Abstract: 【OBJECTIVE】 Ficus wightiana, a Ficus species of northernmost distribution, is a choiceness species in greening of urban streets and building of coastal protection forest, so has great extension value. 【METHOD】To lay the foundation of expand its cultivation scale, this paper aims at study the cutting techniques of Ficus wightiana. In the controlled condition of different environmental factors, branches of different lignification extent were selected, and were dealt with dipping in different concentration ABT rooting powder or NAA solutions for different times, then cut in substrates of different component and ratio. 【RESULTS】 (1) one-year-old semi-lignification twig, V(peat): V(perlite):V(sand) 40:30:15 were the best techniques. By applying techniques above, the surviving rate could reach 82.6%, and the time of rooting was only 20 days. (2) ABT rooting powder and NAA can both promote rooting and surviving. The optimal hormone treatments were ABT(300mg/L) for 45 minutes and NAA (600mg/L) for 10 minutes. 【CONCLUSION】The former hormone treatment could brought the surviving rate at 80.3%, and the time of rooting was only 22 days. The latter hormone treatment could brought the surviving rate at 83.0%, and the time of rooting was only 21 days. The conclusion was educed that the rooting and surviving rate for cutting propagation of Ficus wightiana could reach above 82% under controlled environment of temperature, relative humidity and moisture of substrate, selecting appropriate stem cuttings and substrate, treated appropriate hormone treatment.
