Introduction to the breeding methods of Dianthus mandshurica

The florescence of carnation is generally from March to June, and the ornamental effect of group planting is better. The artificial cultivation of carnation is not difficult, in addition to sowing and propagation, it can also be propagated by ramet method.

Carnation

First, sowing and reproduction

If you want to start blooming in May, sow in January; if you want to blossom in spring after overwintering, sow in July-August (open-air cultivation), or sow in August or September (in glass or film greenhouse). Cover the flower seeds gently with vermiculite and maintain a balanced humidity. It takes 7 to 10 days to sprout at 20 ℃ ~ 21 ℃.

After the cotyledons were fully unfolded (Ⅱ during the growing period), the temperature decreased to 17 ℃ ~ 20 ℃, and the soil moisture decreased. 6-8 weeks after sowing, 1 seedling was transplanted into a flowerpot of 8 cm or 3 seedlings together into a flowerpot of 10 cm and 12 cm.

The upper basin matrix is loose and coarse-grained grass, and the pH value is kept at 5.8-7.0. The temperature is 13 ℃ ~ 17 ℃, frost-free at 3 ℃ ~ 5 ℃, or fabric mulching can be used in the open air. When the temperature is 15 ℃ ~ 18 ℃, it takes 10 to 11 weeks to blossom in spring. The low temperature of 7 ℃ ~ 12 ℃ will slow down the growth and prolong the growth cycle. Growth stops when the temperature is below 7 ℃.

2. Separate plant propagation

The suitable period is from autumn to winter. When ramet, dig out the clustered seedlings, separate them with a sharp knife according to 1-2 buds per plant, plant them in the basin, strengthen maintenance, and pay attention to heat preservation in winter.

The Culture method of Dianthus chinensis Propagation method of Dianthus chinensis

Carnation was originally grown in the seaside petals dry, small flowers gather to form a dense ball, group planting can form a very beautiful landscape. Next, we will tell you about the breeding methods and breeding methods of Dianthus chinensis.

The culture methods of carnation are as follows:

1. Soil

Potted plants should choose loose and well-drained soil, and when planting in a large area, we should choose places with high dryness and smooth drainage, and rotten leaf soil rich in organic matter is most suitable for the growth of carnation.

2. Temperature and light

The suitable temperature for the growth of carnation is 15-25 ℃. Sufficient light is required during the growth period, and proper shade is needed in hot summer. Scattered light is suitable (which can be moved to the shade of trees) to avoid hot sun exposure. Take cooling measures (sprinkling water, etc.) when the temperature is high.

3. Fertilizer and water management

Carnation does not have strict requirements for fertilizer and does not have much demand. It is usually applied once a week in 2-3 weeks. Watering should be appropriate, and the amount of water should be adjusted at any time according to weather conditions. Note: even when the air temperature is high, the water temperature is low, or the temperature is high after a long drought, if you pour a lot of water, it will cause damage to the roots of carnation.

The propagation methods of Dianthus chinensis:

1. Sowing and propagation of carnation.

If you want to start blooming in May, sow in January; if you want to blossom in spring after overwintering, sow in July-September. Maintain an ambient temperature of about 20 ℃ and sprout in 7-10 days. After the cotyledons were fully expanded, the temperature was reduced to 17 ℃-20 ℃, and the soil moisture was reduced. 6-8 weeks after sowing, one seedling was transplanted into an 8-15 cm flowerpot, or 2-3 seedlings were transplanted together into a 10-12 cm flowerpot. The upper basin matrix is loose and coarse-grained grass, and the pH value is kept at 5.8-7.0. When the temperature is 13 ℃-17 ℃, frost-free overwintering should be taken to keep warm in winter. When the temperature is 15 ℃-18 ℃, it takes 10-11 weeks to blossom in spring. The low temperature of 7 ℃-12 ℃ will slow down the growth and prolong the growth cycle. Growth stops when the temperature is below 7 ℃.

2. Separate propagation of Dianthus caryophyllus

The suitable period is from autumn to winter. When ramet, dig out the clustered seedlings, separate them with a sharp knife according to 1-2 buds per plant, plant them in the basin, strengthen maintenance, and pay attention to heat preservation in winter.

Flower name: Carnation alias: Genus Caryophyllus of Blue Snow Family

Carnation

Germination conditions (temperature, soil cover, light requirement, etc.): 20-21 ℃

Days required for germination: 4-10 days

Suitable temperature for growth (daily temperature / night temperature): 10-13 ℃

Light demand for growth and other growth conditions: partial shade or partial light

According to the morphological characteristics, the flowers of Celastraceae have low, tufted plants, and the plant height is only 8 2cm. Leaves linear and long sword-shaped, entire, dark green; spring flowering, head terminal. The flower stem is slender and the florets gather at the top of the flower stem. It is semi-spherical and purplish red.

Reproduction and cultivation, the method of plant division is used, and the suitable period is from autumn to winter. The rotten leaf soil rich in organic matter is the best cultivated soil. Drainage and lighting should be good. Sexual warmth is preferred, high temperature and humidity are avoided, and the suitable temperature for growth is 1 5-25 ℃.

Main habits: tufted herbs for many years, 20-30 cm high, leaves lined, pink to rose-red flowers, terminal head-shaped inflorescences, flower stems about 3 cm, sowing or ramet reproduction, sexual preference for sandy soil with adequate sunshine and good drainage, can be used as flower beds, flower borders, rock gardens, cut flowers and potted flowers.
