Propagation and operation of Bauhinia chinensis

Bauhinia is also known as full-striped red, Sufang flowers, the most special is that Bauhinia blossoms first and then grow leaves, flowering flowers, very beautiful, so the ornamental value is also very high. Now some flower friends will make bauhinia into bonsai, which can also change the home environment at home.

Bauhinia chinensis

1. Sowing: the seeds were collected from October to November, and the net seeds were obtained by sun rubbing and threshing, which were suitable for dry storage, and the germination rate was maintained at 85%. Winter sowing or spring sowing is OK. Soak the seeds with 30 ℃ of warm water for one day and night before sowing, remove the dry strip and sow it with a distance of 15 cm and a depth of 3 cm. Cover soil 1 cm, sow about 3 kg per mu. It can sprout and unearthed at the end of April. When the seedlings have 2 true leaves, interseedling and seedling replenishment should be carried out.

2. Ramet: it is usually carried out before bud germination in spring. Because the phloem of its root is well developed, it is not easy to be truncated, so it can be separated by sharp knife or scissors, and a small amount of strip propagation can also be carried out in spring.

3. Cuttage: it is carried out in the summer growing season, cutting off the twigs of the same year as cuttings, which can also survive in sandy soil, but it is not commonly used in production.

4. Striping: it can be carried out in the whole growing season, but it can not take root until the second year, so the method is more tedious, the propagation coefficient is not high, and the plant growth is weak after seedling, so it is rarely used in production.

Introduction to the propagation methods of Bauhinia

Bauhinia flower

Bauhinia is popular in China and popular in all countries. It is a kind of sunny and cold-resistant ornamental plant. It is named after the scientific name of Bauhinia in many areas. Its plant is very long, the flowers are purplish red, a string of rows on the tree pole is very beautiful, it is the best ornamental plant in spring, but also an excellent variety to beautify the home, let's learn about the breeding method of bauhinia.

I. growth habits of Bauhinia chinensis

Warm zone tree species, more hardy. Like light, slightly resistant to overcast. Like fertile, well-drained soil, not resistant to moisture. Strong sprouting ability and resistance to pruning

II. Propagation methods of Bauhinia chinensis

1. Sowing seeds

Collect mature pods from September to October, take out the seeds, bury them in dry sand and place them in a cool place to survive the winter. Sow seeds from late March to early April the following year, and treat the seeds before sowing. Only in this way can the seedlings be strong and strong. Soak the seeds in 60 ℃ warm water and continue soaking for 3 to 5 days after cooling. It is necessary to change cold water once a day. After absorbing and expanding, the seeds are placed in 15 ℃ environment to accelerate germination, drench with warm water once or twice a day, and sow in the seedling bed after whitening. Seedlings can be completed in 2 weeks, and seedlings can be properly separated after emergence. 4 true leaves can be transplanted in the nursery, and the loose and fertile loam is better in the border land. In order to facilitate management, planting practice wide and narrow row, wide row 60 cm, narrow row 40 cm, plant spacing 30 cm to 40 cm. It is not cold-resistant in seedling stage, and plastic arch shed should be used to protect it in winter.

two。 Ramet

The root of Bauhinia is easy to produce tillers. It is easy to survive by replanting the lateral root connected with the mother plant with a sharp knife before sprouting in October or spring. The ramets should be protected in winter in autumn and planted in March in spring. It can usually blossom in the second year.

3. Pressing strip

The growing season can be carried out, and it is better from March to April in spring. Air pressing method can choose 1-2-year-old branches, cut with a sharp knife and peel the bark around 1.5 cm, expose the xylem, and apply the rooting powder solution (diluted according to the instructions) to about 3 cm above the cut site. After drying, cover the cut with a barrel-shaped plastic bag, fill it with loose garden soil, and tie it tightly at both ends after watering. Check after one month, if the soil is too dry, it can replenish water and moisturize, cut off and plant again after taking root.

The shrub tree can choose the outer soft, 1-to 2-year-old branches to burn the base, spread the rooting powder, bury it in the soil after sharp bending, press the brick and stone to fix it, and the top tip can be supported by a stick. It is generally divided and replanted in March of the following year. Some branches do not take root in that year, but can continue to be buried and can take root the next year. If you continue to bury the pressure, it can take root in the next year.

4. Cuttage

In the summer growing season, cut off the current year's twigs to do cuttings, inserted in the sand can also survive, but not commonly used in production.

5. Grafting

Ordinary bauhinia and giant bauhinia can be used as rootstocks, but the cold resistance of giant bauhinia is not strong, so it is not suitable for use in the north. The buds or branches of excellent varieties such as Canadian red-leaf bauhinia were used as scions, which required pure varieties and exuberant growth, and the plants with no or less diseases and insect pests were selected to enrich the branches on the sunny side, and the leaves were cut off after scion collection and grafted in time. The method of branch grafting can be used from April to May and from August to September, and bud grafting can be used in July. If the weather is dry, permeable water should be irrigated 1 to 2 days before grafting to improve the survival rate of grafting.

There are many breeding methods of Bauhinia, and it is also very easy to operate. it can be used with a little understanding, and it is one of the best flower plants for practice. Novice flower friends can try it boldly.

The Culture method of Bauhinia how to raise Bauhinia

Bauhinia is a plant of the family Rosaceae. It has large flowers and a good smell. There are many opportunities for Bauhinia perianth to be planted and cultivated in the park. Bauhinia red and white are very beautiful, and Bauhinia also has edible value. Now let's share the culture methods of Bauhinia.

Culture method of Bauhinia chinensis

I. the culture method of bauhinia-- temperature

Bauhinia is a Chinese variety, and it is now planted all over the world. Bauhinia has strong vitality and strong resistance to cold and drought, so it is not difficult to be heavy. During the growth of the bauhinia, the temperature can be controlled at about 25 degrees, and the high temperature in summer is not good for the bauhinia.

2. the culture method of bauhinia-- humidity

Bauhinia pays more attention to air circulation in the process of growth, and the air quality is also critical. Harmful substances such as fluoride in the air can cause bauhinia poisoning without better performance. The soil of bauhinia had better be rich in organic matter and slightly acidic.

III. Breeding method of Bauhinia chinensis

The most common propagation of bauhinia is the use of cutting methods, the biggest advantage of cutting is that it can be operated in any season, but it is recommended to control it in autumn and winter. The regulation of temperature and moisture should be strengthened after summer cutting, otherwise the bauhinia will not be able to take root and sprout well.

Fourth, the culture method of bauhinia flower-pruning

The bauhinia needs pruning. It is recommended that the bauhinia should be trimmed in December to cut off some withered and yellow leaves to facilitate the subsequent growth of the branches.
