The present invention relates to a nutrient solution supply system, comprising: a raw water tank being supplied with raw water; a first pipe connected to the raw water tank and having a first filter for filtering foreign matters and having a first pump for controlling a liquid flow; a nutrient tank being supplied with a nutrient solution; a second pipe having a second filter connected to the nutrient tank and for filtering foreign matters, and having a second value for controlling a liquid flow; a nutrient solution controlling unit connected to the second pipe and for controlling a flow of a nutrient solution; a mixing tank into which raw water and a nutrient solution stored in the raw water tank and the nutrient solution tank, respectively, flow to be mixed and stirred and thereby, nutrients are stored therein; a third pipe for spraying nutrients stored in the mixing tank to crops; and a circulation value connected to the third pipe and for controlling a portion of nutrients flowing into the third pipe to flow back to the mixing tank. The present invention allows raw water and a nutrient solution, which flow to the mixing tank through the nutrient solution controlling unit and the circulation pipe, to be mixed and stirred while having a predetermined pressure such that raw water and a nutrient solution get mixed consistently, thereby a stirring time can be reduced, a pressure of a liquid flowing to the first, the second and the third pipe connected to the mixing tank can be controlled uniformly, thereby, a concentration of nutrients stirred in the mixing tank can be easily controlled, and accordingly there is an advantage in that a user is able to supply nutrients to crops easily. |
