The invention relates to a fresh-keeping processing method of Chunhua plum, which is implemented strictly according to the following steps of: processing before picking, picking, precooling, selecting, processing by antistaling agent solution, packing and refrigerating before picking, wherein the precooling is carried out by cool water, the temperature of the cooling water is controlled to be 3-4 DEG C, and the cooling time is 25-35 minutes, so that the temperature of the center of Chunhua plum body is reduced into 4-6 DEG C; and keeping the temperature of the refrigeration house or the refrigerating chamber to be kept at 3-5 DEG C when the plum is refrigerated, and controlling the relative humidity to be 85%-90%, wherein an air interchanger is arranged in the refrigeration house or the refrigerating chamber at the same time. The method provided by the invention has the beneficial effects that: the fruit cracking rate is reduced, the refrigerating temperature is greatly increased compared with the prior art, the power consumption cost of refrigeration is reduced, the comparison of each quality index of the fruit shows that the fruit is hard, and the total soluble solid (TSS) content is lower in the descent velocity compared with the control group under the temperature-reducing storage condition of the invention, and the fruit rotting rate and the fruit pulp browning index are slower in ascending velocity, so that the fresh-keeping processing method is suitable for large-scale popularization and application.
