Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cultivation holder for hydroponic cultivation, which is used in combination with a planting panel floating on the surface of a culture solution. .

[Conventional technology]

One method of cultivating plants is hydroponic cultivation, which uses a culture solution instead of soil to supply necessary components to plants.

In the above hydroponic cultivation, crop seeds are raised,
A crop holder is used to hold the seedlings.

Conventional crop holders use urethane chips or rock wool with high porosity to ensure that sufficient nutrients are supplied to crops. An appropriate number of seeds are sown into such a cultivation container. This sowing is carried out by pushing the seeds one by one into urethane chips or rock wool so that the seeds are stably held at the sowing position. Once the crops have grown to a certain extent in such a cultivation container,
The cultivated product holders are divided into individual crops, which are transplanted to planting panels floating on the surface of the culture solution, and grown until they can be shipped as products. This planting panel is provided with through holes at intervals such that adjacent crops do not touch each other in anticipation of the horizontal spread of the growing crops at the shipping stage. The plants are transplanted by pushing in the cultivated plant holders and placing them in place. After transplanting, when the crops grow, they are pulled out and harvested together with a cultivation holder made of urethane chips or the like that is pushed into the holes in the planting panel, and then packaged in bundles and shipped.

[The problem that the idea aims to solve]

However, in the conventional cultivated product holder as described above, in order to stably hold the sown seeds, it is necessary to push the seeds into urethane chips or rock wool, making the sowing operation complicated.
In addition, when the crop holder is divided into individual crop units and transplanted to the planting panels once the crops have grown to a certain extent, it is necessary to be very careful not to damage the crops. It is. In addition, when harvesting a grown crop, in order to pull out the crop holder made of urethane chips or the like that is pushed into the hole in the planting panel, for example, grasp the stem of the crop directly with your hand and apply force. In addition, a pulling operation is required, and great care must be taken to avoid damaging the crops during this operation.

As described above, with conventional cultivated crop holders, seeding work is complicated, and even during the process from transplanting to shipping, great care must be taken not to damage the crops. Since it is necessary to do this while brushing, the work becomes complicated, and as a result, a problem arises in that it requires a lot of effort and time.

The present invention was made in order to solve the above-mentioned problems, and provides a cultivated product holder for hydroponic cultivation that can easily carry out operations from sowing crops to harvesting them after they grow and shipping them. The purpose is to

[Means to solve the problem]

In order to solve the above-mentioned problems, the cultivation product holder for hydroponic cultivation according to the present invention is removably inserted into a through-hole formed in a planting panel that floats on the surface of a culture solution, and also holds crop seeds. It has a holding part made of foamed resin with a V-shaped cross section for holding, germinating and growing, and a notch of a size that does not allow crop seeds to pass through is formed at the bottom of the holding part, while
A flange is integrally provided on the upper edge side of the holding part in a shape that spreads laterally so that it comes into contact with the top surface of the planting panel from above and is locked when the holding part is inserted into the through-hole of the planting panel from above. In addition, the brim is characterized by being provided with a thick reinforcing portion that protrudes upward at a portion of the brim that extends toward the upper edge of the holding portion.

[Function] In the cultivated product holder for hydroponic cultivation having the above configuration, by introducing the crop seeds from above into the holder having a V-shaped cross section, the seeds are stably arranged at the bottom of the holder. Seeding work becomes easier.

In addition, when assembling to the planting panel, insert the holding part from above into the through-hole of the planting panel until the collar provided on the upper edge of the holding part comes into contact with the top surface of the planting panel and is locked. This can be done with an extremely simple task. In such a mounted state, nutrients from the culture solution are supplied from the notch formed at the bottom of the holder, and the stems after germination grow while being supported by the V-shaped side wall of the holder.
On the other hand, the root portion passes through the notch and enters the culture medium to continue growing.

After the crops have grown, the cultivated product holder is placed on the planting panel with the brim touching it from above, so pull up the holding part by holding the brim, and then grasp the outer peripheral surface of the holding part. The crops can then be harvested by pulling up the cultivated product holder together with the grown crops through the through hole of the planting panel.

In addition, when pulling up by holding the brim as described above, stress concentration occurs at the position where the brim connects with the upper edge of the holding part, but this part is reinforced by a thick reinforcing part. Therefore, the lifting operation can be carried out without requiring excessive care not to cause cracks or the like in the cultivated product holder itself.

Furthermore, at the initial stage of lifting work as described above, the brim is in close contact with the top surface of the planting panel, so first create a gap in the above-mentioned contact surface and insert your hand under the brim. This is necessary. At this time, since the reinforcing part has an upwardly protruding shape, it is possible to grasp this part with the fingertips and pull it up, thereby creating a gap between the brim and the planting panel. Therefore, in order to create the above-mentioned gap, for example, it is necessary to hold the stem of the crop and pull it up, or prepare a separate pointed tool and insert it between the brim and the planting panel. No other work is required. As a result, crops can be left untouched.
Harvesting work as described above can be easily performed.

In addition, after harvesting the crops together with the cultivation holder as described above, by packaging them together and shipping them, you can avoid damaging the crops as much as possible and reduce the work required from sowing to shipping. The entire process can be made easier.
