DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevated cultivation apparatus for growing strawberries, leafy vegetables, flowers and the like at a position higher than the ground surface.

[0002]

2. Description of the Related Art When growing strawberries and leafy vegetables, a so-called soil cultivation method has conventionally been adopted in which seedlings are planted and cultivated along ridges formed on the ground of the cultivation area.
In the case of soil cultivation, a series of operations from raising seedlings to harvesting are often performed in a squatting or crouching position, and at the time of regular planting, they involve heavy labor such as transport of seedlings, which imposes a heavy physical burden on workers. is there.

[0003] In order to improve such severe working conditions, research on cultivation techniques, improvement and development of cultivation containers, and the like have been carried out. It has been implemented.

The present applicant has also developed a cultivation container for cultivation of strawberries and leafy vegetables, which requires a small amount of cultivation soil and has good root growth, and also has an apparatus for holding this cultivation container and watering. Auxiliary tools suitable for fertilizer and fertilization were developed (Jitsuhei 6
-16495). FIG. 7 is a perspective view showing a state where the cultivation container in which the auxiliary tool is set is held by a holding device.

In FIG. 7, reference numeral 80 denotes a holding device; 81, a frame of the holding device 80;
Reference numeral 91 denotes a tapered cylindrical cultivation container, and reference numeral 92 denotes an auxiliary tool for watering and fertilizing. Thus, the cultivation container 91 is held in the holding device 8.
By keeping it at 0, the efficiency of cultivation work is improved and working conditions are improved.

On the other hand, as means for holding the cultivation container at a position higher than the ground, various other means are conceivable.
The present applicant has developed a means for suspending a cultivation container having a shape in which a plurality of container bodies are connected by a connecting member by suspending the cultivation container on a gantry, and has disclosed it in Japanese Patent Application Laid-Open No. 8-298870.

FIG. 8 is a perspective view showing an example of the cultivation apparatus according to the patent application. In the cultivation container 95, a part of the upper end of ten synthetic resin container bodies 96 is continuously formed. Thus, container body groups 97a and 97b in which ten container bodies 96 are linearly connected are formed, and the upper portions of the container body groups 97a and 97b are connected by a connecting member 98.

Each of the container bodies 96 has a circular cross section,
It is a tapered cylindrical container. The connecting member 98 is formed integrally with the container body groups 97a and 97b so as to extend from one side of the upper end flange of the container body groups 97a and 97b, and is adapted to the shape of the locking frame 99 of the holding device. hand,
It is formed in a square shape bent upward.

This cultivation apparatus can be applied to a case where it is permissible to dispose the cultivation containers in close proximity, and a large number of conventional cultivation containers can be placed at one locking position by one locking operation. Since the individual pieces can be locked, there is an advantage that the efficiency of the locking operation of the cultivation container can be improved.

[0010]

In the case of a conventional cultivation apparatus, regardless of whether the cultivation container is a single container or a connected container, the filling operation of the cultivation soil into the container body is performed for each container body. Because of the necessity, when the cultivation scale is large and there are many container bodies, a large amount of time and labor is required for the filling operation.

[0011] Further, in order to hold the cultivation container on the ground, a large number of locking frames must be installed in addition to the columns as the holding device. Is high. Further, in order to lock the cultivation container to the holding device, a locking piece or the like must be formed on the cultivation container itself, which increases the manufacturing cost of the cultivation container. In addition, since a large installation space is required as compared with a part which actually contributes to cultivation, the number of cultivation per unit area is small.

[0012] Further, since it takes time to attach and remove the cultivation container to and from the holding device, when using a large number of cultivation containers, these operations take a long time,
It is a heavy burden for the workers.

On the other hand, when growing strawberries and leafy vegetables,
Extending the roots of the plant to the deepest possible position in the soil improves nutrient absorption and improves the growth state.
The yield can be increased. However, in the case of soil cultivation, generally, a portion of 30 cm to 40 cm from the ground surface is cultivated, but since the ground thereunder is in a very hard state, the roots cannot extend below this. The tendency to expand in the lateral direction is large. Therefore, not only the absorption of nutrients from the roots is deteriorated, but also the roots extending laterally are entangled with each other, thereby inhibiting the elongation, thereby adversely affecting the growth of the plant.

On a hard ground portion, useful organisms such as earthworms cannot survive, and the supply of oxygen and the like becomes insufficient. This is a factor that hinders the growth of plants. In recent years, mechanization of agricultural work has progressed, and the use of heavy agricultural machinery has increased, so that the solidification of the ground has progressed more and more.

In order to cope with such a situation, in the cultivation containers 91 and 95, it is possible to increase the length in the vertical direction so that the roots of the plant can be extended to a deep position in the cultivation. Filling and discharging work becomes extremely difficult and the size of the holding device increases,
Lose practicality.

In the cultivation of strawberries and leafy vegetables, temperature control is extremely important. However, in the case of an erect cultivation apparatus, the influence of temperature changes is set because the cultivation soil is installed at a position higher than the ground. Therefore, more accurate temperature control is required as compared with soil cultivation.

In the case of elevated cultivation in a house, it is relatively easy to maintain the target temperature by controlling the temperature in the house. However, when the house volume is increased as in a large house, heating is not possible. There is a problem that the device becomes large-scale and the energy consumption increases.

On the other hand, in the case of elevated cultivation in the open ground, the outer periphery of the cultivation container and the holding device is covered with a vinyl sheet or the like,
Furthermore, temperature control is performed by installing a water storage duct or hot water pipe on the ground, etc.In such a method, it is impossible to maintain the temperature of the cultivation container installed on the ground within a range of several degrees Celsius. Have difficulty.

