DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swelling compressive planting material comprising moss suitable for cultivation of western orchids.

[0002]

2. Description of the Related Art Water moss is used as the most common compost indispensable for cultivation of Western orchids. As an advantage,
Good drainage and moisturizing, and good absorption of fertilizer. On the other hand, compared with other planting materials, there are disadvantages such as perishability, difficulty in planting until getting used to it, and difficulty in grasping watering, but these disadvantages can be overcome through repeated cultivation history and skill. In the long run,
No planting material is said to be superior to water moss. However, most of the moss currently on the market is imported and dried, so it cannot be used as it is, and when used for replanting, it contains enough moisture,
It is difficult to handle, such as putting a necessary amount of water moss in a large plastic bag, spraying it with fog, sealing it, putting it on the sun, leaving it for about half a day, and using it after it contains sufficient moisture. Also, as shown in Fig. 9, it is necessary to replant several times as it grows, but the old moss is removed so that the roots are not broken, and the new moss is spread evenly between the roots. It is necessary to put in, and skill is required. Moreover, it is necessary to adjust the management mode such as watering depending on the amount of water moss used. However, since the water moss is replaced by hand by hand, the orchid cultivation is difficult. In addition, although moss relies on imports from China or New Zealand, it is bulky and expensive to transport, and difficult to handle, even when transported dry.

[0003]

Therefore, while the present invention reduces the cost of transporting moss and is easy to handle,
An object of the present invention is to provide a planting material that can appropriately perform cultivation of Western orchids without requiring skill. By the way, a planting material obtained by pressing the pulp portion of a coconut tree in a direction substantially perpendicular to the direction of the fiber bundle and then cutting the plant as a plant planting material has been proposed (Japanese Patent Publication No. 63-52).
No. 848), although water moss is not pressed into a desired compressed planting material even when pressed in a water-retaining state, once compressed in a certain dry state, it is compression-molded into a plate shape,
It has been found that there is a property of naturally expanding and returning to the original state by water absorption.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been completed based on the above-mentioned findings, and relates to an expandable implantable material obtained by compression-molding dried water moss in the shape of a hollow truncated cone or a disk.

[0005] As dried moss subjected to compression molding, dried moss after being imported into Japan has too low a water content to have poor moldability even when compressed, whereas when dried from China or New Zealand, When it is dry, it can be fully compressed and formed into a plate shape, and it has excellent water absorption even in the compression molded state, and expands 5 to 20 times by water injection or water immersion to give a prescribed planting It can be a material.

Since water moss has a pH of about 4.5 when absorbing water, it is preferable to contain powdered coal or activated carbon in order to set the pH at around 5.5, which is suitable for Western orchid cultivation, and to improve root growth. The filling amount is suitably 10 to 15% by volume of the dried moss.

[0007] Further, as shown in FIG. 1, when this compression molded shape is formed into a simple disk 1 by compression molding,
As shown in FIG. 2, it is preferable that the cut 2 is formed from the center of the disk 11 toward the circumferential end so that the intermediate portion 33 between the leaf 31 and the root 32 of the seedling 3 can be inserted. FIG.
As shown in FIG. 7, a plurality of cuts 21 may be formed radially from the center of the disk 12 slightly outside and the roots 32 may be distributed. Therefore, as shown in FIG. 4, the implantable material of the present invention has a compression-molded water moss plate 11 having a cut 21 formed from a center portion toward a circumferential end as an upper portion, and a compression-molded water moss having no cut at a lower portion thereof. The boards 1 may be overlapped to form an implantable material set,
As shown in FIG. 5, a notch 2 is formed from the center to the circumferential end.
3 may be interposed between the compression-molded moss 11 formed with No. 1 and the compression-molded moss disc 1 having no cut at the lower portion thereof.

On the other hand, as shown in FIG.
00, as shown in FIG.
It is preferable to form a slit groove 102 in the vertical direction 1 so that the diameter of the truncated cone can be adjusted according to the division interval. Normally, Western orchids are repotted into shipping pots via a 2 to 3 inch pot and a 3 to 4 inch pot, but at the time of repotting, as shown in FIG. The hollow frustoconical plate 100 is wound around the water moss 31 of the seedling 3 obtained, or is inserted together with the seedling into a repot having the hollow frustoconical water moss 100 inserted thereinto so as to contain water. Replanting is completed.

