1979年春,笔者引进了由浙江农业大学育成的杭青梨(自然杂交种),在我院梨品种园试栽.经五年的观察,认为它对于合肥地区的风土条件有较好的适应性,表现出早果、丰产、优质、抗病等特点,是一个在皖中较有发展前途的中熟梨品种.现就几年的观察研究,对杭青梨在合肥地区的生物学表现作一报告. 一、品种园立地条件合肥地处北纬31°51′,东经117°17′,气候、土壤等生境条件在皖中地区有相当的代表性.年平均气温15.2℃,1月份平均气温2.1℃,7月份平均气温28.5℃;年平均日照2,200小时;无霜期225天;年降水量970毫米,主要分布于5—9月份,尤
In the spring of 1979, the author introduced Hangqing pear (natural hybrid) bred by Zhejiang Agricultural University and tried planting pear varieties in our institute.After five years’ observation, it was considered that it had better adaptability to the terroir and soil conditions in Hefei, Showing early fruit, high yield, high quality, disease resistance and other characteristics, is a more promising development in Anhui Zhongshu pear varieties. Now on the few years of observation and research, Hang Qingli biological performance in Hefei to make a report First, the variety of garden site conditions Hefei is located at latitude 31 ° 51 ’north, longitude 117 ° 17’, climate, soil and other habitat conditions in the middle of Anhui are quite representative.An average annual temperature of 15.2 ℃, January average temperature of 2.1 ℃ , The average temperature in July 28.5 ℃; annual average 2,200 hours of sunshine; frost-free period of 225 days; annual precipitation of 970 mm, mainly in the May-September, especially in
