Description

[Detailed description of the invention] Industrial application field This invention allows the culture solution supplied from the nutrient solution pipe to be moistened in a moisture-containing bag, which efficiently absorbs the culture solution to germinate and grow plants. Along with
The present invention relates to a hydroponic cultivation device capable of forcibly supplying an appropriate amount of oxygen to the roots of plants to further promote their growth.

Prior Art Conventionally, hydroponic cultivation devices that allow the culture solution supplied from a nutrient solution pipe to be moistened in a moisture-containing bag, which efficiently absorbs the culture solution to easily germinate and grow plants, were developed prior to the filing of this application, for example. This device is described in Japanese Utility Model Publication No. 48-37707, and as shown in FIG. The above-mentioned nutrient solution pipes 1 and 2 are formed so that the seeds of plants can be sown in a mounted state or the stem culms of growing plants can be elastically held by pasting elastic materials 2, 2 such as 1
A moisture-containing bag 3 whose both end edges 3a, 3a are wrapped and whose middle part hangs down in the form of a bag below the center of both nutrient solution pipes 1, 1 is provided, and the two nutrient solution pipes 1, 1 are
A number of holes 4 are perforated in each of the holes 4 so that the culture solution flowing out from the holes 4 can be moistened in the moisture bag 3,
Both ends of the outer case body 5 are fixed to the two nutrient solution pipes 1, 1 to cover the surroundings, and the bottom of the outer case body 5 is tilted to one side so that the culture solution dripped from the moisture bag 3 is placed on one side. It is constructed so that water can flow down towards the soil, allowing plants to germinate and grow.

Problems that the invention aims to solve By the way, in conventional hydroponic cultivation devices of this type, the outer case body was integrated so that it could not be divided into left and right sides, so it was difficult to prepare for insertion of a moisture bag, etc. The drawback is that it takes a lot of time to prepare, or it takes more time than necessary to pull out the swollen roots during harvesting, but the supply of oxygen to the roots is insufficient, which causes root rot and prevents the plants from growing properly. It was hot.

Means for solving the problem The present invention solves the above problems, and includes:
The contents will be explained below with reference to FIGS. 1 and 2 corresponding to the embodiment. That is, inside a cultivation container 101 configured to be able to be divided into left and right parts, a moisture bag 102 whose upper end is wrapped around the left and right nutrient solution pipes 103, 103, respectively, is stored, and the moisture bag 102 is wrapped around the left and right nutrient solution pipes 103, 103, respectively. The supplied culture solution is moistened in the moisture bag 102. A moisture bag 102 is placed at the bottom of the culture container 101 configured as described above.
A water collecting pipe 104 capable of collecting excess culture solution dripped is removably suspended.

In the water collection pipe 104 described above, there is a cultivation container 101.
An oxygen supply pipe 105 is provided to forcibly supply oxygen to the moisture bag 102 housed inside.

Function First, at the start of hydroponic cultivation of plants, the cultivation container 101 is divided into left and right parts about the connecting part with the water collection pipe 104 as an axis. Next, after storing the moisture-containing bag 102 whose upper end is wrapped around the nutrient solution pipes 103, 103, respectively, in the divided cultivation container 101, the cultivation container 101 is integrally connected, and the moisture-containing bag 102 is placed inside the divided cultivation container 101. At the same time as seeding, both nutrient solution pipes 103, 103
If a smaller amount of culture solution is supplied to the moisture bag 102,
The moisture-containing bag 102 moderately absorbs the culture solution and becomes moist, and the excess culture solution is dripped from the moisture-containing bag 102 into the water collection pipe 104 and collected and drained.

On the other hand, oxygen is forcibly supplied to the moisture bag 102 from the oxygen supply pipe 105.

After a certain period of time, the seeds will germinate and absorb the culture solution moistened in the moisture bag 102 and oxygen supplied from the roots, causing root rot due to lack of oxygen. It grows smoothly.

Once the plants have grown to a predetermined size, the supply of culture solution and oxygen is stopped, and then the cultivation container
01 can be divided into left and right parts as described above, and densely grown plants or plants with enlarged growing parts can be easily taken out and collected.
