2、 How does Paulownia reproduce
1. Seeding and seedling raising: seeding and seedling raising are mostly carried out between February and March. Germination and disinfection should be carried out before sowing. The seeds can be soaked in warm water for about two days, and then sown when the seeds are white, so that the germination rate will be higher. Pay attention to covering the upper layer of soil with a thin layer of soil after sowing, and heat preservation and moisturizing treatment p>
2. Root burying and seedling raising: roots should be collected from deciduous trees to germination. Lateral roots of two or three centimeters thick should be selected from strong trees, and the length should be controlled at 15-20 centimeters. After cutting, they should be dried for two or three days, and then they can be buried directly or obliquely p>
3. Cutting seedling raising: in addition to the above two methods, cutting seedling raising can also be used. The specific method is to cut the annual robust branches as cuttings, and the length is controlled at about 20 cm. After treatment, it can be directly inserted into the matrix, and the survival rate is also relatively high p>
