Raw water may be used as tap water, preferably, it is preferable to remove chlorine by leaving it for 2-3 days before the preparation of the culture solution.

The culture medium used for hydroponic cultivation of the seaweed of the present invention preferably at the pH of 7.0 ~ 8.0, the temperature is maintained at 18 ~ 22 ℃. In addition, when the organic fertilizer is added to the culture solution, the conductivity Ec is preferably 15 ± 3.0. Seaweed is a crop that is very sensitive to pH and temperature, it is difficult to grow crops through hydroponics if the conditions are out of the above conditions.

The cultivation of the seaweed is preferably cultivated on a multistage shelf in an enclosed environment as in the apparatus shown in FIG. 1, wherein the temperature of the cultivation chamber is maintained at 20-25 ° C., and the humidity is maintained at 60-70%. In addition, the concentration of CO _{2 in} the cultivation room is preferably 300 to 500 ppm, and the concentration of O ₂ is maintained at 18 to 25%. These conditions are very important for the production of seaweed, and if the temperature, humidity, carbon dioxide and oxygen concentration in the growing room are below or above the above range, the production of the seaweed cannot be maximized. In addition, it is preferable to cultivate on a multi-stage shelf as in the embodiment of the present invention so that there is no difference in temperature for each shelf during the cultivation process. In this case, there is a problem in that the production environment of the crop is different for each shelf, the difference in yield.

The planting apparatus of seaweed according to the present invention may use the closed hydroponic apparatus 100 shown in FIG.

The planting device of the seaweed is a raw material supply unit consisting of a seawater tank 10, a raw water tank 11, an organic fertilizer tank 13, an acid tank 14, and a supply pump 10a for injecting each of the raw materials into a mixing tank, respectively. 11a, 12a, 13a, valves 10b, 11b, 12b, 13b for controlling the opening and closing of the culture medium, and the respective raw materials supplied through the supply pumps 10a, 11a, 12a, 13a by mixing Mixed tank 20 made of a culture solution, a pump 20a for supplying the culture solution from the mixing tank to the closed culture space, a valve 20b and a closed cultivation for opening and closing the flow rate and control of the culture solution supplied from the pump 20a It includes a CO ₂ pump 40 for controlling the concentration of carbon dioxide in the space, the hermetic cultivation space is a multi-stage shelf (30) and the cultivation shelf (30) equipped with a multi-stage cultivation shelf 31 for hydroponic cultivation of grasswort ( 31) The artificial light (32) installed on the top to supply light Each is provided.

As described above, the process of supplying the culture solution prepared in the mixing tank 20 to each shelf 31 of each multi-stage shelf 30 may be automatically controlled by a timer.

In addition, the artificial light 32 is good to be able to adjust its height manually or automatically in accordance with the culture step of the seaweed. This is not only important for inducing germination after sowing, but also plays an important role in shortening the growing period or increasing the content of functional substances in the growing process.

Hereinafter, the contents of the present invention will be described in detail by dividing the steps by the cultivation process of seaweed.

Sowing and germination stages

In the sowing and germination stages of the weeds, the culture solution is fed with 4 to 6 times seawater, preferably 5 times dilution. In this step, when the artificial light 32 is a fluorescent lamp, the height is adjusted to 3 to 5 cm from the crop, and the LED (LED) is preferably adjusted to 15 to 20 cm from the crop. If the height of the artificial light is less than 3cm (15cm in the case of LED), the germination may be delayed by 1 ~ 2 days or the yield of seeds may be reduced by about 5 ~ 10% due to the heating of artificial light. (20cm in the case of LED), the speed of germination slows down by one to three days, which is undesirable. In particular, when the seeding / germination stages are 2-4 days of cancer germination conditions and 4-10 days of photo germination conditions, germination rates of 80% or more are more than twice higher than those of 40% germination.

[Raising and recording stage]

The seedling and greening step is carried out 5-10 days after sowing, and in this process, the culture solution for hydroponic cultivation of seaweed is supplied in 4 to 6 times, preferably 5 times dilution. In this step, when the artificial light 32 is a fluorescent lamp, the height is adjusted to 5 to 10 cm from the crop, and the LED (LED) is preferably adjusted to 20 to 30 cm from the crop. If the height of the artificial light is less than 5 cm (20 cm in the case of LED), there is a problem that the germination slows down or the number of seeds decreases due to the heating of the artificial light, and when it exceeds 10 cm (30 cm in the case of LED), 1 Growth condition suitable for tea plantation, that is, resistance to high salinity is reduced than seedling / greening stage, and it is reduced by 10 ~ 20% than the number of planted plants at the distance of 10 ~ 15cm after the first planting. It is not desirable to have. Through such a step, the seaweed can withstand higher salinity and is provided with a prerequisite that it can contain more various functional materials containing seawater during the cultivation process.

[Full stage]

The formal step according to an embodiment of the present invention includes a first formal followed by a second formal process.

Preferably, the first set meal is carried out 16 to 20 days after sowing and the second set meal is carried out 30 to 50 days after sowing, and in this process, as a culture medium for hydroponic cultivation of seaweed 2 to 3 times, Preferably it is supplied as a 2-fold dilution liquid. In the formal stage, when the artificial light 32 is a fluorescent lamp, the height is adjusted to 15 to 20 cm from the crop, and the LED (LED) is preferably adjusted to 25 to 35 cm from the crop. By this formalization process, the growth period of seaweed can be shortened more, and the content of functional substance can be further increased.

[Intensive Steps for Partial and Functional Substances]

This step is a pre-harvest harvesting step of fertilizing the growing seaweeds to promote the growth of the area where it can be sampled or to contain more functional substances. In other words, it is possible to increase the value of crops by controlling the growth rate of stem and leaves and the content of functional substances according to the site of tasting. This step is carried out 60-65 days after sowing. In this process, seawater is supplied as a stock solution (100%) as a culture medium for hydroponic cultivation of seaweed. In this step, when the artificial light 32 is a fluorescent lamp, the height is adjusted to 25 to 30 cm from the crop, and the LED (LED) is preferably adjusted to 35 to 50 cm from the crop.

When cultivating the seaweed by the above process, there is no need for a separate process of removing salt, and it is possible to grow a large amount of seaweed containing various minerals and useful components contained in seawater in an environmentally friendly mass, and in particular, functional materials such as various minerals. It can maximize the content of can provide a high value-added and safe edible crops.
