Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a high-growth container for cultivating strawberries, leafy vegetables, flowers, root vegetables, etc. at a position higher than the ground surface.

[0002]

2. Description of the Related Art When strawberry, leafy vegetables, flowers, root vegetables, etc. are cultivated, a method called soil cultivation is adopted in which seedlings are planted and grown along ridges formed on the ground surface of the cultivated area. .
In soil cultivation, a series of operations from raising seedlings to harvesting are often performed in a middle waist or crouched position. The physical burden on the person is enormous.

In order to improve such harsh working conditions, development of a cultivation container in which a worker can work while standing up,
Improvements and research on new cultivation techniques have been carried out, and as one of them, a cultivation method called so-called elevated cultivation has been partially implemented.

The applicant of the present invention has also developed a cultivating container for strawberries and the like, which requires less amount of soil and has good root growth (see Japanese Utility Model Publication No. 6-34437). We are developing a device for holding water and an auxiliary tool suitable for watering and fertilizing (see Japanese Utility Model Publication No. 6-16495). By combining these cultivation containers and devices, it is possible to improve working conditions.

FIG. 7 is a perspective view showing a state in which the cultivation container having the auxiliary tool set is held by a holding device. As shown in this figure, the holding device 80 is composed of a frame 81, columns 82, etc., and has a tapered cylindrical cultivation container 9
By holding 1 and the auxiliary tool 92 for watering / fertilizing with the holding device 80, the standing work can be performed, so that the efficiency of the cultivation work and the working conditions can be improved.

On the other hand, as a method of holding the cultivation container at a position higher than the ground surface, the present applicant has developed a method of holding a cultivation container having a shape in which a plurality of container bodies are connected by a connecting member, on a mount. However, it is disclosed in JP-A-8-298870.

FIG. 8 is a perspective view showing an example of the cultivating apparatus according to the above publication. The cultivating containers 95 are formed by continuously forming a part of the upper end of a container body 96 made of a synthetic resin to form 10 containers. The container body groups 97a and 97b having a shape in which the container bodies of are connected in a straight line form
It has a structure in which the upper portions of a and 97b are connected by a connecting member 98.

By using this cultivating device, it is possible to perform a standing operation, and a large number of conventional cultivating containers can be locked to the frame 99 by one locking operation.
The work of locking the cultivation container can be made efficient.

[0009]

In the case of the conventional high-growth cultivation apparatus, regardless of whether the cultivation container is a single container or a continuous container, it is necessary to fill the container with soil for each container. Therefore, in large-scale cultivation using a large number of cultivation containers, a large amount of time and labor are required for the installation work and the soil filling work.

Further, since the cultivation container has a structure in which it is suspended from the holding device, the holding device tends to occupy a larger proportion than the portion actually contributing to cultivation. For this reason, it takes a lot of time to transport the device, and a large space is required for the installation, so that it is difficult to adopt it when the cultivation area is small.

After the cultivation season,
Not only a great deal of time and labor is spent on the work of discharging the soil in the cultivation container and the work of removing the devices, but also a large space is required to store these cultivation containers and holding devices.

Further, since the conventional high-cultivation apparatus has a relatively large size and a complicated structure, it takes a lot of time and labor to manufacture it, and a large amount of raw materials such as synthetic resin is required.
High cost. For this reason, it is difficult for small-scale farmers with a small cultivation area to adopt it.

Therefore, the problem to be solved by the present invention is that standing work is possible, the amount of soil, water, fertilizer, etc. used can be reduced, installation and removal work is easy, and the storage space is small. An object is to provide a low-cost high-rise cultivation container.

[0014]

In order to solve the above-mentioned problems, the high-cultivation container of the present invention has a structure in which a plurality of flexible sheets which are superposed are provided with a plurality of linear fixing portions. And a holding means for holding the cultivated soil accommodating portion on the ground in an upright state.

According to the high-cultivation container of the present invention, the plant can be cultivated by filling the cultivating soil storage portion held in the standing state by the holding means with the cultivating soil. In this way, plant cultivation can be performed with the soil filled in the standing soil containing portion, so installation work is easy, and if the soil is discharged after the cultivation is completed, the soil containing portion will have the original flexible sheet shape. Since it returns to, it is easy to remove it.

