Paulownia is native to China and has been cultivated here for more than 2,000 years. Shaanxi province — and the Weinan region in particular — sits in the tree's historic heartland, where generations of farmers and decades of formal research have turned paulownia growing into a precise, repeatable technology.
A natural laboratory
Shaanxi's climate spans warm-temperate to semi-arid conditions, with cold winters (down to -20 °C) and hot summers (up to 42 °C). Paulownia varieties and techniques proven here transfer reliably to a wide band of climates worldwide — from Central Asia to Southern Europe to the Middle East — which is exactly where global demand for fast-growing timber is rising fastest.
Research that reaches the field
Our center undertakes cultivation research and fine variety promotion for key scientific accomplishments at state, province and city levels, and has designed and guided paulownia afforestation in many areas of China and abroad. The result is a body of practice that covers the whole life of a plantation:
- Before planting: soil determination and comprehensive land evaluation; variety selection for the local climate;
- Establishment: planting density, hole preparation, watering schedules that maximize first-year survival;
- Growing phase: guided fertilization, irrigation, intercropping design, pest and disease prevention;
- Timber quality: pruning and tending for straight, knot-free boles; thinning schedules;
- Harvest and regrowth: coppice management so one planting yields multiple harvests over decades.
Bred here: Shan Tong No. 3 & No. 4
Eleven years of artificial-crossing research produced our flagship hybrids — among the fastest-growing timber-forming trees in the world, non-invasive, non-GMO, and strongly resistant to disease and pests. Variety and technique are two halves of the same system: the genetics set the ceiling, the cultivation technology determines how close you get to it.
What we offer partners abroad
Today we export cultivation technology, not just plants: consultation, plantation design, soil and site evaluation, fertilization and irrigation programs, pest control and team training — remotely or on site. If you are considering paulownia, the fastest way to de-risk the project is to start a conversation with people who have grown it at scale for decades.
