Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cultivation pot for growing plants in a hydroponic cultivation tank.

In general, a hydroponic system uses a cultivation pot that is almost fixed in a cultivation tank filled with a nutrient solution, fills this cultivation pot with medium material such as gravel, sows seeds in this medium, and allows them to germinate and then grow. Measures are being taken. Since the cultivation pot of this type of device is almost fixed, the water level in the cultivation tank must be controlled to be constant at all times, which is cumbersome to operate. Furthermore, for example, soft vegetables and sprouted vegetables require labor to bind after harvesting, and furthermore require packaging boxes for shipping, which is undesirable from a logistics point of view.

The present invention has been made with the above-mentioned problems in mind, and aims to eliminate the need for water level adjustment in cultivation tanks and to improve the physical distribution of harvested plants.

In order to achieve the above object, the basic structure of the cultivation pot for hydroponic cultivation of the present invention is to form a container-shaped cultivation pot body with a substance that floats on water, and to form a bottom plate with a raised bottom. A hole is provided and a culture medium member is assembled on the bottom plate so that when it is floated on water, the water level is above the bottom plate.

With this configuration, the water level remains constant with respect to the cultivation pot despite fluctuations in the liquid water level, allowing good plant cultivation, and the cultivated plants can be distributed for each cultivation pot. It is effective.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a cultivation pot body, which is a molded product made of a material with a specific gravity of less than 1, such as styrene foam or polyethylene with a low expansion ratio, and is formed into a hollow container shape.

This cultivation pot main body 1 has a bottom plate 2 at a certain height from the lower end, that is, it is formed with a raised bottom. A plurality of holes 3 are formed in the bottom plate 2, on which a culture medium member 4 made of a water-absorbing material such as fiber scraps and foamed urethane can be freely placed. Furthermore, the cultivation pot body 1 has a stacking utility part 6 formed at the upper edge. In this example, the stacking step 6 is fitted to the lower rim of another cultivation pot main body 1 as shown in FIG. 2, but the stacking step 6 is formed on the lower rim. Then, add this to the other cultivation pot body 1
It may be fitted onto the upper lip of the. As shown in FIG. 3, this cultivation pot body 1 is floating in a nutrient solution 7 of a cultivation tank 6, and at this time, the water level of the nutrient solution 7 determines the specific gravity of the body 1.

The cultivation pot for hydroponic cultivation with the above configuration is as shown in Figure 3.
The plant 8 is cultivated floating in the cultivation pot body 1.
There is a substantially constant relationship between the water level of the nutrient solution 8 and the water level of the nutrient solution 8, so even if the water level of the nutrient solution 8 fluctuates on the cultivation tank 6 side, there is no problem in cultivating plants.

Further, as shown in FIG. 2, the plants 8 can be shipped while being planted in the culture medium member 4, and at this time, the plants 8 can be kept in an active state by the water retention function of the culture medium member 4. Moreover, there is no need for work such as tying the plants together, and in addition, the cultivation pot itself
functions as a transport case, which is advantageous from the viewpoint of logistics, and the cultivation pot bodies 1 can be stacked, making the above-mentioned logistics more effective.

FIG. 4 shows another embodiment of the present invention, in which a rib 9 is provided on the top surface of the bottom plate 2 of the cultivation pot main body 1, and the culture medium member 4 is divided into a plurality of pieces, so that the harvest amount can be divided into small units. It is made so that it can be divided into parts and brought out from Jim.

As explained above, the cultivation pot for hydroponic cultivation of the present invention is of great value because it facilitates the cultivation of plants and makes it convenient for distribution.
