How to keep a good pot of carnations (maintenance and precautions of carnations)

Dianthus is a perennial herb flower of Dianthus, also known as Luoyang Flower, Dianthus China, Dianthus China and Dianthus. Dianthus is a good ornamental flower, with purple, pink, bright red or white flowers, and the flowering period is from April to May. Deeply loved by flower lovers.

Carnation originated in China, which is cold-resistant, drought-resistant, heat-resistant, sunny, highly dry and well ventilated. It often grows poorly or withers in summer, so attention should be paid to shading and cooling during cultivation. I like sunny, dry, ventilated and cool and humid climate. It requires fertile, loose and well-drained calcareous loam or sandy loam to avoid waterlogging and be fertile.

First, the propagation method of carnation: carnation mainly propagates through sowing, cutting and ramet propagation.

1. Sowing and propagation: Sowing is generally carried out in autumn and September every year. You can sow seeds directly in the yard or transplant seedlings. The sowing method is usually drill sowing, furrow sowing or box surface sowing. It's best to cover the soil after sowing, so that the seeds can't be seen. Cover with straw curtain or plastic film to keep the bed soil moist. The suitable temperature for germination is 20℃, and Dianthus caryophyllus can germinate and emerge about one week after sowing. The optimum temperature for seedling growth is 10-20℃. When carnation seedlings grow two or three true leaves, they should be thinned, and the weak seedlings, clustered seedlings and miscellaneous seedlings should be removed and transplanted. Plant spacing10cm, row spacing16cm. Keep air circulation and plenty of sunshine, so that Dianthus caryophyllus seedlings can grow rapidly. 1-2 after transplanting, carnation seedlings can be planted when they grow to 4-5 leaves, and can bloom in the next spring.

2. Cutting propagation: cutting propagation can be carried out throughout the growing season, generally from March to 10, and cutting can be carried out at room temperature above 10℃ in early spring and early winter, so that leaves can take root and survive. Sieved cinder, river sand, vermiculite, etc. Seedbed. Cut branches with a length of 5-6 cm from the tender branches as cuttings. After the cuttings are inserted into the substrate, the leaves at the base of the cuttings are removed 1/4 to avoid stem rot, and the burial depth is about 1/3 of the cuttings' length. The optimum cutting temperature is about 65438 05℃. After cutting, the seedbed should be kept moist to avoid water accumulation. Shading is needed in high temperature season, but plastic film arch shed can be used to keep warm and moisturize at low temperature, and take root after 15-20 days of cutting.

3. Propagation by dividing plants: The old plants are often divided into plants after flowering, which can be carried out in autumn or early spring. Usually in the middle and late March of spring, when carnation germinates new buds, the old plants can be dug out, the existing roots and lateral buds of the old roots can be cut off, the incision is smeared with plant ash, and transplanted into a seedbed for culture. Pay attention to drainage in summer, strengthen fertilizer and water management after September, and 10 blooms again at the beginning.

2. Planting in the open field: When carnation seedlings have 4-5 true leaves, or when cuttage seedlings survive, if continuous planting, the row spacing between plants is about 10 cm. Don't plant it too closely, so as not to affect ventilation, and powdery mildew will be serious in the later stage.

3. Potting: Potting is usually carried out in spring and autumn. First, spread the broken tiles on the bottom of the pot, then fill in the culture soil, and then put the carnation seedlings or plants with cut branches or branches into the center of the pot bottom to stand upright, and the roots should be stretched. Fill the soil into a half pot, gently lift and shake the carnation plants, and compact the cultivated soil. Don't plant it too deep, just keep the roots and the mouth of the pot flat. Shallow affects the survival, and deep affects the growth of carnation after transplantation. Water it once after planting. After cultivation, it should be maintained in a cool environment for about a week, and then moved to the sunny place after the root system is restored.

Fourth, water and fertilizer management, carnation seedlings should be watered frequently after transplanting to keep the soil moist. Thin decomposed human manure water, decomposed cake fertilizer water and other topdressing are commonly used, and cow and pig manure can also be dried with cake fertilizer powder and a small amount of ammonium sulfate or urea. , and dispersed in the rows, fully mixed with the soil. Topdressing every 7- 10 days during the growth period can promote the flourishing of lateral flowers. It is dry in summer, so water it frequently in the morning and evening.

5. Keeping the soil loose, reducing water evaporation and promoting air circulation are important tasks to ensure the rapid and robust growth of Dianthus caryophyllus seedlings. Pay attention to seed collection after flowers wither. The seeds of carnation seedlings are not mature evenly, so it is necessary to collect seeds in stages and batches. Seeds should be picked in the morning with dew, dried and stored in a ventilated and dry place for sowing in the next year.
