Introducing Jacaranda, what is Jacaranda?

There should be no legend.

Jacaranda, the crown is tall, the plant height can reach more than 15 meters, the leaves are alternate, the two pinnate compound leaves, the small leaves are small, pinnae, and the growth is compact, quite beautiful. The apical or axillary panicles are extremely numerous, dark blue or blue-purple, and covered with branches, which is extremely spectacular. Each flower can be up to 20 cm long, with dozens of flowers, and the flower is bell-shaped.

Capsule. Propagation: Jacaranda is propagated by seeds, cuttings, tissue culture and other methods. The capsule ripens in November, is exposed to the sun or stacked in a windless place after harvesting, and stored until March of the following year after drying, and sown when the temperature is around 20, but the seed germination rate is only about 5%.

Jacaranda cuttings propagation can be carried out in spring and autumn, and medium-ripe branches are selected as cuttings, and the root rate is high. The tissue culture of jacaranda is also relatively easy, and some scientific research units in China have used the stem tops and stem segments of seedlings to propagate a large number of test-tube seedlings for exocolones.

Cultivation: (1) Temperature and light: Jacaranda is native to tropical America, prefers warm, humid and sunny environments, and is not tolerant to frost and snow.

The suitable growth temperature is 22 to 30, if the winter temperature is lower than 15, the growth will be stagnant, if it is lower than 3 to 5, there is cooling damage, and the summer temperature is 32 higher than the temperature, and the growth is also inhibited. Likes light and can tolerate semi-shade. (2) soil and fertilization; Like fertile and moist sandy loam soil or loam soil, planting should be applied enough base fertilizer, after surviving in spring and autumn each need to top dressing 1 time, pruning and pruning in early spring every year, aging plants need to be re-pruned.

When potting, it can be dried or grafted and dwarfed, and watering and nitrogen fertilizer can be controlled. (3) pest control: jacaranda has fewer diseases, the main insect pests are longhorn beetle, such as the base of the trunk is found to have reddish-brown feces, you can use a knife to pick open the bark cortex to catch the larvae; It is also possible to apply a mixture of 10 parts of quicklime, sulfur 1 valent and salt at the base of the trunk below 80 cm before the adult worm occurs to prevent the adult from laying eggs.

Scientific name: Family: Jacaranda deciduous tree of the family Asteraceae.

Origin and distribution: Origin: Brazil, Bolivia, Argentina. It is cultivated in Guangzhou, Hainan, Guangxi, Fujian and southern Yunnan in China.

Main use: Ornamental trees for a beautiful garden. In the south, it is used as a garden or street tree, and in the north, it is mostly cultivated in greenhouses, and its leaves are shaped like ferns, which is very beautiful; Potted plants have both flowers and leaves. The wood material is light and soft, the texture is straight, easy to process, and can be used to make furniture.

Jacaranda. It is a kind of arbor plant, it can grow to a height of about 10-15 meters, the flowering time is around May, it can grow small purple flowers, set off with green leaves is very good-looking, jacaranda is native to Brazil and other countries, and was later introduced into our country, and it grows in all parts of the north and south of our country. Jacaranda is a high-quality flowering and foliage tree, which can be planted in parks and gardens to beautify the environment, and can also be planted as a street tree.

Jacaranda likes milder sunlight, in spring and autumn it can be directly placed in the sun to grow, in summer to carry out some protective work, we generally use shade nets to water this net and other measures. Jacaranda needs a lot of nutrients in the growth and development, so fertilization work can not be less, jacaranda is a fertilizer-loving plant, we generally have to follow the principle of thin fertilizer diligently, fertilize about 2-3 times a month, before fertilizing to water the jacaranda first, so as to ensure that the jacaranda will not be too dense fertilizer and burn seedlings.

Usually in an unsuitable environment, such as rosemary in the summer heat, will accelerate the lignification.

Flowering: From November to the end of March, the apical meristem of jacaranda is still in the vegetative phase. The apical meristem expands in early April and forms a flower primordium from mid-April to early May.

The apical and lateral flower bud primordium differentiated rapidly, and flower spikes could be observed by mid-May in Douwufeng. No flower bud differentiation was observed under 25 consecutive conditions. Flower bud differentiation requires at least 1 month of low temperature (15) conditions, while normal flowering requires more than 3 months of low temperature conditions.

