Description

Hydroponics cultivation system capable of selectively supplying two types of nutrion liquid

The present invention relates to a hydroponic cultivation device, and more particularly, to a hydroponic cultivation device capable of selectively supplying two different types of nutrient solutions.

With the recent rise in interest in health, there is a trend to avoid agricultural products using pesticides harmful to the human body in food, and to prefer eco-friendly organic products without pesticides even though they are relatively expensive. In addition, as distrust of imported agricultural products and controversy over the harmfulness of genetically modified agricultural products (GMO) increase, ordinary households are also interested in growing organic products such as vegetables for their own consumption on rooftops, verandas, or indoors. households are increasing.

In response to this, hydroponic cultivation (or nutrient solution cultivation), which uses a simple structured cultivation device and a nutrient solution supply device to grow plants by supplying nutrient solution containing nutrients to plants without using culture soil or using only a small amount if used. ; hydrophonics) method has been developed. Compared to soil cultivation, such hydroponic cultivation not only enables continuous cultivation in the same place for a long period of time, but also yields a constant harvest without a difference in weather conditions. In addition, the environment can be made under the same conditions and the cultivation environment is clean, so fresh and clean crops can be mass-produced throughout the year. In addition, automation of cultivation management is possible, so labor can be reduced, and quality and hygiene are better than crops produced by soil cultivation.

1 is a view showing the configuration of a conventional hydroponic cultivation apparatus 10. As shown, the conventional hydroponic cultivation apparatus 10 includes a plurality of beds 11 having a port insertion hole 12 into which a port A in which plants are planted is inserted, a nutrient solution tank 13 in which nutrient solution is stored, It includes a nutrient solution supply pipe 15 for supplying the nutrient solution in the nutrient solution tank 13 to the plurality of beds 11.

The nutrient solution tank 13 is provided with a nutrient solution supply pump 13a to supply the nutrient solution to the nutrient solution supply pipe 15.

Since the conventional hydroponic cultivation apparatus 10 has a structure in which one type of nutrient solution is circulated through the nutrient solution supply pipe 15, the same nutrient solution is supplied to all types of plants planted on the bed 11. Accordingly, the conventional hydroponic cultivation apparatus 10 has a limitation in that the nutrient solution cannot be changed when the nutrient solution needs to be changed according to the type of plant.

That is, when a different type of nutrient solution needs to be supplied, the port in which the plant is planted has to be separated and moved to a hydroponic cultivation device in which a different type of nutrient solution is supplied.
