通过小X胡杨硬枝扦插试验,初步认为使用生根激素可以较明显提高插穗成活率,ABT1#生根粉效果最好,成活率较对照提高25.4%。激素在扦插当年对插穗生根起着关键作用,根系形成进入生长阶段后,继续生根不受激素影响。 Through the experiment of hardwood cutting of Populus euphratica, the survival rate of cuttings was obviously increased by using rooting hormone. The ABT1 # rooting powder had the best effect and the survival rate increased by 25.4% compared with the control. Hormone cuttings in the cuttings on the root plays a key role in root formation into the growth stage, continue to root without hormone effects.
