Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for cultivating cuttings. More specifically, the present invention relates to a method for cultivating cuttings which allows rooting and cultivation by a simple method without using a nursery bed containing soil.

[0002]

2. Description of the Related Art Cutting is one of the methods for propagating plants. Cutting is a method of cutting a part of a plant body (cutting) and inserting it into the soil to generate adventitious roots or adventitious shoots to obtain a new individual.

Usually, cuttings are rooted by directly inserting them into a polyethylene pot containing soil, a seedling raising tray for plug seedlings, a seedling raising box or the like. Then, the rooted cuttings are planted in soil and grown. Also, when cuttings are cut earlier than the time suitable for cutting, it is common practice to put multiple cuttings together in a plastic bag, seal them, and store them in the refrigerator. ing.

[0004]

However, the conventional methods for cultivating cuttings have the following problems. When the cuttings were stored in the refrigerator, the rooting portion was not protected and was stored in an exposed state in a plastic bag or the like, which could damage the cuttings during handling.

[0005] Since a polyethylene pot containing a soil or a nursery box is used as a nursery bed, the space occupied by the cuttings per individual is large and the weight is heavy. For this reason, the cost of transportation to remote areas was also high.

The roots of the cuttings that have grown in the soil are suitable for soil cultivation and cannot be used for cuttings for hydroponic cultivation. Specifically, when the cuttings rooted in the soil are hydroponically cultivated, all the roots are lost once again, and the roots suitable for hydroponics grow again. Thus, when the cuttings rooted in the soil were hydroponically cultivated, the roots that had turned into corners were wasted, which was inefficient.

There is also a problem that it is difficult to confirm the rooting state of cuttings from the outside in the conventional nursery beds because the roots are growing in the medium. Since the roots are rooted in the soil, the roots may be damaged when they are taken out from the nursery bed and planted in the soil, and as a result, the growth of cuttings may be delayed.

Furthermore, when the cuttings rooted in a polyethylene pot are planted, it is not possible to bury the cuttings in the soil together with the pot, so that the cuttings are removed one by one from the pot. You need to do some work. This work is very labor intensive for farmers who handle tens to hundreds of thousands, or even millions to tens of millions of cuttings. Also, the treatment of a large amount of polyethylene pots after use was a headache for farmers.

(Object of the Invention) Therefore, an object of the present invention is to provide a method for cultivating cuttings which can be rooted and cultivated by a simple method without using a nursery bed containing soil. That is. Another object of the present invention is to provide a method for cultivating cuttings that can be safely stored for a long period of time by a simple method and can be transported to a remote place at low cost. Another object of the present invention is to provide a method for cultivating cuttings which can be used as seedlings for soil cultivation or hydroponic cultivation. Another object of the present invention is to provide a method for cultivating cuttings, which is capable of easily confirming the rooting state and preventing the roots from being damaged during transplantation. Another object of the present invention is to reduce the labor required for re-planting rooted cuttings in soil or water, and unlike the conventional method, does not cause a problem of treating a large amount of polyethylene pots after use. It is to provide a method for cultivating cuttings. Other objects of the present invention will be clarified by the following description.

[0010]

[Means for Solving the Problems] The means of the present invention taken to achieve the above object are as follows. In the first invention, a biodegradable sheet member having water retention property and capable of passing roots is used to wrap at least a portion where roots of cuttings are rooted,
Next, a method of cultivating cuttings is characterized by performing rooting while the cuttings are wrapped with the sheet member, and then performing soil cultivation and / or hydroponic cultivation with the cuttings wrapped with the sheet member.

According to the second aspect of the present invention, a biodegradable sheet member having water retention property and capable of passing a root is used to wrap at least a portion where the cuttings are rooted and to preserve the cuttings. Is
Managing the cuttings wrapped with the sheet member under a temperature at which rooting does not occur, and in the case of rooting the cuttings, the sheet member wrapped with cuttings is made to contain water, and at a temperature at which rooting is possible. The method of cultivating the cuttings is characterized by performing soil cultivation and / or hydroponic cultivation while the cuttings are wrapped with the sheet member, when the cuttings are managed by the above method.

