To provide the basis for cultivar screening and technical application of cherry in Weining County, the growth potential and number of flower-buds were investigated and researched by the correlation analysis method. The results showed that Sangtina grew well and Sunburst was relatively poor in the aspect of growth characters in the Niupeng model orchard of Weining County, which was similar to the growth in the Heishi model orchard of Weining County. The growth characters of flower buds presented a similar case as well in the two model orchards, that was, much more on Brooks, and less on Sangtina and Black Pearl. The correlation between growth characteristics and the number of flower buds was different in the two model orchards. Conclusion; Heishi was the optimal planting region for the different cultivars of cherry, and the growth status of Shamidou was good in two model orchards.%为筛选出威宁地区适栽大樱桃的品种及为其栽培措施的制定提供参考,采用相关性分析方法,对大樱桃不同品种在威宁的生长势和花芽数进行调查研究.结果表明:生长特性,在威宁县牛棚示范园中,桑提娜的长势较好,艳阳较差,在威宁县黑石示范园的表现与牛棚示范园相似；2个示范园的花芽形成能力相似,均为布鲁克斯的较多,桑提娜、黑珍珠的较少；示范园中不同品种的生长特性与花芽数量呈现出不同的相关性.结论:威宁黑石是大樱桃的适种区域,而砂密豆在2个示范区生长状况都较好.
