Description

The present invention relates to a plant cultivator, an ornamental plant using the plant cultivator, and a plant cultivation method.
More specifically, in a plant cultivator provided with an inner container and an outer container that receives a culture solution to be passed through the inner container, the plant can be cultivated for a long period of time even if the cultivator has the same size. Can be enjoyed for a long time in a limited space, such as at home or on a company desk, and the number of irrigation or watering (hereinafter referred to as irrigation) can be reduced. It relates to what I did.

In recent years, an ornamental plant planted in a simple cultivation container made of plastic or the like is placed on a desk at home or at a company and enjoyed. For example, Patent Literature 1 discloses this type of cultivation container.
Japanese Utility Model Publication No. 5-20545 (page 9, Fig. 1)

  According to patent document 1, a cultivation container is provided with an inner container and an outer container, and is used as follows. First, in a planting place for flowering trees, seedlings of flowering trees whose roots are wrapped with moss or soil are planted in the inner container. The inner container in which the seedling is planted is put in the outer container, and the protrusion on the support base of the outer container is inserted into the hole of the inner container. Before and after this, an appropriate amount of water-absorbing resin is put in an outer container, an appropriate amount of water is added to absorb water, and a lid is put on. Thereby, the action / effect of “the evaporation of water is suppressed by the lid and the number of times of water supply can be reduced” is described.

However, as a result of the inventor cultivating plants using the cultivation container described in Patent Document 1, it has been found that there are the following problems.
That is, the roots of the grown plant do not extend from the hole in the inner container to the water absorbent resin in the outer container, continue to grow in the inner container, and finally clog in the inner container and become deficient due to oxygen shortage. End up. Therefore, in order to cultivate a plant for a long period of time with a cultivation container of the same size, it is necessary to enlarge the inner container. For this purpose, the outer container that receives the inner container also becomes larger, and the entire cultivation container becomes larger. However, this is not suitable as a cultivation container placed in a limited space such as a home or office desk.

  In addition, although it is possible to make the outer container as small as possible and suppress the size of the entire cultivation container, the amount of water stored in the outer container decreases and the number of irrigation increases.

  The inner container contains a medium containing a gap through which air passes, such as moss and soil. For this reason, if water is added too much to the outer container and the water level rises, water will also penetrate into the moss and soil in the inner container up to the same water level, causing root rot in the inner container. Therefore, a lot of water cannot be given to the outer container at a time. For this reason, the number of times of watering inevitably increases.

  Therefore, for retailers who plant and sell plants in cultivation containers, it is necessary to frequently perform irrigation, which requires manpower. In addition, after purchase, if the irrigation is neglected for a long trip or the like, the plant will die.

  In order to solve the above-mentioned problems, the present inventor does not first extend the root of the plant grown in the inner container to the water absorbent resin in the outer container, and continues to grow in the inner container. Numerous experiments were repeated to investigate the cause of clogging and withering.

  As a result, the roots of plants rooted in a medium containing gaps through which air passes, such as moss and soil, are roots suitable for soil cultivation only, and the water-absorbent resin in the outer container that has absorbed the cultivation liquid Thus, it was found that the roots are not compatible with a medium that does not include a gap through which air passes.

  Therefore, instead of replanting the rooted plant into the inner container, by newly rooting the plant in the inner container that uses the water-absorbent resin that has absorbed the cultivation liquid as a medium, it does not include the gap through which the air passes. It has been found that roots suitable for the medium can be obtained, and as a result, it is possible to grow the roots in the inner container to the water absorbent resin in the outer container. In addition, the roots are suitable for hydroponics (water roots), and it has been found that the roots can grow not only with the water-absorbent resin but also with the cultivation liquid alone.

And further research on rooting the roots of the plant by sprouting into the water-absorbent resin, when plant nutrients such as nitrogen, phosphorus, potassium, etc. are put into the culture solution to be absorbed by the water-absorbent resin, the plant It was found that the cultivation solution was sucked up from the stem tube like a cut flower in water and did not root, and as a result, the plant did not root and did not last long, but it died. In other words, plants can absorb the nutrients by sucking the culture solution from the stem of the stem, so they do not make plant hormones that promote rooting and do not root. Based on the above findings, the present inventor has found that it is not preferable for the absorbent resin in the inner container to absorb a culture solution containing plant nutrients such as nitrogen, phosphorus and potassium.
The present invention has been completed based on the above findings.

(Object of the present invention)
Accordingly, an object of the present invention is to provide a plant cultivator comprising an inner container and an outer container that receives a culture solution to be passed through the inner container, so that a plant can be cultivated for a long period of time even if the cultivator has the same size. By doing so, it is possible to enjoy a long space in a limited space such as the room at home or on the office desk, and to reduce the number of irrigations.

