The invention relates to the technical field of tea processing, and provides a processing method of semi-fermented steamed green tea. The processing method comprises the steps of tender picking, withering, stirring, standing, steaming, heat dissipation, dehumidification, rolling, primary drying, secondary rolling, secondary drying and aroma enhancement; the produced tea not only has the advantagesof steaming, but also achieves the effect of converting aroma generated in stir-frying through subsequent aroma enhancement, so that the processed tea is not only rich in inclusion but also rich in taste, and the steaming technology is adopted to solve the problems that the fixation temperature is not easy to regulate and control, the fixation degree is not easy to master, the yield is low due toexcessive water loss of fresh leaves in the fixation process and the like in the existing stir-frying technology.
