摘　　要：对我国14个主要产区9个不同种类柑橘果实采后病害发生动态进行调查和病害鉴定,结果发现:采后病害种类主要为青绿霉病、酸腐病、蒂腐病、炭疽病和黑腐病,尤其以青绿霉病为主;不同种类柑橘的主要病害类型不同,青绿霉病在宽皮类柑橘中发生频率较高,而酸腐病为脐橙的主要病害;贮藏2个月的病害发生率与采前1周雨日密切相关,因此认为晴天采收有利于降低采后病害的发生。同时,认为可以根据不同种类的柑橘品种依据其主要病害类型采取更有针对性的采后处理措施。Postharvest diseases of citrus caused by pathogenic fungi make great losses to citrus industry.Dynamics of postharvest diseases of nine different kinds of citrus fruit from 14 areas during storage were investigated and the pathogens were identified.The results showed that green/blue mold,sour rot,stem-end rot,anthracnose and black rot were observed.The green/blue mold was the main disease.Green/blue mold is dominant on mandarins and sour rot is common on sweet oranges.The incidence of postharvest disease after 60 days’storage is closely correlated with the rainy day during the one week before harvest.Therefore,harvesting on sunny days is beneficial to reduce the incidence of postharvest diseases.It is indicated that more targeted post-harvest treatments can be taken according to different types of citrus varieties based on their main disease types.
