Description

  The present invention relates to a plant cultivation container suitable for plant growth and a plant cultivation method using the same.

  Many containers for plant cultivation are opaque and block the entrance of light from the container walls. Therefore, if there is little soil and the medium (soil, bark, etc.) is located below the entrance of the container, the seedlings of the plant planted there will penetrate deeply into the container and will be covered with the container wall. On the other hand, if there is a lot of medium and it is close to the entrance of the container, the seedlings of the plant will protrude from the container, and although sufficient sunshine will be obtained, moisturization near the seedlings will deteriorate, making it an unfavorable environment for seedling growth . Therefore, it is difficult to adjust the filling amount of the medium in the container, and depending on the experience, there are many cases where container cultivation fails. Moreover, although the transparent container for plant cultivation also exists, in that case, sunlight will hit a plant root, and root growth will be inhibited. In addition, even in the case of wet cultivation, if there is little water in which the plant roots are placed in the opaque container, the sunlight is similarly insufficient, and in the transparent container, the adverse effect on the root growth by sunlight becomes more serious.

  Orchidaceae plants are cultivated by placing seedlings germinated after sowing and seedlings obtained by aseptically growing plant meristems by biotechnology in cultivation containers. When wet cultivation is carried out, the freshness of water greatly affects and root rot due to lack of freshness is likely to occur, so it is necessary to provide large facilities such as a pool. May cause large-scale disease of seedlings. Therefore, even in the cultivation of orchidaceae seedlings, moss cultivation is carried out by using containers such as polypots, plastic pots, and jiffy pots, and cultivating the roots in moss. Therefore, problems such as insufficient sunshine, poor moisture retention, and poor root growth due to transparent containers occur.

In addition, although the planter for wet cultivation is disclosed as a container relevant to this invention (for example, refer patent document 1), it is a device only regarding adjustment of a water level, and like a container concerning this invention, it is a plant. It does not prepare the growth environment.
Registered Utility Model No. 3025167 (see FIG. 1)

  Therefore, the present invention is such that the container has good moisture retention during plant cultivation, and the above-ground stem parts (leaves, stems) of the plant are easily exposed to light, and the root part is prevented from receiving light and its growth is not hindered. It is another object of the present invention to provide a plant cultivation container suitable for plant growth and a plant cultivation method using the same.

  As a result of earnest research to achieve the above-mentioned purpose, a part of the container for plant cultivation is a transparent wall and the other part is an opaque wall that does not transmit light, and the opaque wall part (meaning the inside of the container surrounded by the opaque wall) If the roots of the plant are placed on the transparent wall part (meaning the inside of the container surrounded by the transparent wall. The same applies hereinafter), the other leaves and stems will be placed. The present invention was completed by finding that it grows well.

  That is, the first invention of the present invention is a plant cultivation container characterized in that the upper part of the container wall is a transparent wall and the other part is an opaque wall.

  In the present invention, the opaque wall may be formed so that the wall portion does not transmit light. For example, a part of the transparent container wall is coated with black paint that does not transmit light or is coated with a black film. Is achieved by performing Of course, the wall itself may be an opaque wall (for example, a black film wall, a black plastic wall, a ceramic wall, etc.).

  In addition, since such a container only needs to be configured so that the upper part is transparent and the other part is opaque, for example, a double container is used, and the above structure (upper part is combined with a transparent container and an opaque container). May be transparent and other parts may be opaque).

  Of the present invention, the second invention is the plant cultivation according to the first invention, wherein the opaque wall is formed from the bottom of the container to a height of ¼ to ¾ of the total container height. Container. If it exceeds 3/4, the volume of the transparent wall portion may be small, which may lead to insufficient sunshine or poor moisture retention, and if it is less than 1/4, the volume of the opaque wall portion is small, leading to poor root growth environment. Because there is a fear.

  The height of the opaque wall is preferably 1/3 to 2/3 of the total container height, more preferably about 1/2.

  3rd invention among this invention is a container for plant cultivation of the said 1st invention or 2nd invention characterized by using the said container for the hydroponic cultivation or bark cultivation of a Orchidaceae plant. Here, wet cultivation refers to a cultivation method in which plants are grown using water (mostly an aqueous solution of fertilizer) without using soil, and bark cultivation refers to a cultivation method in which bark (bark) is used without using soil. . The container can also be used for cultivating moss, but cultivating moss is not only troublesome because it wraps the root with moss, but it is easy to damage the roots, so it is used for hydroponics and bark cultivation as in the present invention. More preferred.

  A fourth aspect of the present invention is a plant cultivation method in which the plant cultivation container according to the first, second or third aspect of the invention is used, and a plant root portion is disposed on an opaque wall portion. Compost or water containing soil, bark, etc. alone or as a main body is put in the opaque wall part, the roots of the plant are arranged there, and the ground stem part is arranged in the transparent wall part.

  5th invention among this invention is the cultivation method of the plant of 4th invention which cultivates a Orchidaceae plant using negative ion water. Negative ion water is considered to prevent the invasion of germs into the field plant, and has the effect of improving its growth in combination with the following effects of the container according to the present invention.

(1) According to the plant cultivation container or the plant cultivation method according to the present invention, the presence of the transparent wall suppresses the evaporation of moisture and ensures light transmission, and the presence of the opaque wall allows light to enter. Since it is prevented and root growth is not inhibited, a favorable humidity environment and light environment are provided for plant growth. As a result, the growth of the plant is improved as compared with the case where a conventional container such as a pot is used. That is, for example, plants often wilt seedlings when using conventional containers, but most seedlings grow freshly and freshly when using this container.
(2) According to the container or the plant cultivation method according to the present invention, the height of the opaque part where the root part of the plant is arranged in advance can be clearly specified according to the kind of the plant. On the other hand, there is an advantage that even an amateur who has no training experience can fill the medium and water without mistakes.
(3) The container according to the present invention is suitable for cultivation of orchids, foliage plants, cactuses, succulents, flowers, vegetables, moss, and the like, and can be used as a teaching material because the growth of roots can be easily observed. Furthermore, when the container according to the present invention is a plastic container, it is inexpensive and convenient to carry, and can also be used as a small container for raising insects such as beetles, small fish, and pencil stands.

