The invention provides a processing technology of rosa roxburghii tratt fruit steaming green tea. The processing technology comprises the following steps of placing and spreading picked fresh rosa roxburghii tratt fruit young leaves on a winnowing fan placed in a processing room, wherein the room temperature is 23 DEG C, the spreading thickness does not exceed 2cm, and the spreading time is 4-8 hours, and when the dissipation rate of the moisture content of rosa roxburghii tratt fruit leaves is 2%, pouring the rosa roxburghii tratt fruit leaves in a steamer of which the steaming air temperature is 100 DEG C; performing fixation for 40 seconds, performing rolling until the breakage rate of cells reaches 45%, and determining the moderate rolling degree in a manner that when juice overflows and wet and sticking feelings are generated when hands tough the rolled rosa roxburghii tratt fruit leaves, the rosa roxburghii tratt fruit leaves are tightly grasped by hands, balls are formed, and when the hands are released, the balls are dispersed; placing the rolled rosa roxburghii tratt fruit leaves in a drying machine of which the temperature is 120 DEG C, performing drying for 30 minutes, adjusting the temperature to be 80 DEG C, and performing drying until drying is completed, wherein the mark of sufficient drying includes that when the dried rosa roxburghii tratt fruit leaves are grasped by hands, the rosa roxburghii tratt fruit leaves are crushed, stems of the dried rosa roxburghii tratt fruit leaves are easy to break, and the water content is 5-6%; and spreading the dried rosa roxburghii tratt fruit leaves for cooling to achieve room temperature, performing packaging, and performing storage.
