Embodiments will be described below 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. This artificial medium material 13 for plant cultivation has a flat mat-like shape and is cut to a size that fits in the frame 14, and the artificial medium material 13 is sown with seeds of plant B or planted with seedlings. As shown in FIG. 1, when it grows to a state suitable for ornamentation, it is attached to the frame 14 and hung on the wall as shown in FIG.

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. Further, the powdery granular soil 4 is dropped from the pipe 3 arranged at a required position between the nozzles 1 at the same time when the filament 2 naturally descends. 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 arranged 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 folding the filaments 2. And the contacts are adhered to each other by utilizing their adhesiveness. 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 precooling is sandwiched 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 folded again by the air injection nozzle 5 to adjust the final density. 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 soil is 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 planar mat-shaped artificial medium material 13 as shown in FIG. 1 is formed by arranging the nozzles 1 linearly, if the nozzles 1 are arranged planarly, the columnar artificial medium 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 net body 12 surely holds the soil 4 and plays a role of a container, the conventional container becomes unnecessary. The effect of being freed from the restriction due to the shape of is, therefore, there is an effect that the cultivation form and the display form of the plant can be expanded more widely.
Although the soil 4 may be filled into the three-dimensional net body 12 after the three-dimensional net body 12 is formed, as in the above-described embodiment, the three-dimensional net body 1 is formed.
If the soil 4 is simultaneously mixed with the three-dimensional net body 12 in the process of forming 2, the filling operation of the soil 4 becomes extremely easy and efficient.
