to the downward connecting part on the left and right of the center part. By constructing the seedlings through a large number of diagonal protrusions b and diagonal grooves c connected through b ₂ , it is possible to grow a strong pine-like body, and therefore, this pine-like body can be easily removed from the seedling growing box. , it is possible to eliminate the occurrence of cracks in the horizontal and vertical directions when placing the seedlings on the table.

(ii) With the above configuration, the seedling platform set on the rice transplanter at an angle can be lowered step by step without any trouble, and the seedling catcher can perform good catching.

(iii) Although the structure described above can be made thin and strong, it can be made even stronger by providing the straight protrusions d.

(iv) It is possible to prevent the white root from being cut as much as possible during catching with a seedling catcher.