  Another object of the present invention is to provide an ornamental plant and a method for cultivating the plant which can achieve the above-mentioned object.

  Another object of the present invention is to provide a plant cultivator in which the cultivation liquid in the outer container effectively acts on the growth of the plant.

Furthermore, another object of the present invention is to prevent the cultivation liquid from evaporating and to reduce the number of watering times.
Other objects of the present invention will become apparent from the following description.

Means taken by the present invention to achieve the above object are as follows.
In the first invention,

It is a plant cultivator which concerns on 1st or 2nd invention.

In the fourth invention,
A plurality of temperature-sensitive water-absorbing resins with different set temperatures for discharging the cultivation liquid are used,
It is a plant cultivator which concerns on 3rd invention.

In the fifth invention,
The plant is cultivated in the plant cultivator according to the first, second, third or fourth invention,
Ornamental plant.

In the sixth invention,
The roots of the plant are rooted in the inner container in which the water-absorbing resin that has absorbed the cultivation liquid is placed, and in the outer container in which the water-absorbing resin or / and the cultivation liquid that has absorbed the cultivation liquid is placed, It is characterized by growing roots of rooted plants,
It is a cultivation method of a plant.

  Examples of the material for the outer container and the inner container include plastics (synthetic resins), metals such as aluminum, wood, glass, and ceramics. Among these, a plastic one is preferable from the viewpoint of easy production of a light and transparent container and low cost.

  Examples of the shape of the outer container and the inner container include a circular, elliptical, square, or other polygonal or irregularly shaped cylindrical body or vessel-like shape in cross section, and other shapes. In order to prevent the cultivation liquid from evaporating, the outer container and the inner container are preferably provided with a lid, a plastic foam or the like instead of the lid.

  The outer container and the inner container may be transparent, translucent (having transparency), or opaque (colored). If it is transparent or translucent, the growth state of the roots of the plant can be observed from the outside. For example, when a water-absorbing resin that is colorfully colored like a fluorescent color is placed in a transparent or translucent container, the color is transparent from the outside, and the product has high design added value. In particular, the outer container may be excellent in design for ornamental purposes.

  The passage element provided in the inner container can include holes and meshes through which the roots can pass, and partially passes through a brittle material (such as paper) that allows the roots to pass through by their own force. Elements can also be configured. As used herein, “side wall or / and bottom wall” may include either the side wall or the bottom wall, or may include both the side wall and the bottom wall. In addition, the “root or / and the cultivation liquid” referred to in the present specification may include either the root or the cultivation liquid, or may include both the root and the cultivation liquid.

  It is preferable to include a plant active agent (plant hormone) in the culture solution for rooting the roots of the plant. Thereby, the root of a plant can be rooted forcibly or smoothly in a short period of time. As the plant active agent, auxin (indole acetic acid) which is a rooting promoter and cytokinin and kinetin which are cell division promoters are preferable.

  Between the inner container and the outer container, a water-absorbing resin or / and the cultivation liquid that has absorbed the cultivation liquid is placed. The “water-absorbing resin or / and the cultivation liquid that has absorbed the cultivation liquid” referred to in the present specification may include either the water-absorbing resin or the cultivation liquid that has absorbed the cultivation liquid, or may absorb the cultivation liquid. In some cases, the water-absorbent resin and the cultivation liquid are included.

  Examples of the shape of the water-absorbing resin put in the outer container and the inner container include powders, microbeads, fibers, and irregular shapes. Further, as described above, the water-absorbent resin may be colored in order to increase the added value in the design. Further, a fragrance may be added to the water absorbent resin so that a pleasant scent is emitted from the plant cultivator. In this case, it is preferable to add a colorant or a fragrance to the water-absorbing resin in the outer container, not in the inner container, so as not to affect the rooting of the plant as much as possible.

  Water-absorbing resins having different water-absorbing ability (water-absorbing speed) from the water-absorbing resin placed in the outer container can also be put in the inner container. For example, the cultivation liquid is smoothly passed from the outer container to the inner container by placing a water absorbent resin having higher water absorption (absorption capacity) than the outer container into the inner container. Thereby, even if it is a plant with the weak force which sucks up a cultivation liquid, the cultivation liquid in an outer container can be used effectively, and it grows up smoothly. In this case, the water absorption capacity (water absorption speed) may be changed by changing the type of water absorbent resin used, and the water absorption capacity (water absorption speed) may be changed by changing the size without changing the type of resin used. .

  In addition to the water-absorbent resin, zeolite, barley stone, and the like can be placed in the outer container and the inner container. Thereby, the rot of cultivation liquid can be prevented.

