Abstract: In order to clarify the advantages and disadvantages of traditional storage methods of Weining potato, the occurrence of main diseases and quality changes of Weining potato seed potatoes after storage were studied. The results showed that the traditional storage method had high energy saving and space utilization rate, but the incidence of main diseases increased significantly, and the increase of soil-borne diseases was the most obvious. The best storage method for potato seed storage was constant temperature storage in intelligent cold storage. Traditional storage storage room bulk storage could be used for seed potato storage under the condition of sufficient storage space. It was not suitable for seed potato storage in situ soil culture storage.
