| 中文摘要: |
| 豆梨为我国南方常用的砧木资源之一,不仅具有良好的抗干旱、水涝和腐烂病的能力,还具有很高的药用价值,具有润肺止咳、清热解毒、健胃消食及涩肠止痢的功效。因此为了解中国南方豆梨资源的分布现状,并对其分布规律进行研究,采用资料调查、现场调查、访问调查、路线调查等方法,于2017年9月3日-16日, 9月23日-10月1日和10月30日-11月16日,前往浙江、湖南、湖北、广东、广西和江西6省的豆梨原生境采集豆梨资源78份,保存在中国农业科学院果树研究所下属国家梨种质资源圃中,并建立豆梨种质资源信息库,采用数量统计方法,研究不同经度、纬度、海拔、气象要素和立地条件等对豆梨分布的影响。结果表明,我国豆梨主要分布在湖南、湖北、江西、福建、广东、广西、浙江、云南、贵州、山西、安徽、河南、江苏、陕西、甘肃和山东等,共16个省,地理分布范围在北纬21.86°～36.18°和东经98.66°～120.64°之间,垂直分布范围在海拔8～2294m之间,不同的立地条件对豆梨的分布数量均有一定程度的影响。 |
| 英文摘要: |
| P. calleryana is one of the stock resources commonly used in southern China. It not only has good resistance to drought, waterlogging and canker disease, but also has high medicinal value. It has the functions of moistening lung and relieving cough, clearing heat and detoxification, strengthening stomach and eliminating food, and relieving dysentery with astringent intestines. Therefore, in order to understand the current situation of the distribution of P. calleryana resources in southern China, and to study its distribution regularity, the methods of data investigation, on-site investigation, interview investigation, route survey, etc., were adopted from September 3 to 16, 2017. September 23-October 1 and October 30-November 16, and visited Zhejiang, Hunan, Hubei, Guangdong, Guangxi and Jiangxi provinces to collect 78 P. calleryana. It was stored in the national pear germplasm resource nursery under the Institute of pomology of CAAS, and established P. calleryana germplasm resource information base. The quantitative statistical method was used to study the effects of different longitude, latitude and altitude,meteorological factors and site conditions on the distribution of P. calleryana. The results show that P. calleryana are mainly distributed in 16 provinces including Hunan , Hubei , Jiangxi , Fujian , Guangdong , Guangxi , Zhejiang , Yunnan , Guizhou , Shanxi , Anhui , Henan , Jiangsu , Shaanxi . Gansu and Shandong, with geographical distribution ranging from 21.86 °to 36.18 °N and longitude 98.66 °to 120.64 °E, and vertical distribution ranging from 8 to 2294m above sea level. Different site conditions affected the distribution of P. calleryana to a certain extent. |
