DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method and an apparatus for raising seedlings.

[0002]

2. Description of the Related Art Conventionally, as a method for growing seedlings (seedlings) such as fruit trees, flowers and trees for planting, an asexual propagation method generally called a cutting method has been widely used. In this method, a part of a plant such as a branch or a leaf is cut out, the cut side is exposed to soil, and an adventitious root is generated in the cut part to obtain a seedling.

[0003]

In the above-described cutting method, an adventitious root is generated from a cut end of a plant placed in the soil, and it takes a long time until the adsorbed root is implanted. There are many cases where implantation fails, such as when the plant body dies and does not occur, and there is a drawback that seedling productivity is poor.

[0004] It is an object of the present invention to provide a method and an apparatus for raising seedlings, which can surely grow plant seedlings in a short period of time and can improve the productivity of the seedlings.

[0005]

Means for Solving the Problems and Functions / Effects In order to solve the above-mentioned problems, the method for raising seedlings of the present invention is characterized by including the following steps. That is, microorganisms involved in the formation of humus
An active liquid obtained by flowing a liquid mainly composed of water through the microorganism holding body to be retained together with the microorganism, and by mixing the microorganisms in the microorganism holding body into the liquid in a living state together with humus ; Contact with the mother. By absorbing the active liquid into the mother, the mother is grown to obtain seedlings.

In the above method, a part of a plant can be cut and separated from a main body, and the separated plant part can be used as a parent of a seedling. Specifically, a branch or a leaf cut from a tree can be used. In this case, seedlings can be obtained by bringing the cut part of the plant part into contact with the active liquid and generating roots in the cut part. On the other hand, as a parent of a seedling, a plant seed or a seed potato can be used.

The present inventor has found that the following effects can be obtained by bringing the above-mentioned seedling matrix into contact with the above-mentioned active liquid and continuously absorbing the active liquid into the mother. I found it. That is, the mother of the seedling
In the case of a plant part cut and separated from the plant body, sufficient roots are surely generated in the cut part in a relatively short period of time, and subsequent growth to seedlings is faster than the conventional cutting method etc. Become. Also, when the parent of the seedling is a seed or a seed potato, the time until germination and the growth rate after germination increase.

Hereinafter, a method for producing the above-mentioned active liquid will be described in detail. First, the microorganism carrier can be constituted as one containing mainly humus.
In this case, microorganisms involved in the formation of humus (eg, fungi such as actinomycetes, faecal fungi, yeasts, etc., hereinafter referred to as humus-forming microorganisms) are retained as microorganisms retained by the carrier.
Is used, but other microorganisms may be added according to the purpose.

As the humus, those containing a weakly acidic low-molecular substance such as fulvic acid or humic acid or an iron complex thereof can be used, and those containing fulvic acid are particularly preferably used. Since these substances contained in the humus dissolve in the liquid and lower the pH, even if anaerobic microorganisms (for example, Escherichia coli and various pathogenic microorganisms) are mixed in the liquid, their proliferation is suppressed, and the humus-forming microorganisms are suppressed. It is possible to obtain a high quality active liquid containing only the active liquid. In particular, when these low molecular substances are in the form of iron complexes, as described in JP-A-6-39397, a reaction for generating active oxygen from a liquid is promoted. Reproduction can be suppressed more effectively. Here, the content of the weakly acidic low-molecular substance in the microorganism support is adjusted within a range where the above effect is not insufficient, and for example, 5% by weight or more is appropriate.

[0010] More specifically, the microorganism holding body may be obtained by molding the humus into a pellet together with a caking substance such as a clay mineral. As a result, the retention of the shape of the support in the liquid is enhanced, and the sustainability of release of microorganisms and humus is improved, so that the life of the support can be extended. As such a microorganism support, for example, humus pellets commercially available from Enzyme Co. under the trade name of EZ-901 can be used.

The microorganism holding body for holding microorganisms is composed of substances necessary for keeping the microorganisms alive, such as water and nutrients, and substances for maintaining the shape of the holding body itself. In a state where the microorganisms are not captured, they have a function of capturing and maintaining the microorganisms and releasing the captured microorganisms into the liquid by contact with the liquid. Here, the “living state” means that the water content in the holding body is kept low,
The term also includes a state in which a microorganism has temporarily stopped its life activity due to exposure to a low temperature. The microorganisms to be held in the holder may be contained in the material before the holder is formed, or may be penetrated into the holder after the formation.

On the other hand, as a liquid serving as a base of the active liquid, a liquid mainly composed of water and capable of surviving microorganisms is used. Here, a liquid in which various components are dissolved may be used as long as the survival state of the microorganisms is not extremely hindered. For example, components that are effective for maintaining and proliferating microorganisms can be dissolved. .

