Description

Mixed bed for plant cultivation with optional deep flow technique and aeroponics}

The present invention relates to a mixed bed for plant cultivation, and more specifically, to a mixed bed that can selectively carry out liquid culture and spray culture in one bed body.

Recently, the tendency to consume vegetables has changed to higher quality, simpler, and cleaner, and as infinite competition in the agricultural sector is expected due to the opening of agricultural product imports, some horticultural facilities are being converted to hydroponic cultivation facilities or newly built.

Despite the high initial facility investment costs, hydroponic cultivation can produce desirable agricultural products by improving continuous cropping obstacles and labor conditions, which have been problems in soil cultivation, artificially controlling the environmental conditions of above-ground and underground parts, mechanization, deviceization, and automation. It is expected to be the leading farming method of the next generation due to its various advantages, such as stabilization of productivity and increase in yield.

There are a variety of hydroponic cultivation methods, and from a grower's perspective, the selection of an effective hydroponic cultivation method for producing high-quality fruit is very important, and each cultivation method has its own pros and cons. Nutrient cultivation methods that are being put into practical use include Nutrient Film Technique (NFT), Aeroponics, Deep Flow Technique (DFT), and Rockwool culture.

Among these, spraying is a method of growing crops by spraying nutrient solution directly into the root zone with a spray nozzle to facilitate root respiration of crops. Since the root zone is exposed to the air, there is no need to worry about lack of oxygen, and it depends on the amount and moisture absorption characteristics of the crop. It can efficiently supply nutrients and moisture, and has the advantage of not requiring a specific medium.

Liquid culture is a method of cultivating crops by filling a cultivation tank of a certain size with culture medium by controlling the water level. Although the required capacity of culture medium is large, it is easy to form and control the nutrient solution, making cultivation stable and easy in conditions like Korea where weather fluctuations are severe and experts are not well trained.

Spray culture and liquid culture methods each require beds designed accordingly. In other words, the spray culture bed is designed so that the nutrient solution sprayed by the nozzle from the bottom can be supplied to the roots of the plant, and the soak culture bed is designed so that the roots of the plant can be submerged in the nutrient solution.

Accordingly, if a user wants to cultivate plants using two different methods, a spray system and a liquid system, the cost burden is high as two different beds must be provided, and each must be managed in a different way, which has the disadvantage of being cumbersome to manage.
