山楂为我国特有果树。果实营养丰富,用途广泛,但长期以来管理粗放,病虫成灾。经在我省调查,发现新梢花期枯萎病,是影响产量的主要病害之一,一般病梢率在15—30%,重者竟达48%,皆发生在结果树上。大量果枝的枯萎直接影响着产量,经查阅资料尚无记栽描叙,可能为我国新发现病害之一? Hawthorn is our unique fruit tree. The fruit is rich in nutrition and has a wide range of uses, but extensive management and pest and disease disaster have long been carried out. After investigation in our province, it was found that the fresh shoot flowering blight was one of the main diseases affecting the yield. The general disease shoot rate was 15-30% and the severe case was 48%, all of which occurred on the result tree. A large number of fruiting branches wilted directly affect the yield, there is no documented description of the search information may be one of the newly discovered diseases in China?
