  The existing Vacin-Went medium described above has a certain effect on the growth of Psigmorchis Pusila, but the formation of spikes was about once a year even if other conditions were improved. . Accordingly, one object of the present invention is to provide a medium that can be flowered about once a month throughout the year by storing it in a suitable environment.

  Moreover, since patent document 1 is a container for seed propagation instead of ornamental use and uses the soil, watering becomes indispensable. Another object of the present invention is to provide an orchid viewing system that can enjoy flowers for a long period of time without any management such as watering.

  Furthermore, in Patent Document 2, the upper case and the lower case are sealed using packing, but there is no possibility of a pressure difference between the inside and outside of the container because there is no vent hole or the like. Moreover, since the configuration is complicated, there is a drawback that the production of the growing apparatus itself is expensive. Another object of the present invention is to provide a vent on the lid so as not to cause a pressure difference between the inside and outside of the container, and to dispose germs by disposing a breathable filler containing a bactericidal agent in the vent. The object of the present invention is to provide a run appreciation system capable of suppressing invasion as much as possible and maintaining a sterile condition for a long time.

  In order to solve the above problems, the medium for orchid cultivation according to the present invention is characterized in that, in the Vacin-Went standard medium, at least the total nitrogen, phosphorus and potassium concentrations are reduced. In particular, among the nutrients contained in the Vacin-Went standard medium, it is preferable that at least the total nitrogen, phosphorus and potassium concentrations are 30 to 70% with respect to the standard concentrations. The medium is preferably in a semi-solid gel form. The culture medium for orchid cultivation according to the present invention is particularly effective for generating spikes of Psigmorchis Pusilla.

  In order to solve the above another problem, in the orchid appreciation system according to the present invention, a transparent container that can be sealed, the orchid cultivation medium according to claim 3 placed on the bottom of the container, and an orchid planted in the medium And a hermetic lid, wherein the hermetic lid is air permeable to maintain the same air pressure inside and outside the container.

  In the above run appreciation system, it is desirable that the sealing lid has at least one through hole, and a breathable filler is disposed in the through hole. The breathable filler is preferably a cotton-like material. It is more effective if a disinfectant is filled in the filler. Such a run appreciation system according to the present invention is particularly suitable for Psigmorchis Pusilla.

  The medium for orchid cultivation according to the present invention is not only suitable for the growth of orchid plants, especially Psigmorchis Pusilla, but also has a special effect on the production of spikes, and is maintained almost every month by holding it in a suitable environment. Can be formed.

  In addition, in the orchid appreciation system according to the present invention, it is possible to clearly observe the internal orchids by using a transparent container, and it is possible to suppress the invasion of various bacteria by maintaining a state close to the hermetic state and to grow the orchids for a long time. The environment can be maintained well. In addition, by using a semi-solid medium, the medium does not move even if the container is tilted, so that it is possible to prevent a load on the root of the orchid.

  Hereinafter, the present invention will be described in detail. As a medium for orchid cultivation, Vacin-Went medium is used as a standard (Comparative Example 1), and a medium with a reduced total nitrogen amount, phosphorus and potassium concentration is prepared with respect to this standard medium, and Psigmorchis Pusilla is grown. Then, the breeding situation and the number of flower spikes were investigated. The results are shown in Table 1. The Vacin-Went medium (Comparative Example 1) is effective for the growth of many orchids, but the nutrients necessary for the formation of flower spikes vary greatly depending on the species. As can be seen from Table 1, the inventor has found that, when the amount of total nitrogen, phosphorus, and potassium is 30-70% of the concentration of Vacin-Went medium, the formation of spikes of Psigmorchis Pusilla Was confirmed to be the most prominent.

  Next, a run appreciation system according to the present invention using the above medium will be described. FIG. 1 shows an embodiment of a run appreciation system according to the present invention. A medium 2 in which nutrients having the composition according to the present invention are solidified into a semi-solid gel using agar or the like is placed in a bottle-shaped transparent container 3, and a sigmorkis pusilla (Psigmorchis Pusilla) 1 grown to about 0.5 cm is placed there. Plant an individual. The opening of the container 3 is sealed with a sealing lid 4 such as cork. The sealing lid 4 is provided with at least one through hole 5 through which air can flow. However, in order to prevent various germs from entering the inside of the container, the through-hole 5 is filled with a filler 6 such as absorbent cotton soaked with a disinfectant.

  With the above configuration, a semi-enclosed orchid appreciation system can be provided. According to this system, orchids are planted in a medium in which nutrients are hardened in a gel form, and the medium is in a gel form, so the evaporation of moisture is extremely high. Because there are few, you can appreciate the run for 6 months to 1 year or more without taking care of watering. In addition, the medium used for this is according to the present invention. In particular, since it is an effective ingredient for the formation of spikes of Psigmorchis psilla (Psigmorchis Pusilla), it is possible to enjoy the formation of new spikes almost every month if placed in an appropriate environment. .

  In the above-mentioned orchid appreciation system, it is sufficient that at least the main part of the container is transparent. Therefore, parts that do not interfere with the appreciation, such as the bottom and the vicinity of the opening, do not necessarily have to be transparent. The sealing lid is preferably made of rubber, but is not limited to this, and other materials such as plastic and cork can be used. Furthermore, the filler in the through hole is not limited to absorbent cotton, and other materials can be used. As for the disinfectant, since it does not directly contact the run, a general disinfectant available at a pharmacy or the like can be used.

  As described above, the orchid cultivation medium of the present invention is not only suitable for the growth of orchid plants, particularly Psigmorchis Pusila, but also has a special effect on the production of spikes and is maintained in a suitable environment. This makes it possible to form flower spikes almost every month. In addition, in the orchid appreciation system according to the present invention, it is possible to clearly observe the internal orchids by using a transparent container, and it is possible to suppress the invasion of various bacteria by maintaining a state close to the hermetic state and to grow the orchids for a long time. The environment can be maintained well. Therefore, it is possible to enjoy the flowering of orchids for a long time without taking time and effort, which is extremely useful as a gardening appreciation system.

It is a figure which shows the Example of the run appreciation system by this invention.
