Description

Plant cultivation device

The present invention relates to a plant cultivation apparatus, and more particularly, to a plant cultivation apparatus capable of selectively providing suitable light required for growth depending on the cultivated plant and the growing season using LED.

In addition, the plant cultivation apparatus according to the present invention is provided with a water supply unit to provide the humidity necessary for growth according to the cultivated plant and the growing season, and to supply the oxygen to the cultivated plant at night .

Plant plants that have recently been gaining attention are plants that grow using pallets and lighting fixtures that contain culture fluid in a frame made of multi-layered shelves. Light and temperature are artificially controlled, It is possible to supply high quality vegetable with stable, consistent shape, taste and nutrient management. In addition, it is possible to eliminate the anxiety about the food, to be able to grow continuously, to adjust the length and the length of day and night, temperature and humidity, and the concentration of the culture medium and carbon dioxide. It is possible to cultivate full-scale plants even in the middle of the city by dramatically increasing yield compared with natural cultivation.

One of the main components of such a plant is an illumination system that provides the light necessary for plant growth and photosynthesis. Plants differ in their preferred wavelengths of light depending on their species and growth state. For example, the photosynthesis of chlorophyll absorbs the red or blue of the spectrum of light and reflects green, while the orange part reflects the germination of the plant, the growth of the root, the formation of the stem, the flowering time, It is involved in growth. Therefore, in plant factories, in order to utilize the characteristics of light of plants to the maximum, the contents of harvest are different depending on when and how much light of color light including many wavelengths required by plants is supplied.

The light sources such as blue light and red light of wavelengths required by the plant can be controlled by arbitrarily adjusting the emission wavelength and color depending on the type of impurities added to the semiconductor or coating, Emitting Diode) is used. Also, when a plant absorbs light, the light source is more effective as it is located closer to the plant, since the light is scattered and lost in the air when the light source is located far away from the plant.

Conventionally, a lighting apparatus is fixedly installed on a shelf structure, and its position is located at a high place for preventing interference due to the growth of plants. Therefore, from the initial stage of growing plants to the stage before harvesting, the lighting apparatus is located far away from the plant, and especially in the early stage of growth, the light absorption is very inefficient as the interval becomes excessively widened, which delays the plant growth rate and wastes illumination energy .

Further, in the case of a lighting apparatus using an LED as a light source, it is required that the irradiation angle is approximately 110 °, and 50% of the light amount is concentrated on the center side, On the other hand, the light absorption ability differs greatly depending on the growing season and the harvesting time. However, conventionally, there is a problem that the supply of light is constant, resulting in inefficiency and energy loss.

In addition, another of the major components of the plant is the humidity and oxygen concentration required for the plant's growth environment. The plants also differ in their preferred humidity and oxygen concentrations depending on their species and growth state. For example, in the case of tropical plants, the high temperature and humidity environment is the optimal growth environment. In addition, plants to be cultivated are not oxygenated by photosynthesis at night, but oxygen absorption by respiration occurs, resulting in lower oxygen concentration in the closed space. Therefore, in order to make full use of the characteristics of humidity and oxygen concentration of plants to be cultivated in plant factories, there is a difference in harvesting contents depending on when and how much moisture and oxygen concentration required by cultivated plants are supplied.
