Provided is an apparatus for automatically controlling and supplying a nutrient solution, provided to dilute different types of nutrient solutions at a uniform concentration with a simple structure. The apparatus for automatically controlling and supplying a nutrient solution comprises: a water storage tank which stores water and has a supply pipe connected to one side thereof; a plurality of nutrient solution storage units in which a nutrient solution is stored; a pump which sucks and discharges water through the supply pipe; and a narrow passage which is connected to the supply pipe, and in which the nutrient solution is sucked by a pressure difference of the water flowing between an inflow unit and an outflow unit and then mixed. In addition, the apparatus according to the present invention further includes a mixed orifice pipe connected with each end portion of a plurality of connection pipes which are individually connected to each of the nutrient solution storage units along the circumferential direction of the narrow passage. |
