Description

[Detailed description of the invention] [Industrial field of application] This invention is a method of cultivating vegetables, fruits, and other crops by floating them in a nutrient solution or water in a plant cultivation house made of transparent material. This relates to planting boards used for cultivation.

[Conventional technology]

Conventionally, in hydroponic cultivation, the seeds of the cultivated product are sown in a nursery bed made of polyurethane foam, etc., and then germinated.
After raising the seedlings to a certain extent, as shown in FIG.
The cultivated product 1 is transplanted onto the planting board 3 by fitting the planting board 3 into the bed 5 filled with the nutrient solution 4.
Cultivation was carried out either by placing the planting plate 3 on top of the nutrient solution 4 or by floating the planting board 3 directly on the nutrient solution 4 (Jet-kai 59-
(See Publication No. 52856).

[Problem to be solved by the invention] However, in this case, there is not only the complexity of having to transplant the cultivated product 1 into the planting hole 3a of the planting board 3 after completing sowing and raising the seedlings, but also the need for transplanting. Cultivation 1 was easily damaged. Furthermore, conventional hydroponic cultivation has had the problem of requiring a large space not only for cultivation on the planting board 3 but also for germination and seedling raising before transplanting to the planting board 3.

[Means to solve the problem]

In order to solve the above-mentioned problems, the planting board for hydroponic cultivation according to the present invention has a planting board main body provided with planting holes penetrating in the thickness direction, and a small hole at the bottom through which the roots of the cultivated plants pass. The present invention is characterized by comprising a cultivated product holding container which is provided in the planting hole and is detachably attached to the planting hole so that its bottom is located above the bottom of the planting hole.

[Effect]

When performing hydroponic cultivation using the above-mentioned planting board for hydroponic cultivation, seeds of the cultivated product are sown in the cultivated product holding container with the cultivated product holding container attached to the planting hole of the planting board main body, Germinate the cultivated material within the cultivated material holding container. Seedlings of the germinated plants and subsequent cultivation are then continued on the planting board main body. In this way, in this invention, the sowing and raising of seedlings of cultivated products are also carried out on the planting board itself, so there is no need to transplant the cultivated products, which not only saves labor in hydroponic cultivation but also reduces the need for transplanting The accompanying damage to cultivated plants will also no longer occur.

In addition, when germinating and raising seedlings of cultivated products, the temperature and/or
Alternatively, germination and seedling raising can be carried out by adjusting the humidity, making it possible to reduce the space required for germination and seedling raising.

By the way, since the bottom of the cultivated product holding container is located above the bottom of the planting hole in which it is attached, a space exists within the planting hole below the cultivated product holding container. When germinating and raising seedlings of the cultivated product, the roots of the cultivated product pass downward through the small holes provided in the cultivated product holding container and grow in the space below the cultivated product holding container. On the other hand, the bud or stem portion of the cultivated product grows within the cultivated product holding container. In addition, when germination and seedling raising are carried out by stacking multiple planting boards, the roots of the plants on each planting board do not contact the planting board adjacent below, and the sprouts of the plants on each planting board do not touch. The stacked planting boards are separated and floated individually on the bed at a time when the stem part does not come into contact with the planting board adjacent to the top.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

As shown in FIG. 2, the planting board 10 for hydroponic cultivation (hereinafter simply referred to as the planting board 10) according to the present invention includes a rectangular planting board main body 11 made of expanded polystyrene or the like. The main body 11 has a plurality of planting holes 11a having a circular cross section that penetrate in the thickness direction.

As shown in FIG. 1, each planting hole 11a is made of a non-foamed synthetic resin such as non-foamed polypropylene, polyethylene, polystyrene, etc., and has a substantially cylindrical shape with an open upper end and a bottom at the lower end. The cultivated product holding container 12 can be detachably attached from above. The cultivated product holding container 12 is formed so that its diameter gradually decreases from the upper end toward the lower end, and the diameter gradually decreases from the upper end toward the lower end in correspondence with that of the planting hole 11a. Note that the diameter of the cultivated product holding container 12 and the diameter of the planting hole 11a may be constant from the upper end to the lower end.

A circular flange 12a that projects outward in the radial direction is provided at the upper end of the cultivated product holding container 12, and when this flange 12a engages with the upper surface of the planting board main body 11, the cultivated product holding container 12 It is prevented from sinking into the planting hole 11a. The height of the cultivated product holding container 12 is set to be smaller than the thickness of the planting board main body 11, so that the cultivated product holding container 1 can be opened while the cultivated product holding container 12 is attached to the planting hole 11a.
A space 13 having a predetermined height is left within the planting hole 11a below the hole 2.

As shown in FIG. 3, the bottom of the cultivated product holding container 12 is formed into a mesh shape by providing a plurality of rectangular small holes 12b, 12b, . . . . Each small hole 12b does not allow seeds 14a of a cultivated product 14, which will be described later, to pass therethrough, but is made large enough to allow the roots of the cultivated product 14 to pass through.

When performing hydroponic cultivation using the above-mentioned planting board 10, as shown in FIG. Seeds 14a of the cultivated product 14 are sown in the material holding container 12. Next, as described above, a plurality of planting boards 10 on which seeds have been sown are stacked in the cultivated product holding containers 12, 12, etc., and germination (not shown) in which the internal temperature and humidity can be adjusted as necessary. The seeds are placed in containers for germination and seedling growth to some extent. At this time, as shown in Figure 4b,
The roots of the cultivated product 14 that have sprouted pass through the small hole 12b of the cultivated product holding container 12 and grow in the space 13 below the cultivated product holding container 12 in the planting hole 11a, while the sprouts of the cultivated product 14 and The stem portion grows within the cultivated product holding container 12. In addition, planting board 1
0, 10... are in a stacked state, sufficient oxygen is supplied to the roots of the cultivated plant 14 through the space 13.

Thereafter, when the cultivated plants 14 have germinated and grown to a certain extent, individual planting boards 10 are floated on the nutrient solution 16 in the bed 15, as shown in FIG.
4. Perform hydroponic cultivation. In this way, the time to separate the stacked planting boards 10 and start hydroponic cultivation individually is when the root part of each cultivated plant 14 on the stacked planting boards 10 is adjacent to the bottom of the planting board 10 or its planting board 10. The period at which the buds or stems of each cultivated product 14 do not start to conflict with the cultivated products 14 on the board 10 and the cultivated products 14 on the adjacent planting board 10 above do. In addition, each planting board 10
Harvesting after floating on the bed 15 for hydroponic cultivation can be easily performed by pulling out the cultivated product holding container 12 from the planting hole 11a.
