The invention belongs to the technical field of
plant cultivation, and concretely relates to a storing method of

ozone whose concentration is 10-20 ppm is introduced for 3-5 hours; (4) leaves with
insect pests and
disease spots as well as impurities are separated, qualified
Stevia rebaudiana leaves are put in storage; (5) Stevia rebaudiana leaves which pass the examination are put into the storage for storing, the temperature of the storage is controlled at 15-20 DEG C, the
humidity is controlled at 10-15%, woven bags are used for piling up and storing,
land occupation of each stack is 3-5 m<2>, and the distance between each stack is 30-50 cm. The storing method does not need any chemical medicines with convenient storing operation, low cost and high environmental friendliness.
