Abstract: As is a deciduous tree, Styphnolobium japonicum is one of the best afforestation trees in Zhouqu County, which has high economic value and medicinal value, so it is widely planted in Zhouqu County. It is very important to do a good job of seedling rearing when afforestation is carried out. Whether the technology of seedling rearing is scientific or not directly affects the survival rate and afforestation effect, so it is of great significance to do a good job of seedling management. Taking the seedling cultivation of Styphnolobium japonicum in Zhouqu County as an example, this paper focused on the key points of seedling cultivation technology and afforestation technology.