The above-mentioned holding body is integrated in a container or the like,
The liquid is circulated and circulated through an appropriate circulation passage, and the microorganisms in the holder are mixed into the liquid to generate an active liquid. At this time, the constituent material of the holder may flow out into the liquid together with the microorganism. Further, the microorganisms may grow in the holding body or in the circulating liquid while consuming the constituent substances of the holding body, substances dissolved in the liquid, and the like.

Next, when the parent of the seedling is a plant part cut and separated from the plant body, a method is possible in which the active liquid is brought into a fluid state and the cut part of the plant part is immersed in the flowing active liquid. It is. Thereby, the absorption efficiency of the active liquid to the plant can be further increased.

Further, the active liquid can be used in a state where at least a part thereof is absorbed and held in an absorbing medium. In this case, the cut part of the plant part is brought into contact with the active liquid absorbed and held therein by being held in the absorption medium. Such an absorption medium can be composed of, for example, ordinary soil or a compound thereof. In addition, porous granules such as pumice or fired porous ceramics (for example, trade name: clay ball), sand and gravel can also be used. In particular, when a porous ceramic fired body is used, the activity or growth of microorganisms in the active liquid may be sometimes promoted. Further, a fiber forming material mainly formed of glass fiber, synthetic fiber, wood pulp, or the like can be used, and such a fiber forming material can be used as a mixture with the above-mentioned porous granular material or gravel. it can.

Further, as the absorbing medium, a powder containing porous ceramic particles can be used. Thereby, the generation of roots from the plant parts and the subsequent growth of seedlings can be further activated.

As the powder as described above, various clay minerals containing hydrous aluminum silicate as a main component and purified products thereof (hereinafter, simply referred to as clay minerals) can be particularly preferably used in the present invention. Typical examples thereof include smectite, montmorillonite, bentonite, kaolinite, halloysite, pyrophyllite, sericite, chlorite, illite and the like, and purified products thereof. Further, plural kinds of various clay minerals can be used in combination. Further, synthetic inorganic substances having compositions or crystal structures similar to those of the above-mentioned various clay minerals can also be used. As such a synthetic inorganic substance, for example, synthetic smectite (for example, product name: Smecton, Kunimine Industries Co., Ltd.) can be suitably used. On the other hand, besides clay minerals, various inorganic substance powders such as activated clay, diatomaceous earth and activated alumina can be used. They can also be used as a mixture with clay minerals.

In the above method, the seedling obtained by the plant part generating roots in the absorption medium can be transplanted with the roots covered by the absorption medium. For example, when transplanting a seedling to a desired place and implanting it, there are many cases where compatibility of the root with the soil at the transplanting site poses a problem, but according to the above method, the root of the seedling does not adapt to the absorbing medium. The roots can be relatively smoothly blended with the soil to which the roots have been transplanted after transplantation. After removing the seedlings from the seedling raising equipment,
Even when transplanting is not performed immediately, the roots of the seedlings can be maintained in a normal growth state because the roots are covered with an absorbing medium containing microorganisms.

Next, the seedling raising apparatus of the present invention for carrying out the above-mentioned method for raising seedlings comprises a contact between the active liquid storage section containing the above-mentioned active liquid and the active liquid stored in the active liquid storage section. And a mother supporting portion for supporting the mother of the seedling in a state where the temperature is allowed. Here, when the parent of the seedling is a plant part cut and separated from the body of the plant, the mother supporting part contacts the plant with the cut part of the plant in contact with the active liquid. It shall be supported.
With this device, the above-described seedling raising method can be efficiently performed.

Next, the active liquid container can be formed as a container having an open upper surface. The aforementioned active liquid is to be contained inside. Here, the above-mentioned plant parts can be arranged at predetermined intervals in a state where a plurality of the plant parts stand up from the opening in the container body. In this case, the mother supporting portion is provided with a lateral support for supporting each of the plant parts at least from the side in the vicinity of the opening.
Thereby, while effectively utilizing the limited storage space of the container body, the plant parts can be arranged at a relatively high density, and the productivity of the seedlings can be increased.

Further, in order to carry out the method of bringing the parent of the seedling into contact with the active liquid in a flowing state, a circulating means for flowing and circulating the active liquid stored in the active liquid storing section can be provided.

In the above-mentioned apparatus, at least a part of the active liquid is accommodated in the active liquid accommodating portion while being absorbed and held by the absorbing medium, and the cut portion of the plant portion is held in the absorbing medium. Can be configured.

The liquid L can also be circulated while maintaining the temperature of the liquid L at an appropriate temperature by a heater or the like (not shown) provided in the holder housing 1 or the tank 3. Note that the liquid suction mechanism 12 may be omitted.