  All of the water-absorbing resin contained in the outer container may be a temperature-sensitive water-absorbing resin, or a part thereof may be a temperature-sensitive water-absorbing resin. All or part of the water absorbent resin contained in the inner container may be a temperature sensitive water absorbent resin. However, in order to effectively utilize the characteristics of the temperature-sensitive water-absorbent resin, it is preferable that all of the water-absorbent resin is a temperature-sensitive water-absorbent resin.

  The temperature-sensitive water-absorbing resin absorbs or discharges the cultivation liquid according to a change in temperature. Specifically, an N-alkyl-substituted acrylamide monomer such as N-isopropyl (meth) acrylamide, N, N-diethylacrylamide, Nn-propyl (meth) acrylamide, acryloylpyrrolidine, acryloylpiperidine and the like is used as a main component. Examples thereof include a polymer obtained by adding a crosslinkable polyfunctional monomer and polymerizing the monomer. In addition, other vinyl monomers can be copolymerized as necessary, such as control of the set temperature for absorbing or discharging the cultivation liquid, improvement in absorption capacity, etc. Examples include (meth) acrylamide, (meth) acrylic acid and salts thereof, butyl acrylamide, and diacetone acrylamide. As a commercial product, “Thermogel” (trade name, manufactured by Kojin Co., Ltd.) can be used.

  It is also possible to give the plant cultivator an aroma or / and deodorant effect. “Aroma or / and deodorant” may include either aroma or deodorant, or may include both aroma and deodorant. The fragrance action or / and the deodorant action can be imparted, for example, by putting the fragrance or / and the deodorant in a plant cultivator. It should be noted that the fragrance and / or deodorant is preferably provided separately so as not to be mixed with the cultivation liquid so as not to adversely affect the growth of the plant. The fragrance or / and deodorant may be impregnated in a water-absorbing resin, gel, or the like, regardless of properties such as liquid or solid.

(Work)
The present invention operates as follows.
Plant roots are rooted using the water-absorbent resin in the inner container as a medium. Since the cultivation liquid for rooting the root of the plant is absorbed in this water absorbent resin, the plant is rooted smoothly by the cultivation liquid. Roots rooted with a water-absorbent resin are roots suitable for a medium that does not include a gap through which air passes, such as water-absorbent resins and cultivation liquids (roots suitable for hydroponics). Therefore, the root rooted in the inner container grows steadily by extending to the water absorbent resin or / and the cultivation liquid that has absorbed the cultivation liquid in the outer container.

  Since the outer container can be received and attached, it is possible to employ a cultivation method in which only the inner container is used until the plant is rooted, and the inner container is combined with the outer container at the time of shipment.

  If the water-absorbing resin contained in the outer container contains a temperature-sensitive water-absorbing resin that absorbs or discharges the cultivation liquid depending on the temperature, for example, the temperature is high like in the daytime, and the transpiration of the plant is increased Sometimes, the temperature-sensitive water-absorbing resin can be used to drain the cultivation liquid, and the temperature-sensitive water-absorbing resin can absorb the cultivation liquid when the temperature is low and the transpiration of plants is reduced at night.

  What is used in combination with a plurality of temperature-sensitive water-absorbing resins with different set temperatures for discharging the cultivation liquid is, for example, those with different set temperatures such as 15 ° C., 20 ° C., 25 ° C., 30 ° C., and 35 ° C. In combination, the cultivation liquid is discharged step by step from the temperature-sensitive water-absorbent resin in response to the temperature rise in the environment where the plant cultivator is placed.

The present invention has the above-described configuration and has the following effects.
(A) According to the present invention, the root of the plant rooted in the inner container can be grown in the outer container in which the cultivation liquid or / and the water-absorbing resin that has absorbed the cultivation liquid are placed. Plants can be cultivated for a long period of time even with a cultivator of a size. Therefore, it can be enjoyed for a long time in a limited space such as the room at home or on the office desk.

(B) The root of the plant rooted in the inner container is not only a water-absorbent resin but also a root (water root) suitable for hydroponics. Therefore, even if the roots are immersed in the culture solution, the roots will not rot. Therefore, even if the outer container is filled with the cultivation liquid, there is no particular problem in plant growth. Thereby, the frequency | count of watering can be decreased.

(C) If the water-absorbing resin contained in the outer container contains a temperature-sensitive water-absorbing resin that absorbs or discharges the cultivation liquid depending on the temperature, for example, the temperature is high as in the daytime, and the transpiration of plants It can be used to drain the cultivation liquid from the temperature-sensitive water-absorbent resin when it becomes popular, and to absorb the cultivation liquid into the temperature-sensitive water-absorbent resin when the temperature is low and the transpiration of the plant is reduced, such as at night. Therefore, the cultivation liquid absorbed by the temperature-sensitive water-absorbent resin is sufficiently distributed to the plant and effectively acts on the growth of the plant.

