The invention discloses a DHAV (duck hepatitis A virus) typing detection method based on a fluorescent quantitative PCR (polymerase chain reaction) melting curve method. The DHAV typing detection method comprises steps as follows: virus RNA (ribonucleic acid) extraction and cDNA (complementary deoxyribonucleic acid) synthesis; preparation of positive standard forms; establishment of the DHAV typing detection method based on the fluorescent quantitative PCR melting curve method; method validation adopting a specificity test, a sensitivity test and a reproducibility test. According to the DHAV typing detection method, all that is required is to add a pair of primers, A and C gene types are detected by single tube, the method is simple and feasible, and time consumption is low; the whole amplification and detection process adopts closed tube operation, so that pollution of PCR amplification products is avoided, and false positive results are reduced; amplified fragments are short, higher annealing temperature is adopted, and amplification specificity is guaranteed. The fast DHAV typing detection method is established, great convenience is provided for correct diagnosis and control of the DHAV, and economic benefits of agricultural production are achieved.
