贵州省纬度低,海拔高,具有明显的亚热带高原气候特征。省内梨树栽培历史悠久,资源丰富,分布广泛。调查结果表明,全省80多个县市均有梨树栽培。在长期的生产实践中,形成了许多地方优良品种。由于贵州地貌复杂,气候差异大,梨树分布具有明确的水平地带性和垂直地带性。从全省来看,梨树主要集中在海拔600~1800米,年平均气温14~17℃的地区,并以省的西北部地方品种多,向东部逐渐减少。据不完全调查,仅威宁县就有60多个地方品种。经过初步调查整理,地方梨品种有140多个。在黔西北和黔西南有集中成片的野生种资源分布。现仅将11个优良地方品种介绍如下。
Guizhou Province has low latitude and high altitude, with obvious subtropical plateau climate characteristics. Pear cultivation in the province has a long history, rich resources, widely distributed. Survey results show that the province more than 80 counties have pear cultivation. In the long-term production practice, many local varieties have been formed. Due to the complex landforms in Guizhou and the large differences in climate, the distribution of pear trees has clear horizontal and vertical zonality. From the perspective of the whole province, pear trees are mainly concentrated in areas of 600-1800 meters above sea level and annual average temperature of 14-17 degrees Celsius, with a large number of local varieties in the northwest of the province and gradually decreasing toward the east. According to incomplete survey, there are more than 60 local varieties in Weining County alone. After preliminary investigation and sorting, more than 140 varieties of local pear. There is concentrated distribution of wild species resources in northwest Guizhou and southwest Guizhou. Now only 11 good local varieties introduced below.