(D) What is used in combination with a plurality of temperature-sensitive water-absorbing resins having different set temperatures for discharging the cultivation liquid has different set temperatures such as 15 ° C., 20 ° C., 25 ° C., 30 ° C., and 35 ° C. By combining a plurality of things, the cultivation liquid can be discharged step by step from the temperature-sensitive water-absorbent resin in response to the temperature rise in the environment where the plant cultivator is placed. Therefore, unlike the case where one kind of the same temperature-sensitive water-absorbent resin is used, it is possible to prevent a large amount of the cultivation liquid from being discharged from the temperature-sensitive water-absorbent resin at one time, thus preventing evaporation of the cultivation liquid. Can do.
Moreover, by preventing a large amount of the cultivation liquid from being discharged from the temperature-sensitive water-absorbing resin at once, it is possible to prevent the cultivation liquid from flowing out together with the water-absorbing resin even if the plant cultivator is accidentally defeated. .

  In addition, for example, when the cultivation container is filled with only the cultivation liquid and placed in the window where direct sunlight is inserted, the cultivation liquid is sucked infinitely from the roots due to intense transpiration of the plant, and the cultivation liquid is significantly reduced There is. Therefore, as in the present invention, if the cultivation liquid is discharged step by step by combining a plurality of temperature-sensitive water-absorbing resins having different set temperatures, the cultivation liquid can be prevented from being sucked infinitely from the roots. It can prevent the decrease of the cultivation liquid.

  EXAMPLES Hereinafter, although an Example demonstrates this invention, this invention is not limited to these.

  The invention will be explained in more detail on the basis of an embodiment shown in the drawing.

[Ornamental plants cultivated using plant cultivators]
FIG. 1: has shown the 1st Example of the plant cultivator which concerns on this invention, and is side view explanatory drawing which represented the internal structure by cross-sectioning the plant cultivator in the state which is growing the plant.

  The plant cultivator A <b> 1 includes an inner container 1 and an outer container 2 to which the inner container 1 can be attached and which receives a cultivation liquid that is passed through the inner container 1. The inner container 1 contains a water-absorbing resin 3 that has absorbed a cultivation liquid for rooting the roots 5 of the plant B. Between the inner container 1 and the outer container 2, a water-absorbing resin 4 that has absorbed the cultivation liquid is placed. The code | symbol B has shown the plant cultivated by plant cultivator A1, and an ornamental plant is comprised by the plant cultivator A1 and the plant B. FIG.

  Both the outer container 2 and the inner container 1 are made of transparent plastic, and the upper part is opened circularly. The magnitude | size of the outer container 2 and the inner container 1 is set suitably according to the kind of plant to grow. In this embodiment, the outer container 2 has an inner diameter of about 6 cm and a height of about 6 cm.

  The inner container 1 is inserted into the outer container 2 in which the water absorbent resin 4 is placed. The inner container 1 is held away from the bottom inner surface 21 of the outer container 2 by the water absorbent resin 4 in the outer container 2. The bottom of the inner container 1 may be in contact with the bottom inner surface 21 of the outer container 2.

  The inner container 1 is provided with a lid 11, and the plant B rooted with the water-absorbent resin 3 as a medium has a stem extended from a hole 111 formed in the center of the lid 11. The upper side of the inner container 1 slightly protrudes upward from the outer container 2. The outer container 2 is provided with a lid 22 having a hole 221 at the center so as to block the periphery of the inner container 1. The lids 11 and 22 placed on the inner container 1 and the outer container 2 prevent the cultivation liquid from evaporating from the water absorbent resins 3 and 4.

  In the lower part of the side wall of the inner container 1, a liquid passage hole 23 which is a hole through which the cultivation liquid can be passed from the outer container 2 is provided. The required number (two in this embodiment) of liquid passage holes 23 is provided in the inner container 1. The liquid passage hole 23 can also be provided on the bottom wall of the inner container 1. The liquid passage hole 23 has such a size that the root of the plant B rooted in the inner container 1 can pass to the outer container 2 and constitutes a passage element. In this embodiment, the hole diameter of the liquid passage hole 23 is about 3.5 mm.

