Description

  TECHNICAL FIELD The present invention relates to a nursery for use in plants to be subjected to hydroponic culture.

  In hydroponic culture, although there is also a patent document 3 below, a cultivation pallet 2 having a hole 3 as a planting hole is installed as a lid in a water tank 1 as shown in FIG. The seedling 5 is set in the hole 3 together with the seeding medium 4.

In addition, there exists a thing shown below as prior art literature regarding hydroponic cultivation.
Unexamined-Japanese-Patent No. 9-140283 (invention of the support structure which prevents the fall of a plant) Unexamined-Japanese-Patent No. 7-289095 (invention of the support structure which prevents the fall of a plant) Japanese Utility Model Application Publication No. 59-052856 (invention for fixing a seeding culture medium) Utility model registration 307,473 (invention to prevent root involvement during planting)

  In the plant to be subjected to the hydroponic culture shown in FIG. 4 described above, if the planting density (the number of seedlings per area) is high, as in the case of production in a plant factory using so-called artificial light, the seedlings adjacent to the seedlings before planting. The roots of 5 tend to be entangled, and when the side axis is opened horizontally, the leaves 6 of adjacent seedlings 5 are likely to interfere. Moreover, since it is not possible to carry out soiling like outdoor cultivation, the support of the hypocotyls 8 of the seedlings 5 themselves is insufficient and they are prone to fall.

  In addition, due to the arrangement, the upper half of the seeding culture medium 4 is exposed to cultivation light during the entire period of raising seedlings, which causes the generation of algae. The occurrence of algae is undesirable because it tends to lead to contamination of the entire cultivation apparatus and causes disease.

  Particularly in the late rearing stage, the growth of the seedlings 5 germinated from the seeding culture medium (urethane cube) 4 is remarkable, and the roots 7 are entangled with the adjacent seedlings 5 and the overlapping of the leaves 6 is almost inevitable.

  This is an obstacle to taking out the individual seedlings 5 at the time of planting, and is undesirable because it causes the seedlings 5 to be injured by unreasonable separation. Furthermore, the overlapping of the leaves 6 makes the light hitting the seedlings 5 uneven, which leads to the variation of the growth rate of the seedlings 5 at a remarkable growth stage.

  Also in the late rearing stage, since the growth above with respect to the hypocotyl 8 becomes large, the seedlings 5 are particularly prone to fall from the relationship of the center of gravity. When the seedlings 5 fall down, they are not desirable because they impair the quality.

  The seeding culture medium (urethane cube) 4 in the seedling is inserted into the hole 3 opened in the cultivation pallet 2 and held. Therefore, at the time of planting, the seeding medium 4 is removed from the hole 3 and re-inserted and fixed to the same hole 3 of the cultivation pallet 2 of the newly planted place every growing seedlings. At this time, if the root 7 is widely opened, the operation is difficult because the insertion is made from a small hole compared to the size of the opening of the root 7.

  The said patent documents 1, 2 and 4 are not related to the water tank 1 provided with such a cultivation pallet 2, and do not become a solution of the said problem.

  Further, Patent Document 3 is a holder for a nursery bed used by inserting it into the planting hole of the lid of the hydroponic culture tank and suspending it on the lid, and (1) in order to suspend it on the lid (2) when it is inserted. The lower part in contact with the culture solution has an opening that does not prevent the roots from extending out of the holder and has a strength sufficient to hold the nursery bed, and (3) the nursery bed is in close contact with the inside of the holder However, there is no prevention of attraction of algae, nor entanglement of roots with adjacent seedlings, nor prevention of overlapping of leaves.

  Furthermore, in patent document 3, since the upward growth with respect to the hypocotyl 8 becomes large, the countermeasure against becoming easy to fall down the seedling 5 from the relationship of gravity center is not made.

  The object of the present invention is to solve the problems of the conventional example, to prevent the whole seedling from falling down, to stably support the seedling in growing seedlings, and to prevent the root tangency and the interference between leaves of adjacent seedlings. It is to provide a nursery holder.

