Description

Hydroponic cultivation system for low-potassium vegetable cultivation {HYDROPONICS SYSTEM FOR PRODUCTION OF LOW-POTASSIUM CONTENT VEGETABLE}

The present invention relates to a hydroponics apparatus for growing low-potassium vegetables.

In general, renal failure patients cannot excrete potassium well because the kidney's ability to excrete potassium is reduced. As a result, there is a risk of developing hyperkalemia, which can lead to arrhythmias and, in severe cases, cardiac arrest. Therefore, although it depends on the stage of chronic kidney disease, it is necessary to limit the daily potassium intake to 1,500 to 2,000 mg or less for renal failure patients. Since potassium is contained in many foods, kidney disease patients need to be careful about protein and salt intake, and be careful about potassium intake.

As is well known as one of the three elements of plants, potassium is essential for the growth of plants and is necessarily contained in vegetables. Therefore, it is required to provide vegetables with a low potassium content for kidney disease patients. Vegetables with low potassium content are realized by cultivating low-potassium vegetables with a standard nutrient solution containing potassium and then cultivating them with a standard nutrient solution containing no potassium.

In the conventional low-potassium cultivation method, after growing vegetables in a potassium-containing standard nutrient solution cultivation housing containing potassium, a standard nutrient solution containing no potassium is added to grow again. As such, there is an inconvenient problem that the plant has to be moved from the housing containing potassium to the housing containing no potassium, and in the state that the plant is not moved, the user withdraws the standard nutrient solution containing potassium from the first housing and then again without potassium. The process of filling the standard nutrient solution should be repeated. In this case, there is a problem in that the cultivation time is delayed and the productivity is lowered due to excessive labor costs.

In addition, when the seedlings are seated in the cultivation port 300 , the solid medium may be in close contact with the root portion of the seedlings.

When a plant in a seedling state positioned in the first accommodating space S1 goes through a growing season and a harvest season, it may be positioned in the second accommodating space S2. For example, in a state in which the seedlings are seated in the cultivation hole 31 formed on the upper side of the first accommodating space S1, when the seedlings pass the growing season and the harvest season, the plants in the harvesting season are transferred to the upper side of the second receiving space S2. By moving to the cultivation hole 31, it is possible to supply a nutrient solution that does not contain potassium to the plants in the harvest season. At this time, the user rotates the seating plate 30 on the upper part of the lower frame 20 or moves the cultivation port 300 to the cultivation hole 31 formed on the upper side of the second receiving space S2, so that the harvester is in the state of the harvester. The plant may be moved to the upper side of the second accommodating space (S2).

For example, although not shown in the drawings, a protrusion capable of supporting the circumference of the seating plate 30 may be formed on the upper portion of the lower frame 20 . Therefore, the user can fix the seating plate 30 to the lower frame 20 by seating the seating plate 30 on the protrusion formed on the upper portion of the lower frame 20, and lifting the seating plate 30 as needed.

In this case, in a state in which the seating plate 30 is fastened to the lower frame 20 , the user may rotate the seating plate 30 by applying an external force.

The hydroponics apparatus 1 for growing low-potassium vegetables according to an embodiment of the present invention enables plants in the seedling and growing season to absorb the nutrient solution containing potassium in the first accommodation space S1, and is settled when the harvest season is reached. By rotating the plate 30 so that the plant in the harvest season can absorb the nutrient solution that does not contain potassium in the second receiving space S2, the amount of potassium is adjusted during the growing season of the plant, and the content of potassium absorbed in the crop can reduce Therefore, low-potassium vegetables can be grown.

The mounting plate 30 rotates according to the growth of the plant, so that the nutrient solution containing potassium and the nutrient solution not containing potassium can be absorbed, thereby cultivating low-potassium vegetables without going through a separate cultivation process.

The height adjustment unit 40 may adjust the separation distance between the upper frame 10 and the lower frame 20 . A cultivated plant is grown by the light irradiated from the LED lamp 11 , but the amount of heat and light generated from the LED lamp 11 must be appropriately adjusted according to the plant. To this end, the height adjustment unit 40 may adjust the distance between the upper frame 10 in which the LED lamp 11 is installed and the lower frame 20 in which the plant is seated. The height adjustment unit 40 may appropriately adjust the separation distance according to the type of plant or the growth of the cultivated plant.
