Supply of fine
Paulownia variety
Seedlings are the material basis for afforestation. The quality of seedlings can directly affect the survival rate of afforestation, and it is also related to the growth and resistance to diseases and insect pests after afforestation. It not only affects the afforestation effect, but also directly affects the cost of afforestation.
No.3 Shan Tong and No.4 Shan Tong are the new generation of artificial-crossing type Paulownia which cultivated through 11 years of research. Our hybrids are non-invasive and cannot reproduce by seed flight. Reproduction is only possible a-sexually.This has been proven.
Shan Tong saplings are preserved perfectly during 56 days’ shipping
About No.3 Shan Tong and No.4 Shan Tong
No.3 Shan Tong and No.4 Shan Tong are the fastest growing tree in the world that forms timber. After its 8th year the formed highest quality timber is traded at the world’s markets more expensively than the wood of oak and beech.

Appropriate business solution
Paulownia wood is becoming an increasingly popular alternative to tropical woods. This is due to its low weight, low flammability and its very high bending strength and static stability.
In construction industry, wood processing, furniture, for veneers, for toys and packages. The wood is also used for music instruments, plane construction and shipbuilding.
Paulownia biomass as renewable energy
Paulownia biomass found application in several directions. The tree is a source of renewable energy, the wood is used as a renewable energy source for bioethanol, biogas, pellets, and timber chips.
