Description

Plant cultivation using LED irradiation method

The present disclosure relates to a plant growing table using an LED irradiation method, and more particularly, to a plant growing table that increases light irradiation efficiency through a rotational LED irradiation method.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

The artificial light plant factory started in 1957 in Europe, where plants were cultivated using supplementary light, and then developed into a fully controlled plant factory using only artificial light in the United States in the 1960s. As they put salad vegetables on the market, they were able to secure the related technologies to date.

In a plant factory where plants are artificially grown as described above, an artificial cultivation bed is used instead of a large land such as a vegetable garden. The culture bed can be used for various purposes, but in the case of a culture bed using LED light, it can serve as a support for LED and nutrient solution injection and recovery as well as for the purpose of mounting plants on several layers. Among the purposes of these cultivation beds, the purpose of multi-level cultivation is the biggest. As many technological developments have been made in recent years, the concept of multi-layered cultivation goes beyond the simple concept of multi-layered cultivation. etc. have been developed.

Recently, the most widely used multi-level cultivation table is a vertical type cylindrical cultivation table (hereinafter referred to as a vertical cultivation table). In the case of the vertical cultivation table, cultivation is possible through sunlight, etc., and it has an excellent space utilization compared to a horizontal cultivation table and has a certain height, so there is an advantage that a person does not need to bend the waist to work.

In Patent Literature 1 (Registration Patent No. 10-1454198), (A) a bed frame 10 having a vertical cylindrical shape or a regular n-prismatic cylindrical shape; (B) two or more arc shapes (when the bed frame 10 is cylindrical shape) or n flat plate types (when the bed frame 10 is a regular n square cylinder shape) attached to the periphery of the bed frame 10, When attached to the bed frame (10), the vertical planting bed (20) in which a port containing ① a crop planted media or ② a crop planted media is mounted on the side facing outward when attached to the bed frame 10; (C) a vertical lighting unit 30 installed to be spaced apart from the bed frame 10 by a predetermined distance in an outer side direction of the bed frame 10; (D) a rotating part 40 for rotating the bed frame 10 with the vertical center of the bed frame 10 as a rotation axis; lighting applied to a plant factory including a planting bed set is disclosed.

The planting bed disclosed in Patent Document 1 is made in such a way that the bed frame 10 is irradiated with light from the vertical lighting unit 30 while rotating about the central vertical axis, but when the planting bed itself is rotated, the nutrient solution is sprayed. There is a problem that the nutrient solution may overflow due to rotation in the process of being transported to the lower part, and the plants are sprayed with the nutrient solution through the penetration part 22 from the nutrient solution injection pipe 51 located on the central axis of the bed frame 10. However, this spraying method has a disadvantage in that it is difficult for a large number of plants to receive and absorb a sufficient amount of nutrient solution evenly. In particular, in the case of a planting bed, it is essential to stably maintain the growth environment of plants through air circulation. In addition, providing a separate air circulation device for air circulation has a disadvantage in that it costs money.

In addition, in the case of plants, it is preferable to irradiate light by dividing the daytime and nighttime zones. However, if the plant has a continuously rotating structure, it receives light only during a specific time period, so there is a problem in that it can induce stress and slow growth.

In addition, in the case of a conventional plant growing table, a plurality of cultivation beds are arranged somewhat spaced apart, and thus the cultivation space is reduced, which has a disadvantage that cultivation efficiency may be somewhat decreased.