According to a third aspect of the invention, at least the rooted portion or rooted portion of the cuttings is wrapped or covered with charcoal. It is a method of cultivating cuttings according to the invention.

As plants used for cultivation of cuttings, all plants that can be cultivated by cutting correspond to this. Specifically, for example, herbaceous plants (including vegetables), flowering trees, fruit trees can be mentioned, and specifically, portulaca, cactus, chrysanthemum, carnation, peperomia, Saintpaulia, gloxinia, parsley and the like can be exemplified, but especially these It is not limited to. Further, among the above-mentioned plants, it is particularly suitable for cultivating succulent plants such as portulaca which is resistant to drought and cacti.

By wrapping at least the rooting portion of the cuttings with the sheet member, it is possible to prevent the cuttings from being damaged by a shock during storage or handling during long-distance transportation.

The sheet member is not particularly limited as long as it is water-retaining and biodegradable so that roots can pass through it. For example, either a non-woven fabric or a woven fabric can be used, or a composite thereof can also be used.
Examples of the material of the sheet member include natural materials, synthetic materials, and composites thereof. Specific examples thereof include pulp obtained from wood and other natural materials, and those obtained from biodegradable synthetic fibers and plastics, but are not particularly limited thereto.

Examples of biodegradable plastic materials include microbial systems such as biopolyesters (PHB / V, etc.), bacterial cellulose, microbial polysaccharides (bullan, curdlan, etc.), or fatty acid polyesters (polycaprolactone, polybutylene succinate, Polyethylene succinate, polyglycolic acid, polylactic acid, etc.), polyvinyl alcohol, polyamino acids (PMLG, etc.), other polyurethanes, chemically synthesized systems such as nylon oligomers, and further natural products such as chitosan, cellulose, starch, etc.
Alternatively, the above-mentioned blends and laminates may be mentioned, but the present invention is not limited to the above-mentioned ones.

The cuttings are stored at a temperature at which the cuttings do not root. Specifically, it is carried out at a temperature at which the plant does not root, and at a temperature at which the plant is frozen and the growth after storage is not hindered. It is also necessary to manage the cuttings in an environment where the cuttings are not too dry so that growth after storage is not hindered. A specific storage method is, for example, storage in a refrigerator kept at 3 to 8 ° C, but is not particularly limited thereto.
The storage temperature is not particularly limited because it depends on the type of plant. Further, when the cuttings are stored, it is desirable that the sheet member enclosing the cuttings does not contain water in order to suppress the metabolism of plants.

When rooting the cuttings, moisture is included in the wrapped sheet member at a temperature at which rooting is possible, and the cuttings are managed so as not to dry. The root grows through (penetrates) the sheet member. In addition, since the soil is not used, the roots thus grown are not roots suitable only for soil cultivation, and the cuttings are used as seedlings for soil cultivation or hydroponic cultivation. Can be used.

In the case of transporting cuttings to a remote place, when the cuttings are planted in soil or water and grown immediately even at the transportation destination, the cuttings are transported with the sheet member containing water in advance. It is desirable to do. On the contrary, when the cultivation is started at the transportation destination after a certain period of time, it is desirable to transport the cuttings with the sheet member containing no water. Furthermore, the rooted cuttings are planted in soil or water while being wrapped with a sheet member. Since the sheet member is biodegradable, it does not adversely affect the environment.

When the cuttings are wrapped or covered with charcoal, charcoal used is charcoal (bincho charcoal, paulownia charcoal, etc.), bamboo charcoal, coconut charcoal, or carbonized paper (newspaper, cardboard, etc.), or Examples thereof include various activated carbons that have been subjected to activation treatment, but are not particularly limited thereto. The charcoal used is preferably granular or / and powdery so that rooting of cuttings is not hindered. The roots can be made resistant to drought by wrapping the cuttings with charcoal or cultivating them. In addition, when the cuttings are cultivated by hydroponic culture, there is an advantage that the water is unlikely to rot due to the effect of charcoal.

[0021]

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited thereto.

[Embodiment 1] FIG. 1 is an explanatory view showing a work procedure until rooting of cuttings wrapped with a sheet member. In this example, Portulaca will be described as an example of the mother plant. This also applies to other embodiments described later.

