The invention relates to a preparation method of a selenium enriched ecological amino acid nutrient solution, wherein the preparation method comprises the following production steps: S1, washing chicken feathers cleanly, and drying in the sun or baking; S2, diluting a low-heavy-metal concentrated sulfuric acid having the content of 93% by water and an acid into a dilute sulfuric acid solution; S3, loading the dilute sulfuric acid solution obtained in the step S2 into a cylinder body made of a stainless steel material, then adding the chicken feathers obtained in the step S1 into the cylinder body, and carrying out temperature control chelating; S4, decomposing all the chicken feathers into a paste liquid; S5, adjusting the pH value of the paste liquid obtained in the step S4 to neutral with calcareous and alkaline lime paste; S6, adding a CM strain and sugar into the paste liquid having the pH value adjusted to neutral; and S7, subpacking into plastic barrels with the amount of 25 kg per barrel, sealing barre
