摘要
‘北杨’是通过人工控制授粉选育而成,雄株,为美洲黑杨种内杂种,其母本为南抗杨,父本为‘D175’。9年生平均胸径21.3 cm,平均树高20.4 m,单株材积0.250 m^3,比对照‘中林2025杨’材积生长量提高49.9%。树冠长卵形,干形通直,冠幅中等,早期速生,抗光肩星天牛,耐瘠薄。
The ‘Beiyang＇,male clone and intraspecific hybrid of Populus deltoides hybrid,was selected from the progeny of Populus deltoides‘Nankang＇× P. deltoides ‘D175＇by the way of artificial control cross pollination. Average DBH,height and volume of nine-year-old ‘Beiyang＇were 21. 3 cm,20. 4 m and 0. 250 m3,which were 49. 9% greater than the control ‘2025＇. The elite variety has the fine characteristics such as straight trunk,middle crown,fast-growing,strong resistance to Anoplophora glaberipennis and soil barren tolerance.
