毛白杨生长快、材质好,深受群众欢迎。目前,虽然它的无性繁殖方法很多,但由于种条不易生根,育苗较困难,繁殖系数很低。为此,我们于1978～1981年进行了单芽育苗技术的研究,在1978～1980年小面积试验中,秧苗最高成活可达89％;在1981年较大面积(2.8亩)中间试验中秧苗成活率为58.0％,繁殖系数29.7～45.6,为埋条育苗的15～23倍,四年中共培育单芽秧苗11.719株。 Populus fast growth, good material, welcomed by the masses. At present, although it has many vegetative propagation methods, it is difficult to nurture seedlings and has a low propagation coefficient due to the difficulty of rooting. To this end, we conducted a single-bud seedling technology from 1978 to 1981, with a maximum survival of up to 89% of the seedlings in the small-area test from 1978 to 1980. In 1981, a larger area (2.8 acres) The survival rate was 58.0%, the coefficient of multiplication was 29.7 ~ 45.6, which was 15- to 23-fold for buried barn seedlings, and 11.719 single seedling seedlings were cultivated in four years.
