Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivation container suitable for cultivating plants such as potatoes, root vegetables, peanuts, etc. at a position higher than the ground.

[0002]

2. Description of the Related Art Agricultural crops such as potatoes and root vegetables are cultivated by so-called soil cultivation in which seedlings are planted and grown along ridges formed on the ground surface of the cultivation area. In soil cultivation, a series of operations from planting to harvesting are often performed in a squatting or crouching position.Especially at the time of harvesting, there is heavy labor such as digging of crops, so the physical burden on workers is extremely high. It has become a big thing.

To improve such working conditions, cultivation apparatuses and cultivation containers as shown in FIGS. 7A and 7B have been proposed. Cultivation apparatus 70 shown in FIG.
Is disclosed in Japanese Patent Application Laid-Open No. 2-312524. In a ground space, a receiving portion 72 provided with a hole 71 on a bottom surface is installed substantially horizontally on a support portion 73, and a hole on the bottom surface of the receiving portion 72 is provided. A tubular body 74 protruding downward is detachably connected to 71, and the inside of the saucer part 72 and the tubular body 74 is filled with culture soil 75 and the like, and the root vegetables 76 planted in the saucer part 72 are removed. The root 77 is grown in the cylindrical body 74.

The cultivation container 90 shown in FIG. 7 (b) is disclosed in Japanese Patent Application Laid-Open No. 6-169645. A plurality of cultivation containers 90 are hung on a base 91, and these cultivation containers 90 Cultivate root vegetables such as burdock on the filled soil. The cultivation container 90 is a prefabricated container made of synthetic resin, and has an uneven plate 93 having a plurality of grooves formed in parallel with a flat plate 9.
4 are detachably attached to each other, and the uneven plate 93 and the flat plate 94 are mounted.
A space 95 for inserting the cultivated soil 92 is formed between the two.

[0005] Such a cultivation apparatus 70 and a cultivation container 90
If cultivation of root crops is carried out using cultivation, most of the necessary work during the cultivation period can be made upright, the harvesting work will be simplified, the overall cultivation work will be more efficient, and working conditions will be improved. be able to.

[0006]

In the cultivation apparatus 70 shown in FIG. 7 (a), a support portion 73, a tray portion 72 and the like are provided as means for holding a plurality of cylindrical bodies 74 at a position higher than the ground. However, since the weight of the tubular body 74 containing the seedlings of the root crops 76 and the culture soil 75 is considerably heavy, it is necessary to make the support portion 73 and the tray portion 72 for supporting them strong. It causes bloat and an increase in overall weight. Such enlargement of the members and an increase in the total weight not only increase the burden of transporting the constituent members of the cultivation apparatus 70 to the cultivation site, but also increase the burden of the installation work.

[0007] Further, since the cylindrical body 74 has a relatively durable structure premised on repeated use, when root vegetables and the like are cultivated, at the time of harvest, the root vegetables 76 are removed from the cylindrical body 74 together with the culture soil 75 and the like. If the root 77 is not pulled out, the crop cannot be collected, and the harvesting operation requires much labor and time.

Further, when it is necessary to disassemble and withdraw the cultivation apparatus 70 after the cultivation period, the burden of these operations is large, and a large space is required for storing the withdrawn various members.

In the cultivation container 90 shown in FIG. 7 (b), as in the cultivation apparatus 70 shown in FIG. 7 (a), as means for holding the plurality of cultivation containers 90 at a position higher than the ground,
A large number of members are required, such as a gantry 91 formed with a support 96 and a pier 97, and a moving frame 98 laid between the piers 97, and these members are not only carried in and assembled to a cultivation area, but also cultivated. A lot of labor and time is required for dismantling and retreating after the end of the period, and a large space is required for storing the retreated components.

Further, as a problem common to the cultivation apparatus 70 and the cultivation container 90, the arrangement interval of the cylindrical bodies 74 and the spaces 95 is determined by the interval between the holes 71 and the pitch of the waves of the uneven plate 93. It is difficult to change the inter-stock distance flexibly according to the type of crop to be cultivated, or to gradually change the inter-stock distance in accordance with the growth situation, because it is unchanged unless these are changed.

Further, the cylindrical body 74 constituting the cultivation apparatus 70
And the space 95 of the cultivation container 90 has a shape suitable for growing vertically long root vegetables such as burdock and radish, but since these shapes do not always coincide with the elongation region of the whole plant root, When root vegetables are cultivated using cultivation, seedlings, which are indispensable for growing harvested products, may not grow sufficiently. Further, the cultivation apparatus 70 and the cultivation container 90 are unsuitable for cultivation of potatoes, which require a great deal of time and labor for harvesting work, like root vegetables.

