【Example】

Hereinafter, embodiments will be described in detail with reference to the drawings. First, FIGS. 1 and 2 show the usage state of the artificial culture medium material 13 for plant cultivation of the present invention. The artificial medium material 13 for plant cultivation has a flat mat-like shape and is cut to a size that fits exactly in the frame 14.
As shown in Fig. 1, frame 1 was planted as shown in Fig. 2 when sowing seeds or planting seedlings in 3 and growing to a state suitable for ornamentation as shown in Fig. 1.
It is attached to No. 4 so that it can be hung on the wall.

Next, the manufacturing process of the artificial medium material 13 for plant cultivation will be described with reference to FIG. First, a thermoplastic synthetic resin is melted and the molten resin is spun out from a downward nozzle 1 provided in a die of an extruder to form a filament 2, and the filament 2 is naturally lowered. The diameter of each nozzle 1 is set so that the filament 2 is thin on the outside and is thick on the inside. The molten resin is preferably colored with a light-shielding color in consideration of the growth of plant roots. In addition, the powdery granular soil 4 is dropped from the pipes 3 arranged at required positions between the nozzles 1 at the same time when the cotton strip 2 is naturally lowered. This soil 4 is vermiculite,
It is composed of a porous inorganic substance such as pearlite or Kanuma soil mixed with a water-retaining agent of highly water-absorbent resin particles and a resin-coated fertilizer. The soil 4 is adjusted so that one having a large particle size falls from the pipe 3 located outside and one having a small particle size falls from the pipe 3 located inside. Further, from the air injection nozzle 5 disposed at a required position between each nozzle 1 and each pipe 3, the filament 2 which is still in the unsolidified state and is in the descending process while maintaining flexibility, and the soil which is also in the falling process. 4, the required amount of air 6 given the required temperature and the required ejection speed is continuously or intermittently jetted to disperse and mix the soil 4 between the filaments 2 while bending the filaments 2. Then, the contacts are crossed with each other, and the adhesiveness is used to bond the contacts to each other. The air injection nozzle 5 is mounted so as to be rotatable and reciprocally movable in the horizontal direction.
Each of the filaments 2 has a large degree of fold of an outer one having a small diameter and a small degree of fold of an inner one having a large diameter, that is, the outer filament density is high and the inner filament is The amount of the air 6, the temperature, the injection speed, the rotation speed of the air injection nozzle 5, the reciprocating speed, and the like are appropriately set so that the density becomes low. Further, the intermittent or continuous operating state of the air jet nozzle 5 is also adjusted appropriately. As a result, the soil with a small grain size 4 is mixed in the inner portion with a low filament density, but the soil with a large grain diameter 4 is filled in the outer portion with a high grain density. It becomes extremely difficult to remove the soil 4 from the space. Next, the filaments 2 continue to descend while the outer edges of the filaments 2 are aligned by the curtain of the water stream 8 falling along the guide plate 7 arranged on the outer peripheral portion, and the air blowing pipe 9 for pre-cooling is interposed therebetween. The first take-up roll 10 and the second take-up roll 1 whose rotational speeds can be adjusted respectively.
Taken by 1. The take-up speed of the second take-up roll 11 is usually set to be slower than that of the first take-up roll 10. Therefore, the filaments 2 which have already been folded to some extent are refolded by the air jetting suzzle 5 and the final density is adjusted. That is, if the difference between the take-up speeds of the first take-up roll 10 and the second take-up roll 11 is increased, the degree of fold is increased and the density is increased. When each filament 2 passes through the second take-up roll 11, it is completely cooled and solidified, and the three-dimensional reticulate body 12 in which the internal voids are filled and held with the soil 4, that is, the artificial culture medium material 13 for plant cultivation of the present invention is completed. Although the nozzle 1 is arranged linearly to form the planar mat-shaped artificial medium material 13 as shown in FIG. 1, if the nozzle 1 is arranged planarly, the columnar artificial medium material 13 is formed. Material 1
3 can be formed. The artificial medium material 13 is used after being cut into a required shape. If necessary, the cut surface may be sprayed with an emulsion resin adhesive or the like to seal the cut surface.

[0008]

The artificial medium material for plant cultivation of the present invention is as described above, and since the three-dimensional reticulate body 12 holds the soil 4 and acts as a container, the conventional container becomes unnecessary and the shape of the container becomes unnecessary. Therefore, there is an effect that the cultivation form and the display form of the plant can be expanded more widely. That
In particular, the artificial culture medium material of the present invention has a line outside the three-dimensional reticulate body.
The line density is high and the inner line density is low,
Medium soil with a small grain size is used in the inner part, and grain size is used in the outer part.
Since each large soil is filled, the three-dimensional reticulate body
The advantage of being able to prevent the loss of soil from the
is there. It should be noted that the three-dimensional reticulate body 12 may be filled with the soil 4 after forming the three-dimensional reticulate body 12. However, as in the above-described embodiment, the three-dimensional reticulate body 1 is simultaneously replenished with the soil 4 in the process of forming the three-dimensional reticulate body 12.
If it is mixed with 2, the filling work of the soil 4 becomes extremely easy and efficient.
