安徽不同区域雄性杨树优良品种(系)筛选研究

Study on Selection of Fine Male Poplar Cultivars in Different Regions of Anhui Province

为筛选出适合安徽江淮地区发展的雄性杨树优良品种(系),对全省杨树适生区域的多个试验林生长量进行多年定点连续调查。结果表明,淮北地区,长势好的有巨霸杨和湘林90杨;沿淮地区,江淮1号杨长势最好,与其他4个品种(系)达极显著差异,且比较耐瘠薄;江淮地区,长势突出的有2025杨和L-802杨,巨霸杨和江淮1号杨表现中上等;沿江地区,长势较好的有湘林90杨和江淮1号杨,经过5~10年的跟踪调查发现,这两个品种生长量大,抗逆性强,值得在沿江地区推广。本研究结果为今后雄性杨树优良品种(系)在全省推广示范奠定基础。

In order to select fine male poplar cultivars suitable in Jianghuai region of Anhui Province,consecutive surveys were made on the growth of several experimental poplar plantations in suitable areas of the province for years.The results showed that cultivars Juba and Xianglin 90 grew best in Huaibei Region.Cultivar Jianghuai No.1,tolerant in poor soil,grew best in areas along Huaihe River,with significant increment differences from 4 other cultivars(strains).Cultivars 2025 and L-802 grew best in Jianghuai Region while Juba and Jianghuai No.1 also grew quite well.Cultivars Xianglin 90 and Jianghuai No.1 grew well in areas along the Yangtze River and 5 to 10-year-long follow-up survey indicated that the two cultivars had high increment and good stress resistance,suitable for promotion in these areas.The study results could provide basis for promotion and demonstration of fine male poplar cultivars in the province in future.
