The Culture method of Medal Flower

Medallion flowers, also known as medallion chrysanthemum, are Compositae plants. Medallion flowers native to South Africa need to be cultivated in China if they are planted in China. If you want to raise medallion flowers well, you should not only understand the life habits of medallion flowers, but also master certain skills. The following will give you a detailed introduction-the breeding methods and key points of medallion flowers.

Morphological characteristics of medallion flowers

The flowers of the medallion are annual herbs. Rhizomatous. The leaves are clustered by the rhizosphere, lanceolate or Obovate-lanceolate, entire or shallowly pinnatifid, and the back of the leaf is densely covered with white wool. The tongue-shaped flowers are white, yellow and orange-red with luster. The common varieties of medal flowers are dawn series and early flowers, which bloom 7-20 days earlier than all medal flowers. The flowers are yellow, orange, reddish brown, pink, white and orange / yellow, among which the new varieties are fresh orange and red stripes.

The planting of medal flowers

Potted medallion flowers are often used in 12-15 cm pots, and the potted soil can be mixed with rotten leaf soil, stable fertilizer soil and coarse sand. The seedlings can be put on the pot when they grow to 4-5 pieces.

The main points of potted medal flowers

Potted medallion flowers are cultivated in pots of 10 to 16 centimeters and in a well-drained medium with ph values of 5.8 to 6.2 and EC values of 1.0 to 1.5. The potted soil is kept dry and watered each time after the pot soil is dry. Watering medallion flowers should be carried out in the morning in order to keep the leaves dry at night and prevent diseases. Too much water will produce overgrowth, too dry will blossom early, and it is easy to burn leaves in strong light.

Postpartum treatment of planting medallion flowers

The tongue-shaped petals of medals are novel. The flowers open to the sun and close after sunset. It is very interesting. Use potted medallion flowers to put flower beds or lawn edges, + points natural harmony. Decorate a small garden or windowsill, like a funny face, ludicrous. Of course, medal flowers are also a good material for flower arrangement.

Potted medallion flowers are cultivated in pots of 10 to 16 centimeters, cultivated in a well-drained medium, keep the potted soil dry, and then water each time after the potted soil dries. Watering medallion flowers should be carried out in the morning in order to keep the leaves dry at night and prevent diseases. Too much water will produce overgrowth, too dry will blossom early, and it is easy to burn leaves in strong light.

The important points of watering medal flowers

Keep the soil moderately moist during growth.

The temperature and light of medal flowers

Under the condition of sufficient light and suitable temperature, it can blossom continuously. If there is no seed, cut off the residual flowers in time after the flowers are shed, which will help to form more buds and blossom more.

Key points of fertilization for planting medallion flowers

Fertilize once every half month or so, use Huiyou 15-15-30 special fertilizer for potted flowers or rotten cake fertilizer and water.

Pest control of medallion flowers

The common harm of leaf spot disease can be sprayed with 1000 times of carbendazim wettable powder.

Insect pests are harmful to red spiders and aphids. Aphids are sprayed with 2.5% fish rattan essential EC 1000 times, and red spiders are sprayed with 40% omethoate EC 1500 times.

The propagation of medallion flowers

Medallion flowers are commonly propagated by sowing, ramet and cutting.

The seeds can be sowed in spring in April or autumn in September, the optimum temperature for germination is 16-20 ℃, and germinate 15-25 days after sowing. When the seedlings grow a pair of true leaves, the seedlings are transferred for the first time.

The ramet of medallion flower is usually dug up before the leaf cluster germinates in March-April, and the overwintering mother plant is dug out and cut longitudinally from the root neck of the plant cluster with a sharp knife. Each ramet with bud head and root system can be potted directly.

The cutting propagation of medallion flowers can be carried out in spring and autumn, cut the buds with stem nodes, leave the top two leaves, insert them into the sand bed, keep the substrate moist, and take root 20-25 days after cutting at 20-25 ℃. If 0.1% indole butyric acid is used to treat cuttings for 1-2 seconds, rooting is faster.

Detailed explanation of the Culture method of Medal Flower

The medal flower generally refers to Xun Zhang Ju.

