Green flowers, how to breed paulownia

Dear friends, have you ever seen Datong Tong? the editor thinks that he is also a very good factory. Look, this is a picture of Datong. How about it? it's very beautiful. He also has a name called snow mud. I don't know how much he knows about him. Let's take a look at the editor.

Breeding methods of macrococci:

1. Planting and propagation of paulownia

Yellow sandalwood can sow and reproduce. It can be used in spring and autumn. Soak the seeds for 24 hours before sowing to promote germination. Culture soil mixed with humus, vegetable garden soil, and fine sand in a shallow basin or wooden box. After leveling the soil, spread the seeds evenly. After wetting at the bottom of the basin, the top is covered with glass. The seedlings emerged after about 10 days under the humidity of 18-20 ℃. After it appears, let it gradually see the sun. When the seedlings grow 3-4 true leaves, plant them in a small pot.

2. Reproductive reproduction of Dendrobium.

Echinococci can be propagated by ball division. Choose dormant 2-to 3-year-old bulbs. In autumn or from December to March of the following year, the soil was first immersed in the soil and kept at 22 ℃ for germination. When the bud grows to about 0.5 cm, dig out the ball and cut the ball into 2 to 4 pieces with a sharp knife. Each knife must have a bud and the cut is coated with ash to prevent decay. Each plant has a pot to form a new plant.

3. Insertion and propagation of giant rock branches

Branching and breeding methods are also common breeding methods of Pinus sylvestris var. mongolica. These branches often sprout on the stems of Pinus sylvestris var. mongolica. When cutting, cut 2-3 cm long and insert into fine sand or expanded perlite matrix. Pay attention to the shade to avoid sunlight. Keep the room temperature at 18-20 °C and the root for 15 days.

Leaf insertion and propagation of Populus euphratica

The growth of leaves of Pinus sylvestris var. mongolica is to select the leaves with strong growth and development, and the leaves are taken out from the petiole. Cut the leaf in half, insert the petiole obliquely into the wet sand substrate, cover and cover it with glass, and keep it at 25 ℃ at room temperature and high air humidity for 20 days after insertion at the base of the petiole to produce healing tissue, and grow into a small basin after moving into a small basin. In the same year, only small bulbs are formed, and new branches are issued from the bulbs after dormancy. After a period of cultivation, from June to July, the flowers bloomed.

5. Insert and propagate giant rock buds

Bud insertion is also a common breeding method of Pinus sylvestris var. mongolica. It usually takes place in the spring, and when the light bulb germinates from 4cm to 6cm, the extra seedlings germinated from the base are inserted into the sand bed and maintain a certain amount of humidity. After a period of cultivation, it blossomed from June to July.

Yellow sandalwood has strong growth ability and can use many breeding methods. It's also easy to feed. It also has several pots of paulownia flowers. It is believed to have a good effect.
