摘要
江淮地区中林系列杨树适生品种选择试验结果表明,不同杨树品种间胸径与高生长差异显著;中林系列杨各品种间,除中林46杨外,树高生长差异不显著;107杨后期生长快,其胸径与材积生长量分别为其他品种的142.37%、220.00%;江淮地区造林应首选南林351杨等南方杨树品种,107杨可适当引种,用于多品系配置。
Selection experiment on suitable varieties of Zhonglin series poplars in Jianghuai areas was carried out. The results showed that the differences of diameter at breast height and height increment among varieties were significant; the differences of height increment among Zhonglin series poplars were not significant, except Zhonglin No.46 poplar; the No.107 poplar grew rapidly in later period, the diameter at breast height and volume increment were respectively equal to 142.37% and 220.00% of other varieties; the south area poplars such as Nanlin No.351 poplar were the first choices for forestation in Jianghuai ares, and the No.107 poplar might be properly introduced for varieties configuration.