It is a perspective view showing one embodiment of a raising seedling holder of the present invention. It is an expanded view which shows one Embodiment of the raising seedling holder of this invention. It is a vertical side view which shows a prior art example.

  Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. 1 is a longitudinal sectional side view showing an embodiment of the seedling-growing holder according to the present invention, FIG. 2 is a perspective view of the same, and FIG. 3 is a developed view of the same. FIG. 3 is a development view of the same. Although it is installed, it is a raising seedling holder for setting the seedling 5 of the plant planted in the seeding culture medium 4 by the urethane cube together with the seeding culture medium 4.

  The seedling-growing holder 10 is composed of an inner cylinder 11 and an outer cylinder 12 as a double cylinder having portions where the cylinders overlap each other.

  The inner cylinder 11 and the outer cylinder 12 are both a megaphone-like cylinder whose diameter is larger than that of the other side of the open ends at both ends, and the outer cylinder 12 is located above the inner cylinder 11 Slideably fit.

  After sliding, the outer cylinder 12 that can slide upward is fixed to the inner cylinder 11 by friction due to the difference in cylinder diameter.

  The seedling culture medium (urethane cube) 4 for fixing the seedlings 5 is accommodated in the inner cylinder 11 and the locking portion 13 for holding the seeding culture medium is formed on the inner surface. The locking portion 13 is a stopper (tab) for preventing the seeding culture medium from moving, and is formed as a protrusion continuous in the circumferential direction of the inner surface of the inner cylinder 11 or as a discontinuous protrusion.

  The outer surface of the inner cylinder 11 is provided with a support 14 for holding the cylinder at a predetermined height in the vertical direction when the cultivation pallet 2 is attached, and for preventing the whole cylinder from tipping over.

  The support 14 can also be formed as a claw, and is formed as a circumferentially continuous ridge or as an intermittent projection.

  The claws that make up the locking portion 13 and the support 14 need only be hooked in the holes of the culture tray and the inner side with the seeding medium, so there are three or more partial bumps in the circumferential direction in terms of center of gravity balance. The shape is not particularly limited if it exists.

  Furthermore, as a material of which the inner cylinder 11 and the outer cylinder 12 are made, a metal such as plastic resin or stainless steel which is hardly corrosive from the viewpoint of hygiene is adopted, and the ease of molding integrally forming the locking portion 13 and the support 14 or Resin is preferable from the viewpoint of cost.

  Further, if the inner cylinder 11 or the inner cylinder 11 and the outer cylinder 12 are shielded from black or the like, since the seeding culture medium 4 is covered with a black cylinder, the seeding culture medium 4 is shielded from light to provide an algal protection effect.

  In addition, it is also possible to make the outer cylinder 12 transparent or semitransparent to ensure the light collecting property.

  Next, usage will be described. The seedling-growing holder 10 stores a seeding culture medium (urethane cube) 4 for fixing the seedlings 5 in the inner cylinder 11. At that time, since the seeding culture medium 4 is urethane, if it is pressed, it can be hooked to the locking portion 13 so as not to move.

  If the inner cylinder 11 is inserted into the hole 3 of the cultivation pallet 2 of the water tank 1 and the support 14 is hooked in the hole 3, it is held at a predetermined height in the vertical direction and the whole cylinder is prevented from falling over it can.

  In the second half of the seedling raising period, the inner cylinder 11 arranges the leaves 6 and roots 7 in a range that does not interfere or entangle with the adjacent seedling seedlings, so that the contact of light during seedling raising is uniform and the seedling growth is uniform. In addition, the seedlings are not damaged when taking out the seedlings 5 at the time of fixed planting.

  Furthermore, the whole seedling can be supported via the leaves 6 simultaneously with the above-described effect of putting together the leaves 6 by extending the outer cylinder 12 upward in the second half of the seedling raising.
