The effects of soil moisture,seed-covered sand thickness and temperature on seed germination and seedling growth of Salix gordejevii were studied under simulated field conditions.It was shown that(1) Salix gordejevii seeds were very sensitive to soil moisture and the optimal soil moisture for their germination ranged within 3%～20% and the soil moisture lower than 3% or higher than 20% inhibited their germination;(2) It was necessary to cover the seeds with sand and the optimal seed-covered sand thickness wa...