[0012] The problem to be solved by the present invention is that the growing condition of the plant is activated, the harvesting work of potatoes, root vegetables and the like can be simplified, and it is used as a component of an elevated cultivation apparatus. An object of the present invention is to provide a cultivation container capable of reducing the burden of transportation, assembling, withdrawal work, and the like, and reducing the storage space in the case where the cultivation is performed.

[0013]

The cultivation container of the present invention comprises:
It is characterized by being formed in a bag body with a synthetic resin film spread downward. With such a configuration, when the cultivation container is filled from the opening, the cultivation container expands and has a substantially truncated cone shape, so that planting is performed by sowing or planting the cultivation portion exposed at the opening. The roots of the plants can be expanded in the so-called divergent shape, which is the original growth form, in the cultivation in the shape of a truncated cone, so that the absorption of nutrients and moisture is improved, Growth is activated. Therefore, it is suitable not only for root crops that grow vertically in the soil, but also for growing potatoes that grow in a plurality distributed in a downward spread, and the growth state is activated and the yield is increased. Can be.

In addition, potatoes, root vegetables, which produce crops in the soil,
The growing area of the crop when peanuts are cultivated can be secured sufficiently wide, so that the yield can be increased.At the time of harvesting, the synthetic resin film constituting the cultivation container is cut with a cutter knife or the like. Since the potatoes and the like in the cultivated soil can be taken out only by cutting, the harvesting operation can be simplified.

Further, since the cultivation container of the present invention is formed of a thin and lightweight synthetic resin film, the cultivation container is placed on the ground and used as a component of an elevated cultivation apparatus. In addition, the burden of transporting, assembling, and removing work can be reduced, and the storage space can be reduced. Also,
Since the arrangement interval of the cultivation containers can be arbitrarily changed, the inter-stock distance can be set flexibly according to the type of the cultivated crop, or the inter-stock distance can be gradually changed according to the growth situation.

Further, by providing a hook member having a reinforcing function on the upper part of the bag body, the assemblability when forming an elevated cultivation apparatus using the cultivation container and the stability during use are improved. . As the hook member, a member provided with a skirt-shaped main body portion that can be attached to and detached from the upper portion of the bag body, and a hook-shaped locking portion that is formed to protrude from the skirt-shaped main body portion are preferable.

As the synthetic resin film constituting the container for cultivation, a film of polyethylene, polyethylene terephthalate, polypropylene, nylon or the like is suitable, and a laminated film obtained by laminating these films can also be used. In addition, a decomposable film that is decomposed by microorganisms or ultraviolet light can be used. In addition, by using a gas-permeable film as the film, it is possible to ensure the gas permeability and drainage suitable for growing the plant, so that the growth of the plant planted in the filled soil can be promoted. In addition, as a breathable film, a porous film in which a large number of fine through holes are arranged on the entire surface or partially, a woven film or a nonwoven film formed of fine fibers, or a composite film in which these are laminated Is preferred.

Further, by using a light-shielding film as the film, it is possible to prevent sunlight from being irradiated on the cultivated soil filled in the cultivation container, so that root growth can be improved. In this case, if a black film or the like is used as the light-shielding film, not only the light-shielding property but also the heat absorption rate is increased, so that the heating effect of the soil can be obtained.

As described above, since the inner diameter r of the opening 13 of the cultivation container 10 is smaller than the minimum inner diameter R of the bottom 14, as shown in FIG. It has a substantially truncated conical shape bulging downward. Therefore, as shown in FIG. 2, the stability when the cultivation container 10 is placed on the ground 17 and used as a part of the elevated cultivation apparatus is also good. In addition, since air, water vapor, and moisture can move through the fine through holes 11 of the film 12, the air permeability and drainage of the cultivation soil 16 can be secured.
The environment becomes suitable for the cultivation of the plant P, and the growth state of the plant P also becomes favorable.

As shown in FIG. 3, when potato seedlings 19, which are one of the potatoes whose crops are harvested, are cultivated in the cultivation soil 16 using the cultivation container 10, the root growth form of the plant is equal to the original growth form. In the so-called flared soil 16, the growing area of the root 19 r and the growing area of the harvested potato 19 a (see FIG. 4) can be sufficiently widened, so that the potato seedling 19 and the potato The growth state of 19a is activated, and the yield can be increased.

When the growth of the potato seedlings 19 has been completed and the harvest time has come, as shown in FIG. 4, the film 12 constituting the cultivation container 10 is cut with a cutter knife C, so that the potato 19a in the cultivation soil 16 can be easily removed. Since it can be taken out, the harvesting work can be greatly simplified, and the potato 1
