摘　　要：为探讨盐分对冷地型草坪草种子发芽的影响,研究NaCl、NaHCO3单盐对高羊毛、黑麦草、早熟禾3种草坪草种子发芽的影响。结果表明:低浓度NaHCO3、NaCl盐分对黑麦草、早熟禾种子发芽势和发芽率没有明显的抑制作用,NaCl大于0.09 mol/L或NaHCO3大于0.06 mol/L时,发芽势、发芽率降低明显;对高羊毛种子的发芽势和发芽率抑制作用强于黑麦草、早熟禾。NaHCO3对3个品种的发芽势、发芽率强于NaCl。To investigate the salt of the cool season turf grass seed germination,set NaCl,NaHCO3 single salt on turfgrass seed germination.The results showed that low concentrations of NaHCO3,NaCl salinity on ryegrass,kentucky bluegrass seed germination and germination rate did not significantly inhibit,NaCl than 0.09 mol/L or NaHCO3 than 0.06 mol/L,germination potential,germination rate decreased significantly;for festuca arundinacea seed germination and germination rate of inhibition was stronger than ryegrass and bluegrass.for NaHCO3 germination of three varieties,the germination rate was stronger than NaCl.The effect of NaHCO3 on the germination potential and the germination rates was stronger than NaCl.