  The water-absorbing resin 3 contained in the inner container 1 and the water-absorbing resin 4 placed between the inner container 1 and the outer container 2 are both temperature-sensitive water-absorbing resins. In some cases, the description is made with reference to the functional resins 3 and 4). The temperature-sensitive water-absorbing resins 3 and 4 absorb or discharge the cultivation liquid according to changes in temperature, absorb the cultivation liquid below a predetermined set temperature, and discharge the cultivation liquid when the predetermined set temperature is exceeded. To do. Each of the outer container 2 and the inner container 1 contains zeolite (not shown) together with the temperature-sensitive water-absorbing resins 3 and 4.

  The temperature-sensitive water-absorbing resin 3 placed in the inner container 1 is different from the temperature-sensitive water-absorbing resin 4 placed between the inner container 1 and the outer container 2.

  The temperature-sensitive water-absorbing resin 4 placed in the outer container 2 is a combination of a plurality of temperature-sensitive water-absorbing resins having different set temperatures for absorbing or discharging the cultivation liquid. Specifically, a plurality of (four types) of temperature-sensitive water-absorbing resins, which are set at different temperatures stepwise around 20 ° C, 25 ° C, 30 ° C and 35 ° C, are set for discharging the absorbed cultivation liquid. Something is used. That is, for example, when the set temperature is 20 ° C., the cultivation liquid is absorbed below 20 ° C., and when the temperature exceeds 20 ° C., the cultivation liquid is discharged. When the set temperature is 25 ° C., the cultivation liquid is absorbed at 25 ° C. or less, and when the temperature exceeds 25 ° C., the cultivation liquid is discharged.

  On the other hand, as the temperature-sensitive water-absorbing resin 3 placed in the inner container 1, one having a set temperature of 35 ° C. for absorbing or discharging the cultivation liquid is used. The temperature-sensitive water-absorbing resins 3 and 4 use the trade name “Thermogel” (manufactured by Kojin Co., Ltd.). The effect of this temperature-sensitive water-absorbing resin will be described later. Since the temperature-sensitive water-absorbing resin employs a known technique, a detailed description of the composition and the like is omitted.

  In addition, in FIG. 1, although the state which filled the water-absorbing resin which swollen the cultivation liquid into the outer container 2 was illustrated, the quantity of the water-absorbing resin to put is not specifically limited. For example, half of the swollen water-absorbing resin may be put and the upper half may be filled with the cultivation liquid.

[Plant cultivation method]
A plant cultivation method using the plant cultivator A1 will be described step by step. In addition, the cultivation method shown below shows one example, and it does not specifically limit to this method.

  First, the cultivation liquid put into the inner container 1 is adjusted. This cultivation liquid is for rooting the root 5 of the plant B, and does not contain plant nutrients such as nitrogen, phosphorus and potassium. First, a plant active agent (also referred to as a plant hormone) is diluted 1000 times with water (volume conversion) to obtain a culture solution. In this example, as a plant activator, a mixed solution of auxin as a rooting promoter and cytokinin as a cell mitogen (trade name “Biomajor M1”, manufactured by Major Green Laboratory) is used. Yes.

  Then, this cultivation liquid is added to the temperature-sensitive water-absorbing resin 3 and absorbed until saturated, and gelled. The temperature-sensitive water-absorbent resin 3 swells about 50 times in volume. Further, 10% by weight of zeolite as a soil conditioner is mixed with 100% by weight of the thermosensitive water-absorbing resin. The inner container 1 is filled with the temperature-sensitive water-absorbing resin 4 that has absorbed the cultivation liquid as described above as a culture medium, and the lid 11 is covered.

  The cut cuttings (buds) are sprouted from the holes 111 of the inner container 1 into the temperature-sensitive water-absorbent resin 3, rooted in a greenhouse, and nurtured. Thus, a plant is rooted in a short period of time by performing house cultivation using the cultivation liquid containing a plant activator. In addition, the root 5 is a root suitable for the water absorbent resin 3 placed in the inner container 1.

  Moreover, as mentioned above, the temperature-sensitive water-absorbing resin 3 in the inner container 1 uses a relatively high set temperature of 35 ° C. for discharging the absorbed cultivation liquid. This is higher than the temperature in the greenhouse. Therefore, even in a high-temperature environment in the greenhouse, the cultivation liquid is prevented from being excessively discharged, and evaporation of the cultivation liquid is prevented. In addition, even if temperature is 35 degrees C or less, since a root sucks up the cultivation liquid absorbed by the temperature sensitive water-absorbent resin 3, there is no problem in the growth of the plant B.

  On the other hand, after the temperature-sensitive water-absorbing resin 4 is put in the outer container 2 to absorb the liquid fertilizer as the cultivation liquid, the lid 22 is placed. And as shown in FIG. 1, the inner container 1 is inserted from the hole 221 of the outer container 2, and plant cultivator A1 is comprised.