After the circulation for a predetermined time, when the liquid L becomes an active liquid containing a desired amount of microorganisms, the valve 11a is opened and the liquid L is recovered from the liquid discharge port 11. At this time, the liquid L may be collected while the pump 6 or the liquid suction mechanism 12 is operated, or the operation may be stopped and then collected. Further, the circulation may be performed while continuously supplying and discharging the liquid L from the liquid supply port 10 and the liquid discharge port 11. In addition, the liquid outlet 8 of the holder accommodating section 1 is provided with a liquid L having a particularly high content of microorganisms in the holder accommodating section 1.

Next, as for the method of using the seedling raising apparatus 101, as shown in FIG.
The plant portion 104 is cut out from the plant portion 05 and the plant portion 104 is inserted into the seedling raising device 101 from the mesh 103a so that the cut portion 104a side is downward as shown in FIG. As a result, the cut portions 104a of the plant parts 104 are immersed in the active liquid L, and absorb the active liquid L from the cut portions 104a. It should be noted that, due to evaporation and absorption by the plant part 104, the active liquid storage part 10
When the amount of the active liquid L in 2 decreases, FIG.
The active liquid L may be replenished as shown in FIG.

The plant part 104 absorbs the active liquid L,
As shown in FIG. 5A, a root 104b is formed near the cut portion 104a. When the roots 104b are fully grown, the plant portion 104 becomes a seedling (seedling).
It becomes a state usable as 106. The seedling 106 thus obtained can be transplanted into the soil 107 at a predetermined location, for example, as shown in FIG.

Next, in the example shown in FIG. 6A, two plates 110 are used in place of the net 103. A plurality of holes 110a penetrating in the plate thickness direction are formed in these plate-like members 110, respectively.
10a, the plant parts 104 are respectively inserted, and as shown in FIG. 3B, the holes 110a of the upper and lower plate-like bodies 110 are formed at positions shifted from each other, and the plant parts 104 are respectively inserted from different directions. I have come to support it. The arrangement interval of the holes 110a is adjusted according to the size of the plant part 104 to be inserted. Here, the plate-like body 110 is supported by the protruding support portion 102a, similarly to the above-described net 103.

On the other hand, in the example shown in FIG. 7A, the base support portion is formed by a plurality of rod-shaped members 111 which are stretched almost in parallel to the opening 102c of the active liquid storage portion 102. Two sets of the rows of the rods 111 are provided at different heights in the depth direction of the storage section 102. Both ends of each of the rods 111 are, as shown in FIG. Each of them is fixed by being fitted to a concave fitting portion 102b formed on the inner surface of 102. The plant parts 104 are adjacent rods 111
The rod-shaped body 1 is inserted between the upper and lower sets.
Numerals 11 are arranged so as to be shifted from each other in the arrangement direction, and as shown in FIG.
Are supported on the sides from different directions.

Further, as shown in FIGS. 14 (a) and 14 (b), the mother supporting portion is a plate-like member 118 fixed to the active liquid storage portion 102 so as to cover a part of the opening on the upper surface.
It can also be. The plate-shaped body 118 has a plurality of notches 120 that open in a trumpet shape on one edge side thereof, and a holding member 121 made of an elastic member such as rubber is provided on an inner edge of the notch bottom. It is fitted. Then, as shown in FIG. 3C, the plant portion 104 is sandwiched between the pressing members 121 on both sides by pressing the pressing member 121 toward the bottom of the notch 120 while elastically deforming the pressing member 121. It will be supported in the state where it was.

On the other hand, as shown in FIG. 14D, a support hole 122 may be formed in the plate 118 instead of the notch 120. This support hole 122 is
a and a tapered portion 122 b formed integrally therewith and decreasing in width toward the distal end.
By inserting the plant portion 104 into 2a and sliding it toward the tapered portion 122b, the plant portion 104 is fitted and supported by the tapered portion 122b. According to this configuration, even when the cross-sectional dimension of the plant portion 104 is not constant, the plant portion 104 is stably fitted to the tapered portion 122b at a position where the width of the tapered portion 122b corresponds to the cross-sectional size. There is an advantage that can be worn. In this case, the plate-shaped body 118 is provided at least in the peripheral portion of the tapered portion 122b so as to secure the pinching of the plant portion 104 and prevent the plant portion 104 from being damaged by excessive friction from the tapered portion 122b. Is preferably made of an elastically deformable material such as plastic.

(Embodiment 2) In the seedling raising apparatus 101 shown in FIG. 8, a pipe 125 having both ends communicating with the inside of the active liquid storage section 102 is provided. Is provided. When the pump 126 is operated, the storage unit 1
The active liquid L inside 02 enters the pipe 125 from one end thereof, passes through it and returns to the container 102 from the other end to circulate. Thereby, the active liquid L
Will always come into contact with the plant part 104 in the storage part 102 in a fluid state. In this case, the pipe 125 and the pump 126 constitute a circulation means. As shown in FIG. 9, a holder holding part 1 having the same configuration as that incorporated in the active liquid generating apparatus A of FIG. A configuration is also possible in which the active liquid L is brought into contact with the active liquid L and circulated.