Therefore, the problem to be solved by the present invention is that standing work is possible, and filling and discharging work of cultivated soil is easy.
An object of the present invention is to provide an elevated cultivation apparatus capable of reducing the amount of soil, water, fertilizer, and the like used.

[0020]

Means for Solving the Problems In order to solve the above problems, the present invention relates to an elevated cultivation apparatus for cultivating plants by filling cultivation soil into a cultivation soil storage unit installed on the ground surface,
It is characterized by comprising a cultivated soil storage part formed by opposing a plurality of plate members, and holding means for holding the cultivated soil storage part in an inclined state on the ground surface.

In the elevated cultivation apparatus of the present invention, the cultivation soil storage unit is located above the ground surface, so that it is possible to perform a standing operation, and the cultivation soil only needs to be filled in the cultivation soil storage unit. The amount of cultivated soil used is smaller than in soil cultivation that forms ridges. Since the cultivated soil storage section is formed by facing a plurality of plate members and has a shape that is continuous in the lateral direction, the filling and discharging of the cultivated soil is easy. In addition, a large installation space is not required, and the device can be installed in a space similar to a conventional ridge.

In this case, the width of the cultivated soil accommodating portion formed between the opposed plate materials is determined according to the plant to be cultivated.
For example, in the case of a strawberry, if it is about 10 mm to 50 mm, the growing state is good, and it has been found that a sufficient yield can be obtained.

Further, since the cultivated soil storage section is held in an inclined state on the ground surface, the growing state of the plant to be cultivated is activated, and the yield can be increased. Hereinafter, the reason will be described using strawberry as an example.

The root of the strawberry planted in the cultivation soil filled in the cultivation soil storage unit tends to grow downward. However, since the strawberry seedling is held in an inclined state, the generation of new roots particularly from the crown portion is caused. Has the property of becoming popular. That is,
In strawberry seedlings, the emergence of new roots from the crown part is promoted more than the existing roots grow, and these new roots grow into the cultivated soil and take root well, so the subsequent growth state Be activated. In addition, the generation of many new roots from the crown portion promotes an increase in the number of flowers, so that the yield can be increased.

Furthermore, in the case of strawberries, since the runner has the property of extending in the direction in which the crown portion is inclined, the growth direction of the runner can be appropriately guided by holding the strawberry seedlings in an inclined state. There are benefits.

Here, the holding means for holding the cultivated soil storage section in an inclined state includes a column standing upright on the ground surface and a horizontal holding member locked to the column. A structure that detachably locks the upper part of the cultivation soil storage unit,
Alternatively, a structure in which one surface of the cultivated soil storage portion is locked to a horizontal holding member provided in a stepwise manner on the ground surface can be employed.

On the other hand, in the elevated cultivation apparatus of the present invention, the weight of the cultivated soil stored in the cultivated soil storage unit is supported by the ground surface by providing the cultivated soil storage unit with an opening that can be connected to the ground surface. Therefore, it is possible to reduce the load on the cultivation soil storage unit. It is also possible to extend the roots of the plant into the ground by passing through the opening, which is effective for discharging excess water and the like in the cultivation soil storage unit.

Further, by forming a through hole for plant cultivation in the plate material constituting the cultivated soil accommodating portion, the plant can be cultivated even in the cultivated soil exposed at the through hole portion. The cultivation number per unit area can be greatly increased while utilizing the function of the cultivated soil storage unit. In this case, the number, arrangement, and the like of the through holes formed in the plate material are not particularly limited, and can be determined according to the plant to be cultivated.

Here, by providing the cultivation soil leakage means in the through hole, it is possible to prevent the cultivation soil in the cultivation soil accommodating portion from leaking from the through hole even during the cultivation period.

In this case, a leakage prevention member having a U-shaped cross section which can be attached to and detached from the through hole can be used as the soil leakage prevention means. By using such a leakage prevention member, soil leakage can be effectively prevented without inhibiting the growth of plants or obstructing various operations. In addition, since the leakage prevention member is detachable, it can be removed in the case of seedling planting operation or storage.

On the other hand, in the elevated cultivation apparatus according to the present invention, the holding mechanism is shared and the holding mechanism is simplified by arranging the cultivation soil receiving sections on the ground surface so as to face each other in an inverted V-shape. And stability is improved. Further, the number of cultivated trees per unit area can be increased.

In addition, by making the inclination angle of the cultivation soil accommodating portion changeable, it is possible to install the cultivation area in accordance with the state of sunshine, so that the growth state of the plant is improved.

Further, by providing a temperature adjusting means for heating or cooling the cultivated soil storage section, temperature control can be performed according to the climate of the cultivation area, the plant to be cultivated, and the like.

In this case, by using, as the temperature adjusting means, a tubular body provided below the cultivated soil storage section and a heated or cooled fluid sent into the tubular body, the cultivated soil storage section is formed. Since heating or cooling can be performed efficiently, accurate temperature management can be performed.

Various materials can be used for the plate material constituting the cultivated soil storage section. However, by using a synthetic resin plate material, sufficient strength is provided, and the material is deteriorated by fertilizers, agricultural chemicals, chemicals, and the like. It is possible to form a buried soil accommodating portion having excellent durability without being deformed. In this case, an acrylic plate or the like can be used, but by using a plate made of a foamed synthetic resin such as foamed polystyrene, the weight can be reduced.
