The sowing method of cutting propagation of paulownia flower

With regard to the reproduction of plants, there are a variety of ways and methods, and there are many reproduction methods available for the same kind of plant, and at the same time, the same way of reproduction can be used in different parts of the plant, which sounds a little incredible. Don't worry. After watching the cutting methods of big paulownia flowers, you can break your traditional view of cutting.

How to cuttage propagation of paulownia flower

1. The branches of paulownia.

Choose a container with holes at the bottom to help drain water and keep the soil loose and transparent. When mixing soil, choose fine sand or perlite, the lower part is filled with peat soil, and the upper part is packed with perlite. Select the shoots from which the tubers grow 4 leaves, roast the scissors with fire, and cut the shoots from the roots. Dig a small hole in the soil, put the branches and buds in, and then cover the soil, be careful not to insert bluntly to avoid damaging the wound. After planting, pay attention to shade, avoid direct sunlight, maintain the ambient temperature at 18 ℃-20 ℃, and sprout in about 15 days.

2. Leaf cuttings of paulownia.

When the flower lags behind, choose the leaves on the luxuriant and resistant plants, together with the petiole, and pick them from the base. Cut the leaf in half and insert the petiole obliquely into the matrix of perlite and vermiculite, leaving 2/3 of the leaf surface on the surface. Cover it with glass, place it in a cool place, keep the ambient temperature at 25 ℃ and high humidity, and the seedlings will grow in about 20 days and then move into the flowerpot.

3. Bud insertion of paulownia.

It is usually carried out when the new buds germinated in spring grow to 4mi 6cm. Break off the extra new buds from the base, insert them into the sand bed, and maintain a certain humidity and temperature. After a period of cultivation, they will blossom in June and July of the following year.

Sowing method of paulownia flower

1. Seed selection of paulownia.

If you want paulownia to blossom more, we need those imported hybrid varieties with luxuriant flowering, short and strong plant type, strong resistance and easy maintenance, and single-petal varieties have more specific petal varieties.

2. Acquisition of seeds of paulownia.

It is difficult for paulownia to self-pollinate. In order to obtain excellent seeds, artificial pollination should be carried out. In the flowering stage, the pollen of stamens was collected and painted on the stigma of pistil with a brush. The seeds will mature about 35 days after pollination, and the seeds will be removed and dried and stored.

3. The sowing process of paulownia.

Before sowing, soak the seed in water for 24 hours to promote its germination ahead of time. The best combination of basin soil is rotten leaf soil, vegetable garden soil and fine sand. After leveling the soil, spread seeds evenly, soak the pot in shallow water and remove it, cover it with glass and place it in a semi-shaded place to maintain a humidity of 18-20 ℃. Seedlings can emerge in about 10 days, and then let the tree gradually see the sun, but to avoid direct sunlight, often spray, maintain humidity, apply thin cake fertilizer and water every 10 days or so, generally blossom about 6 months after sowing.

How to change the basin of paulownia

First, the time to change the basin

It is usually necessary to change the basin during the winter dormant period.

Second, the steps of changing the basin

1. The soil it uses is a mixture of nutritious soil and peat soil. You'd better add a little more base fertilizer. The composition of the soil can also be matched by itself, but a key point to grasp is to ensure that the soil is breathable, and it should be watered properly, but not too much.

2. The sphere is required to be dormant. After completing the first two steps, we will dig it out of the previous basin and put it into the new one. If the sphere has too many messy roots, you can do some pruning, be careful not to overtrim.

3. Find a flowerpot of the right size. The size of the flowerpot is based on the ball. The pot still needs to be a little bigger than the ball. It is good if the radius is two or three centimeters larger. If the basin is too large and the soil is too much, the soil is not easy to dry out after watering, and if the ball is wet for a long time, it will do great harm, such as the root is easy to rot. The bottom of the flowerpot is required to have holes for water loss, so that it can be breathable, and it is best to cover it with materials with better permeability and leakage, such as palm leaves, and so on. 4. don't bury all the bulbs in the soil, the upper part of it should be exposed. Its buds grow from the upper part of the sphere, and the buds rot easily in the soil. Up to this step, the step of changing the basin is perfect, and then we should pay attention to its usual breeding.

III. Maintenance after changing basins

After changing the basin, you should pay attention to concealment, put it in a warm environment, water it regularly, and it is best to sprinkle it with a spray can every day, so as to promote growth. As long as it is properly maintained, it can grow very well.

The flowering period of paulownia

The flowers of paulownia are terminal or axillary on the branches, and the Corolla is bell-shaped; the colors of the flowers are pink, red, purple-blue, white, complex and so on, and the flowers are large. One tree can blossom as many as dozens of flowers. The flowering period of paulownia is between April and November, and the flowering period is longer.

Paulownia is a very beautiful plant, of course, this beauty is mainly based on the flowering of paulownia, so if you want to appreciate it, it is very important to determine its florescence. Once the flowers are in full bloom, it can really be regarded as a grand occasion.
