摘 要:枣疯病病情与距侧柏林远近、间作物种类、树龄大小及品种等有关。距侧柏林近发病重,发病率达52.2%~90.6%;与小麦、玉米间作发病较重,为14.4%;与花生、红薯、芝麻间作发病轻,为3.6%;树龄小的(20a生以内)发病重,为42.9%,树龄大的(100a生)发病轻,为5.7%;品种之间抗病性和酶活性有显著差异,灰枣、扁核酸为感病品种,发病率为71.0%和70.0%,灵宝枣和九月青抗病,发病率为0.6%和4%,鸡心枣、广洋枣介于中间。田间防治试验证明,用“去丛灵”钻孔施药带和曲颈瓶施药法疗效显著,治愈率12.5%~25%,总有效率为50%~56.3%。采取综合措施和伐除重病株,可预防该病害的扩展蔓延。The result of studying on the diseasing factors demonstrated that the severity of the disease was relative to the distance to oriental arborvitae forest, the species of intercropping fillers and the age and variety of jujube. The disease was serious with the near to the forest, with wheat and corn for intercrops(opposite to with peanut, sweet potato and sesame)and with the young jujube. The resistance and enzyme activation were significantly different among jujube varieties. The controlling experiment in the field showed that drilling holes in the stem and the crank neck bottle with 'antiwitches' broom' were effective to the disease. The disease could also be prevented by adopting integrated controlling management and cutting down the severely diseased trees.
