摘　　要：‘强德勒’红心柚引入本地后生长势强,丰产性能好。但目前在本地存在果实大小不一现象,2013年对自然生长的24株‘强德勒’红心柚1 492个果实进行果实大小重量分级分析,得出不同大小柚果数量和重量均呈正态分布,果实标准差为174.25,果实平均重为843.5 g,700 g以下果实占22.2%,占总个数的20.6%。因此建议：一,在6月中下旬疏果,疏除这些株均15~20个数量的小果虫果,以提高果实大小一致性;二,加强肥培管理,增施钾肥,减少裂果率;三,加强病虫害防治,可进行柚果套袋,提高柚果商品外观性能。以满足消费者需求促进销售,增加柚农收入。Chandler pomelo was introduced into Letianxi Town, Yiling District, Yichang City, Hubei Province, showing strong growth vigor and high yield.
