Persian Silk Tree Propagation methods

Throughout the Persian Silk Tree propagation, seeds are harvested between September and October, using plump, disease-free pods that are dried and purged in dry ventilation to prevent mold growth.

Raise seedlings in spring, soak seeds for 8-10h before sowing and then take them out for sowing. Furrow sowing was carried out, the furrow spacing was 60cm, and the soil was covered by 2-3cm. After sowing, the bed soil was kept moist and germinated for about 10d. The seeding capacity of 1h㎡ is about 150kg. The management of weeding, weeding and topdressing should be strengthened after seedling emergence. In the 2nd year, plant at 3-5m apart in spring or autumn. Weeding pine nests every spring and autumn for 2-3 years after transplanting to promote growth. 

Seed treatment

There are Only Persian silk trees seeds available in March and April of the following year. In order to ensure smooth germination and quick release of seeds in Persian silk trees, the seeds were immersed in 0.5% potassium permanganate in cold water for 2h 2 weeks in the first 2 weeks of distribution. After extraction, the seeds were washed in clear water and soaked in hot water around 80℃ for 30s (up to 1min, otherwise the germination rate would be affected) and seeded in 24h. Using this method to accelerate the germination rate can be up to 80%-90%, and the seedlings after robust growth are not easy to come on.
