[Objective] To investigate the effects of different treatments on the rooting state of Acanthopanax giraldii Harms. softwood cuttings. [Method] Effects of medium, cutting period, cutting position and hormone concentration on the rooting state of Acanthopanax giraldii Harms. softwood cuttings were investigated through L9 (34) orthogonal test design. [Result] The rooting state of Acanthopanax giraldii Harms. softwood cuttings was obviously influenced by the medium, cutting period, cutting position and hormone concentration. From strong to less, the influencing order of factors to rooting rate was cutting period>medium>hormone concentration>cutting position; the influencing order of factors to rooting number was cutting position>hormone concentration>medium>cutting period and the influencing order of factors to rooting length was the cutting position>medium>hormone concentration>cutting period. The rooting rate, average root length and average root number were respectively 86.4%, 6.2 cm and 4.9 when middle or lower crown with part leaves as cuttings were treated by ABT1 in concentration of 100 mg/L for 2 h and then cut into medium of 100% vermiculite on June 25. [Conclusion] Using softwood of Acanthopanax giraldii Harms. as materials was feasible in the large-scale raising seedlings by cutting in greenhouse.
