枣缩果病在南疆的分布及在新疆的适生区预测

Distribution of Jujube Fruit Shrink in Southern Xinjiang and the Potential Distribution Areas in the Whole Xinjiang

【目的】枣缩果病是枣树果实期的重要病害之一,明确枣缩果病分布现状及潜在分布区。【方法】采用实地调查及GARP生态位模型预测方法,对枣缩果病在新疆的地理分布和潜在分布区进行分析和预测。【结果】枣缩果病在新疆南疆四地州均有不同程度的发生。新疆地理范围内位于天山南麓与昆仑山北坡的南疆四地州及哈密地区绿州范围,以及伊犁部分地区均为枣缩果病适生区。【结论】新疆南疆四地州为枣缩果病的主要分布区和适生区;新疆枣树种植地区均存在枣缩果病的潜在威胁。

【Objection】Jujube friut shrink disease is one of the important diseases during the jujube fruit growth period. This project aims to make sure the actuality of its geographic distribution and the potential areas in Xinjiang.【Method】The geographic distribution and potential geographic distribution in Xinjiang were analyzed and predicted by using Desktop GARP and field investigation.【Result】The results indicated that the degrees of jujube friut shrink varied in the four prefectures in southern Xinjiang. The prediction results were the major adaptable areas in Xinjiang include： the place between the south slope of the Tianshan Mountains and Kunlun Mountains,the four prefectures in Southern Xinjiang and the oasis in Hami and finally some places in Yili Prefecture.【Conclusion】Four prefectures in Southern Xinjiang were the main distribution and the main suitable areas for jujube fruit shrink fruit disease,the potential threat to its planting area.
