Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a method for cultivating various young vegetables that grow in a relatively short period of time, such as Japanese radish.
This is a cultivation method that ensures the reliable growth of young seedlings after they have been developed into very good seedlings.

<Prior art and problems to be solved by the invention> Conventionally, the method for cultivating young vegetables, such as Japanese radish, involves placing soil or a culture solution in a cultivation box made of wood or synthetic resin, and then sowing seeds on top of the cultivation box. The seedlings were grown with appropriate watering, and when harvesting and shipping, the daikon radishes were pulled out of the cultivation boxes, washed, and then repacked into shipping packaging containers for transportation or sale.

However, in the above conventional method, the cultivation boxes overlap and are bulky, making them difficult to handle, and cleaning or refilling work at the time of shipping is time-consuming, which hinders prompt supply to consumers and requires cleaning or refilling work. The daikon radish inside is damaged,
There were also problems where quality was likely to deteriorate.

In addition, molded plastic trays and the like are used as packaging containers for shipping, but daikon radish tends to dry out during transportation, causing problems such as loss of freshness and spoilage.

In particular, recently, the main body of the box has a cultivation chamber with holes in the bottom formed into squares, a container that fits below the main body to supply cultivation liquid to the main body, and even young vegetables such as Japanese radish that grow. A cultivation device was also proposed in which a lid was combined with a lid to adjust the height of the cultivation chamber (Japanese Patent Laid-Open No. 179419/1983), but the box-shaped body was a so-called bead molded product made of foam particles molded in a mold. Because the adjacent rooms share a common side wall, there is no flexibility in terms of plant growth, and further improvements are needed in terms of air circulation. It was difficult to stack the cultivation containers with some of them inserted, and a large amount of space was required in the cultivation containers even during germination.
Furthermore, the cultivation device is of a type that can be used independently, and is not suitable for linking many cultivation devices together for simultaneous cultivation. Moreover, it is necessary to transfer the container to another transport container at the time of shipment, and the above-mentioned conventional inconveniences cannot be sufficiently solved.

Therefore, the present invention attempts to provide a cultivation method that can overcome the drawbacks of the conventional cultivation methods described above.

<Means for Solving the Problems> A feature of the cultivation method of the present invention for solving the above problems is that the entire cultivation method is integrally formed of a synthetic resin sheet, and a plurality of recessed cultivation compartments are arranged side by side. At the same time, the bottom surface of the recessed compartment has a plurality of protrusions recessed from the inside, and the protrusions have through holes for water passage. After a seeding pine is laid, seeds are sown on the seeding pine, and then the cultivation containers are stacked in multiple tiers to such an extent that the protruding lower bottoms of the cultivation containers are in contact with or close to the seeds, so that the seeds germinate and/or
Alternatively, after rooting, the stacked state is released and cultivation is performed by arranging the cultivation containers side by side in individual cultivation containers.

<Example> Next, an example of the present invention will be illustrated below with reference to the drawings together with a cultivation container and the like.

In Figures 1 to 3, reference numeral 1 indicates the entire cultivation container used in the method of the present invention, which is integrally formed from a synthetic resin sheet such as a foamed polystyrene sheet by sheet forming means such as vacuum forming. , the whole is formed into a substantially rectangular shape.

Reference numeral 10 denotes a recessed section for cultivation, which is recessed downward in the container 1 in consideration of the stacking of containers, and is formed into a substantially rectangular parallelepiped shape with a slight taper, and a plurality of recessed sections 10... They are arranged vertically and horizontally. Adjacent recessed sections 10 are arranged so that the upper edge of the side wall 11 is connected to the continuous portion 1 on the upper surface of the container 1 serving as the upper end.
2, and below the container 1, the side walls 11 of each recessed section 10 connected from the bottom surface are arranged independently with a space between them.

In addition, in the intersecting part 13 where the four recessed sections 10 are adjacent to each other, the continuous part 12 is recessed slightly below the upper surface of the container 1, and at this recessed intersecting part 13, the container The entire structure is reinforced and prevented from deforming.

