two。 Propagation methods of African Chrysanthemum

1. Sowing method

Usually, African chrysanthemum can bear 20 or 30 seeds per flower, which can be sown in spring or autumn. Spring sowing usually takes place in March and May, while autumn sowing takes place in September and October of the year. Sowing should be carried out immediately after the seed is mature, thinking that the life of the seed is relatively short and cannot be stored for a long time. And it is best to choose artificial pollination at flowering stage, because the germination rate of seeds is only about 50%, covered with paper after sowing to prevent direct sunlight, and the temperature is 20 ℃ 25 min, germinating in about two weeks. Sixty or seventy days after sowing, flowerpots were transplanted or planted in the open field when the seedlings had three or four true leaves. Two or three months after cultivation, you can see the propagation methods of flowering African chrysanthemum. This method is relatively common and easy to operate.

two。 Test tube seedling raising method

If test-tube breeding can be carried out in places with favorable conditions, it will be more beneficial to accelerate the breeding and promotion of improved varieties. At present, this method is not very common in China, and it is widely used in the Netherlands, the United States, Japan, West Germany and other countries. This method can better breed more gerbera.

3. Split-plant method

Ramet propagation is mostly carried out in March and April. First dig out the mother plant, cut into several sub-plants, sub-plant must have buds and roots, and should not be too small, pot should not be too deep, it is best to dig a group of two plants to plant, which is conducive to increase the number of flowers.

I believe that after reading the introduction of the editor, you will be able to raise a healthier and more beautiful gerbera!

How do African chrysanthemums reproduce? Propagation methods of African Chrysanthemum

African chrysanthemum flowers are large, elegant, elegant, elegant and elegant, giving people a sense of warmth, peace and enthusiasm, and strong decoration, resistance to long-distance transportation, long-time water culture, so it is an ideal cut flower material. So, do you know how to reproduce African chrysanthemum? The breeding method of African chrysanthemum, let's take it together:

The propagation methods of African chrysanthemum are commonly used in sowing, plant division, cutting and tissue culture.

1. Sowing and reproduction: African chrysanthemum is a cross-pollinated plant, self-sterile, its seed offspring are bound to mutate. Sowing and reproduction are often used in breeding. Spring sowing from March to May and autumn sowing from September to October, it is best to sow seeds immediately after maturity. The optimum temperature for germination was 18-20 ℃, and germinated 7-10 days after sowing. The seed germination rate was about 50%, and the seed life was short. If the basin soil is too wet, it is easy to fall ill. 10 cm pots were transplanted 60-70 days after sowing and when the seedlings had 2-3 true leaves. Flowering can be seen 2-3 months after planting.

two。 Ramet propagation: from March to May. First pull out the mother plant, cut the underground stem into several sub-plants, each with new roots and buds, pot planting should not be too deep, root buds must be exposed to the soil. New buds without roots can hardly survive.

Cuttage propagation: dig out the robust plant, cut off the sturdy part of the root, remove the leaves, cut off the growth point, retain the root neck, plant in peat, keep room temperature 22-24 ℃, relative humidity 70%-80%, grow leaf buds and adventitious buds from the root neck to form cuttings. A mother plant can repeatedly cut cuttings 3 times and 4 times, and 10 cuttings can be picked. Inserted into the sand bed, it can take root in about 3-4 weeks. The new plants cut in the same year can blossom in the same year.

3. Tissue culture propagation: at present, leaves, unfertilized ovules, flower buds, stem tips, rhizomes and other materials are used as explants in Holland, the United States, Japan, Germany and other countries. The medium for bud differentiation was MS medium plus 2mg / L 6-benzylaminoadenine and 0.5mg / L indoleacetic acid. The subculture medium was MS plus 10mg / L kinetin, and the long root medium was 1/2MS + 0.03mg / L naphthylacetic acid. After the explants of African chrysanthemum were induced to sprout, after 4-5 months of test tube proliferation, a batch of test tube seedlings could be propagated and put into large-scale production.

With regard to the breeding methods of African chrysanthemum, I think you should know it. I hope the breeding methods of African chrysanthemum introduced above will be helpful for everyone to breed African chrysanthemum.

