Get better paulownia tree pay attention   as following

Land

1. Ground water level: more than 1.5m.

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

Water

1. Fecund and wet. No ponding and water saturation

2. Annual rainfull 400mm-1200mm.

3. In seedling period, keep the soil with good   moisture(around 30%), after grow up than 50cm drought resistant ability   improve, then better and better.

Sunshine

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.

Temperature

Annual temperature 12-20celsius degree grow better;   -20-45celsius degree is ok, vulnerable to frost damage if absolute   temperature less than -25celsius degree.

Fertilizer

At the first, for paulownia seed, paulownia root and   paulownia stump, and other paulownia planting, give little of not give   fertilizer, and in the future: less quantity fertilizer and much more time.

Features Instruction

Features

(Paulownia hybrid fortunei x tomentosa, 9501, Shantong, and so on)

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.