  Since the inner container 1 can be detached from the outer container 2 in this way, only the inner container 1 is used until the plant B is rooted, and the inner container 1 is combined with the outer container 2 at the time of shipment. It is possible to adopt such a cultivation method. Therefore, when growing cuttings by house cultivation, a large amount of seedlings can be cultivated in a small space, so that productivity is high. Further, by combining the inner container 1 with the highly designable outer container 2 at the time of shipment, the plant cultivator A1 excellent for ornamental use can be obtained without soiling during cultivation.

  The cultivation liquid absorbed in the temperature-sensitive water-absorbing resin 4 in the outer container 2 passes through the liquid passage hole 23 provided in the inner container 1 and passes through the temperature-sensitive water-absorbing resin 3 to the inner container 1. As shown in FIG. 1, when a plant root grows, the root extends out of the inner container 1 through the liquid passage hole 23. Thus, since the root of the plant rooted in the inner container 1 can be grown in the outer container 2 in which the temperature-sensitive water-absorbing resin 4 that has absorbed the cultivation liquid is placed, the cultivation device of the same size Even so, plants can be cultivated for a long time. Therefore, it can be enjoyed for a long time in a limited space such as the room at home or on the office desk.

  Since both the inner container 1 and the outer container 2 contain temperature-sensitive water-absorbing resins 3 and 4 that absorb the cultivation liquid, the cultivation liquid does not spill even if it is slightly shaken or tilted. Therefore, when delivering from a producer to a retailer or the like, it is not necessary to pack so carefully and work efficiency is improved. Moreover, even if the plant cultivator A1 displayed on the desk or the like is accidentally knocked down, there is no inconvenience that the document gets wet. Furthermore, compared to those using soil, it is hygienic, with less germs and moss growing, and it does not smell like soil, so it can be easily placed on a table.

  Moreover, since the cultivation liquid is absorbed by the temperature-sensitive water-absorbing resins 3 and 4, evaporation of the cultivation liquid can be prevented as compared with the case where the cultivation liquid is simply put in the container. As a result, the number of irrigation can be reduced, so that the retailer does not have to do the irrigation. In addition, the effect of preventing the evaporation of the cultivation liquid is remarkable when the plant cultivator A1 is decorated after the purchase, especially at the window where direct sunlight is inserted.

  The temperature-sensitive water-absorbing resin 4 placed in the outer container 2 is mixed with a plurality of temperature-sensitive water-absorbing resins whose set temperatures for absorbing or discharging the cultivation liquid are stepwise different from 20 ° C., 25 ° C., 30 ° C., and 35 ° C. Use what you have. Therefore, the cultivation liquid can be discharged step by step from the temperature-sensitive water-absorbent resin 4 in correspondence with the temperature increase in the environment where the plant cultivator A1 is placed. Therefore, unlike the case where one kind of the same temperature-sensitive water-absorbent resin is used, it is possible to prevent a large amount of the cultivation liquid from being discharged from the temperature-sensitive water-absorbent resin 4 at one time, thus preventing evaporation of the cultivation liquid. be able to.

  In addition, by preventing a large amount of the cultivation liquid from being discharged from the temperature-sensitive water-absorbing resin 4 at once, the cultivation liquid flows out together with the temperature-sensitive water-absorbing resin 4 even if the plant cultivator A1 is mistakenly defeated. Can be prevented.

  Furthermore, unlike this example, for example, when the cultivation container is filled with only the cultivation liquid and placed in a window where direct sunlight is inserted, the cultivation liquid is sucked infinitely from the roots due to intense transpiration of the plant. , The cultivation liquid may be significantly reduced. Therefore, as in this embodiment, if the cultivation liquid is discharged step by step by combining a plurality of temperature-sensitive water-absorbing resins 4 having different set temperatures, the cultivation liquid can be sucked infinitely from the roots. It is possible to prevent the cultivation liquid from decreasing.

[Experimental Example 1]
Plants were cultivated using the plant cultivator A1 described above, and the growth state of plant roots was observed. The cultivated plant is peperomia. For the convenience of explanation, the same components as those described in the above-described plant cultivation method (see FIG. 1) are denoted by the same reference numerals.

  A cultivation liquid (plant activator “Biomajor M1” (trade name) diluted 1000 times (conversion)) was prepared by the same procedure as the cultivation method described above. This cultivation liquid was added to the water-absorbent resin 3 to absorb water until it was saturated, and gelled. Further, 10% by weight of zeolite as a soil conditioner was mixed with 100% by weight of the water-absorbent resin. The inner container 1 was filled with the temperature-sensitive water-absorbing resin 3 having absorbed the cultivation liquid as described above as a culture medium, and the lid 11 was covered.

