| 摘 要： | 土壤有效含水量处于7．2％至田间持水量之间时，杨树插穗成活率基本稳定在90％左右；如果土壤含水量超过田间持水量时，插穗的成活率则随着水分的增加而减少；如果土壤的有效含水量低于7．2％时，则插穗的成活率随着含水量的减少而相应的降低。

| Abstract: | Influences of soil moisture content on survival rate of the poplar cuttings are described:when the effective soil moisture content (ESMC) ranged from 7 2% to field moisture capacity (FMC), the survival rate of the poplar cuttings will stabilize at 90% or so. If ESMC higher than FMC, the survival rate of cuttings will reduce along with the increase of ESMC; if ESMC lower than 7 2%, the survival rate of cuttings will reduce along with the decrease of ESMC. |
