The nutrient solution supply system of the present invention basically comprises a plurality of first raw liquid tanks for holding raw liquids containing elements required for crop growth, and a water liquid provided with at least one raw water tank for containing crops, and a control circuit. It is used to control the supply of the raw liquid in each of the first raw liquid tanks and the supply of the liquid water in the raw water tank. In response to crop demand, the raw liquid and water in a predetermined amount and proportion can be input into the corresponding cultivation tanks to effectively supplement the nutrients needed for crop growth, thereby reducing the labor cost, increasing crop yield and improving economic benefits.本創作之營養液供應系統，基本設有複數第一原液槽供盛裝溶有作物生長所需元素的原液，以及設有至少一原水槽供盛裝作物生長所需的水液，另設有一控制電路供控制各第一原液槽原液供給及原水槽之水液供給。可及時因應作物需求，將預先設定數量和比例的原液及水液輸入對應的栽培槽中，有效補充作物生長所需養分，達到降低人力成本，提高作物產量及提高經濟效益之目的。
