Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for hydroponics of strawberry seedlings, and more particularly to a method for hydroponically growing strawberry seedlings that efficiently grows a large number of child strains from the parent strain of strawberry in a small cultivation area.

[0002]

2. Description of the Related Art A culture method shown in FIG. 4 has been widely used as a conventional method for growing a larger number of strawberry seedlings than a strawberry parent strain. In this method, the parent strain 2 is vegetated in the medium 1 at a predetermined interval, and the offspring 4a to 4d and the like are germinated one after another from the stem portion 3 growing along the surface of the medium 1, and after growing each offspring while being rooted in the medium. The method is to separate and collect them between the stems 3. In addition, the stem portion 3 normally branches and grows in a dendritic manner from one parent strain. And each stem 3
Many child strains germinate. However, since this method cultivates strawberry seedlings on the medium 1 in a plane, the medium 1 requires a large cultivation area, and the parent and child strains are grounded on the medium, so that the medium is contaminated with pathogenic bacteria. And there is a problem such as a high risk rate of causing disease in strawberry seedlings.

Therefore, in order to solve such a problem,
A method combining hydroponics and three-dimensional cultivation has been proposed. In this method, as shown in FIG. 5, a hydroponic cultivation bed 7 is provided on a stand 6 standing upright from the ground 5 such as soil,
In this method, the stem portion 3 growing from the parent strain 2 vegetated therein is extended downward to grow the child strains 4a, 4b and the like. The offspring 4a, 4b, etc. that germinate one after another from the stem 3 have roots, respectively, but they only come into contact with air. However, the abundant water and nutrients from the hydroponic bed 7 are absorbed by the parent strain 2 and supplied to the child strain through the stem portion 3, so that the child strain is sufficiently grown. This three-dimensional hydroponic cultivation method has an advantage that the cultivation area per unit yield is small and the parent strain 2 and the child strains 4a, 4b and the like do not come into contact with the medium, so that the risk rate of disease occurrence is low.

[0004]

However, in the proposed three-dimensional hydroponic cultivation method described above, a plurality of stalks 3 branched from each parent strain 2 and hanging downward are entangled with each other and overlap each other to prevent the sun from falling. There was a problem that the growth of the child strain on the other side was significantly impaired. Moreover, as the stem 3 and the sub-plants grow, the entire stem is pulled downward by its weight, the tip reaches the ground 5 such as soil relatively early, and the sub-germinated sub-plant is grounded. There was a fear. Further, there is a problem that it is difficult to collect the grown strains because the stem 3 and the strains are entangled with each other. Then, this invention makes it a subject to provide the new cultivation method of the strawberry seedling which solves these problems.

[0005]

[Means for Solving the Problems] That is, in the method for cultivating strawberry seedlings of the present invention, a hydroponic cultivation bed in which the parent strain of strawberry is planted is provided on the upper part of the base, and the stem portion growing from the strawberry parent strain is extended downward. It is the one. Then, a plurality of stages of horizontal strings are stretched on a plurality of vertical support legs provided on the pedestal, and strawberry progeny, etc. that sprout one after another on the growing stem part are sprouting in order from the upper horizontal string to the lower horizontal string. The feature is that they are fixed in sequence. In a preferred embodiment of the present invention, when the sub-plants and the like are fixed to the horizontal cord, a fixing tool is slidably connected to the horizontal cord and the strawberry sub-plants and the like are fixed thereto. As this fixture, a bind wire that can be bent and can hold the bent state is preferably used. Such a bind line can be used to fix a child stock or the like and to slidably connect it to a horizontal cord with one touch.

In another preferred embodiment of the present invention, the horizontal cords at the respective stages are stretched around the outer sides of the supporting legs. By doing so, the yield of strawberry seedlings per cultivated area can be further increased. In still another preferred embodiment of the present invention, a plurality of vertical strings in the up-down direction are stretched on a cradle at predetermined intervals, and a ring body is attached to each vertical string at a portion intersecting with the horizontal string. Make sure the string is inserted. By doing so, it is possible to easily pull out the horizontal cord.
In still another preferred embodiment of the present invention, when collecting strawberry progeny strains grown to a predetermined size,
The horizontal cord is pulled out while the fixing tool is left on the strawberry stump and the like, and the stem portion between each stump is cut.