As the sheet member 1 for wrapping the cuttings, a biodegradable dry non-woven fabric made of 100% natural wood pulp fiber (trade name "Kinocloth", manufactured by Oji Kinocloth Co., Ltd.)
Was used. The sheet member 1 is formed by dispersing pulp fibers in the air to form a mat, and has a lower web density than a wet non-woven fabric, and has excellent bulkiness and water retention. The same dry nonwoven fabric as in this example is used for the sheet member 1 used in other examples described later.

Cut a part of Portulaca and cut it 2
And In this embodiment, the size of the sheet member 1 is
The length is about 8 to 10 cm, the width is about 3 to 6 cm, and the thickness is about 0.5 to 1.0 mm, but it is not particularly limited thereto.

Several (or one) cuttings 2 are put together, and the sheet member 1 is wound around a portion (root side) where the cuttings 2 are rooted. The end of the sheet member 1 at the end of winding is fixed with a water-resistant adhesive 3. The amount of the adhesive 3 used is small, but a biodegradable adhesive is desirable so as not to adversely affect the environment especially when planted in soil. In addition, "koyori" made of biodegradable material such as paper without using adhesive 3
The cutting member 2 can be fixed by winding the sheet member 1 with such a material.

When the sheet member 1 is wound around the cuttings 2, care should be taken so that no gap is formed between the sheet member 1 and the cuttings 2. This is because if a gap is formed between the sheet member 1 and the cuttings 2, the rooting of the cuttings 2 may be hindered.

The cuttings 2 wound with the sheet member 1 are managed by standing in a seedling raising tray T for plug seedlings. Since the holes 10 are opened in the bottom of the seedling raising tray T, ventilation and water flow are well performed, and it is possible to prevent the root portion of the cuttings 2 from being corroded by moisture.

When the cuttings 2 are stored for a certain period of time, they are stored at a low temperature, for example, in a refrigerator kept at about 7 ° C. or lower. At this time, in order to suppress the metabolism of the plant and prevent rooting, the sheet member 1 enclosing the cuttings 2 is not allowed to contain water.

Next, when rooting the cuttings 2, the cuttings 2 (in the present embodiment, the seedling raising tray T) are taken out of the refrigerator, and water is put into the sheet member 1 using, for example, water contained in the container V. Make sure that the cuttings 2 are included and that the cuttings 2 are not dried. The roots 4 that have rooted by obtaining water pass (penetrate) through the sheet member 1 and grow.

When the cuttings 2 are transported with water contained in the sheet member 1, the container V containing water is not used, but the water is retained on a water-retaining sheet, newspaper or the like. Place the seedling raising tray T on which the cuttings 2 are arranged. In this way, there is no fear of water spilling during transportation, and convenience is high.

FIG. 2 is an explanatory view showing a state in which rooted cuttings are being grown, of which FIG. 2 (a) shows soil cultivation and FIG. 2 (b) shows hydroponic cultivation. 2 (b)

In this embodiment, the cup-shaped container C is inserted and fixed in the hole 51 of the support plate 5 provided in the vase F, and a predetermined amount of charcoal 6 is filled therein. Then, in the charcoal 6, put the cuttings 2 wrapped with the sheet member 1 and rooted,
Cover at least the rooted part of cutting 2 with charcoal 6.

Portulaca roots 4 extended through charcoal 6
Has a characteristic that it is whiter and more fibrous (like downy hairs) and more resistant to dryness than roots that are rooted with the conventional soil.

The portulaca cultivated in this way is attractive as an ornamental flower, because the flowers and leaves with bright colors such as red and green contrast with the delicate white roots. Are better. Also, because the roots 4 are resistant to drought, even if you forget to give water or there is a period when you can not give water for a long trip etc., by giving water again, it will return to the original state and the plant will I can't wither.

The cuttings 2 which have not yet been rooted
May be planted in a container C containing charcoal 6. Further, the cultivation method shown in the present embodiment can be applied to soil cultivation. In this case, it is desirable to form the container C containing the charcoal 6 from a biodegradable material.
