摘　　要：【目的】弄清南疆枣园骏枣黑斑病和缩果病的空间分布规律,为掌握病害的流行规律和制定防治方法提供理论依据。【方法】采用随机取样的方法对南疆枣园骏枣黑斑病和缩果病的空间分布型与抽样技术进行了研究。【结果】骏枣黑斑病的空间分布型均为聚集分布,分布的基本成分为个体群;骏枣缩果病的空间分布型为随机分布,分布的基本成分为单个个体。根据平均拥挤度与平均密度的关系,建立了2种病害的回归方程,得到了2种病害在不同发病率及不同允许误差下的理论抽样数。【结论】为做好骏枣黑斑病和缩果病的预测预报工作和开展病害防治工作提供了理论依据。[ Objective] This project aims to clarify the spatial distribution of Jun -jujube black spot and fruit shrink disease in Southern Xinjiang in the hope of providing theoretical basis for mastering their epidemic regularity and formulating corresponding control measures. [ Method ] Spatial distribution and sampling technique of Jun -jujube black spot and fruit shrink disease were studied by using random sampling method. [ Result] The results showed that the distribution pattern of Jun-jujube was aggregative, and the distribution of basic component was individual group ; The distribution pattern of fruit shrink disease was random, and the distribution of basic component was a single individual. The optimum sampling number of the two diseases in permissible error and in different densities was determined according to the regression equation of average congestion. [ Conclusion ] The study provided a theoretical basis for forecasting and preventing Jun -jujube black spot and fruit shrink disease.
