The current problem is seedling shortage. The test area does not have the conditions of large-scale propagation of Populus euphratica seedlings by using irrigated fields. In the dry land, Populus euphratica is propagated by the general cuttage seedling method. The seedling growth rate is slow and the survival rate is low (about 60%). In addition, early spring catastrophic climate, planting seedlings to create a survival rate of farmland shelter only