  Although the form for implementing this invention is as follows, these are only examples of the form for implementing this invention, and this invention is not limited to these embodiment.

  FIG. 1 is a perspective view of a plant cultivation container according to the present invention, in which an inner container 1 is a black polypropylene container, and an outer container 2 is a polystyrene transparent container. As shown in FIG. 1, this container is a double container, but the container as a whole becomes an opaque wall because its lower half is a black inner container 1, and its upper half is a transparent outer. Because of the container 2, it is a transparent wall that allows light to pass through. The individual containers of the double container can be easily obtained by ordinary injection molding using a mold, compression molding or the like. FIG. 2 is a front view of the container of FIG. 1, and FIG. 3 is a front view of a state in which plant seedlings (one strain) are placed in the container.

  FIG. 4 shows a container skeleton according to another embodiment of the present invention, and the container skeleton (made of plastic) can be easily obtained by ordinary injection molding. A container (FIG. 5) according to the present invention can be easily obtained by winding a transparent film on the upper half of the skeleton and a black film on the lower half and bonding them to the container skeleton. Of course, the whole container or the upper half is wrapped with a transparent film, and then the lower half of the container is wrapped with a black film, or the lower half of the container is wrapped with a black film, and then the whole container or the upper half is wrapped with a transparent film, etc. Forms are also conceivable.

  Double containers (eg, FIG. 1) can be separated from each other as compared to single containers (eg, FIG. 5), so if it is necessary to occasionally apply wind depending on the type and growth of plant seedlings, the inner container The seedling can be easily blown with wind, and if it is necessary to transfer the inner container to another container, it can be easily implemented.

  The cultivation method according to the present invention fills the inner container 1 of the double container shown in FIG. 1 with soil in the case of soil cultivation, water in the case of hydroponics, bark in the case of bark cultivation, The root part of the plant seedling should be embedded and cultivated as shown in FIG. Then, the leaves of the seedling are sufficiently irradiated with sunlight from the transparent wall 2a at the top of the transparent container 2, and the given water can prevent evaporation that diffuses in the lateral direction by the transparent wall 2. Therefore, the moisturizing state is improved, and light enters the root part by the opaque wall 1a, so that the root grows smoothly as in normal pot cultivation. Therefore, according to the cultivation method which concerns on this invention, compared with normal pot cultivation without a transparent wall, growth of a plant becomes favorable.

  For example, using a Cymbidium seedling taken out from the inside of a Mericlon flask (a seedling obtained by aseptically growing a Cymbidium meristem by biotechnology, the seedling length is about 10 cm), and using a black container 1 When using only (volume: about 0.5 liter) (corresponding to normal pot cultivation) and the double container according to the present invention (volume of transparent container 2: about 1 liter, volume of black inner container 1: about The case of using 0.5 liter) was compared by carrying out hydroponics or bark cultivation. The cultivation conditions are as follows. When only the black container 1 was used (Comparative Example) and when the double container was used (Example), the cultivation was performed under the same conditions except for the difference in the container.

  Hydroponics: In a state filled with negative ion water (Genki Water, manufactured by Nippon Kosen Research Co., Ltd.), 20 black symbium seedlings are placed in each of the 200 black containers 1, and one day without fertilizer. Cultivated for 2-3 months, adding water once. In this case, half of the 200 black containers 1 were cultivated in a single container (comparative example), and the remaining half 100 were cultivated in a transparent container 2 as a double container (example). In the case of a double container, a hole is made at the height of the black container on the side wall of the transparent container 2, and the water overflowing from the black container is discharged out of the hole. Aligned to the same size. These containers were placed in a glass greenhouse to adjust the temperature and humidity. The daytime temperature was 25 ° C., the night temperature was 22 ° C., and the humidity was 80% throughout the day and night. All light was irradiated with natural light.

  Bark cultivation: In a state filled with bark (bark for cymbidium, manufactured by Toyo Denka Kogyo Co., Ltd.), 20 black seedlings 1 were planted in each of the 200 black containers 1, and water was given once a day to give liquid fertilizer. (Hyponex, manufactured by Hyponex Japan) was cultivated for 2-3 months while giving it once every 7 to 10 days. Also in this case, 100 half of the 200 black containers 1 were grown in a single container (comparative example), and the other half 100 were grown in a transparent container 2 and grown as a double container (Example). . These containers were placed in a glass greenhouse and cultivated by adjusting the temperature, humidity, and light so that the conditions were the same as in hydroponics.

  As a result, in the case of the comparative example, in both hydroponics and bark cultivation, 20-30% of the seedlings were wilted and the rooting was not smooth and the seedlings were uneven, resulting in a significant reduction or loss in commercial value. However, in the case of the examples, both hydroponics and bark cultivation were high in commercial value because 95-100% of the seedlings were fine and the seedling sizes were uniform.

These are the perspective views of the container for plant cultivation of one embodiment which concerns on this invention. FIG. 2 is a front view of the container of FIG. 1. These are the front views of the state which put the plant seedling (one strain) in the container of FIG. These are perspective views which show the frame | skeleton of the container of other embodiment which concerns on this invention. FIG. 6 is a perspective view showing a container according to another embodiment of the present invention, in which a transparent film is wound around the upper half of the container skeleton of FIG. 4 and a black film is wound around the lower half, Bonded to the container skeleton.