[0007]

The method for cultivating strawberry seedlings according to the present invention is such that the strawberry seedlings that germinate in sequence from the parent strain of the strawberry planted on the hydroponic bed on the top of the cradle as described above to the stalks that are downwardly sown Since the cords are fixed to the lower horizontal cord one by one, it is possible to prevent the stems from being entangled with each other and to disperse them at appropriate intervals. As a result, the problem of overlapping and leaving the sunless seedlings is solved, and strawberry seedlings can be efficiently grown. In addition, since the stems that sprout one after another on the stem were fixed to the horizontal cord and then the weight of the previous portion was supported by the fixed portion, as the stem and the seedlings grew, the weight of the stem was increased by that weight. There is no problem that the whole is pulled downward and the tip reaches the ground such as soil relatively early. Furthermore, since the stem and the substrain are not entangled with each other, it is easy to collect the grown substrain. Moreover, since it is possible to support the same generation of child strains generated from multiple parent strains, it is easy to achieve consistent quality by matching the growth rate of each stage and harvesting each stage. .

Embodiments of the present invention will now be described with reference to the drawings.
FIG. 1 is an overall perspective view showing a cultivation apparatus for carrying out the present invention and a state in which strawberry seedlings are grown therein, and FIG. 2 is a partially enlarged front view thereof. The cultivating device 10 includes a gantry 11 and a hydroponic cultivation bed 12 provided on the pedestal 11. The pedestal 11 includes a foundation portion 13 installed on the ground such as soil,
A plurality of pieces (in this example, 4
It is composed of a supporting leg 14 of (book) and an upper connecting member 15 for connecting between the upper portions of the supporting legs 14. And foundation part 1
3, the supporting leg 14 and the upper connecting member 15 may be made of resin or metal pipe as shown in the drawing, or steel material such as angle material. The lower end of each supporting leg 14 is buried in the soil.

As the hydroponic culture bed 12, those conventionally used in this field can be used. In this example, a box-shaped bed body 17 having an elongated rectangular shape and an open upper portion
And a support member 18 composed of a pair of pipes and the like which are horizontally attached in parallel to both outer sides in the longitudinal direction. Each supporting leg 14 of the gantry 11 is arranged in a rectangular shape so as to match the elongated bed body 17. It should be noted that support members 19 and 20 for supporting the lower surface of the bed body 17 are provided between the upper connecting members 15. Further, the supply pipe 26 omitted in FIG. 1 has a hydroponic bed 1 as shown in FIGS. 6 and 7.
2 is attached to the upper part of the pipe 2, and the supply pipe 26 has a large number of discharge holes 31.
Has been drilled. The supply pipe 26 communicates with a nutrient solution tank 28 via a gate valve 30 and a pump 29.
Then, the nutrient solution 32 is discharged from the discharge hole 31 of the supply pipe 26 as shown in FIG. The discharged nutrient solution 32 permeates the medium and is guided to the discharge pipe 27. In FIG. 7, 33
Is a root entry prevention material, which prevents root entry of strawberry seedlings,
The penetration of the nutrient solution 32 is known and possible.

A plurality of stages of horizontal cords 21 are stretched around the outside of each support leg 14 at predetermined intervals, and each end is fastened to a part of the support leg 14. Further, a plurality of vertical cords 22 are hung from the support member 18 at predetermined intervals, and a ring body 23 such as a washer is fastened to a portion that intersects with the horizontal cords 21 in each step. And those ring bodies 23
A horizontal string 21 is slidably inserted in the, and its intermediate portion is supported at a predetermined interval. Although the vertical string 22 is hung only from the front side of the gantry 11 in FIG.
Similarly, it is hung from both side surfaces and the back surface side. Vertical string 2
The upper end of 2 is fastened to the support member 18, but instead of providing the support member 18, it is also possible to attach an elongated support member that intersects the upper connection member 15 of the gantry 11 and fasten the vertical cord 22 thereto.

