Description

  The present invention relates to a hydroponic cultivation apparatus that stores a culture solution and includes a container having an eye plate portion, and cultivates plants such as sprout by seeding the eye plate portion with seeds.

Hydroponics is a method in which a culture solution is stored in a container, seeds are sown in an eye plate, and a plant is cultivated.
As a hydroponic cultivation apparatus, a common one is a form in which a plate is installed in the middle stage of a deep container. However, in hydroponics, since it is necessary to frequently change the culture solution, it is inconvenient to change the culture solution in the type in which the eye plate is installed in the middle stage of the container.
Therefore, there is a hydroponic cultivation apparatus disclosed in Patent Document 1 as one that can smoothly exchange the culture solution. The device for hydroponics of Patent Document 1 is “a plant that stores a culture solution and a seed support portion having a plurality of through holes on the bottom surface, and can be overlaid with one or more in the container. It is characterized by comprising a planting container ”(see claim 1 of Patent Document 1).
In the apparatus for hydroponics of Patent Document 1, the culture medium is easily replaced by providing the eye plate in a container different from the container for storing the culture liquid.

Utility Model Registration No. 3009115

According to the hydroponic cultivation apparatus disclosed in Patent Document 1, the convenience of exchanging the culture solution is improved, but various problems as described below remain.
(1) Problem 1
Sprouts that need to be softened at the germination stage (growing so that they are not exposed to sunlight) must be placed in a dark room or covered with a light-shielding lid after sowing.
However, conventionally, in the hydroponic cultivation apparatus that is generally used, a container constituting the hydroponic cultivation apparatus is formed of a transparent material so that plant growth can be easily observed. Therefore, in the germination period, a method of shielding light by covering the entire container with a box or the like is employed.
However, such a method has a problem that it does not look good and requires a space for installing a box or the like.
In this regard, Patent Document 1 has no description regarding the translucency of the material of the container, and there is no other prior document considering softening cultivation.
Then, the 1st subject of this invention is the point of how to comprise the apparatus suitable for softening cultivation.

As shown in the enlarged view of the circled portion in FIG. 4, the through hole 9 provided in the eye plate portion 3 has a shape that increases in diameter downward. Since the diameter of the upper surface side of the eye plate portion 3 is smaller than the diameter of the lower surface side of the through hole 9, the seed 8 is difficult to enter the through hole 9. On the contrary, since the area of the edge of the through-hole 9 is small on the lower surface side, when the lower part of the upper container 5 is inserted into the lower container 7 and installed, the influence of surface tension is alleviated, and the culture solution 6 is passed through the through-hole. 9 is easy to pass, and can be installed smoothly. Here, the diameter expansion means that the cross section gradually expands as it goes downward.
In addition, the size of the opening on the inner surface side of the through hole 9 is set such that the seed 8 does not pass down.
