摘要
为选择适合平原农区的优良品种,进行了毛白杨优良无性系选育试验。经过8a造林测定,筛选出3119、5057、0084、3882、5073、5048等6个优良无性系,均为雄株,其材积生长量分别超过对照(易县毛白杨雌株)的69.1%、53.3%、26.0%、15.4%、9.8%、4.4%、7.2%;
The experiments were conducted to select the superior clones of Populus tomentosa for the afforestation in plain agricultural area. By 8 years experiment of planting, six superior clones (3119, 5057, 0084, 3882, 5073, 5048) were selected out, all were staminiferous plants. The volume growth of the selected clones was higher than that of the control by 691%, 533%,260%,154%,98%,44% and 72%,and their morphological characteristics were also better.
