The invention relates to a novel orthobunyavirus fluorescence quantitative RT-PCR (Reverse Transcriptase-Polymerase Chain Reaction) detection kit and a novel orthobunyavirus detection method, and aims to provide the kit which is convenient to use and accurate in detection and the detection method which is high in accuracy and high in detection efficiency. The technical scheme is that: the novel orthobunyavirus fluorescence quantitative RT-PCR detection kit comprises a specific primer, a fluorescent probe, a PCR buffer solution, dideoxyribonucleotide triphosphate and a mixed preparation, wherein an upstream primer has a sequence of FP:5'-TGGCCCTGGCTCTATAAACAT-3'; a downstream primer has a sequence of RP:5'-AATGGCAGCCCAAATGAATC-3'; the specific probe has a sequence of P:5'-FAM-TCCAATGAYGCCAAGAAGTGGAA-BHQ1-3'; FAM is a fluorescent reporter group; and BHQ1 is a fluorescent quenching group.
