摘要：
The present invention relates to a nutrient solution supply device for each element to supplement types of elements which are not absorbed but discharged by crops and a discharge amount for each element to supply the discharge amount for each element to the crops when supplying elements required to grow the crops. The nutrient solution supply device for each element comprises: a raw water inlet to induct water by a pump； a plurality of nutrient solution containers storing nutrient solutions including 13 elements required for crop growth； a plurality of solenoid valves connected to the nutrient solution containers to discharge the elements in the nutrient solution containers； an outlet to mix the nutrient solutions discharged by the solenoid valves and raw water inducted by a raw water supply unit (10) and then supply the mixture to a crop； a nutrient solution analysis unit installed on a discharge side of the crop to determine the type and amount of an element which is not absorbed and is discharged by the crop among the nutrient solutions supplied to the crop through the outlet (60)； and a control unit to adjust the nutrient solution amount by the solenoid valve and the nutrient solution analysis unit. The type and amount of an element which is not absorbed but discharged by a crop are analyzed to be supplemented to efficiently grow a functional crop. A solenoid valve which opens and closes multiple times in a short period is used to supply the amount of an element desired by a user. A venturi tube is used to efficiently supply a nutrient solution regardless of the pressure created in each line.본 발명은 작물 생육에 필요한 원소 공급시 작물이 흡수하지 못하고 배출되는 원소의 종류 및 원소별 배출량만큼을 작물에 보충하여 공급하기 위한 원소별 공급 양액기에 관한 것으로, 펌프에 의해 물을 흡입하는 원수 흡입구와, 작물 생육에 필요한 13개의 원소를 포함하는 양액이 각각 수납되어 있는 다수의 양액통과, 상기 각각의 양액통에 연결되어 양액통 내의 원소를 배출하기 위한 다수의 솔레노이드 밸브와 상기 각각의 솔레노이드 밸브를 통해 배출된 양액과 원수 공급부(10)를 통해 흡입한 원수를 혼합한 후 작물에 공급하는 토출구와, 상기 작물의 배출측의 위치에 설치되어 토출구(60)를 통해 작물에 공급하는 양액 중 작물이 흡수하지 못해 배출하는 원소 종류 및 배출되는 원소량을
