Deciduous trees or shrubs, canopy spherical, hi light, cold, drought-resistant barren and light saline soil. In view of this, according to the biological characteristics and growth habit of Jinyeyu, taking the demand of urban landscape application type as the goal, this paper combined the breeding technology and innovative design concept of Jinyeyu with the modern seedling breeding technology to realize the scale production.