[0016] Further, since the plant for cultivating the plant is cultivated with the cultivating soil accommodating portion standing upright on the ground in this high-growth container, standing work is possible, and the cultivating soil to be used is filled to the cultivating soil accommodating portion. Since the amount is sufficient, the amount of soil used can be small, which can reduce the amount of water and fertilizer used. Further, since the lower end of the flexible sheet is grounded, the temperature of the ground is transmitted through the flexible sheet and spreads throughout the high-growth cultivation container, and the heat retaining function is excellent.

Further, in the state where the cultivation soil container is not filled with the cultivation soil, this high cultivation container has a planar shape in which a plurality of flexible sheets are superposed, so that it is not bulky and can be folded or rolled into a roll shape. Since it is also possible, the storage space is small and it is easy to carry. Further, since it has a simple structure, it is easy to manufacture, the amount of raw materials used is small, and the cost is low.

Here, as a means for fixing the above-mentioned plurality of laminated flexible sheets in a linear shape, an adhesive, pressure bonding,
Thermocompression bonding, sewing, eyelets, etc. can be adopted.

Further, as a holding means for holding the culture soil accommodating portion in an upright state, a support member installed on the ground and an upper edge of the flexible sheet are formed to extend and can be locked to the support member. The structure may include a locking portion. As a result, the cultivation soil storage portion and the locking portion can be integrally formed, which facilitates manufacturing, and when filling the cultivation soil storage portion in the upright state, the locking portion guides the cultivation soil into the cultivation soil storage portion. Workability is improved.

The locking portion may have a structure in which a cylindrical portion through which the support member can be inserted is formed. With such a structure, the locking portion can be securely locked to the support member only by inserting the support member into the cylindrical portion, and the attachment / detachment work between the support member and the cylindrical portion can be performed. It will be easy.

Further, the culture soil accommodating portion may be tapered. With such a shape, it is possible to facilitate the work of filling and discharging the soil into the soil accommodating portion. In addition, since the soil filled in the soil accommodating portion can be held in an inclined state, when a plant such as a strawberry having the property that generation of new roots becomes active when held in an inclined state is cultivated, it grows. Can be activated, and the sales can be increased.

Further, the lower edge of the flexible sheet may be extended to form a mulching sheet portion. With such a structure, when the cultivating soil accommodating portion is held upright on the ridge formed on the ground, it becomes possible to cover the surface of the ridge with the mulching sheet portion. The same function can be exerted.

In this case, the mulching seat portion may be formed with a cylindrical portion through which the supporting member can be inserted.
With such a structure, the mulching seat part can be locked to the support member with the top part up, so that unlike the above-mentioned usage, the upside down of the soil storage part can be used upside down. become able to. Therefore, it is possible to use the top and bottom of the high-growth cultivation container alternately every season, and thereby, it is possible to prevent the flexible sheet from being unbalanced such as stain or damage.

The flexible sheet may be cut along the linear fixing portion. Here, the term “freely cut” means that a person can cut without using a blade or the like, only by applying force. By allowing the flexible sheet to be cut along the linear fixing portion, it is possible to install the flexible sheet while cutting it to an appropriate length in the cultivation area, so that the installation work becomes easy. Also, when adopting a cultivation method in which seedlings of plants grown in the soil storage unit for a certain period of time are transferred to another place and planted, it is possible to perform transplanting work separately for each soil storage unit. , Workability is improved.

The flexible sheet is a synthetic resin film,
It can be formed of at least one of paper, cloth, and non-woven fabric. When a synthetic resin film is used as the flexible sheet, it is possible to form the soil accommodating portion having excellent airtightness, corrosion resistance, and durability. Further, when paper, cloth, or non-woven fabric is used, it is possible to form an air-permeable cultivating soil accommodating portion and no harmful gas is generated during combustion, so that incineration and disposal is facilitated. The flexible sheet may be transparent or opaque, but by using a material with good thermal conductivity that easily transmits the outside air temperature, it is possible to grow roots in the soil filled in the soil storage part. It can be activated.

Further, by using two or more kinds of materials such as synthetic resin film, paper, cloth, and non-woven fabric in combination, it is possible to form a cultivating soil accommodating section having the characteristics of each material, and thus a plant to be cultivated. It is desirable to form a flexible sheet by selecting an appropriate material in accordance with the type of rice, the weather conditions of the cultivated place, and the like.
