[0002]

2. Description of the Related Art In recent years, in order to avoid continuous cropping of vegetables and flowers and to avoid soil-borne diseases, or to improve productivity such as uniformity of products, and because it is clean cultivation without using soil,
Due to such factors, the practical application of hydroponics tends to progress rapidly.

This hydroponics does not use soil, but sand, gravel,
Alternatively, it is a cultivation method in which vegetables, flowers, etc. are mainly grown with liquid fertilizer (culture liquid) using rock wool etc. as a medium,
In recent years, various plants have been grown by the hydroponic culture.

As the medium for hydroponics, sand,
In addition to gravel and rock wool, a sponge-like porous material (polyurethane foam 1a) composed of polyol and diisocyanate is molded into a rectangular parallelepiped shape as shown in FIG.
Further, a culture medium 1 is used which is formed by forming lattice-shaped notch grooves 3 in the rectangular parallelepiped polyurethane foam 1a.

[0005] Conventionally, when seeding the medium 1,
As shown in FIG. 7, by sandwiching the seed t with the tip of the tweezers p, burying it in the intersection 3a of the cutout groove 3 of the medium 1, and repeating this, a large number of seeds t are obtained at each intersection. 3a was sequentially buried.

On the other hand, as a soil culture medium, a medium as shown in FIG. 8 has been conventionally known.

The medium (implantation tray 1 ') comprises a main body frame 4 made of synthetic resin or the like, and a plurality of recesses 5 formed in the main body frame 4 in a concave shape so as to accommodate the culture soil g. It is configured.

Conventionally, when seeding the implant tray 1 ', in addition to the method using tweezers as described above, FIG.
Equipment as shown in is used.

The seeding device A comprises the implant tray 1 ',
A receiving box 6 for fitting and holding the implantation tray 1 ', and a suction box 7 connected to a suction unit (not shown) equipped with a blower motor or the like.
And a suction plate 8 having a plurality of suction holes 8a opened at positions engaging with the recessed portion 5 and fitted into the opening 7a of the suction box 7, and suctioned by the suction portion. The seed t adsorbed in the hole 8a is stopped by suction (by opening / closing operation of the valve 9 connected to the suction portion), and the recessed portion 5
It was made to drop on the culture soil g inside.

[0010]

However, the above-mentioned conventional seeding has the following problems.

When seeds sandwiched with tweezers are sown in a medium for hydroponic cultivation, which is formed by forming lattice-like notched grooves in a polyurethane foam, a small seed is sandwiched with tweezers, and Since the detailed work of sequentially burying the seeds in the medium has to be repeated, there has been a problem that the seeding work requires a lot of time and labor.

On the other hand, in the case of sowing using the above-mentioned sowing equipment, it is only a work of dropping the seeds adsorbed in the adsorption holes, and thus, quick and easy sowing is possible. There is a problem that it cannot be used for sowing in a medium for hydroponic cultivation comprising the polyurethane foam or the like.

In other words, by simply dropping the seed into a medium such as a polyurethane foam, the seed is placed on the medium which has elasticity and has a planar shape, and is eventually transported. The seeds on the seeded medium will be scattered around due to a slight impact such as time.

The present invention has been made in view of the above circumstances, and sowing the seeds in a medium for hydroponic culture (seed bed) impregnated with a culture solution so that the seeds can be seeded easily and quickly. A method and a seeding device are provided.

[0015]

Means for Solving the Problems The present invention is a seeding method in which seeds adsorbed in an adsorption hole are dropped into an implantation tray in which a culture soil is stored, and sowing is carried out. The seeds are dropped onto a seed bed which is impregnated with the culture solution through a guide plate having small holes, and thereafter, the insertion rod of the pressing plate is inserted into the small holes to press the seeds. The present invention achieves the above object by providing a seeding method characterized in that seeds are buried in a seed bed.

Further, according to the present invention, a suction box, which is connected to the suction section through a passage, is fitted with a suction plate having a large number of suction holes, and a seed bed impregnated with a culture solution. A guide plate that is interposed between the suction box and the seed bed and has a small hole that engages with the suction hole, and a pressing plate having an insertion rod that is inserted into the small hole. By providing a seeding device, the above object is achieved.

[0017]

The seeding method and the seeding device according to the present invention enable easy and rapid seeding in a medium for hydroponic cultivation.

In other words, the seeds adsorbed in the adsorption holes are dropped onto the seed bed which is a medium, and the seeds are pushed into the seed bed by the insertion rod of the pressing plate, whereby the notch groove formed in the seed bed. The seeds are buried in the intersection of the seeds, and further, sowing is performed on the seed bed for hydroponic cultivation.

It should be noted that the adsorption of seeds is performed by fitting an adsorption plate having an adsorption hole into an opening of an adsorption box which is connected to a suction section, and the seeds do not fall onto the seed bed. This is achieved by stopping the suction unit or closing the suction passage.

The seed is dropped onto the seed bed by guiding small holes opened in a guide plate interposed between the seed bed and the adsorption plate. It works to prevent seed scattering, and further works to prevent seed scattering when pressed by the insertion rod.

Further, the seed pressed and buried in the seed bed by the insertion rod of the pressing plate is not crushed at the time of pressing because the seed bed is made of an elastic member.
