DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivation apparatus and a cultivation method for preventing a shogi from falling in the direction of a transplant row and falling on both left and right sides, and making the edible part of the onion soft white part longer. In particular, the present invention relates to a cultivation apparatus and a cultivation method suitable for open-field cultivation.

[0002]

2. Description of the Related Art As a green onion grows, the top leaf tip becomes heavier as it grows, so that even a small amount of wind pressure causes shogi to fall in the direction of the planting row or to the left and right sides of the planting row. As a result, there is a problem that the quality of green onion is reduced and the product yield is reduced.

[0003] That is, a fallen onion is not a so-called bend and is not a commercial product, but has to be disposed of or barely sold as a foreign product.

[0004] Various cultivation apparatuses have been proposed to solve such problems, but none of them have been sufficiently satisfactory.

[0005] In particular, in the case of open-field cultivation, it was impossible to cultivate soft onions. The reason is that in open-field cultivation, embankment is the mainstream, and it is necessary to use a machine about 4 to 5 times before growing and harvesting, but every time the embankment is cut, the growing roots are cut. caused by.

[0006] That is, when roots are cut by a machine, the occurrence of diseases increases, so that the frequency of controlling pests and insects increases and the production yield decreases.
In addition, the soft white part of the embankment to be used for edible roots is 30cm.
This is because it was impossible. In addition, the soft onion is a green onion whose soft part is 40 cm or more.

[0007]

SUMMARY OF THE INVENTION The invention according to claim 1 of the present invention solves the drawbacks associated with the conventional embankment in open-field cultivation, and increases the white root portion of the edible portion below the leaf sheath, It is an object of the present invention to provide a cultivation apparatus capable of obtaining a soft white onion of excellent quality in which the white root portion is white, which is clearly different from the dark green portion of the leaves.

Another object of the present invention is to provide a cultivation method capable of obtaining a soft onion of excellent quality as described above.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which light-shielding plates 2 and 2 'are disposed on both sides of an implantation row of green onions 1, and the upper ends of the light-shielding plates are pushed at predetermined intervals. 3 shows an example in which the upper ends of both light shielding plates 2 and 2 'are brought close to each other.

The two light shielding plates 2 and 2 'are, as shown in FIG.
A large number of air chambers 5 are formed by a large number of partition walls 4 formed from plastic in the length direction (the direction of the implant row).
The outer surface 6 is colored black for shielding light.

The light shielding plates 2 and 2 'used in the present invention are shown in FIG.
As shown in (1), any plate body having an air layer and having a light blocking effect and not being deformed freely may be used.

As the plate having the air layer, in addition to the above-mentioned plastics, a foamed plastic plate, a cardboard plate, or the like can be used.

Further, if it blocks sunlight, it does not have to be black, and any opaque plate may be used.

Concave stripes 7 are formed on the front and back surfaces of the light shielding plates 2 and 2 ′ along the partition wall 4. The outer surface does not need to be particularly uneven, but the inner surface that is in contact with the onion is preferably formed in an uneven or ancestral surface, from the viewpoint of preventing the onion from falling over shogi.

In the above embodiment, the push rod 3 is fitted with a ring 9 at the upper end of the rods 8 and 8 'which can be elastically bent, and pushes the rods 8 and 8' inward to form the light shielding plates 2 and 2 '. ′ Are made to approach each other. Note that a string may be used instead of the ring 9.

As the push rod 3, a single metal rod is formed by an acute V
The light shielding plates 2 and 2 ′ may be configured to be bent in the shape of a letter so that the light shielding plates 2 and 2 ′ are sandwiched and approached by the bent portion.

Further, a single metal rod is bent into a U-shape to form large and small push rods, and the small push rod presses the light shielding plates 2 ', 2 inside the adjacent implantation row, and the large push rod It may be formed so as to press the light shielding plates 2 and 2 ′ outside the adjacent implantation row.

Next, a method of cultivating onions using the onion softening apparatus of the present invention configured as described above will be described.

First, as shown in FIG. 3, a V-shaped fixed groove 10 is formed in a row to be implanted, and an onion is planted in the identified groove 10. The planting grooves 10 need not be V-shaped, but may be concave grooves.

After a lapse of about one month, as shown in FIG. 4, the settling grooves 10 are backfilled, and slightly filled to prevent the onions 1 from falling into shogi.

After about one month, as shown in FIG.
Tape piles 11, 11 'are provided on both sides of both ends of the planting groove 10.
To fix the left and right fall prevention tapes or cords 12 and 12 ′ to the tape piles at both ends of the planting groove 10.
A tape or string is stretched on both sides of the onion.

The height of the tapes or cords 12, 12 'is preferably from about the center of the length of the onion to about 2/3 the length of the onion.

After a lapse of about one month, as shown in FIG.
Light shields 2, 2 'having an air layer are arranged on both sides of the stem portion of the row of green onions which needs softening, and rod-shaped members 8, 8 are sandwiched at predetermined intervals on both sides of the light shield. ′
A ring 9 is fitted to the upper ends of the rods 8 and 8 ', and the rods 8
And 8 'are pushed inward to bring the upper ends of the light shielding plates 2, 2' close to each other.

By bringing the light-shielding plates 2 and 2 'close to each other, the opening at the upper end is closed with an onion, so that the inflow of light rays from the upper end can be almost completely prevented.

About one month later, the grown onions are harvested. The green onion obtained in this manner was a soft onion of excellent quality with no sunburn in the soft white portion and a long white root portion for edible use. In the figure, reference numeral 13 denotes an overlapping portion of the light shielding plate.

The height of the light-shielding plates 2 and 2 'is preferably slightly higher than the stalk portion requiring soft whiteness.

In the above embodiment, a light-shielding plate having a height of 50 cm was used, but a soft white onion having a white root portion of 42 to 43 cm was obtained.

The height of the light shielding plates 2 and 2 'is 47 cm to 55 cm.
cm is preferable, and the onion is 45
It is preferable to arrange the light shielding plate so as to be located at a height of about 55 cm.

According to the present invention, the onion can be prevented from falling on both the left and right sides by the light-shielding plate, and the shogi can be prevented from falling by fixing the push rod, so that the onion can be grown straight.

By laying a tape or the like at a predetermined height inside the light-shielding plate on both sides of the row of long onions, the falling of the green onion on both the left and right sides and the shogi can be prevented more reliably.

According to the present invention, since the light shielding plates are arranged on both sides of the green onion, the internal temperature can be made lower even when the external temperature is high, and the internal temperature can be made low even when the external temperature is low. Since it can be higher, a good quality soft onion can be obtained. High temperatures are especially unsuitable for green onion growth.

Specifically, during a time when the temperature is very high, the inside temperature is lower than the outside temperature by 2 ° C. to 3 ° C., and when the temperature is low, the inside temperature is raised by 1 ° C. to 2 ° C. I can do it.

Further, according to the present invention, since the light-shielding plate having the air layer is used, the sunburn of the onion is not seen,
Very good quality soft onion is obtained.

The cultivation apparatus and cultivation method of the present invention are particularly effective for open-field cultivation of soft onions, but can also be applied to house cultivation of soft onions. In house cultivation,
Very good results have been obtained with the above method.

[0039]

According to the present invention, in the open field cultivation, it is possible to easily obtain a soft green onion in which the soft white portion has grown straight up to 40 cm or more, which was impossible in the past. It eliminates the disadvantages associated with it, and increases the white root of the edible part below the leaf sheath, and because there is no sunburn, the white root is white with a clear white line clearly distinguishing from the dark green part of the leaves. It has an enormous effect of being obtained.
