Description

Nutrient solution treating apparatus for sterilizing and activating nutrient solution and culture medium cultivation system using the same The present invention relates to a cultivation medium technology using a nutrient solution, and more specifically, to a technology for sterilizing and activating a nutrient solution used in cultivation medium by treating it. Generally, substrate cultivation is an agricultural method in which terrestrial plants are grown without soil using water supplemented with a nutrient solution (nutrient medium). The nutrient solution is supplied either by applying it directly to the plant roots or by soaking an inert support that acts as a root support. Compared to absorbing nutrients through soil, receiving nutrients via a nutrient solution allows plants to absorb them much more efficiently, thereby promoting growth. By utilizing this substrate cultivation method, the plant's growth environment can be precisely controlled, enabling not only increased yields but also the adjustment of the harvest time. Furthermore, it makes crop production possible even in areas with deteriorated soil quality or regions where growing crops is difficult.
