DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating a plant and an apparatus for carrying out the method, and more particularly to a method for cultivating a first stage using waste of a beverage container commonly called a PET bottle. The present invention also relates to a plant cultivation method and apparatus for performing second-stage cultivation using a hydroponic cultivation apparatus.

[0002]

2. Description of the Related Art When cultivating plants in flower pots, it often happens that plants are withered due to forgetting to water them. For this reason, recently, a reservoir for a water reservoir is continuously provided below the flowerpot, and a nonwoven fabric or the like is interposed between the container and the flowerpot, so that water is applied to the pot soil by utilizing the capillary phenomenon of the nonwoven fabric or the like. What is provided so that replenishment can be performed is provided.

[0003]

As described above, even in a flowerpot provided with a reservoir for water, a relatively large amount of water is required especially in a growing season or when water evaporation is severe in summer. Moisture disappears in a short time, and although it is not as high as a pot without a water reservoir, the plant may also die. In addition, even if the water does not die, if the water runs out, it takes a long time to recover the water, and the growth of the plant is greatly delayed. That is, in cultivation using a flower pot, in addition to the factor of root clogging, there is a limit to plant growth due to such unstable water supply.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above problems, and has a first stage in which cultivation of a plant is performed in a cultivation container having a water reservoir, and an automatic supply of water periodically. This is a method for effectively growing plants by performing the second stage of cultivation using a hydroponic cultivation apparatus. In particular, the first stage of cultivation uses a cultivation container using a PET bottle and the second stage of cultivation. A cultivation method of a plant and a cultivation instrument used for the cultivation method, characterized in that the cultivation container using the plastic bottle can be used as it is in the cultivation at the stage.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first stage of cultivation, a PET bottle having a capacity of about 1 to 2 liters filled with drinking water, juice and the like is divided into two upper and lower parts, one of which is a plant cultivation unit. By using the other as a water storage unit, for example, cultivation of a plant from seeding to a certain size is performed.

Next, if the plant has grown to a predetermined size, the hydroponic cultivation apparatus previously proposed by the inventor (vertical hydroponic cultivation apparatus / Japanese Patent No. 1863713, Japanese Patent Application No. 5-116).
No. 570, Japanese Utility Model Application No. 8-287281, etc.) or this plant is transplanted together with the plant portion into a more simplified hydroponic cultivation device. In this hydroponic cultivation apparatus, a plurality of implantation members are provided for a vertical support cylinder forming the apparatus main body, and the plant cultivation section of the cultivation container made of the plastic bottle is inserted into the planting section of the implantation member. Deploy.

[0007] Since the nutrient solution is supplied to the planted plant at a preset time interval, the nutrient solution cultivation device basically does not wither with water. Continue to grow with supply.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 and 2 show a method for constructing a cultivation container used for the first stage plant cultivation of the present invention. First of all, Fig. 1 shows the capacity after using contents such as juice and soft drink.
It is a 5 liter plastic bottle. This plastic bottle 1
Is cut first along the line L1 into upper and lower parts, and then the cut lower part of the PET bottle is adjusted to the line L2 to adjust its height.
Cut along.

[0009] Of the two divided PET bottles 1, the upper part of the bottle is used with the opening 2a serving as a spout located at the lower part. Hereinafter, the upper part of the bottle is referred to as a pot part 2. A net 3 is arranged in the pot 2 so as to cover the opening 2 a of the pot 2, and one end of the water supply cloth 4 is placed through the net 3 so as to be located in the pot 2. Since the water supply cloth 4 is for supplying water into the pot by capillary action, any material that causes capillary action may be used as a woven cloth or a non-woven cloth. In this state, the pot 2 is filled with the soil 7. The size of the mesh of the net 3 is the filled soil 7
Is desirably set to a large value within a range in which the roots of the cultivating device do not fall so that the root of the plant passes through the opening 2a during the second stage of cultivation described below. It can be extended inward and is even more effective.

On the other hand, the lower part of the plastic bottle 1 is formed as a water container part 5 and is filled with water or a nutrient solution (hereinafter referred to as "nutrient solution") 6 in which a fertilizer is added to water.
The pot portion 2 is arranged with respect to the water container portion 5 such that the tapered portion 2b in which the opening 2a is located at the center is located in the water container portion 5, and the pot portion 2 and the water container portion 5 are arranged. Are integrated. Thus, the nutrient solution 6 in the water container portion 5 is gradually supplied to the soil 7 of the pot portion 2 by capillary action of the water supply cloth 4, and the seeds sown on the soil 7 germinate and grow as plants P.

In the cultivation container using the above-mentioned plastic bottle, the plant P grows by the water appropriately supplied through the water supply cloth 4. However, as time passes, it becomes necessary to add a nutrient solution to the water container 5, and if this water supply is forgotten, the plant P will be greatly adversely affected, including withering. In addition, a light beam enters the water container part 5 and the nutrient solution 6
Since the water stays in the water container section 5, algae are generated in the nutrient solution 6 with the elapse of time, and water quality is deteriorated due to decay of the algae. For these reasons, the plant P sown in this state grows relatively slowly in a short time.

When the cultivation by the PET bottle reaches a certain limit, the cultivation of the second stage using the vertical hydroponic cultivation apparatus is started. Prior to describing the second stage cultivation, the configuration of the vertical hydroponic cultivation apparatus used for this cultivation will be described.

