The invention belongs to the technical field of storage and preservation of agricultural products and particularly relates to a crystal grape storage and preservation method, comprising the steps of (1) spraying 1500-2000 times of Trichoderma agent, namely natamycin composite bacteriostatic agent one day before bagging, and picking when reaching 70-80% of maturity; (2) removing bags after picking, picking out rotten fruits, waxing pedicles, subpackaging PE preservation bag lined transfer boxes, healing at normal temperature in the shade for 12-24 h, placing the transfer boxes in a cold store, and sterilizing the cold store and fruits with ozone or ultraviolet; (3) precooling in the cold store at 1.0+/-0.5 DEG C for 24 h, adding a sterilizing agent and an ethylene blocking agent, tying the bags and storing. Severe biological disease damage, short shelf life, proneness to browning and other problems in existing crystal grape are solved, the shelf life of crystal grape is extended from 7 days to 60 days which leaves 6 days for the sales time, and the crystal grape storage and preservation method is simple to perform, high in efficiency and good in safety.
