1988—1991年在河南省牟县枣区对枣疯病发病因子和防治技术进行了研究。结果表明,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(50m 以内)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(20年生以下)发病重,为42.9%;树龄大的(100年生)发病轻,为5.7%。品种之间抗病性和酶活性有显著差异,灰枣和扁核酸为感病品种,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
1988-1991 in jujube in Mou County of Henan Province jujube bovine disease and prevention and control of the disease were studied. The results showed that the jujube broom disease and the distance from the Berlin near, inter-crop species, age and size and variety. The incidence of the disease was about 52.2% -90.6% within the range of Platycladus orientalis (within 50m), and it was 14.4% with the intercropping of wheat and corn. The incidence of intercropping with peanut, sweet potato and sesame was 3.6%. Small age (20 years of age or less) severe onset, was 42.9%; older (100-year-old) incidence of light, 5.7%. There were significant differences in disease resistance and enzyme activity among the cultivars, with gray jujube and flat nucleic acid as susceptible cultivars with the incidence rates of 71.0% and 70.0%; Lingbao jujube and September juvenile were resistant to the disease with incidence rates of 0.6% and 4% ; Chicken heart jujube, jujube wide between middle. field
