DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for raising seedlings for growing fruit seedlings, leafy seedlings, flowers, trees, and the like.

[0002]

2. Description of the Related Art Generally, when raising these plants, seedlings for raising seedlings are put into small-diameter pots, and seedlings or seedlings of fruits and vegetables are planted for raising seedlings, planted or sold, and generally called polypots. Seedlings are put into synthetic resin pots, and seedlings are planted in the pots. Plants grown in plastic pots are sold as they are in the plastic pots, or removed from the pots and planted.

[0003]

The fruit seedlings, leafy seedlings, flowers and trees grown in the small-diameter pots and polypots as described above were taken out of the small-diameter pots and polypots and planted around during planting. The roots are cut and planted. However, in these types of plants, not only does it take time to cut off the roots that are rooted when they are taken out from a pot or a polypot at the time of planting, but also, as described later, especially in those raised in a polypot, the roots do not go out of the polypot, and the main roots are raised during seedling. Therefore, there is a problem that the growth after planting is poor and the rooting of the fruit seedlings is apt to occur.

[0004] When a seedling is raised in a polypot, there is no air permeability and moisture evaporated from the soil in the polypot condenses on the inner wall of the polypot. There is also a problem that the roots of the tree cannot extend outward from the polypot, extend along the inner wall of the polypot, and cause so-called main root roots, thereby reducing the number of fine roots. At the time of planting, the rooted portion is removed and then planted, so that fruit and vegetable seedlings, leafy seedlings, flowers and trees do not grow well, and poor rooting tends to occur.

[0005] A conventional polypot for raising seedlings used for raising seedlings is, for example, a synthetic resin melted and formed into a pot-like shape. The pot from which the fruit seedlings, leaf seedlings, flowers and trees are taken out is They have to be collected and disposed of as industrial waste, which is troublesome to collect and requires transportation and incineration costs.When incinerated, toxic substances such as dioxin are generated. There is a problem of causing pollution. Therefore, prior to the present invention, the present inventor forms a pot with a sheet made of a corrosive or biodegradable sheet such as linen or a biodegradable plastic fiber, and places the pot in the pot storage portion of the pot case. It is proposed that the pot be stored, sowed or raised in this pot, and sold or transplanted with the pot at the time of sale or transplantation.

[0006] However, it is difficult to sow seeds in pots according to the prior proposals or to match the growth time of the plant to be raised and the time of corrosion or biodegradation, and the effect cannot be sufficiently exerted. there were. In particular, even in the same plant, the growth of the root of the plant is greatly changed by various conditions such as sunshine, irrigation, and temperature, and the above-mentioned problem becomes more remarkable when the type is changed. The present invention has been proposed in view of the above-described problems, and aims to provide a seedling raising device that can prevent root circumference of a main root and can produce fruit seedlings, leafy seedlings, flowers, and trees with a large number of fine roots at low cost. Is what you do.

[0007]

In order to achieve the above object, a seedling raising apparatus according to the present invention comprises a seedling raising space formed by a side wall portion having a tapered surface having a large diameter at an upper opening portion and a bottom portion. Is formed in a case, and a vent is formed in a side wall portion and / or a bottom surface portion of the pot. In addition, the ventilation part is formed by a slit and / or a mesh extending in a vertical direction, and a gap between the slits is set within a range of 1 mm to 3 mm, or a ventilation hole is provided between the bottom surface of the pot and the installation surface of the case. It is also characterized by forming a space.

[0008] The seedling raising method according to the present invention comprises a side wall portion having a slit having a mesh and / or gap set within a range of 1 mm to 3 mm, a tapered surface having a large diameter at an upper end opening, and a bottom surface. A plant that is formed with a part and raises plants in a nursery space, thereby maintaining air permeability and ventilation / water permeability with a mesh and / or slit, preventing the plant from turning around in the pot, and having more fine roots than the main root And raising the seedlings so that no roots are outside the pot.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a nursery apparatus and a nursery method according to the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the seedling raising device, and reference numeral 1 in the figure indicates the entire seedling raising device. The seedling raising device 1 includes a plurality of pots 3.
.. Are formed. Each of the pots 3 is formed of a side wall portion 5 formed on a tapered surface having a large diameter at an upper opening portion 3a and provided with a slit (venting portion) 4 and a bottom portion 6, and has a space for seedling raising therein. 7 are formed (see FIGS. 2 and 3).

As shown in FIGS. 2 to 4, the bottom portion 6 is provided with a grid-like plate member 8 disposed at an intermediate height position of the side wall portion 5 formed on the tapered surface, and a lower portion thereof is provided with a bottom plate receiving projection 9
And the upper part is pressed by the bottom plate pressing projection 10. In this example, the space 11 is formed by opening the height position of the grid-like plate member 8 by 5 cm from the bottom of the case 2 (the installation surface of the case 2).
It can be set arbitrarily within a range of 10 cm. If this is less than 2 cm, the space 1 at the bottom of the pot 4
This is due to the fact that the number of 1s is small and equal to the absence of an air layer, and that 10 cm is bulky as a whole, which is not practically desirable.

