2. Soil texture: permeablility or breathability good loam and sand soil, avoid clay, harden, ventilation adverse soil.
3. PH of soil, 6-7.5 is the best, 5-8.9 is acceptable.
4. Good irrigation and drainage systerm will be better.
5. Elevation up to 2000m is acceptable
1. Fecund and wet. No ponding and water saturation
2. Annual rainfull 400mm-1200mm.
3. In seedling period, keep the soil with good moisture(20-40%), after grow up than 50cm drought resistant ability improve,then better and better.
4. Attention please: water enough, no ponding, keep soil breathing
1. Plant paulownia tree in sunny place and keep away from heavy wind.
2. Try to prohibit paulownia tree under other bigger trees
3. Density. For seedling using 0.8x1m or 1x1m distance, for forestation 4x4m or bigger distance.
Plant with crop distance more than 3x15m.
Annual temperature 12-20celsius degree grow better; -20-+45celsius degree is ok, vulnerable to frost damage if absolute temperature less than -25celsius degree.
At the first, for paulownia seed, paulownia root and paulownia stump, and other paulownia planting, give little fertilizer, and in the future: less quantity fertilizer and much more times.
1.For seedling, mainly by Paulownia seed and paulownia root, and the root is the better and common way.
2.Afforestation: paulownia root, paulownia stump and seedling of one or two years.
Difference of seed and root:
Paulownia seed price lower, but seed very small and light, high technical requirement, and it is hard to get better seedling in one year. Keep genn of original plant not so well, It's easy to have a separation phenomenon.
Plant by paulowna root(vegetativepropagation ), keep the nature of original species, simple technical, save work and time, get better paulownia tree.
Paulownia seeds: choose quality species tree,disinfection and drying,package and storge.
Paulownia root: take root out from soil of one year seedling-then cut them-clean soil- then disinfect with sevral drugs- washing-fumigation-trim-package-fresh keeping storehouse-arrange shipping.
Features of hybrid:
1. Hybrid by paulownia fortunei x tomentosa, parents are south and north species of Chinese.
2. The hybrid species inherited good gene of the both, has good environmental adaptability.
3. Fast growth, with medium crown, straight through trunk, small difference between top and end.
4. The first 1-3years fast growth of height, the first year 3-5m, the following more than 2-3m per year. From 3-4years height slowly and coarse grow faster, 4-9years is the fast period of thickness. 10years grow slowly and steadily. So the paulownia tree 7-10years mature, up to 0.8-1cbm per tree.
paulownia root size
special length and dia. is acceptable, but only for reserve order.
For example: 18-20cm length, 1.0-2.5cm dia., and so on.
