Sowing and raising seedlings of Dianthus chinensis

Dianthus caryophyllus is a perennial herb of the family Caryophyllaceae. It has a wide variety of flowers and colors, and is mainly sexual reproduction.

When raising carnation seedlings, choose a flat and dry place with 15 kilograms of compound fertilizer, deeply turned, smashed and leveled and sealed a 1-meter-wide bed. Irrigate once and sow the seeds immediately after the water seeps. After sowing, cover with a layer of fine soil, build a small arch shed, cover with plastic sheeting, the suitable temperature in the shed is 20 ℃ to 26 ℃, so that seedlings can emerge in about 10 days. After emergence, we should pay attention to ventilation to prevent prosperous growth, in order to achieve the purpose of refining seedlings. After half a month of seedling training, remove the plastic sheeting on a cloudy or cloudy afternoon, remove the weeds, pay attention to the control of green insects and aphids, and plant separately after 2 to 3 months. This method is suitable for wheat harvesting from thawing in spring. 0.5 kg per mu of sandy soil, 0.6 kg of clay and 0.9 kg of engineering land. The utility model has the advantages of high seedling rate, saving seeds, and can make the seedlings come out of the nursery ahead of time. The disadvantage is: the cost is labor, and the cost is slightly higher.

Direct seeding can also be used to raise carnation seedlings: after fertilizing, turning deeply and leveling the seedling land, spread the seeds evenly on the surface and hold each side of the rake vertically and horizontally. Do not hug too hard, and then it is best to roll it over again or step on it manually, and then spray water to keep warm. The number of times of spraying water can be determined according to soil moisture and weather, generally spray once or twice a day, spray more in sunny days, spray less or not in cloudy days, and seedlings can emerge in about two weeks. After emergence, management should be strengthened, weeds should be removed in time, and drainage should be paid attention to in rainy days. This method is suitable for use from wheat harvest to soil freezing. 0.6 kg per mu of sandy soil, 0.8 kg of clay, and 1.3 kg of engineering land is suitable. In addition, the sowing rate can be determined according to soil structure, soil quality and planting requirements. Its advantage is: no need to transfer seedlings, can save a lot of labor, the disadvantage is: slightly cost seeds.

In Heilongjiang, Jilin, Liaoning, Inner Mongolia, * and Dunhuang, Gansu, the live broadcast should be arranged 50 days before the soil is frozen. Otherwise, it is disadvantageous to the overwintering of carnation. With the exception of protected cultivation, of course.
