为给杨树产业提供大量良种壮苗．我院引进杨树杂交新品种进行多因子无性繁殖育苗试验。结果表明：新品种生根力强，扦插密度以6～8株／m2为宜，苗平均高1．80m．径1．70cm；插条长20cm左右成活率可达95％以上；以插条中部芽最饱满充实萌生苗粗壮，生长快；扦插后覆盖农膜芽萌发早．苗生长较整齐；扦插前用质量分数w为200×10-6可溶性糖处理插条，有助于根的萌发生长；平切直插有利于芽萌发和新梢生长。
To provide poplar seed industry a large number of strong seedlings. Our hospital introduced new hybrid poplar breeding multi-factor asexual breeding. The results showed that the rooting ability of the new varieties was good, the density of the cuttings was 6 ~ 8 plants / m2, the average height of the shoots was 1.80 m. Diameter of 1.70cm; cuttings length of 20cm or so survival rate of up to 95% or more; the middle part of the cuttings full of full enrichment sprout sturdy, fast growth; cuttings cover the plastic film bud germination early. Seedlings grew more neatly; Before cuttings, the cuttings were treated with 200 × 10-6 soluble sugar to improve the germination and growth of the roots. The cuttings were in favor of germination and shoot growth.
