摘　　要：对李属坏死环斑病毒病的发生危害特点进行了广泛调查,总结得出该病毒病发生与品种、树龄及地形等环境因子的关系．不同品种间樱桃李属坏死环斑病毒病发病程度存在差异,国外引进品种重于本地品种;不同树龄的樱桃感病率不一,一般来说,树龄越大,发病越重;地形对发病程度也有影响,川道区重于山岭区．选取两个不同的地点,对李属坏死环斑病毒病的药剂防治进行了试验,筛选出防效较好药剂．提出樱桃李属坏死环斑病毒病的综合治理措施．We explored the characrteristics of Prunus nenecrotic ring-spot virus （PNRSV） development, The relation between disease occurrence and variety as well as environments were analyzed, Results as follows： the damaged of PNRSV varies in different chery variety, exotic cherry varieties are most seriously damaged. As to different tree age, the damages go up with the tree ages. The trees on plain were damaged more several than that on mountainous region. Several effective medicaments were sieved, a series of comprehensive technical measure was studies.
