Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling pot suitable for growing seedlings of plants such as flowers, vegetables and trees.

[0002]

2. Description of the Related Art FIG. 1 shows an example of a seedling raising pot that has been most popularly used in the past. A is an elevation view, B is a sectional view,
C indicates a use state. In the figure, a pot 1 is an inverted trapezoidal thin container having a bottom 2 and a relatively large hole 3 for draining water is formed in the center of the bottom. Conventional pots are made of plastic such as thin vinyl, and are mass-produced from one wide sheet by molding or the like. Most of the materials are made of plastic and are made of water-impermeable materials.

[0003] The culture soil 4 is put into this pot, and seeds are directly sown or plant seedlings are planted and grown as shown in Fig. 1C. In the figure, 4 is a seedling such as a flower, and 5 is a soil. Seedlings grown in such pots are widely used because they are easy to carry, and seedlings are sold for each pot, which is convenient for handling products.

[0004]

However, although pots are suitable for management and sales, after purchase, the flowers in them,
When replanting vegetables, seedlings, etc. in flower beds or fields, the seedlings must be removed one by one from this pot. This isn't much of a problem when planting one or two seedlings, but it can be a very daunting task when planting tens of thousands of flowers in flower beds or flower parks or planting lots of vegetables in large fields.
Personnel are needed to remove the seedlings from the pot.
In addition, it is troublesome to clear the pot after taking it out, it is often blown away by the wind, and the work efficiency is further reduced.

[0005] Further, as shown in FIG. 1C, the roots of the seedlings with a little momentum and the seedlings that have been aged a little often protrude from the drainage holes 3, making it more troublesome to take out the seedlings. On the other hand, if the root pot is not sufficiently formed, the pot is broken when the seedling is removed from the pot, and the planting operation becomes extremely troublesome. Furthermore, even if the seedlings are not so large, the planting position of the flowers is often determined by actually placing the seedlings.
In such a case, after placing the seedlings, the seedlings must be taken out of the pot and planted again, which is troublesome.

Furthermore, as long as such a conventional pot is used, it is very difficult to plant flowers and vegetable seedlings using a machine, which has been a factor inhibiting mechanization of flower gardens and vegetable farmers.

[0007] An object of the present invention is to solve the above-mentioned drawbacks of the conventional pot and to provide a seedling pot in which grown seedlings can be directly planted without being taken out of the pot.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a thin container formed of a material which is easily corroded or easily melted or decomposed in the ground, and has a bottom and a cylindrical shape. At least in the cylindrical portion, many roots are drilled so that the roots of the plant seedlings can easily pass through, but the culture soil is not easily spilled.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a pot showing an example of the present invention, and the same reference numerals as those in FIG. 1 indicate the same components.
The pot 1 comprises an upper part and a lower part 2 of a cylinder, and a large number of micro holes 6 are formed in the upper part and the lower part of the cylinder. The size of the micropores is selected so that the roots of the seedlings that pass through the seedlings pass through but the soil does not spill out much, and is usually preferably several millimeters.
Of course, the diameter of the hole varies considerably depending on the size of the pot and the type of plant to be grown, and also varies depending on the grain size of the soil used. Although a hole 3 for draining water is formed in the bottom, this hole is not always necessary. When a large number of holes 6 are formed in the bottom, these holes can also serve as drainage, so that it is not necessary to provide a large drainage hole.
In the present invention, it is not necessary to provide a large number of micro holes on the bottom surface. In the case where the root of the plant has the property of extending mainly in the horizontal direction, a large number of holes 6 may be provided only in the cylindrical portion. However, in this case, it is better to provide a hole 3 for draining water. The large number of micropores is not limited to a circular shape as shown in this figure, but may be a polygonal shape or a slit shape elongated in the vertical direction or the horizontal direction. Also, elongated slits may be provided at the top and bottom of the tube instead of the slits. These slits and cuts need not be provided in one direction, but may be provided randomly. Further, even if the slits and cuts are formed in a cross shape or the like, the effect is the same.

It is efficient that the pot 1 including the bottom 2 is integrally formed and formed. As an example, it is preferable to use paper, fine chips of wood, or a material obtained by pulverizing grass into granules or powder. By using such a material, the pot is spoiled by bacteria in the soil, or is naturally melted or decomposed with the soil moisture over time. Such a material is mixed with liquid glue and directly poured into a mold for molding, or a wide plate or sheet of a similar material is formed in advance, and a large number of holes, slits or holes are punched from the plate or sheet. It is formed into a pot while making a cut. The bonding agent such as liquid glue that solidifies the material is preferably a plant that does not remain harmful in the soil, is relatively weak so that the pot does not retain its shape for any time, and is degraded over time, etc. It is preferable that the tackiness disappears after about six months at most. When paper is used, the use of waste paper is better, and in this case, it may be made by a molding method like a normal paper cup. However, the strength of the paper is made as weak as possible, and one that easily rots or decomposes in the soil is used.

[0010] It is effective for raising seedlings if a fertilizer component is mixed during the molding of the pot or applied to the inside of the pot.

FIG. 3 shows an example of using such a pot. A is a state where seedlings 4 are planted in a pot in a pot,
This is a situation in which the root 7 has slightly exited from a number of minute holes, slits, and cuts 6. Such a seedling is planted in the field or flower bed 8 as it is with the pot. This state is shown in FIG. 3B. In this state, after several days to several months, the pot 1 rots, melts or decomposes and mixes into the soil 8 of the field, and the roots 4 of the seedlings protrude strongly in the soil 8 and grow. . As mentioned above, the pot is made of paper or fine chips of wood, and its strength is not so strong, so that the roots grow as the plant seedlings 4 grow, and in the process, micropores, slits or cuts are formed. The swelling or the breakage of the pot does not hinder the growth of the root 7.

As described above, as a material of the container or a glue material used for joining, harmful chemical substances, harmful substances remaining in the soil of a field or a flower bed for a long time may hinder the growth of seedlings, or cause pollution. Things that cause it must be avoided.

[0013]

When the seedlings are grown using the pot of the present invention, the roots of the early seedlings come out of a large number of micropores, slits or cuts provided on the side (and even the bottom) of the pot. Because the pot does not retain its original shape due to root growth or due to the nature of the pot material, the seedling can be planted as it is in a field or flower bed. Therefore, it is not necessary to take out the seedlings from the pot, so that the seedlings can be planted as soon as the planting position is determined. Also, when planting seedlings of thousands to tens of thousands of flowers, etc., the work efficiency is remarkably improved. In addition, the work of collecting empty pots as in the related art is not required.

Furthermore, when using a conventional pot, it was difficult to plant using a machine, but when using the pot of the present invention, since the shape is constant and there is no work to remove the pot, Using a large dedicated machine, several hundred or more seedlings can be loaded at a time, and only the operation of the machine can be used to uniformly, neatly, and quickly plant flower and vegetable seedlings.

Further, since a vegetable material is used for the pot, it rots and becomes compost, which also contributes to the formation of fertile soil.