  The peperomia cuttings cut to about 5 cm were sprouted into the water-absorbent resin 3 from the holes 111 of the inner container 1 and rooted in the greenhouse over about 3 weeks.

  On the other hand, the water absorbing resin 4 was put in the outer container 2 to absorb the liquid fertilizer as the cultivation liquid, and then the lid 22 was applied. Then, the inner container 1 rooted with peperomia as described above was inserted from the hole 221 of the outer container 2. On this day, the growth state of the roots of peperomia was observed.

  As a result, the roots of peperomia continued to grow steadily in the inner container 1 and began to extend to the outer container 2 through the liquid passage hole 23 of the inner container 1 in the second week. Even after one month, the peperomia roots continued to grow smoothly in the outer container 2, and the growth of the peperomia leaves was also good. Moreover, irrigation during this one month was unnecessary.

(Discussion)
As a result of Experimental Example 1, it is understood that those rooted in the inner container using the water-absorbing resin as a medium can extend the root to the water-absorbing resin in the outer container. That is, it can be seen that the roots of plants rooted with the water-absorbent resin as a medium are suitable roots for a medium that does not include a gap through which air passes like the water-absorbent resin that has absorbed the cultivation liquid.

[Comparative experiment example]
The peperomia rooted with the soil was replanted in the inner container, the plant was cultivated, and the growth state of the plant root was observed. The same inner container and outer container as the above-mentioned plant cultivator A1 were used. For convenience of explanation, the same portions as those in the first embodiment (see FIG. 1) are denoted by the same reference numerals.

  That is, soil was put into a seedling pot made of polyethylene, peperomia cuttings cut to about 5 cm were sprouted, and rooted in a greenhouse for about 4 weeks. The rooted peperomia was root-washed and replanted with the soil placed in the inner container 1.

  On the other hand, the water absorbing resin 4 was put in the outer container 2 to absorb the liquid fertilizer as the cultivation liquid, and then the lid 22 was applied. Then, the inner container 1 in which the peperomia was replanted as described above was inserted from the hole 221 of the outer container 2. On this day, the growth state of the roots of peperomia was observed.

  As a result, even after two weeks, the peperomia root continued to grow in the inner container 1 and did not extend to the outer container 2 through the liquid passage hole 23. The rooting state was not good, and some were clogged and withered. And even if one month passed, the roots did not extend to the outer container 2, and the roots were completely clogged in the inner container 1, and were dead due to lack of oxygen. Peperomia leaves also withered.

(Discussion)
As a result of the comparative experimental example, it is found that it is difficult to extend the root from the inner container 1 to the water absorbent resin 4 in the outer container 2 when the soil is rooted as a medium. In other words, the root of the plant rooted with the soil as a medium is a root suitable for a medium including a gap through which air passes, and does not include a gap through which air passes like a water-absorbent resin that has absorbed the cultivation liquid. It can be seen that the roots are not suitable for the medium.

FIG. 2: has shown the 2nd Example of the plant cultivator which concerns on this invention, and is side view explanatory drawing which represented the internal structure by cross-sectioning the plant cultivator in the state which grew the plant.
In addition, the same code | symbol is attached | subjected and shown to the same or equivalent location as Example 1. FIG. Moreover, about the location demonstrated in Example 1, description is abbreviate | omitted and difference is mainly demonstrated. The same applies to Example 3 described later.

  In the plant cultivator A2 according to the present embodiment, unlike the plant cultivator A1 according to the first embodiment, the outer container 2 is not filled with the water-absorbing resin, but the cultivation liquid 4a is placed therein. The evaporation of the cultivation liquid 4a is prevented by the lid 22 of the outer container 2.

  The cultivation method of the plant is almost the same as in Example 1, and the root 5 of the plant B rooted in the inner container 1 using the water-absorbent resin 3 as a medium is extended to the cultivation liquid 4a in the outer container 2. Yes. The root 5 rooted with the water-absorbent resin 3 not including a gap through which air passes is a root (water root) suitable for hydroponics. Therefore, the root 5 grows without root rot in the outer container 2.

  The water absorbent resin 3 in the inner container 1 is swollen by absorbing the cultivating solution until it becomes saturated. Then, when the root 5 of the plant B sucks up the cultivation liquid from the water absorbent resin 3, the cultivation liquid 4 a in the outer container 2 flows into the inner container 1 through the water absorbent resin 3. Therefore, the water absorbent resin 3 in the inner container 1 is always swollen to a saturated state.