Example 3 FIG. 10 shows an example of a seedling raising method in which an active liquid is brought into contact with a plant part while being absorbed and held in an absorbing medium. That is, FIG.
As shown in the figure, a predetermined amount of a porous ceramic powder as an absorbing medium, for example, a clay mineral powder 127 (for example, bentonite or the like) mainly containing hydrous aluminum silicate, and an active liquid L are kneaded and mixed to obtain a wet powder. An object 128 is formed. Then, as shown in FIG. 3B, the wet powder material 128 is laid with a predetermined thickness in the active liquid storage portion 102, and the cut portion side of the plant portion 104 is inserted and held therein. The plant portion 104 absorbs the active liquid L contained in the wet powder material 128, and establishes a root 104b in the wet powder material 128 as shown in FIG. In this case, it can be seen that the wet powder material 128 itself has a function as a base support portion.

Here, the viscosity of the wet powder 128 is
It is possible to maintain the state where the inserted plant part 104 stands up without falling down, and the roots 10 from the plant part 104 can be maintained.
It is desirable to adjust the mixing ratio between the clay mineral powder 127 and the active liquid L so that the growth of 4b is not hindered. Specifically, assuming that the compounding weight of the clay mineral powder 127 is 1, the weight of the active liquid L is approximately 0.1%.
It is adjusted in the range of 5-4. However, the seedling raising device 1
When the plant portion 104 can be prevented from falling down by providing a side support such as the net 103 on the 01, the mixing amount of the active liquid L can be made larger than that described above. In addition,
When the amount of the active liquid L in the wet powder material 128 decreases due to absorption or evaporation by the plant part 104, FIG.
As shown in FIG. 0 (b), the active liquid L
Sprinkle on the surface of this to make up for this.

Here, in order to maintain the normal growth of the plant part 104, the pH value is adjusted to be weakly acidic so that the activity of the microorganisms contained in the wet powder 128 is not hindered. It is preferable to adjust the pH value so that it is specifically in the range of 5 to 6.8, preferably 5.5 to 6.5. However, clay minerals often show weak basicity in many cases, and if the active liquid is kneaded as it is, the pH of the wet powder 128 may be biased toward basicity. In this case, a suitable acidic substance that does not adversely affect the activity of the microorganism can be added as a pH adjuster. As such an acidic substance, for example, various organic acids such as wood vinegar, acetic acid, and other fatty acids, minerals showing weak acidity, and charcoal can be suitably used.

In this way, if the plant portion 104 grows on the seedling 106 with roots in the wet powder material 128, as shown in FIG. 11A, the periphery of the root 104b becomes wet powder material. The cover 102 can be taken out of the storage section 102 while being covered with 128 (that is, an absorbing medium), and can be transplanted into another soil 107. If the seedling 106 is not to be transplanted immediately for shipment or sale, the root 1
In order to suppress the evaporation of moisture from the wet powder 128 covering the wet powder 128b, for example, as shown in FIG.
It is desirable to cover with 9.

As shown in FIG. 12 (a), the absorbing medium is replaced with a porous ceramic powder such as pumice or a fired porous ceramic body (for example, trade name: clay ball) as shown in FIG. Granular material 131 or sand and gravel can also be used. Further, as shown in FIG. 2B, a fiber forming material 132 mainly formed of glass fiber, synthetic fiber, wood pulp or the like can be used. Further, a mixture of the porous granular material 131 and the fiber forming material 132 can be used.

(Embodiment 4) FIG. 13 shows an example of a method and an apparatus for raising seedlings when the parent of the seedlings is a seed. That is, in the seedling raising device 151, the active liquid storage unit 102
Inside the fiber support 152 as a matrix support and an absorption medium
And the active liquid L is absorbed and held therein. Then, as shown in FIG. 13 (a), seeds 153 such as flowers and vegetables are sown on the surface or inside of the fiber-formed product 152, so that the seeds 153 become fibers as shown in FIG. 13 (b). The active liquid L retained in the formed matter 152 is absorbed to germinate and grow into a seedling 154. Here, the roots 154a protrude from the seeds 153 into the fibrous material 152 and support the grown seedlings 154.
Therefore, it is desirable that the fiber forming material 152 be made of a material that does not hinder the overhang of the root 154a, such as a fiber forming material having a relatively low filling density, for example, a fiber formed mainly of glass fiber or synthetic fiber.