A plurality of strawberry parent strains 2 are planted at predetermined intervals in the peripheral portion of the bed body 17, and a plurality of stalks 3 grow downward from the bed body 17 from there. During the growth of these stems 3, the first-generation offspring 4a first germinate from the tip of the stem 3, and then the second-generation offspring 4b germinates from the tip of the further grown stem 3. In this way, the growth of the stem portion 3 and the germination of the sub-strains are alternately repeated, and the third-generation sub-strain 4c and the fourth-generation sub-strain 4d are germinated one after another. Figure 2
As shown in FIG. 4, each of the substocks 4a, 4b, etc. is fixed to the horizontal cord 21 by a fixture 24 such as a bind wire so as to be horizontally movable. That is, in the example shown in FIG. 2, a bind wire that is bendable and capable of holding that state is used, and the tip portion of the bind wire is slidably engaged with the horizontal cord 21 to be curved in a ring shape and the substock 4a,
By cutting a part of 4b and the like and then cutting them, each subsidiary 4a, 4b and the like is fixed to the horizontal cord 21 so as to be horizontally movable. By doing so, the sub-strains can be moved along the horizontal cord 21 as shown in the drawing, and the sub-strains in the lateral direction can be dispersed and arranged so as not to overlap each other to make their growth uniform. As the bind wire, a core wire having the above-mentioned characteristics covered with a resin layer (commercially available under the trade name of color tie) is more preferable from the viewpoint of durability.

When horizontally fixing each sub-strain to the horizontal cord 21, it is preferable that the same-generation sub-spores germinated on each stem are fixed to the same horizontal cord 21. By fixing in such a manner, it is possible to arrange child strains (strawberry seedlings) having the same quality or growing condition in each stage, and thus they can be easily collected separately. The reason for such separate collection is that the first-generation child strains are generally called "Taro strains" and the second-generation child strains are called "Jiro strains". They are generally aging strains with poor harvestability and low grade. Therefore, it is preferable to sort the strawberry seedlings in advance according to such a grade at the time of shipping or the next cultivation step.

FIG. 3 shows a state in which a strawberry strain grown to a predetermined size is being collected. First of all, the collection method is 4
By cutting the stem portion 3 between a, 4b, 4c, etc. with the scissors 25, then removing the fastening of the end portion from the upper horizontal string 21 and sequentially pulling it out, each sub-plant can be separately collected for each generation. At that time, since the intermediate portion of the horizontal cord 21 is slidably inserted into the ring body 23, it can be easily pulled out. As an alternative method, first, each horizontal cord 21 may be pulled out to collect a group of sub-plants for each stalk 3, and then each sub-plant may be separated. A fixture 24 is attached to each of the strains collected as described above.
However, it does not matter as a strawberry seedling in the next cultivation process, so it may be left as it is.

EFFECTS OF THE INVENTION Since the method for cultivating strawberry seedlings according to the present invention is constructed as described above, it is possible to avoid entanglement of a plurality of stalks with each other and to disperse them uniformly at appropriate intervals. You can Therefore, unlike the conventional case, there is no problem that overlapping and sun-resistant child strains are generated, and strawberry seedlings can be efficiently grown. In addition, since the stems that germinate one after another on the stem are fixed to the horizontal cords of different stages, and the weight of the previous portion is dispersed and supported by the fixed portion, excessive weight is not added to the stem, There is no problem that the entire stem is pulled downward by its weight as the stem and the offspring grow, and the tip reaches the ground such as soil relatively early. Furthermore, since the stem and the substrain are not entangled with each other, it is extremely easy to collect the grown substrain.

As described above, when fixing the stumps to the horizontal cord, a fixture made of a bind wire that is bendable and can hold the curved state is used, and it is slidably connected to the horizontal cord and at the same time, the strawberries' stumps are used. By fixing
It is possible to fix the subsidiary stock and slidably connect it to the horizontal cord with one touch. Further, when the horizontal cords of each of the above stages are stretched around the supporting legs, if they are stretched around the outside of each supporting leg, the yield of strawberry seedlings per cultivated area can be further increased. Further, in addition to the above-mentioned horizontal cords, a plurality of vertical cords extending in the vertical direction are stretched on the frame at predetermined intervals, and a ring body is attached to each vertical cord at a portion intersecting with the horizontal cords, and the horizontal cords are inserted into the ring body. As a result, the intermediate portion of the horizontal cord is supported by the vertical cord so as not to hang downward, and the horizontal cord can be easily pulled out when collecting the offspring that have grown to a predetermined size.
