Description

Hydroponic growing device for trees and cultivation system including the same The present invention relates to a hydroponic plant cultivation device, and more specifically, to a hydroponic cultivation device and cultivation system for trees that can optimize the hydroponic cultivation space for tree cultivation and enable active control of the growth environment. In general, hydroponics refers to a method of growing crops by supplying a nutrient solution to the crops, in which nutrients required by the crops are dissolved in water and brought directly to the roots of the crops, or an inert medium that acts as a root support, such as rockwool, is soaked in a nutrient solution and brought to the roots of the crops. Since this type of hydroponic cultivation does not require soil, it is very inexpensive compared to conventional soil cultivation. Additionally, because cultivation takes place indoors, it is relatively less affected by weather, and because the environment is artificially created, it has the advantage of being free from various pests and diseases. Furthermore, the relatively pleasant working environment allows for greater efficiency with the same amount of labor compared to soil cultivation, and the continuous supply of appropriate nutrient solution tailored to the crop's physiology enables stable growth, thereby allowing for continuous harvesting throughout all four seasons. Meanwhile, global climate change is increasing the need for such hydroponics, as droughts, heavy rainfall, heavy snowfall, lack of sunlight, earthquakes, soil erosion, and pollution are occurring frequently and causing direct damage to agriculture worldwide. Since these climate changes degrade crop quality and reduce yields, global agflation is occurring as a result. Furthermore, hydroponic cultivation is on the rise in recent years due to the scarcity of space for growing plants caused by urban population density and a lack of cultivated soil. In particular, driven by the demand for high-efficiency cultivation of crops such as vegetables, there is a rapidly increasing need for technological improvements in hydroponics that can maximize space efficiency. Korean Utility Model Publication No. 20-2011-0009235 discloses a plant cultivation device of the prior art, and FIG. 1 is a front view showing the same. Looking specifically at the prior art described above, the container is configured to include a plurality of cultivation tanks (21) for planting plants inside, and a vertical fixing frame (25) in which support plates (26) on which the cultivation tanks (21) are placed and arranged form layers at predetermined intervals. The support plates (25) are installed so that the cultivation tanks (21) form three layers, and an artificial light source (30) is installed above the cultivation tanks (21) of each layer to irradiate light of different wavelengths depending on the type of plant planted in the cultivation tanks (21) of each layer. In addition, a nutrient solution supply unit is configured to supply nutrient solution for cultivation, and the nutrient solution supply unit is configured to include a nutrient solution tank, a nutrient solution supply pipe, a nutrient solution supply pump, a nutrient solution supply flow control valve, a nutrient solution drain pipe (55), a nutrient solution drain flow control valve (56), and a drainage tank (57). Although conventional hydroponic cultivation devices are configured in multiple tiers to maximize space utilization when cultivating vegetables, they are not suitable for application to trees with relatively thick and long trunks. This is because trees with above-ground stems generally anchor their roots in the soil to support their stems and leaves, making it difficult to simply apply conventional hydroponic structures; furthermore, maintenance and repair are challenging due to the large amount of space they occupy compared to vegetables. Furthermore, in the case of trees, applying hydroponics is difficult because they must not only possess an overall sturdy structure but also require continuous monitoring of the root condition during the growth process. Therefore, in order to cultivate trees hydroponically, a method suitable for their growth characteristics must be improved and applied.