African chrysanthemum-African chrysanthemum culture method | African chrysanthemum picture | African chrysanthemum, African chrysanthemum, Compositae, (English name: Gerbera, Barberton daisy, etc.), alias Fulang flower, sunflower, gorilla, sunflower, etc., is a perennial herb, terminal inflorescence, flowers are red, white, yellow, orange, purple and so on. The method of sowing or planting is used for reproduction, and the country of origin is South Africa. African chrysanthemum language

The flower language of African chrysanthemum is: always happy, is a symbol of mystery, mutual respect and love, perseverance, not afraid of hardship.

The most commonly used flower language in China: elegance, elegance and seclusion.

The implication of African chrysanthemum: like to pursue a rich life.

Culture methods of African Chrysanthemum

1. Soil: gerbera is sensitive to water and should use a medium with good permeability and drainage, preferably a mixture of peat and perlite. The pH value is 5.5 to 6.0 and the EC value is 0.7 to 1.0, which is beneficial to the absorption of trace elements.

2. Watering: potted African chrysanthemum is very sensitive to water, so it must be watered at the right time, in the morning or evening, and make the plant relatively dry at night. When the plant begins to grow roots, it must be watered from the bottom, which can be infiltrated at the bottom; it can be watered from the top of the plant during high temperature, but care should be taken to prevent fungal mildew from the center of the plant.

How to raise Gerbera

Rizhao: like a sunny and well-ventilated environment.

Temperature: like warmth, belongs to semi-cold-resistant flowers. The suitable temperature during the growing period is 20-25 ℃, the optimum temperature in winter is 12-15 ℃, and the growth stops when the temperature is lower than 10 ℃. It can endure short-term O ℃ low temperature.

Soil: like loose and fertile, rich in humus, good drainage sandy loam, avoid heavy clay soil, like slightly acidic.

Moisture: avoid waterlogging.

Cultivation techniques of African Chrysanthemum

Key points of cultivation: pot cultivation is made of deep pot, 4 parts of rotten soil, 3 parts of garden soil, 2 parts of compost and 1 part of sand. When planting, the root neck should be slightly exposed to the soil surface, the seedling stage should keep the pot soil moist and squatting seedlings, the peak growth period should maintain adequate water supply, when watering during the flowering period, do not make the center of the leaves stained with water to prevent flower buds from rotting. The suitable ratio of nitrogen, phosphorus and potassium is 15:18:25, and the diluted liquid fertilizer is applied for 10 days, then the dilute cake fertilizer and water is added with potassium dihydrogen phosphate every 10-15 days, 0.1% boric acid is sprayed 2-3 times, and 1% potassium dihydrogen phosphate is applied before anthesis.

Disease control of African chrysanthemum

Diseases of Gerbera: 1. Botrytis cinerea

Treatment skills: humidity control is the key to the prevention and treatment of Botrytis cinerea. Remove the densely planted and overgrown leaves; increase ventilation and keep the air humidity at 75 per cent; water from below the canopy; in order to prevent water vapor from condensing on the flowers, open the side shed gradually after 10:00 in the morning to avoid a sharp rise in temperature in the shed; foliar spray of 1500 times of methyl topiramate was used in the early stage of the disease, and combined with aerosol for prevention and treatment.

The fengshui function of African chrysanthemum

1. The five elements are the lucky flowers of those who are on fire. For those who belong to fire in the five elements, African chrysanthemum is its lucky flower. In Chinese fengshui, it is believed that the species, attributes and placement of some plants can affect people's numerology, and plants can also be divided into yin, yang and five elements. If they are used properly in different directions and environments, they can play an unexpected regulatory role. It is believed in public opinion that plants are spiritual and can help in all aspects of human beings, so plants are commonly used to regulate the environmental aura, and the number of plants is numerous. The nature is also very different, so there are many exquisite when using such plants, such plants are called fengshui plants. People who belong to fire in the five elements should choose red as the main color, because red is the natural color of fire, or the natural color of wood is cyan. Because green wood is prosperous and prosperous, it can bring prosperity to homeowners and their families from the point of view of fengshui. Of course, in addition to red, African chrysanthemum has many other colors. African chrysanthemum is a lucky star for many people. With the change of color of African chrysanthemum, it blesses different people.

What is the price of African chrysanthemum?

Compared with the general rise in the prices of other flowers, the price of African chrysanthemum has not changed much, but since the second half of the year, the price of African chrysanthemum has remained high, mainly due to the slow recovery of production scale in the two major producing areas in the north and south and insufficient supply in the market. After entering winter, the quality of African chrysanthemum is getting better and better, and the low temperature reduces its flower yield by about 30%. The increase of winter consumption is also the main reason for the price stability of African chrysanthemum.
