研究了不同扦插时间、不同枝条部位、不同激素及浓度处理对新疆杨嫩枝扦插生根的影响,结果表明,在6月20日扦插生根效果最好;不同枝条部位(带顶梢的插穗和不带顶梢的插穗)对扦插生根的影响不大;ABT1号生根粉生根粉200mg/L处理的效果最好,成活率可达95%,平均生根数为10.3条,平均根长为12.0cm,相同浓度的IBA和NAA处理效果次之;在低浓度的情况下(100～200mg/L),随着ABT1号生根粉处理浓度的加大,扦插的成活率提高,但处理浓度增加到400mg/L时,扦插生根效果开始下降,达到800mg/L时,则对扦插生根起到明显的抑制作用。
The effects of different cutting time, different branches and parts, different hormones and concentrations on the rooting of Softwood Cuttings of Xinjiang were studied. The results showed that rooting was the best on June 20, and the cuttings with different shoots Cutting with tops) had little effect on cutting rooting; ABT1 rooting powder rooting powder 200mg / L had the best effect, the survival rate was 95%, the average number of rooting was 10.3, the average root length was 12.0cm, The treatment with the same concentration of IBA and NAA took the second place. At the low concentration (100-200 mg / L), the survival rate of cuttage increased with the increase of ABT1 rooting powder treatment, but the treatment concentration increased to 400mg / L, cutting rooting began to decline, reaching 800mg / L, then cuttings rooting played a significant inhibitory effect.
