Abstract

(57) [Summary] [Purpose] The purpose is to form a good root pot in the plug of the nursery box. [Structure] In a seedling raising box 1 in which a large number of seedling-raising plugs 2 are arranged in parallel, a through hole 4 is formed in the bottom plate of the plug 2, and a convex portion 5 for supporting the plug is formed on the bottom surface of the plug 2. . [Effect] Since the bottom surface of the plug 2 is supported by the convex portion 5 and floats from the mounting surface, the through hole 4 is constantly in contact with air. Therefore, the roots of anaerobic plants escape from the air and stay in the plugs to grow, so that the roots do not project outside the plugs and a good root pot is formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nursery box used for growing vegetable and cereal seedlings.

[0002]

[Prior Art]

 In order to efficiently raise seedlings with a small amount of soil and a small area, raising seedlings in nursery boxes has become popular in recent years. A conventional nursery box has a structure in which a large number of plugs for raising seedlings are arranged in parallel and a through hole is provided in the bottom plate of each plug. When the above-mentioned conventional nursery box is placed on the floor, the bottom surface of the plug is in close contact with the floor, and it is difficult for the through hole provided in the bottom plate to come into contact with air.

[0003]

[Problems to be solved by the device]

 The seedlings grown in the nursery box are removed from each plug and replanted in the fields. Therefore, the roots of seedlings must be placed in each plug and grown so that a root pot with the roots sprinkled on the soil is formed. If the root extends out of the through hole of the plug, the root pot will not be formed and the root will be cut when the seedling is taken out from the plug.

By the way, since the roots of plants are anaerobic, if the above-mentioned conventional nursery box 11 is used directly on the floor 6, it is difficult for air to come into contact with the through holes of the bottom plate. It overhangs and inhibits the formation of a preferable root pot (see FIG. 4). Therefore, conventionally, by placing a concrete block or talc on the floor and placing a nursery box on it, a space is formed between the bottom of the plug and the floor surface, ensuring air circulation and ensuring To be formed.

[0005]

[Means for Solving the Problems]

 The seedling raising box of the present invention is one in which a large number of plugs for raising seedlings are arranged side by side and a through hole is provided in the bottom plate, and a convex portion for supporting the bottom surface of the plug is provided on the bottom surface of the plug. It is sufficient that the height of this convex portion is about 2 to 4 mm.

[0006]

[Action]

 In the seedling raising box of the present invention, the bottom plate of the plug is supported by being separated from the floor surface by the convex portion protruding from the bottom surface of the plug. Therefore, the air is constantly in contact with the through hole formed in the bottom plate of the plug, and the root grows in the plug and does not extend outside the plug.

【Example】

 FIG. 1 is a perspective view of the seedling raising box of the present invention viewed from the bottom side, FIG. 2 is a plan view, and FIG. 3 is a sectional view showing a state of use. The seedling raising box 1 is formed by molding a synthetic resin sheet, and a large number of plugs 2 for raising seedlings are formed. This plug 2 is in the shape of a pyramid that is rectangular in plan view and widens upward, and a through hole 4 is formed in the center of the bottom plate 3 of the plug 2. A plurality of convex portions 5 are formed on the bottom surface of the plug 2 so as to surround the through hole 4. The convex portion 5 is for supporting the bottom surface of the plug 2 by floating it, and has a height of 3 mm. The number and height of the convex portions 5 can be appropriately changed within a range in which the bottom surface of the plug can be floated and supported.

Next, the usage state will be described. Soil is put in the plug 2 of the seedling raising box 1, seeded, and then directly placed on the floor 6 of a greenhouse or the like. When placed directly on the floor in the conventional nursery box, the through-hole 4 was blocked by the floor surface and little air was touched (Fig. 4), but in the nursery box 1 of the present invention, the bottom surface of each plug 2 is convex. Since the portion 5 is provided so as to project, the bottom surface of the plug 2 is in a state of floating from the floor 6 by the height of the convex portion 5. Therefore, a gap 7 is formed between the through hole 4 and the floor 6, and the air freely flows through the gap 7. Therefore, the through hole 4 is constantly exposed to the air, and the anaerobic root 8 remains in the plug 2 and does not project outside from the through hole.

In this invention, since the convex portion 5 is provided on the bottom surface of each plug 2, even in a nursery box made of a synthetic resin sheet which is easily bent, all the plugs do not bend when placed. Is supported with its bottom floating from the floor. Of course, the material of the nursery box may be foamed resin.

In addition, in this embodiment, a plurality of protrusions 5 are formed on each plug 2, but if the protrusions can support the bottom surface of the plug 2 by floating it from the floor, its specific shape, The configuration does not matter. For example, in the case of a small plug, it may be sufficient to provide protrusions only at the four corners of the bottom surface of the plug. It is also conceivable to form ridges around the bottom surface of the plug 2 instead of the plurality of ridges. The shape of the plug 2 can be freely changed.

[0011]

[Effect of the device]

 According to this invention, since the convex portion is formed on the bottom surface of the plug having the through hole, even when the plug is directly placed on the floor, the bottom surface of the plug is floated from the floor by the height of the convex portion. . Therefore, since the through hole formed in the bottom plate of the plug is constantly exposed to the air, the roots of anaerobic plants will stay in the plug and grow in order to escape from the air, and the root will not overhang the outside of the plug. Absent. Therefore, a good root pot in which roots are wrapped around the soil is obtained. In addition, since the roots do not project outside, it is easy to remove the seedlings from the plug when transferring them after raising the seedlings, and the roots are not cut during the work.