FIG. 3 shows the overall configuration of the vertical hydroponic cultivation apparatus, and the arrow 11 indicates an implanting member forming a part of the vertical hydroponic cultivation apparatus. As shown in FIG. 4, the implanting member 11 includes a nutrient solution receiving unit 12 and a planting unit 13.
Numeral 3 is integrally formed with the nutrient solution receiving portion 12 so that its central axis is substantially orthogonal to the nutrient solution receiving portion 12.

The nutrient solution receiving part 12 is formed in a substantially cylindrical shape as a whole, and a weir plate 12 is provided at an end opposite to the planting part 13.
An opening 12b is formed at the lower end of a (see FIG. 5). As shown in FIGS. 4 and 5, a plurality of slits 1 are formed on the upper wall surface of the nutrient solution receiving portion 12 along the circumferential direction of the wall surface.
2c is formed. On the other hand, the upper end of the planting part 13 orthogonal to the nutrient solution receiving part 12 is opened as a planting opening 13a.

Next, FIG. 3 mainly shows the configuration of the entire hydroponic cultivation apparatus. Reference numeral 14 denotes a nutrient solution tank, and reference numeral 15 denotes a support cylinder provided upright with respect to the nutrient solution tank 14. A plurality of openings 15a are formed in the peripheral wall of the support cylinder 15,
The nutrient solution receiving portion 12 of the implanting member 11 is inserted into these openings 15a, and the implanting member 11 is
It is supported by.

Numeral 16 designates a hose forming a part of the nutrient solution supply means, which is located by sewing each nutrient solution receiving portion 12 which protrudes into the support cylinder 15, and one end of which is an upper end of the support cylinder 15. Is connected to the nozzle 17 formed at the bottom. The other end of the hose 16 is connected to a submersible pump 18 which is a water pump disposed in the nutrient solution tank 14. In the illustrated configuration, a timer 19 is connected to the power supply side of the submersible pump 18,
Automatic water supply is configured.

FIG. 5 shows a state in which the plant P which has been cultivated in the first stage shown in FIG. The illustrated method shows a case where the pot portion 2 of the plastic bottle is directly placed in the planting portion 13 of the planting member 11. That is, the pot portion 2 in FIG. 2 is detached from the water container portion 5, and the pot portion 2 is arranged in the planting portion 13 as it is. Incidentally, since the inside diameter of the planting part 13 is substantially equal to the inside diameter of a plastic bottle having a circular cross section of 1.5 liters,
Is simply placed in the planting section 13 as it is, and the installation on the vertical hydroponic cultivation apparatus is immediately completed as shown in FIG. In this case, the water supply cloth 4 is connected to the nutrient solution receiving portion 12
Are arranged so as to extend in the axial direction. Note that, depending on the length of the water supply cloth 4, the end portion may hang down through the opening 12b.

FIG. 6 shows the structure of a supporting member used when the pot portion 2 is small. The support member 20 includes a ring portion 20a having a diameter smaller than the inner diameter of the planting portion 13, and a plurality (three in the illustrated case) of locking portions 20b fixed in the diameter direction of the ring portion 20a. Of these, 20b ₁ is engaged with the outer peripheral wall of the planting portion 13 to support the entire support member 20, and 20b ₂ is located in the planting portion 13 and supports the small-diameter pot portion 2. FIG. 3 shows a state in which a small-diameter pot portion (indicated by reference numeral 2A) is arranged in the lower implanting member 11 of FIG.

In the above configuration, when the time set in advance by the timer 19 is reached, the submersible pump 18 is operated and the nutrient solution W in the nutrient solution tank 14 (may be the same as the nutrient solution 6 used in the cultivation tool of FIG. 2). And water is supplied dropwise from the nozzle 17. Since the nutrient solution receiving portion 12 of each implanting member 11 is located at the dropping position of the nutrient solution W, the dropped nutrient solution W enters the nutrient solution receiving portion 12 through the slit 12c, and the plant P
Of the nutrient solution W directly or indirectly through the water supply cloth 4
And the unnecessary nutrient solution W flows out of the opening 12b.

In the above-mentioned vertical nutrient solution cultivation apparatus, since the nutrient solution W is supplied periodically with an interval, the root rot is less likely to occur than in the configuration shown in FIG. 2 in which the roots are constantly immersed in the nutrient solution. And root elongation is very good. Also, since the inside of the nutrient solution tank 14 is shielded from light, there is no generation of algae,
Therefore, the nutrient solution does not rot. As a result, even if the plant has slowed growth in the cultivation device shown in FIG. 2, when it is transplanted to the cultivation apparatus, the growth speed increases and the plant grows smoothly.

FIG. 7 shows a second embodiment. In the case of this embodiment, the plant P is taken out from the pot portion 2 and planted. That is, the plant P is extracted from the pot portion 2 of the cultivation tool together with the soil 7. In this case, since a large number of roots are circulated in the soil 7 by cultivating the soil in the pot portion 2 for a certain period of time,
Hardly collapses. The net 3 and the water supply cloth 4 are also left as they are, and the soil 7 is planted in the planting section 13 of the planting member 11. Further, the water supply cloth 4 is arranged so as to extend into the nutrient solution receiving portion 12 as in the case of the above embodiment. This example is particularly effective for plants with good rooting because the roots are more free to elongate. By the way, in the case of a plant having good rooting, many roots are rotating even in the pot portion 2, so that even if the plant is removed from the pot, the soil 7 hardly falls.
