Description

  The present invention relates to a seedling box that can be, for example, a flooded / irrigated type.

  As a conventional seedling box, one having a rectangular bottom wall in plan view and having side walls rising from the four sides of the bottom wall is often used.

  And regarding the said conventional seedling box, the further space-saving is desired in the case of arranging a plurality of seedling boxes.

  The present invention has been made in consideration of the above-described matters, and an object thereof is to provide a seedling box that can surely save space.

In order to achieve the above object, a seedling box according to the present invention is a seedling box having a bottom wall and a side wall rising from an edge of the bottom wall, and is adjacent when a plurality of the seedling boxes are arranged. A mating part is provided at the edge of the bottom wall so that the seedling boxes are fitted with each other through a boundary portion between adjacent seedling boxes. The side wall is formed in a shape in which a portion of the side wall is not formed so that a region where the side wall does not exist is formed in the boundary portion of the box, and further, in one of the boundary portions in the bottom wall, A convex portion projecting outward is provided with a concave portion recessed inwardly on the other side. The convex portion and the concave portion constitute the fitting portion, and a plurality of the bottom wall are provided on the bottom wall. The bottom wall of the bottom wall protrudes downward. And a plurality of legs provided for, the through hole is formed of a long hole formed to extend in a direction to male and female mating (claim 1).

You may use the said seedling box for submerged cultivation (Claim 2 ).

  In the present invention, a seedling box capable of surely saving space is obtained.

  That is, in the seedling box of the invention according to each claim of the present application, a fitting portion is provided at the edge of the bottom wall so that when a plurality of seedling boxes are arranged, adjacent nursery boxes are fitted with each other. As compared with the conventional seedling boxes that do not fit male and female in this way, it is advantageous in terms of space saving when arranging a plurality of seedling boxes, and as the number of seedling boxes arranged increases, the advantage of this space saving is Become prominent. Moreover, since the area | region where a side wall does not exist is formed in the boundary part of the adjacent nursery box when arranging a plurality of seedling boxes, water flow performance can be improved through this area.

BRIEF DESCRIPTION OF THE DRAWINGS (A)-(H) is a figure which shows schematically the structure of the seedling box which concerns on one embodiment of this invention, (A) is a rear view, (B) is a left view, (C) is a plane (D) is a sectional view taken along line DD of (C), (E) is a bottom view, (F) is a sectional view taken along line FF of (C), (G) is a front view, and (H) is a sectional view. It is the H section enlarged view of (C). It is sectional drawing which shows schematically the structure of the cultivation bed in which the said seedling box is mounted.

  Embodiments of the present invention will be described below with reference to the drawings.

  The seedling box according to the present embodiment can be used for both flooding and irrigation, and as shown in FIGS. 1 (A) to (H), the bottom wall 1 having a substantially rectangular shape in plan view, And a side wall 2 rising from the edge of the bottom wall 1.

  And the fitting part 3 is provided in the edge part of the bottom wall 1 so that when a plurality of seedling boxes are arranged, the adjacent seedling boxes are fitted with each other. More specifically, as shown in FIG. 1 (E), one of two opposing sides (long side in this example) of the bottom wall 1 has a convex portion 4 protruding outward, and the other has A concave portion 5 that is recessed inward is provided, and the convex portion 4 and the concave portion 5 constitute the fitting portion 3.

  Further, the side wall 2A provided inside both ends of the convex portion 4 and the side wall 2B provided outside both ends of the concave portion 5 are configured to be fitted together when the convex portion 4 and the concave portion 5 are fitted. ing. That is, the fitting part 3 is also configured by a part of the side wall 2 (side walls 2A, 2B).

  And as shown in FIG.1 (C), although the side wall 2 is provided over the two sides (short side) without the convex part 4 and the recessed part 5 among the four sides of the bottom wall 1, it is a convex part. 4 and the two sides (long sides) having the recesses 5 are provided only partially (only the portion protruding outward). Therefore, in the conventional seedling box in which the side walls 2 are provided over the entire four sides of the bottom wall 1, two (double) side walls that always exist at the boundary part of adjacent seedling boxes when a plurality of seedling boxes are arranged. However, the seedling box of this example is designed to improve space saving by avoiding duplication of the side wall 2 at least at the part (long side) where the male and female are fitted when arranging a plurality of seedling boxes. As the number of seedling boxes arranged increases, the advantage of this space saving becomes more remarkable.

  Moreover, the seedling box of this example is in a state in which a solid medium (for example, urethane medium, rock wool medium, etc.) not shown is placed inside, for example, the cultivation bed 7 whose entire upper surface is covered with the waterproof film 6. (See FIG. 2). And when using a seedling box in this way, high water flow performance may be calculated | required by the seedling box.

  In this regard, in the seedling box of this example, the side wall 2 is partially cut away so that a region where the side wall 2 does not exist is formed at the boundary portion between adjacent seedling boxes when a plurality of seedling boxes are arranged. Since the side walls 2 are not provided over the entire four sides of the bottom wall 1, the water flow between the seedling boxes in a state where a plurality of the seedling boxes are arranged is performed without stagnation.

  Moreover, since the bottom wall 1 of the seedling box of this example is provided with a plurality of through holes 8, and the bottom surface of the bottom wall 1 is provided with a plurality of legs 9 that protrude downward, the bottom wall The bottom surface of 1 can be lifted from the ground (the mounting surface of the cultivation bed 7), and thus the water flow performance from the bottom surface to the top surface of the bottom wall 1 can be improved.

  And, by carrying out liquid-type cultivation (cultivation in which germination process etc. is carried out with the liquid) using such a seedling box, for example, the dissolved oxygen concentration and nutrient components It is possible to expect an effect that the whole is leveled and variation in seedling growth is reduced.

  By the way, in the conventional nursery box, the seedlings in the central part of the bottom wall grow vigorously, and the seedlings in the peripheral part tend to be small. It can be considered that this tendency is caused by the fact that the competitive effect of plants does not work so much at the peripheral edge of the bottom wall 1. Or about the said tendency, in the peripheral part of the bottom wall 1, it may be considered that it is influenced by the radiant heat and reflected heat by the side wall 2, and heat is accumulate | stored more easily than the center part of the bottom wall 1. it can. And in any case, in the seedling box of this example, the side wall 2 does not exist over the entire four sides of the bottom wall 1, so that the prosperous growth of the seedling over a wide range is expected. Can do. And the expectation for this thriving prosperity is heightened also by having made the side wall 2 whole low (to the height of about 1-2 cm).

  The seedling box in this example is molded from rigid foamed polystyrene, but the material for the seedling box can be selected according to its use, etc. May be. Moreover, you may make it make the seedling box of this example respond | correspond to pot seedling raising.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  In the example shown in FIG. 1, the fitting part 3 is provided only on the long side of the bottom wall 1. However, the present invention is not limited thereto, and the fitting part 3 is provided only on the short side of the bottom wall 1. You may provide the fitting part 3 in both a long side and a short side. The position where the fitting portion 3 is provided is not limited to the vicinity of the end of each side of the bottom wall 1, and may be, for example, near the center of each side of the bottom wall 1.

In the example shown in FIG. 1, an example in which one convex portion 4 exists on one of the two long sides of the bottom wall 1 and one concave portion 5 exists on the other side is not limited to this. , two or more projections 4 or recesses 5 may be set only to the respective sides.

  In the example shown in FIG. 1, the side wall 2 is provided over the entire two short sides of the bottom wall 1, but this is not limiting, and the side wall 2 provided on the short side of the bottom wall 1 is partially cut away. It is good also as a shape.

  Needless to say, the above modifications may be combined as appropriate.