Medal chrysanthemum (scientific name: Gazania rigens) also known as: medal flower, African sunflower, belongs to Compositae, Compositae perennial root herbs, flowering from late spring to early summer, leaves clustered, lanceolate, Obovate-lanceolate or oblate linear, entire or shallowly pinnatifid, leaves densely covered with white woolly. Flower diameter 7~8cm, ligulate flowers white, yellow, orange-red, glossy, florescence from April to May. Native to South Africa and Mozambique, it is suitable for flower beds and flower borders. Because of its entire inflorescence such as medals, it is named Medal Ju. Like sunshine, like to grow in cooler places, drought-resistant, barren soil; semi-cold-resistant, so you can survive the winter smoothly in mild winter areas.

The breeding method of medallion flowers is basically similar to that of ordinary flowers, but it also has some of its own characteristics! Sowing, plant division, cutting and tissue culture are commonly used. Sowing and breeding: spring sowing in April or autumn sowing in September, 560-580 seeds per gram, germination temperature 16-18 ℃, germination 14-30 days after sowing. The seedling has a 4 cm seedling plate with a pair of true leaves. Seeds in some areas have the ability to self-sow and reproduce. Ramet culture: before the growth of stems and leaves from March to April, the overwintering mother plant was dug out and cut longitudinally from the root neck of the plant cluster with a knife, but each ramet must have bud head and root system and can be potted directly. Cuttage culture: often carried out in spring and autumn, indoor cultivation can be carried out all the year round. Cut the buds with stem nodes and leave the top 2 leaves. If the leaves are too large, you can also cut off 1 big 2 to reduce the evaporation of foliar water. Insert sand bed, room temperature 20: 24 ℃ and maintain high air humidity, rooting 20-25 days after insertion. If treated with 0.1% indole butyric acid for 1 / 2 seconds, rooting is faster. Tissue culture: stem tips and buds are commonly used in explants. After disinfection, the shoot tip was inoculated on MS medium supplemented with 6-benzylaminoadenine 1mg / L and naphthylacetic acid 0.2mg / L to induce callus and differentiate buds. Then transferred to MS medium with 1 mg / L naphthalene acetic acid and cultured for 30 days and 40 days, the seedlings rooting and formed complete plantlets. Sowing in spring or autumn, slightly covered with soil, good moisturizing, about 7-10 days germination ramet. The period of bud insertion is about April or October, and the ramet divides 2-3 buds into one plant. Planting is carried out in early spring, and each bud is planted in well-drained soil. Medallion chrysanthemum, also known as medallion flowers, common high-quality varieties are: dawn series. Clown series and kiss series. The flowers are colorful, bright and beautiful, the petals are full of luster, open day and night, very interesting, is a very good flower bed flower path edge material and flower arrangement material. The main common disease of medallion chrysanthemum is leaf spot. The disease should be prevention-based, can use 25% carbendazim 1000 times solution, foliar spray. If the disease has occurred, to use 800 times liquid foliar spray, once every 7 days, 2-3 times in a row, can be basically cured. The main pests of this flower are black and red mites and aphids. It's a piercing pest. This kind of pests can be sprayed with imidacloprid and its improved dosage forms, such as Wanlihong, Dinghong and so on. At present, as a variety of potted flowers and flower beds in China, imported F1 hybrid seeds are mainly introduced for sowing and breeding in order to ensure the consistency and high efficiency of the varieties. In addition, medallion chrysanthemum can also be cultured by ramet and cuttage. Ramet culture. Before the growth of stems and leaves in spring, the overwintering mother plant was dug out, poured out of the flowerpot, cut longitudinally at the root neck of the plant cluster with a knife, and divided into several clumps, each with buds and roots. Cuttage culture. Indoor cultivation can be cut throughout the year, and open-field cultivation can be cut in the cool spring and autumn season. Use buds as cuttings, leaving 2 leaves at the top. If the leaves are large, you can cut off 1 beat 2 to reduce water evaporation on the leaf surface. Insert a 50-hole hole tray or insert it directly into the sand bed, control the temperature from 20 ℃ to 25 ℃, maintain a high air humidity, and generally take root 20 to 25 days after cutting. If dipped in 1000 mg / kg indole butyric acid solution for 1 to 2 seconds, rooting can be accelerated. After rooting, it can be cultivated in a flowerpot with a diameter of 8 to 12 cm.