On the bottom surface of the recessed section 10, a plurality of protrusions 14 are recessed from the inside and protrude from the bottom surface, and the back surfaces of the protrusions 14 protrude from the lower surface of the container 1. In addition, a plurality of water passage through holes 15 are formed in the protrusion 14 . The through hole 15 may be formed not only at the bottom of the protrusion 14, but also from the side, from the side to the bottom, or may be formed in a mixture of these.

Among the cultivation containers 1 described above, the recessed compartment 10
As long as the area is large enough to grow one unit of Daikon radish during transportation and sales, which will be described later, the planar shape can be any shape such as a rectangle, square, polygon, or circle. Section 10
The depth of the radish can be considerably lower than the total height of the radish if the radish can be protected during transportation after completion of growth. The external dimensions of the container 1 and the number of recessed sections 10 formed can be changed depending on the size of the cultivation water gutter described later and the size of one recessed section 10. The number of rows or columns of 10 can also be changed as appropriate. In the case of the figure, the cultivation container 1 is, for example,
Width 60cm x height 30cm x depth 6cm, of which the protrusion 14 has a protrusion of 8mm, and the recessed section 10 is 6.5 x 9.
24 cm are formed.

The protrusion 14 formed on the bottom surface of the recessed section 10 is
This is effective for raising the seeding pine (described later) from the bottom to facilitate water passage, reinforcing the bottom, and supporting the entire container 1, but the shape and number of the protrusions 14 can be changed freely, and the current situation is Instead of the protrusion 14, a circular or rectangular protrusion may be formed.

As the synthetic resin sheet forming the cultivation container 1, foamed sheets made of various synthetic resins such as polystyrene, polyethylene, and polypropylene are lightweight and easy to handle, and have excellent warm-shock protection against Japanese radish. A non-foamed sheet consisting of can also be used.

Next, when the above-mentioned cultivation container 1 is used, a seeding mat 2 made of water-absorbing foam, such as open-cell polyurethane foam, is inserted and laid on the inner bottom surface of each recessed section 10. .

In addition, as the seeding mat 2, a porous body with water-retaining or water-permeable fine pores, or a molded body of fibrous material with fine pores can be freely used, such as activated carbon fiber or activated carbon. The molded body is suitable because it also has a water filtering effect, and paper, nonwoven fabric, etc. can also be used. The sowing mat 2 has a shape that approximately matches the inner bottom surface of the recessed section 10, and has a thickness that is sufficient to retain the amount of water necessary for growth.

Next, a method for cultivating Japanese radish using the cultivation container 1 will be described.

First, the seeding pine 2 is laid on the bottom surface of the recessed section 10 in each cultivation container 1, and the seeding pine 2
After sowing an appropriate number of seeds on top of the cultivation container 1,
1... are stacked together in multiple stages (see Figure 4). That is, the recessed section 10 of the upper cultivation container 1 is different from the recessed section 10 of the lower cultivation container 1.
The cultivation containers are stacked in multiple stages to the extent that the lower bottom of the protrusion 14 of the recessed section 10 on the upper stage touches or comes close to the seeds K1 on the lower stage.
Then, water is added to the seeds K1 by water retention in the sowing pine 2 itself or by water passing downward from the top cultivation container 1, and the roots K2 of the seeds are always directed downward while regulating the upper part of the seeds as described above. While directing the seedlings to germinate and/or root, the seedlings are grown into young seedlings.

After germination as young seedlings, the stacking of the plurality of cultivation containers 1 is released and the seedlings are individually arranged side by side, and the seedlings are further grown in the recessed section 10 for each cultivation container. Regarding the growth of each individual cultivation container, the side edge of the cultivation container 1 is placed on the protrusion 30 of the cultivation water gutter 3, and the water gutter 3 is placed side by side.
Water is allowed to permeate into the seeding pine 2 through the water passage through hole 15 of the cultivation container 1, and the seeds are allowed to grow while being supplied with water (see FIG. 5).

