The invention discloses a hydrogen (pH) regulation type aqueous nutrient solution for tobacco seedling culture. The hydrogen regulation type aqueous nutrient solution is prepared from the following components in parts by weight: 18 to 28 parts of ferrous sulfate heptahydrate, 2 to 2.8 parts of copper sulfate pentahydrate, 7.5 to 8.5 parts of zinc sulfate heptahydrate, 3 to 5 parts of manganese sulfate monohydrate, 0.9 to 1.8 parts of sodium molybdate, 9 to 15 parts of boric acid, 20 to 30 parts of EDTA (Ethylene Diamine Tetraacetic Acid) disodium salt, 78 to 118 parts of water and 20 to 40 parts of a 2-hydroxyethylamine diluting solution. The invention further discloses a preparation method of the potential of hydrogen regulation type aqueous nutrient solution for the tobacco seedling culture. According to the hydrogen regulation type aqueous nutrient solution for the tobacco seedling culture, disclosed by the invention, a 2-hydroxyethylamine complexing agent is added to regulate the pH value so that ferrous