[0009]

The compressed dry water moss according to the present invention is formed in a thin hollow truncated conical shape or a disk shape and is not bulky and is suitable for transportation and storage. It expands 20 times. Therefore,
By absorbing water in the pot, it becomes an implant material having a predetermined water retention. If activated charcoal is filled in the water moss disc, a pH suitable for a cultivation environment is set in a water retaining state. Also, as shown in FIG. 4, the moss laver 11 with the cut 2 and the moss laver 1 without the cut are superimposed on each other, and the cut 2 is provided between the leaf portion 31 and the root portion 32 as shown in FIG. When the root 33 of this combination is placed on the upper surface of the moss laver 1 and water is absorbed in the pot, the upper moss laver 11 pushes the root 32 downward, and the lower moss laver 1 Since it will push the root part 32 upward,
In the meantime, the root portion 32 is sandwiched and expanded. Further, as shown in FIG.
As shown in (2), the horizontal extension of the root portion 32 is slightly suppressed, and the lower end of the root portion 32 is pressed horizontally and spreads while the root portion 32 extends in the vertical direction. Alternatively, the water moss is wound around the seedlings appropriately by flooding. As shown in Fig. 12, the hollow frustoconical shape is wound around the seedlings in a repot, and expanded by injecting water so as to uniformly press inward, and water moss is easily spread around the seedlings. Can be wound (see FIG. 6B).

【Example】

(Production Example 1) Dried moss was dried from New Zealand moss by a conventional method, and 7 g of the moss was pressed into a 75 mm diameter press die, 3.5 g was pressed into a 55 mm diameter press die, and 3 g was pressed into a 45 mm diameter press die. The mold is filled and compression-molded at a compression pressure of 6 t / cm to form a compression molding board 1 having a thickness of 3 to 5 mm. It was confirmed that when the 7 g of the compression molding machine 1 was immersed in water, water-retained water moss having a maximum height of 50 mm and a volume of about 250 cm ³ was expanded. It was also confirmed that the water moss expanded about 10 times by immersion in water with respect to the other compression molding machines 1. Next, in order to form a cut 2 extending from the center to the circumferential end of the mossy board, a cut forming core corresponding to the cut 2 is placed in a mold and compression-molded in the same manner as described above. 11 was formed. When immersed in water,
It was confirmed that water-retained water moss having a maximum height of 50 mm and a volume of about 250 cm ³ was swollen, and the above-mentioned cuts almost disappeared when the hand was lightly pressed.

(Production Example 2) When forming the above-mentioned moss laver 1 or 11, activated carbon equivalent to 10 to 15% of the compressed capacity of the dried moss is placed in a mold at the same time as or with the dried moss. After the filling, post-filling was performed from the upper portion, and an activated carbon-filled moss laver 1 or 11 was formed in the same manner as in Production Example 1. Although this moss laver has a smaller coefficient of expansion due to water absorption than that produced in Production Example 1, the internal pH is about 5.5, and
It was confirmed that the water retention pH of the water moss was higher than that in the case of the above, and an ideal Western orchid cultivation environment was obtained.

(Production Example 3) Water moss was dried from New Zealand moss by a conventional method, and 10 g of the moss was wrapped around the outer periphery 15 c
m, 9cm in inner circumference, 5cm in width, 5mm in thickness, pre-compression molding, then set to be bonded to the inner periphery of a frusto-conical press die, insert the same wedge-shaped mold and compression-mold And outer circumference 15cm, inner circumference 9cm, height 5cm,
A dried water moss disc 100 having a thickness of about 3 mm and having a truncated hollow cone shape is formed. The compression pressure is suitably about 6 t / cm, as in the above-mentioned Production Example 1. When the rice paddy is replanted from a 2 inch pot to a 3 inch pot, it is wrapped around the outer circumference of the 2 inch pot seedling, inserted into the 3 inch pot as it is, and injected with water. A state in which the inside of the three-dimensional bowl is continuously filled with swelling water moss.

(Production Example 4) In forming the moss laver 100, activated carbon equivalent to 10 to 15% of the compressed capacity of the dried moss is filled in a mold simultaneously with or after filling with the dried moss. Bottom filling was performed from the upper part, and an activated carbon-filled moss laver 100 was formed in the same manner as in Production Example 3. This moss laver is manufactured in the above Production Example 3
Although the coefficient of expansion due to water absorption is lower than in the case of the production in the above, the internal pH is about 5.5, the water retention pH of the moss is higher than in the case of Production Example 3, and an ideal orchid cultivation environment is obtained. I confirmed that it would be.

[0014]

As is clear from the above description, according to the present invention, since usually dry bulky moss is compression-molded into a hollow truncated cone or a disk, it is convenient for transportation and storage. It can be easily returned to the original water retention moss by flooding. In addition, it becomes possible to automatically wrap around the root part by absorbing water expansion by using a water-moisture disc of a hollow frustoconical shape around the seedling, or using a different form of water-moisture disc in the case of a disc, Moreover, since quantification is possible, it is easy to replant Western orchids, and it is easy to optimize cultivation management.