The slit 4 provided in the side wall portion 5
Are formed at substantially equal intervals between the upper end opening 3a of the side wall portion 5 or the vicinity thereof and the grid-like plate member 8, and the gap W of the slit 4 is 1 Although the gap between the slits 4 is 0.5 mm and the gap between the slits 4 is 3 mm, the gap between the slits 4 may be in a range of 2 mm to 15 mm.
The gap W of the slit 4 can be set arbitrarily within a range of 1 mm to 3 mm. That is, when the gap is less than 1 mm, not only is it difficult to mold, but also the clogging is blocked and air permeability and water permeability are provided. Conversely, when the gap exceeds 3 mm, the cultivation soil 13 leaks together with irrigation. This is because it becomes easy to do.

A hole 12 for inserting a push-up rod (not shown) is formed in a central portion of the lattice-shaped plate member 8 forming the bottom surface portion 6 when the plant grown in the seedling raising space 7 is taken out of the pot 3. (See FIG. 4). In addition, pot 3
During use, a linen cloth or a cloth made of biodegradable plastic fiber is provided in the holes 12 to prevent the cultivation soil 13 from leaking. The mesh of the grid plate 8 is 1.5 mm, but the mesh of the grid 8 may be arbitrarily set within a range of 1 mm or more to 3 mm or less for the same reason as described above. Can be set.

Next, the steps from the cultivation of a plant to planting using the seedling raising apparatus 1 constructed as described above will be described. FIG.
As shown in (1), the potted soil 13 is filled into the tapered pot 3 which is narrowed down, and seeds of, for example, fruit seedlings are sown in the soil 13 or plant seedlings are planted and irrigated to grow seedlings. At this time, the pot 3 is located below the bottom portion 6 of the space 1.
Due to the formation of 1, excess water that has been irrigated does not flow outward from the slit 4 and the bottom surface portion 6 formed around the pot 3, and does not accumulate in the pot 3 or form dew.

As a result, so-called "root circumference" in which the roots of the fruit and vegetable seedlings 15 grown along the peripheral wall of the pot 3 do not occur, and the number of fine roots is larger than that of the main roots. In addition, since the space 11 is formed below the bottom portion 6, the fruit seedlings 15
No longer extends downward from the bottom portion 6 of the pot 3. Then, as shown in FIG. 5, when the fruit seedlings 15 have grown to a predetermined size and are to be transplanted, the seedlings 15 are transported to the desired place to be transplanted while being kept in the pot 3. .

After being transported to a desired place, the pot 3 containing the fruit seedlings 15 is inserted into a hole 12 formed in the center portion of the lattice-shaped plate 8 on the bottom portion 6 of the pot 3 by inserting a stick from below the seedling to raise the seedling. The plant cultivated in the working space 7 is pushed up from the pot 3 and taken out. Thus, the cultivation soil is exposed around the root portion of the fruit and vegetable seedlings 15 removed from the pot 3 (see FIG. 6). Therefore, when the vegetable seedlings 15 are planted at a desired place in this state, the roots of the fruit vegetable seedlings 15 are stretched without stress, the roots of the fruit vegetable seedlings 15 are stretched without stress, the roots are good after transplantation, and the roots are deep. Invading, so the vigor is strong. By the way, the plants raised by the seedling raising device of the present invention do not have roots in the pot 3 of the main root, and the fine roots are 3 to 4 times higher than those in the conventional polypots than the main root, and the roots are good. Was confirmed.

In the above-described embodiment, the space 11 is formed below the bottom portion 6 of the pot 3. However, the present invention is not limited to this, and as shown in FIGS. The shape may be such that there is no space below the part 6. In this case, as shown in FIG. 9, when the case 2 is received by the tray 17 having the projections 16, 16,... Formed higher than the depth of the pot 3, the space 11 can be formed below the pot 3. It is. Also, the material forming the case 2 may be a synthetic resin made of biodegradable plastic. In this case, the case 2 can be crushed and buried, eliminating the need for collection and incineration. It is.

Further, in the above embodiment, the ventilation portion is formed by slits. However, the ventilation portion is formed by providing many small holes in the side wall portion, or the ventilation portion is formed by meshing the side wall portion. You can also. In this case, it is a matter of course that the size of the small holes and meshes is set to a size that does not allow the cultivation soil to leak out. In addition, although a large number of pots 3 are formed in the case 2 in the above embodiment, it is needless to say that only one pot can be provided as shown in FIG.

[0018]

According to the present invention, a seedling raising space formed by a side wall portion having a tapered surface having a large diameter at an upper end opening portion and a bottom surface portion having a ventilation portion for preventing cultivation soil from leaking. By raising the seedlings in the plant, air permeability and water permeability can be ensured in this ventilation part. Also, the survival of the fruit seedlings is much better.

It is possible to prevent the roots of the plant in the pot and thereby increase the number of fine roots compared to the main root, and when transplanting the plant, plant the plant as it is with the cultivation soil exposed around the root of the plant. As such, the use of a conventional polypot can be omitted. Therefore,
In addition to eliminating the trouble of taking out and transplanting from a plastic pot as in the past, transplanting can be done in a short time and easily, as well as eliminating the trouble of collecting the removed polypot and treating the polypot as industrial waste. There is also an advantage that problems such as various problems, such as trouble and cost of transportation and incineration, and problems such as generation of dioxin pollution at the time of incineration can be eliminated.

Further, since the plant is cultivated by directly cultivating soil in the pot, the decomposition time and the period of the plant are higher than those in which the plant is cultivated using a pot formed of biodegradable plastic or the like. There is an advantage that the plant can be easily cultivated without having to match the growth of the plant.
