DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant cultivation structure and a device therefor, and more particularly to a plant cultivation structure and a plant cultivation device for cultivating plants efficiently and without causing disease.

[0002]

2. Description of the Related Art In recent years,
The rising costs of land, labor and other costs have created conflicting demands for stable supplies of crops and cost reductions. In order to satisfy such demands, it is necessary to effectively use land and people and increase the yield efficiently without increasing the planted area. However, since agricultural products are usually produced under natural conditions, they are greatly affected by weather conditions such as temperature. For example, lack of sunshine and a decrease in temperature are accompanied by a decrease in the temperature of the ground, resulting in crop damage such as poor growth. In addition, when plants such as tomatoes are repeatedly produced on the same land, there is a problem that not only does the crop yield not increase due to crop rotation failure, but also crops of poor quality due to the occurrence of diseases and the like.

[0003] In order to prevent cold damage among such problems, hitherto, in house cultivation and the like, the room temperature has been raised by burning heavy oil or the like or turning on an electric light to prevent the cool damage. However, it is necessary to use a large amount of energy such as heavy oil, which not only increases the cost but also causes air pollution and is not preferable from the viewpoint of resource protection.

[0004] In order to eliminate crop rotation disorders, it is necessary to produce different types of crops at certain times without repeatedly producing the same types of crops on the same land. However,
Because the production time, such as the time of planting the crop, differs depending on the type, if the combination is poor, fallow must be fallowed for at least about half a year, which has been a cause of poor productivity.

[0005] Furthermore, spraying water or liquid fertilizer is a laborious and heavy labor. For example, in the case of liquid fertilizer or the like, if liquid fertilizer is directly attached to the surface of the crop, the surface may be discolored. Need to be sprayed at the base. However, this was a tricky and time-consuming process.

The inventors of the present invention have conducted intensive studies to solve these problems, and as a result, have arrived at the present invention.

Has a saucer shape as a whole, for example, and is configured such that the fixed culture medium 14 placed on the floor portion 24 does not shift in position. A long groove 28 is provided in the floor portion 24 of the container 12, and a pipe 22 for adjusting the temperature is provided in the long groove 28, and hot or cold water, or hot or cold air is passed through the pipe 22 for heating. Or, it is configured to be able to cool.

[0027] Here, the foam constituting the receiving container 12 is foamed to have, for example foamed polystyrene resin, the foamed polyolefin-based resin such as foamed polyethylene or foamed polypropylene, so as to foam the copolymer of styrene and ethylene or propylene A resin or the like is used, more preferably formed by a bead molding method.
It is integrally formed by combining a seed or materials, different
It may be constituted by being combined with the body . In particular, among these, materials having excellent pressure resistance, durability, heat insulation, and the like are preferable, and can withstand the weight of the fixed medium 14 placed on the container 12 for a long time, and have a low or high temperature in winter or summer. Those having excellent heat insulating properties to protect plants from the heat are preferred.

On the upper surface of the container 12, a fixed medium 14 covered with a water-impermeable sheet 16 is placed. The fixed medium 14 is composed of a lower fixed medium 30, an upper fixed medium 32 and a seedling-fixed medium 34. It is configured. Fixed medium 14
Is a solidified or solidified fibrous component
In particular, it is also possible to use, as the fixed medium 14, a solid medium obtained by mixing wood wool as a main raw material, suitably mixing rock wool, nonwoven fabric, felt or other fibrous components. The composition of the fiber component of the lower fixed medium 30 constituting the fixed medium 14 is set so that the plant 36 grows with roots. Further, the upper fixed medium 32 is provided with a plurality of recessed portions 38, and is configured to form the recessed portion 38 in combination with the lower fixed medium 30. This upper fixed medium 32 is not intended to grow the roots of the plant 36, and the lower fixed medium 30
The composition of the fiber component is set so as to keep the water stable and retain water. In addition, fixed seedling culture medium 3

Here, the wood fiber is preferably a fiber obtained by mixing hinoki bark and cedar bark at a predetermined ratio, respectively. The wood fiber is used as a main raw material, and rock wool, resin fiber and the like are used. A mixture of tree chips and bark fibers is used. The fibers consisting of hinoki bark and cedar bark are processed so as not to impair the active ingredients such as hinokitiol originally possessed by hinoki and cedar. The disease of the plant 36 is prevented, and at the same time, pests and the like attached to the plant 36 can be eliminated. Therefore, since insects do not occur in the long groove 28 of the container 24 or the fixed medium 14 or the insects do not come to the planted plant 36, the plant 36 rarely becomes sick or eaten by pests. It is preferable that the fixed medium 14 mainly composed of the hinoki bark and the cedar bark is covered and fixed by a binder made of resin or the like or resin fibers so as not to be dispersed. The fixed medium 14 having such a configuration is excellent in water retention, air permeability, water storage, and heat retention as compared with an artificial fixed medium such as ordinary soil or rock wool, and the thickness of the fixed medium 14 is reduced. It does not hinder the growth of plants such as lawns and flowers.
