The invention provides a trace element type amino acid-containing liquid water soluble fertilizer comprising the following components: cottonseed meal, corn cob, wheat bran, edible mushroom bran, silkworm chrysalis, cicada slough, waste animal fur, ferrous sulfate heptahydrate, copper sulfate pentahydrate, zinc sulfate heptahydrate, manganese sulfate monohydrate, sodium borate decahydrate, ammonium molybdate tetrahydrate, complex inoculants A and B, earthworm feces, citric acid, a pH regulator and water. Modern biotechnology is used to inoculate the compound inoculants A and B, and a two-stageaerobic fermentation production process is used to decompose plant proteins contained in agricultural waste and the edible mushroom bran and animal proteins contained in the waste animal fur into small molecule free amino acids and natural active substances and nutrients to provide comprehensive protection for the healthy growth of plants. Through chelation with trace element components, the trace element type amino acid-containing liquid water soluble fertilizer is prepared. The trace element type amino acid-containing liquid water soluble fertilizer makes full use of the agricultural waste,the edible mushroom bran and the waste animal fur to realize the reuse of resources, and is environmental-friendly and non-pollution.