When it starts to grow in spring, it is appropriate to get more sunlight to facilitate flowering in autumn.

Low temperature: 1-2-year-old young trees are quite sensitive to frost, generally 0 frozen shoots, -3 o'clock all above-ground tissues frozen to death. The 3-year-old has a DBH of about 6 cm, and its cold tolerance is also greatly improved, and it can tolerate low temperatures for a short time.8 But the growth is poor, -3 frozen shoots.

You're not the only one who thinks she's beautiful, many people think she's beautiful. Especially Gao Hong and Stephen Chow's "Journey to the West", we think it is really beautiful, she looks like she has the characteristics of self-esteem

jacaranda！She was afraid that I didn't understand, so she repeated it slowly, jacaranda! The pronunciation of the ruler bridge in English is also beautiful.

Many people say that the flower language of jacaranda is waiting for love in despair, so it always has a bit of melancholy and desolation. However, in the eyes of Australians, there is pure spirit.

Jacaranda, also known as bauhinia, is a common tree in the Indochina Peninsula, its flower color is gorgeous, the color is different, there are dark blue, light blue, purple red, etc., the flowering period is about a month. Jacaranda is one of the symbols of the Indochina Peninsula region and is widely distributed in southern China.

Jacaranda varieties are very diverse, and they can grow and reproduce in different cultivation environments. They also reproduce in a variety of ways, including cuttings, grafting, and seedling raising. In the cultivation process, it is necessary to pay attention to environmental factors such as soil fertility, light, and temperature to ensure its normal growth.

Jacaranda is a very beautiful tree species that can not only beautify the natural environment in cities, but also be used for landscaping and lawn planting. Its standing on the ground not only provides people with a beautiful green environment, but also provides fresh air. At the same time, its flowers are colorful and long, and it often becomes a good place for people to enjoy flowers.

In short, the jacaranda is a very graceful tree, loved for its tall and straight posture and colorful flowers. Whether in the city or in the countryside, whether it is used for gardening or landscaping, jacaranda will become one of the representatives of the beautiful nature of the Indochina Peninsula.

Cyana and jacaranda refer to the same plant, which is an excellent tree species that integrates foliage and flowers. The maintenance of jacaranda should ensure that the soil is loose and fertile, with good drainage, its cold tolerance is poor, and it will be frozen if it is less than 5, so it is necessary to take insulation measures in advance. It should also be given sufficient scattered light, which is more conducive to the growth and flowering of the plant.

Jacaranda and jacaranda refer to the same kind of plant, it is a deciduous tree of the family Asteraceae and Jacaranda, it is an excellent tree species integrating leaf viewing and flower viewing, and has a large area of planting in southern China.

1. Soil requirements

Jacaranda grows best in loose and fertile, well-drained sandy loam soil, and the cultivation of jacaranda potted plants can be mixed with humus soil, river sandy soil, and pastoral soil, and a small amount of organic fertilizer is added when the soil is mixed to ensure the fertility of the soil.

2. The temperature is suitable

Jacaranda prefers a warm environment, its most suitable temperature for growth is around 25, its cold tolerance is poor, below 15 will stop growing, below 5 plants will be frozen. Therefore, the maintenance of jacaranda must be well kept warm in advance to ensure that the plant successfully overwinters.

3. Sufficient light

There is no difference between the jacaranda and the jacaranda, both are the same creature.

The jacaranda and jacaranda are actually the same, its scientific name is jacaranda, and the name of the jacaranda flower is not accurate. It itself is a deciduous tree of the genus Jacaranda in the Asteraceae family, which can grow up to 15 meters tall, the leaves are opposite, the flowers are blue, the inflorescence is about 30 cm long, and the calyx is cylindrical. It blooms in May-June, and after flowering, it bears woody capsules.

Habits

Jacaranda flowers grow best in loose, fertile and well-drained sandy loam soil, and can use mixed soil such as humus soil, river sand soil, and pastoral soil to ensure fertility. Jacaranda prefers warm climatic conditions, the optimum growing temperature is 25, but the cold tolerance is poor, and the growth will stop below 15, and the growth below 5 will freeze to death.

Therefore, it is necessary to pay attention to protection in winter to ensure the safety of jacarandas. Jacaranda likes light conditions and has a certain resistance to negativity, so it is best to place it in a place with enough scattered light to make it more flowers and more ornamental.
