Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a pot used for hydroponic cultivation.

(Conventional technology) Hydroponic cultivation is an industrial agriculture based on science and technology, breaking away from the traditional soil-based agriculture centered on empirical technology. It is an industrial production method that eliminates the influence of the environment, provides an optimal environment for plant growth, and maximizes the original properties of plants.
Hydroponic cultivation equipment used for such hydroponic cultivation is rapidly becoming popular among farmers and companies aiming to diversify, as it generally has high productivity of cultivated crops and has a wide selection of cultivated crops. .

As an example of conventional hydroponic cultivation, plants are planted in a medium made of urethane or the like in a pot, placed in the upper part of a cultivation tank, roots are allowed to grow through the peripheral and bottom walls of the pot, and then placed inside the cultivation tank. Vegetables, fruits, flowers, etc. were cultivated by immersing plants in a culture solution and supplying nutrients and oxygen necessary for the plants to the culture solution.

Pots used in such hydroponic cultivation are, for example, porous pots that are permeable to water and air permeable, and have a large number of pores that are large enough to prevent the roots of plants sown in the medium from penetrating and being exposed outside the pot. It was known that it was composed of a body (Japanese Patent Application Laid-Open No. 62-272923).

(Problem to be solved by the invention) However, in the case of the pot disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 62-272923, the roots of the plant are housed in the pot, so that sufficient root diffusion is not possible. Not obtained,
As a result, water permeability, air permeability, and oxygen supply are insufficient, leading to problems such as bacterial growth and disease outbreaks. In addition, this pot is made of a porous material that has many pores that are too large for the roots of the plant to penetrate outside the pot, so it is easily clogged with dust, etc., and has a structure that does not allow sufficient water flow and ventilation to the roots. I have the above problem.

In view of these conventional problems, the present invention is an attempt to solve these problems by diffusing the growing roots of plants downward to ensure sufficient water flow and ventilation to the roots. A pot for hydroponic cultivation that can be easily replanted without damaging the roots, and also allows plants such as orchids grown hydroponically to be sold as potted plants through distribution channels. The purpose is to provide the following.

(Means for Solving the Problems) The present invention has been made in order to solve the above-mentioned conventional problems and achieve the intended purpose.
The gist of the system is to have a cylindrical upper pot and a lower pot each having a plurality of window holes in the peripheral wall, and to have water permeability on the peripheral surface of the upper pot, A net-like body having a large number of holes large enough to prevent the roots of the cultivated plants from penetrating outside the peripheral wall is provided, and a root guide plate is provided in the lower pot to guide the roots of the plants inward. The present invention resides in a pot for hydroponic cultivation characterized by the following.

In addition to supporting a culture medium on the upper part of the upper pot,
Preferably, the support is provided with an opening through which the roots of the plant pass. Further, it is preferable that at least one opening body having a large number of openings large enough for plant roots to pass through is provided in the upper pot or the lower pot. Furthermore, it is preferable that the upper bowl and the lower bowl are detachable by a connecting mechanism.
Furthermore, it is preferable that supports for supporting the pillars are provided on the outer peripheral surfaces of the upper pot and the lower pot.

(Function) According to the hydroponic cultivation pot of the present invention, the roots of plants to be hydroponically cultivated in the upper pot do not protrude outside the peripheral wall due to the net-like structure provided on the peripheral surface of the peripheral wall, but are directed downward. The roots that grow downward are
In the lower pot, the roots will be guided inward by the root guide plate and then spread downward, so the roots should be densely packed and stabilized, and the roots should have sufficient water flow and ventilation. Moreover, when replanting, it is now possible to easily replant without damaging the roots.

Furthermore, if a support body is provided above the upper pot that supports the medium and has an opening through which the roots of the plant pass, the medium can be easily supported in the upper pot. Furthermore, if at least one opening body having a large number of openings large enough for plant roots to pass through is provided in the upper pot or the lower pot, the distance between the growing roots can be maintained at a good distance. Furthermore, if the upper pot and the lower pot are made detachable by a connecting mechanism,
At the stage of young plants, only the upper pot can be used for hydroponic cultivation, and when the plants have grown, the lower pot can be connected to the upper pot for hydroponic cultivation. Furthermore, by providing supports for supporting the supports on the outer peripheral surfaces of the upper and lower pots, the supports can be easily supported around the pots, and seedling splints and the like can be attached.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

When using pot A constructed in this way,
First, as shown in FIG. 5, only the upper pot 10 is used, and a medium 60 made of rock wool, urethane, etc. for holding plant seeds or seedlings is supported on a support 17. Note that at this time, a holder for holding the culture medium 60 may be provided at the opening edge of the upper pot 10. The pot A in which the seeds or seedlings are supported in the medium 60 in this way is immersed in the culture solution 71 of the cultivation tank 70, and the seeds or seedlings are germinated and grown by conventional methods. After that, when the roots of the plant grow, connect the lower pots 20 as shown in FIG.
It also promotes plant growth. In this case, the roots Pa of the plant P extending downward cannot be exposed outside the peripheral wall 11 within the upper pot 10 due to the net-like body 13, and only extend downward. The roots Pa extending downward are guided inside the lower pot 20 from the root guiding plate 30, and further downward or through the window holes 23, 23.
It will continue to grow.

Therefore, the roots of the plants hydroponically cultivated in the pot A of this embodiment can be made to grow only downward by the net-like body 13, and the roots of the plants to be grown downward are once prevented by the root guide plate 30. Since it can be made dense and then diffused downward, it is possible to stabilize the roots of plants growing downward, and to ensure sufficient water flow and aeration to the roots, as well as to prevent the culture solution or air from flowing. Good circulation prevents bacterial growth and
Disease outbreaks were effectively prevented, and when repotting, the roots could be easily removed from the pot without being cut. Furthermore, when a plant such as an orchid is hydroponically cultivated using the pot of this example, it becomes possible to ship the plant as a potted plant as it is. In addition, when finally shipping as a potted plant, the pot of this example in which a plant such as an orchid grows is used as an inner container, and an outer container is attached to the inner container that can be detachably stored inside the pot. Once shipped, they can be handled in the same way as ordinary potted flowers in soil, and can even be used as ornamental pots.
