Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising container for raising seedlings of plants until they are transplanted to a growing place.

[0002]

2. Description of the Related Art When growing seedlings of flowers and trees, from the seeding stage until it can be transplanted to the growing area in earnest, soft resin seedling containers called pots, paper, etc. It was generally grown in a corrosive container. These are cheap, but the container becomes a waste and there is a problem in processing.

In such a pot or container, the root grows as the plant grows, and if no measures are taken, the root grows while rotating along the inner surface of the peripheral wall of the container and the peripheral edge of the bottom, a phenomenon called "looping". Begins. As a result, the following problems occur in the living state and the growing state after transplantation. (1) It takes time for the seedlings that have undergone this looping to take root after transplantation, which causes seedling collapse. (2) As a result of looping, the entangled roots damage each other, causing root rot and death due to invasion of various bacteria into the roots. (3) Since only some roots grow long, it is difficult for more roots to root. (4) Since the roots crawl in a pot or a container in a complicated manner, seedlings are less likely to come off during transplantation. (5) Since the roots are intricately entangled with each other to form a container, water accumulates in the lower part, which causes root rot.

Therefore, in order to solve the above problems and grow an ideal seedling, it is desirable to place it under the following conditions. (1) Take measures to prevent roots from crawling so as not to cause looping. (2) Stop root growth at the bottom of the container so that as many new roots as possible are rooted. (3) Eliminate the water pool at the bottom of the container and always clean the nursery bed with fresh water.

[0005]

The present invention has been made to solve the above problems and prevents rooted roots from growing unnecessarily, and more roots are rooted. It is an object of the present invention to provide a container for raising seedlings that can maintain a desired medium condition for rooting.

[0006]

The present invention is a seedling raising container which is formed of a hollow side wall in a substantially vertical direction, wherein a convex strip is formed on the inner surface of the side wall from the bottom to the top thereof, and the bottom face of the seedling raising container is formed. Is an open part.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The container for raising seedlings of the present invention is not limited to a cylinder or a square tube, but is a tube having a side wall, and an open portion is formed in a portion corresponding to the bottom surface of the lower end. is there. A plurality of ridges extending from the lower end to the apex are formed on the inner side of the side wall so as to prevent the growth of roots extending in the circumferential direction. In particular,
Since this ridge is formed so that its cross section has a corner, the tip of the root cannot go over this corner and descends vertically along the ridge. The reason why the ridge extends from the lower end to the top is that when the ridge is cut off at any of the soil-filled portions, the root starts looping from there.

Most of the lower end of the container is open, and only a slight frame is formed so that the medium does not drop. Therefore, since the roots that have grown downward come into contact with air at this lower end, they do not grow further downward.

As a result, the seedling-growing plant newly develops roots necessary for further growth. Therefore, unlike the conventional container that allows looping, short roots form a state in which they grow radially and innumerably. Therefore, the entanglement phenomenon of the root, which has been a problem above, is eliminated, and it is possible to prevent the root from being damaged and the propagation of various bacteria. Furthermore, since the roots are not looped, the roots immediately extend radially after transplanting and the rooting is very fast,
There is no need to worry about seedlings falling down.

In addition to preventing excessive water retention due to the entanglement of the roots, in the present invention, a draining means such as a string is hung from the lower end of the container so that the soil can be kept cleaner. It was made possible to abundantly perform fresh irrigation. As a result, the health condition of the seedlings is dramatically improved, and thus good growth of the seedlings, which is not apparently obtained, can be obtained.

The seedling raising container of the present invention can be used alone, but in order to improve the efficiency of seedling raising work, a plurality of containers can be connected and used as a container. When connecting as a container, it is possible to integrally form adjacent containers by an upper plate formed so as to project to the top of the container.

Thus, in the container formed as described above, in order to improve the drainage of the irrigation water to the individual containers, the upper surface of the upper plate is gentle around the respective containers so that the inside thereof becomes low. It is desirable that an inclined surface is formed.

EXAMPLE FIG. 1 is a partially cutaway perspective view showing the form of an individual seedling raising container of this example, and FIG. 2 is a perspective view showing an example of the case where a container is formed.

As shown in FIG. 1, a nursery container 1 of this embodiment.
Is a cylindrical shape (reverse frusto-conical shape) whose bottom is slightly narrowed, and a plurality of ridges 11 extending from the lower end to the upper end of the seedling raising container 1 are formed on the inner surface of the outer wall in a substantially vertical direction. The ridge 11 is in the shape of a quadrangle whose cross-section is clearly formed.

A frame 13 capable of holding a culture medium is formed on the bottom surface of the lower end portion, which is the open portion 12. From the frame 13, a drain string 14 knitted on a rope is attached and arranged so as to hang down.

When carrying out seedling raising in the seedling raising container 1, a medium that can be held by the frame 13 is put into the seedling raising container 1 so that the inside of the seedling raising container 1 is not shielded from the outside air, and seeding or cuttings or seedlings are planted. As the seedling grows, its root eventually reaches the open portion 12 at the lower end and stops its growth, and the seedling promotes new rooting.

In the lower part of the seedling raising container 1, excess water remains due to the water retaining capacity of the medium, but this residual water is absorbed and eliminated by the suction effect generated by the cohesive force of the water in the drainage string 14. Therefore, the lower part of the seedling raising container can be maintained in a clean state even when continuous fresh irrigation is continued, and a very healthy seedling can be grown.

The seedling-growing container 1 of this embodiment can be held by a dedicated holder or the like to keep the drain string 14 in a suspended state, but as an efficient means for carrying out a large number of seedlings at the same time. Is preferably in the form of a container 2 as shown in FIG.

The container 2 is formed by integrally forming a plurality of seedling raising containers 10 with an upper plate 21 connecting the upper end portions thereof. Although the individual seedling-growing containers 10 are of the form described above, they are surrounded by an inclined surface 20 formed around the upper end of the seedling-growing container 10 so as to gradually lower toward the respective seedling-growing containers 10.

Therefore, when the entire container 2 is watered from above, the water does not remain on the upper surface of the upper plate 21 of the container 2 and flows evenly into the respective seedling raising containers 10.

[0021]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the following effects can be obtained by completely preventing rooting of the roots in the seedling raising container. (1) New rooting is promoted, and strong seedlings with very many roots can be grown. (2) There is no entanglement between roots, the roots do not hurt, and diseases and the propagation of bacteria can be prevented. (3) There is no excess water remaining at the lower end of the container, and root rot can be prevented.
