通过实验室鉴定、田间定点监测和大田调查,发现樱桃李属坏死环斑病毒病可通过嫁接、汁液摩擦等途径传播,病毒形态为球形,大小30 nm,无包膜;在西安地区年发生消长历经始发期、快速增长期、稳定期、衰退期4个阶段,一年具有两个发病高峰,相邻年份病害发生差异不大,但有一个缓慢增长的过程。川道、密度大、管理粗放有利于樱桃李属坏死环斑病毒病的发生,目前种植的大樱桃品种发病较重,当地小樱桃品种发病较轻。
Through laboratory identification, site-specific field monitoring and field surveys, it was found that the disease of cherry plum necrotic ringspot virus can be spread by grafting, juice friction and other means. The virus shape is spherical with the size of 30 nm and no capsule. In the year of Xi’an, After four stages of initial period, rapid growth period, stable period and decline period, there are two peak incidences in one year, and there is not much difference in disease occurrence in adjacent years, but there is a slow growth process. Chuan Road, density, extensive management is conducive to the occurrence of the cherry prunus necrosis ring spot virus disease, the current cultivation of cherry varieties heavier, the local incidence of small cherry varieties lighter.
