自1976年以来,北京郊区的团河农场、巨山农场、南大荒苗圃、芦沟桥公社果园大队等地果园的苹果上严重发生一种烂果病害。受害的品种以金冠为主,小国光、大国光次之,青香蕉、红星等品种也有发生。据统计:在上述果园因烂果病使苹果的产量损失每年达50—60％。现已查明,烂果病除在近郊区严重为害外,远郊区的苹果园发生也相当严重,因此已成为京郊地区苹果生产上主要的病害,其造成的损失远大于苹果炭疽病。此外,烂果病在天津等地也有发生。
Since 1976, a rotten fruit disease has apparently occurred on apples in orchards of Tuanhe Farm, Jushan Farm, Nanda Wilderness Nursery, and Lugouqiao Commune Orchard Brigade in the suburbs of Beijing. The victims of the Golden Delicious crown-based, small country light, the light of the big country, green banana, Red Star and other species have also occurred. According to statistics: in the above orchards due to rotten fruit diseases, the annual loss of apple production reached 50-60%. It has been ascertained that rotten fruit disease is severely damaged in the suburbs except for apples orchards in the outer suburbs and therefore has become a major disease in the production of apples in the suburbs of Beijing. The loss incurred is far greater than that of apple anthracnose. In addition, rotten fruit disease in Tianjin and other places have also occurred.
