The main points of sowing and propagation of thousand-day red

Thousand-day red flowers are colorful, and the flowers do not wither after they are dried and remain unchanged for a long time, so they are deeply loved by people, so it also symbolizes eternal love and immortal love. Now people will arrange the former daily use in the flower bed, flower border, but also natural dried flowers, the economic value is relatively high.

Thousand days red

Thousand-day red sowing generally chooses spring sowing. The seeds should be soaked before sowing in the open field nursery bed from March to April. The method is to soak the seeds in cold water for 1-2 days, remove and squeeze them dry, mix them with plant ash or fine sand, and then rub the seeds open before sowing. Under the temperature of 20 ℃ to 25 ℃, the seedlings can emerge about 10-14 days after sowing. The germination rate of dwarf varieties is low. The suitable temperature for growth was 15: 30 ℃, and flowered at 9: 10 weeks after emergence. Seedlings with 2 to 3 true leaves are transplanted once, and can be planted in the flower bed in the first and middle of June, with a distance of 30 cm; if potted, they can be planted in the early budding stage. Hongsheng has strong growth, lax requirements on fertilizer, water and soil, and simple management. Generally, fresh liquid fertilizer is applied once or twice at seedling stage, and liquid fertilizer rich in phosphorus and potassium is applied twice to 3 times at flowering stage, then flowers and leaves flourish, brilliant and colorful. During the seedling period, several "topping" pruning should be carried out, that is, two pairs of new leaves should be retained each time, and the top should be pinched off, but the neat and beautiful shape of the plant should be taken care of when pinching the top. After the residual flower is faded, it can not bear seeds, it can be reshaped and pruned, it can still sprout new branches and blossom again in late autumn, but it needs more thin fertilizer.

The sowing method is mainly used: sowing in the open field seedbed from April to May, for example, from March to early April, due to low air temperature, poor germination and slow growth, the germination temperature is 16 ℃:-25 ℃, 7-10 days after sowing, seedlings: the initial growth is slow, the growth is accelerated after June, the seedlings are transplanted when there are 3 pairs of true leaves, planted in the open field after the middle of June, the plant distance is generally 30cm. The potted plant can be planted in a pot with a diameter of IOcm when it grows 3 pairs of true leaves, and then turn to a pot with a diameter of 16cm-20cm.

It is difficult for red seeds to germinate, soak the seeds in warm water for half a day, then sow the seeds, keep the culture soil moist, and germinate ahead of time.

Key points of breeding management of thousand-day red

Thousand-day red, also known as thousand-year-old red, fireball flower, is an annual herbaceous flower of amaranth family. Because the color and pattern of thousand-day red remain unchanged for a long time, so its viewing period is relatively long. So what do we need to pay attention to in the breeding management of thousand-day red?

Thousand days red

Thousand-day red is native to China and India. It is not strict with the environment, but it likes sunshine, hot and dry climate, and is suitable for growing in loose, fertile and well-drained soil.

Red seeds are propagated for thousands of days, collected from September to October, sown from April to May, and planted in June. Seeds are crispy fruits with perianth, appearance hairy. Soaking seeds in cold water for 2 days before sowing can increase the emergence rate. The soaked seeds are slightly dried and mixed with plant ash before sowing. After seed germination, topping and pruning should be carried out several times in the seedling stage, which can promote the plant to be more branched, flowering and dwarf. Then the short and dense internodes were selected for plant cultivation in order to maintain the excellent varieties. Appropriate fertilization and watering should be applied during the growing period, and attention should be paid to weeding in the middle of ploughing and drainage in the rainy season.

Potted plants should be kept moist and shaded after thousands of days of potting. Topdressing is carried out in combination with watering during the growing period. This flower has lax requirements on fertilizer, water and soil, and its management can be more extensive. After pruning and pruning, the residual flowers can still sprout new branches and blossom again in late autumn, but more thin fertilizer should be applied.

2. Pruning in August, the hedges in the courtyard, such as boxwood, lobular privet, privet, golden leaf privet, French holly, spinulosa heather, etc., should continue to be pruned. Balls planted on the ground, such as heather, dragon cypress, Shu juniper, bayberry, pyracantha, Haitong, wolfbone, holly, etc., must also be pruned. For flowers and trees that bloom continuously for a long time, such as rose, pomegranate, hibiscus, crape myrtle, Fusang, triangular plum, five-color plum, etc., the residual flowers should be picked in time, and the branches and tips should be appropriately shrunk. Grass flowers planted on the ground, such as a string of red, thousand-day red, early chrysanthemum, peacock chrysanthemum, marigold, etc., should be topped and picked from the heart.

3. Watering in August, watering and spraying management should be strengthened for flowers and shrubs transplanted in spring and grass flowers planted in spring.

1. Watering in August should be between 9 and 10:00 in the morning and after 4 o'clock in the afternoon to keep the water temperature basically consistent with the soil temperature and air temperature. For those ornamental plant species that like acidity, 0.1% ferrous sulfate can be added to the irrigation water. It is worth noting that for ornamental plants with dense hairs on their leaves, such as Baobao, Tripterygium, Tripterygium, Begonia, etc., the leaves are not easy to evaporate after droplets, which can easily lead to leaf rot, and only a small amount of spray is feasible; the flower buds of Fulang flower (African chrysanthemum) and the leaf center of Magnolia can not be drenched with water, and the flow of dirty water into the leaves will cause heart damage. Pineapples must be watered less, sprayed more, and injected water into the leaf tube in order to meet their needs. When watering and spraying potted plants this month, you must pay attention to loosening the soil, but every 10 days, otherwise it will lead to pot soil hardening due to repeated watering. For dormant and semi-dormant flower species, watering and spraying should be controlled to keep the basin soil slightly moist, and a relatively cool environment can be created by spraying water around the flowerpot.
