摘　　要：为寻求促进沙地植被恢复的新途径,提高防沙治沙造林效果,在库布齐沙漠沙柳(Salix psammophila C.Wang et.C.Y.Yang)造林前,使用平卧式和立式浸泡沙柳插穗7 d。结果表明,两种浸泡方式均能不同程度地提高沙柳成活率,平卧式和立式分别提高11个百分点和22个百分点;两种浸泡方式下沙柳成活率差异不显著(P=0.085 3),但枝条长度、枝条直径差异极显著(P<0.01),株高和冠幅差异显著(P<0.05);立式浸泡沙柳长势最好,其次为平卧式,对照长势最差。在库布齐沙漠风沙区造林时最好选择立式浸泡沙柳插穗以提高造林成效。In order to seeking new ways to promote afforestation and increase the effects of sand preventing and controlling,the experiment used horizontal and vertical ways to soak the Salix psammophila for 7 days before the afforestation.The results showed that two immersion ways could increase the survival rate in different degrees,which of the horizontal and vertical immersion ways increased by 11 and 22 percent point respectively.There was no significant difference between survival rates of the two immersion ways,however there was very significant difference in branch length and branch diameter,significant difference in plant height and crown.Hydrodynamic shock grew best in vertical immersion followed by horizontal immersion and grew worst in the control group.Therefore,vertical immersion is a better choice to improve afforestation effect in Kubuqi desert.