  The liquid passage hole 23 is blocked by the swollen water absorbent resin 3. Therefore, unlike the case where the soil is put in the inner container 1, the cultivation liquid 4a does not flow into the inner container 1 and become full. Even if some air remains inside the liquid passage hole 23 and the cultivation liquid 4a enters the inner container 1, the roots rooted with the water absorbent resin 3 are roots suitable for hydroponics (water Root), the root rot does not occur in the inner container 1. Therefore, unlike the case where the soil is put in the inner container 1, the outer container 2 can be fully filled with the cultivation liquid 4a, so that the number of watering operations can be reduced.

  In addition, in FIG. 2, although the state which put only the cultivation liquid 4a in the outer container 2 is illustrated, you may put a required amount of water absorbing resin in the cultivation liquid 4a. In that case, for example, a required amount of a water-absorbing resin in which nutrients and colorants are absorbed can be added, and the nutrients and colorants can be eluted from the water-absorbing resin into the cultivation liquid. In addition, the water-absorbing resin that absorbs nutrients can be composed of a temperature-sensitive water-absorbing resin, and a large amount of nutrients can be eluted from the water-absorbing resin during the daytime when the temperature is high.

  Since other operations and effects are almost the same as those of the first embodiment, description thereof is omitted.

[Experiment 2]
Plants were cultivated using the above-mentioned plant cultivator A2, and the growth state of plant roots was observed. The cultivated plant is peperomia.

  The same procedure as in Experimental Example 1 was performed until the roots of peperomia were rooted in the water absorbent resin 3 of the inner container 1. On the other hand, the liquid fertilizer which is the cultivation liquid 4a was put in the outer container 2 and the lid 22 was covered. Then, the inner container 1 rooted with peperomia was inserted from the hole 121 of the outer container 2. On this day, the growth state of the roots of peperomia was observed.

  As a result, the roots of peperomia continued to grow steadily in the inner container 1 and began to extend to the outer container 2 through the liquid passage hole 23 of the inner container 1 in the second week. Even after one month, the peperomia roots continued to grow smoothly in the outer container 2, and the growth of the peperomia leaves was also good. Moreover, irrigation during this one month was unnecessary.

(Discussion)
As a result of Experimental Example 2, it can be seen that those rooted in the inner container 1 using the water-absorbent resin as a medium can extend the roots to the culture solution in the outer container. That is, it can be seen that the root of the plant rooted with the water-absorbent resin as a medium is a root (water root) suitable for hydroponics.

  FIG. 3: has shown the 3rd Example of the plant cultivator which concerns on this invention, and is side view explanatory drawing which represented the internal structure by cross-sectioning the plant cultivator in the state which grew the plant.

  In the plant cultivator A3 according to the present embodiment, a plastic foam 6 that is a water retaining material that absorbs the cultivation liquid is disposed above the water absorbent resin 4 in the outer container 2 (so as to surround the inner container 1). ing. The plastic foam 6 is composed of an open-cell sponge. Reference numeral 61 denotes a hole for inserting the inner container 1.

  The plastic foam 6 can prevent the cultivation liquid absorbed by the water-absorbent resin 4 from evaporating without providing a cover on the outer container 2. Moreover, when the water-absorbing resin 4 that has absorbed the cultivation liquid penetrates the plastic foam 6 to form a film, transpiration of the cultivation liquid is further suppressed. Furthermore, since there is no lid, there is no need to remove the lid during irrigation, which is convenient. Further, if the plastic foam 6 has flexibility or deformability, it is possible to insert even the inner container 1 having a slightly different diameter. Since other operations and effects are almost the same as those of the first embodiment, description thereof is omitted.

FIG. 4: has shown the 4th Example of the plant cultivator which concerns on this invention, and is side view explanatory drawing which represented the internal structure by cross-sectioning the plant cultivator in the state which grew the plant.
In addition, the same code | symbol is attached | subjected and shown in Example 2 and the same or equivalent location. Moreover, description is abbreviate | omitted about the location demonstrated in Example 2, and difference is mainly demonstrated.

  In the plant cultivator A4 according to the present embodiment, a container 7 that supports the outer container 2a is provided under the outer container 2a in which the cultivation liquid 4a is put. And in the container 7, the water absorbing resin 8 which absorbed the aromatic liquid and / or the deodorizing liquid is accommodated. The required position of the container 7 is provided with a required number of holes 71 for emitting a fragrance action and / or deodorizing action. Further, the container 7 is formed of a transparent or translucent synthetic resin, glass, or the like, and the water-absorbing resin 8 therein can be seen so that the replacement time can be known.

  Thus, it can use suitably also as a fragrance | flavor and a deodorizer in a toilet or a room by giving a plant cultivator A4 a fragrance action or / and a deodorant action.
