The invention discloses hydroponic nutrient solution of endive. The hydroponic nutrient solution of endive is prepared from macroelements, microelements and water, wherein the nutrient solution comprises the macroelements, such as carbon, hydrogen, oxygen, sulfur, nitrogen, phosphorus, potassium, calcium and magnesium, and the microelements, such as iron, boron, sodium, manganese, chlorine, zinc, copper and aluminum. The main ingredients of the hydroponic nutrient solution of endive include calcium nitrate terahydrate, potassium nitrate, monoammonium phosphate, magnesium sulfate heptahydrate, heptahydrate, ammonium molybdate, ferrous sulfate, zinc sulfate, sodium silicate, magnesium sulfate, cobalt chloride, ferrous sulphate heptahydrate, ethylene diamine tetraacetic acid, boric acid, manganese sulfate tetrahydrate, blue copperas, calcium nitrate, manganese sulfate, potassium iodide, sodium chloride and sodium molybdate. The hydroponic nutrient solution of endive is high in absorption and utilization rate; and growth of the endive is accelerated. Thus, waste caused by nutrition excess or shortage due to the fact that the endive slowly grows and the hydroponic nutrient solution of the endive has no pertinence for a long period of time is radically solved.