According to the above example, during the germination stage of growing seeds into young seedlings, it is possible to grow unique young seedlings by stacking the cultivation containers in multiple tiers so that the roots are oriented downward, and water can also be passed through the cultivation in the upper tier. If this is done from the container, water can be passed sequentially to the lower cultivation containers, making it an extremely easy method for growing young seedlings.

After germination and seedling growth, the containers can be unstacked and the cultivation containers in which the seedlings have been grown can be returned to the parallel state, making it convenient to grow daikon radish.

Note that the timing for releasing the stacking of the cultivation containers 1, 1 is determined based on empirical rules since the growth state differs depending on the type of plant and is not constant. For example, in the case of the above Kaiware radish,
Since germination and/or rooting of seedlings from seeds takes about one day and one night, the above-mentioned stacking may be unstacked and arranged side by side after one day and one night. After that, in about 5 to 6 days, the daikon radish reaches a state of growth that can be shipped.

Next, once the daikon radish K has grown, it is shipped. At the time of shipping, the entire cultivation container 1 taken out from the water gutter 3 can be handled, but for convenience during later sales, etc., it may be divided into an appropriate number of recessed compartments 10 and handled.

That is, the continuous portion 1 of each recessed section 10 in the container 1
2 is cut with a means such as a nichrome cutter and divided into 10 individual recessed sections, and each divided recessed section 10 is left as it is or wrapped with wrap film or plastic film, It will be used for subsequent transportation, storage, or sales display (see Figure 6).

In addition, in the above-mentioned division, in addition to cutting each recessed section 10, several recessed sections 10 can be cut and divided into one unit.

The above-mentioned cultivation container 1 contains not only Japanese radish, but also bean sprouts, alfalfa (Japanese alfalfa),
It can be used to cultivate various young vegetables that grow in a relatively short period of time, such as watercress and sunny lettuce. For example, when implementing it as a cultivation container for sunny lettuce, it is necessary to form the recessed section 10 in consideration of the space in each growing state. (See Figure 7).

<Effects of the Invention> According to the invention as described above, the cultivation container used is made of a synthetic resin sheet, and a plurality of recessed cultivation compartments are arranged in parallel, and the bottom of each recessed compartment is recessed from the inside. The seeding pine is placed inside the cultivation container, and the seeds of young vegetables such as Japanese radish are sown on the seeding pine and grown. During growth controlled by the side walls of the compartment, the plants can grow straight without bending or lopsided, and are convenient for growing young seedlings by stacking cultivation containers.

In addition, since the entire cultivation container is made of thin sheet material, it is easy to carry and handle.
It is also easy to move within the cultivation water gutter during cultivation.

The same cultivation container can be used from seedling development to growth, and when shipping grown young vegetables, the entire cultivation container can be used as a shipping container, or it can be cut into arbitrary units of recessed sections. It may be divided and handled individually, and in either case, the cultivation container can be used as a container for transportation and sale.

Therefore, the conventional work of collecting and washing young vegetables and refilling them into containers for transportation and sales is completely unnecessary, which is highly effective in speeding up distribution work and reducing distribution costs.

In particular, the work of cutting and dividing the recessed compartments described above is extremely easy and quick, as it simply involves cutting a thin synthetic resin sheet at the continuous section on the top of the container. Because the side wall remains all the way around to the upper end, the young vegetables can be well protected even after shipping, and are convenient to handle when selling.

Furthermore, for cultivation purposes, a cultivation container is used in which the bottom of the recessed section is formed with a protrusion that is recessed from the inside, and a through hole for water passage is formed in the protrusion, so that the space between the side walls is reduced. Together, they have the advantage of improving air circulation, preventing root burrowing, and improving moisture circulation during growth.

Therefore, according to the present invention, it is a cultivation method that allows the cultivation of young vegetables such as Japanese radish from seeds to seedlings and growth in the same container.
Not only does it not require refilling from the seedling stage to the growing stage, it also eliminates the need for harvesting from the cultivation area, cleaning, and refilling into shipping containers, and greatly contributes to improving production efficiency and reducing production costs. It can exhibit various excellent effects.
