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 cultivating fruit vegetables, leafy vegetables, flowers, root vegetables and the like at a position higher than the ground surface.

[0002]

2. Description of the Related Art When cultivating fruit vegetables, leafy vegetables, flowers or root crops, a so-called soil cultivation method is employed in which seedlings are planted and grown along ridges formed on the ground of the cultivation area. I have. In soil cultivation, a series of operations from raising seedlings to harvesting are often performed in a crouching or crouching position.Especially in the case of strawberries etc., in the planting work of seedlings, heavy labor such as transport of seedlings is involved. However, the physical burden on the worker is very large.

[0003] In order to improve such severe working conditions, development of cultivation containers in which workers can work in a standing posture and research on new cultivation techniques have been carried out. A cultivation method called setting cultivation is being implemented.

[0004] The present applicant has also developed a cultivation container for strawberry and the like which requires a small amount of cultivation soil and has good root growth, and this is disclosed in Japanese Utility Model Laid-Open No. 6-34437. In addition, a device for holding the cultivation container and an auxiliary tool suitable for watering and fertilizing have been developed.

Since the standing work can be performed, the working conditions can be improved and the cultivation work can be made more efficient.

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

FIG. 9 is a perspective view showing an example of the cultivation apparatus according to the above publication. The cultivation container 95 is formed by continuously forming a part of the upper end of a synthetic resin container body 96.
Container body groups 97a and 97b having a shape in which ten container bodies are connected in a straight line form, and these container body groups 9a and 97b are formed.
A structure is provided in which the upper portions of 7a and 97b are connected by a connecting member 98.

[0008] By using this cultivation apparatus, it is possible to perform a standing operation, and a large number of conventional cultivation containers can be locked to the frame 99 by a single locking operation.
The work of locking the cultivation container can be made more efficient.

[0009]

In the case of a conventional elevated cultivation apparatus, regardless of whether the cultivation container is a single container or a continuous container, it is necessary to perform the operation of filling the container with the cultivation soil for each container. For this reason, in large-scale cultivation using a large number of cultivation containers, a large amount of time and labor is required for installation work and soil filling work.

Further, in the case of the conventional elevated cultivation apparatus, the cultivation containers have independent structures, have a large area to be exposed to the outside air, and are easily affected by the surrounding temperature, and therefore have a low heat retaining function or a cold retaining function. For this reason, during the cultivation period, heating or cooling is often performed, but it is necessary to provide a large-scale temperature control mechanism such as a hot air duct along the arrangement direction of the cultivation containers, resulting in an increase in the size of the apparatus. I have.

The means can be diversified, and workability in the case of providing a temperature control pipe or the like in the cavity is improved. The opening communicating with the cavity is desirably provided on the lower surface portion of the cultivation container, whereby the temperature can be efficiently adjusted by hot air or the like.

On the other hand, in the elevated cultivation apparatus of the present invention, since the cultivation soil container is formed of a foamed synthetic resin, the heat insulating property is enhanced, and the heat retaining and cooling functions are improved. Can manage. In addition, since foamed synthetic resin is excellent in corrosion resistance, during the cultivation period, it is deteriorated by chemicals such as pesticides and fertilizers or sunlight,
It can be used for a long time without deformation.

[0021] In this case, by using expanded polystyrene as the expanded synthetic resin, it is possible to form a lightweight soil storage container having excellent transportability. In addition, since foamed polystyrene has good moldability, a cultivated soil container having a shape and a structure suitable for cultivation conditions can be easily formed.

Further, in the elevated cultivation apparatus of the present invention, a shelf-like body placed on the ground can be adopted as the holding means for the cultivation container. By adopting such a structure, the buried soil container can be held at a height suitable for standing work, and the stability is also good. Further, since a space is formed between the ground and the soil cultivation container, adverse effects of the temperature and humidity of the ground on the soil cultivation container can be reduced. Further, the space between the ground and the soil cultivation container can be used as a space for arranging piping and ducts for temperature control of the soil cultivation container.
