摘　　要：通过田间采集枣树的树皮、树枝、枣股、枣刺、枣吊、落叶、落枣等越冬组织,在室内分离、镜检,确定了枣缩果病病原菌的越冬场所,细交链孢菌主要越冬场所为枣树冬季落叶、枣刺、枣吊和落枣,聚生小穴壳菌的主要越冬场所为一次枝树皮、二次枝树皮、主干树皮和枣股。the overwintering sites of Jujube fruit shrink disease pathogens were determined by microscopic examination of jujube barks, branch, mother spurs, jujube thorn, jujube deciduous supers, deciduous leaf and frult-dropping, Alternaria alternata passes winter mainly in deciduous leaf, jujube thorn, deciduous supers and fruit-dropping; Dothiorella gregaria mainly in first shoot bark, secondary shoot bark, trunk bark and mother spurs.
