Propagation methods and matters needing attention of echinacea

Because the flowers of echinacea are large and colorful, among the flower varieties that afforest and beautify the environment, echinacea is a kind of flower species that is easy to be concerned, and it belongs to the wild flowers of Compositae. Now the ornamental value of echinacea is very high, so what methods can be used for artificial reproduction of echinacea? What problems should we pay attention to?

Echinacea

1. Sowing and propagation: sowing can be carried out in late April in spring or early September in autumn. After leveling the depth of the seedling bed in the open field, pour through water, sow seeds after all the water seeps into the ground, keep sowing about 1000 seeds per square meter, control the temperature at about 22 ℃, and seedling can emerge in 13 days. The seedlings were transplanted when they grew to 2 true leaves.

2. Ramet propagation: for perennial mother plants, it can be propagated in spring and autumn. Each plant needs 4-5 terminal buds to be cut off from the rhizome and then planted and managed.

3. Cutting propagation: large mother plants should be prepared for cutting seedlings, which should be put in the greenhouse in winter, strong branches should be taken in early spring, and 2-4 true leaves should be retained without growing point. The length of the branch is 5~6cm, and the shearing mouth should be under the node and cut as soon as it is cut. The cutting depth is the length of cuttings: 1ax, 3cm, 1ax, 2. It is required that the inserting machine should not be too wet, and the air humidity should be high, and it can take root in 20-30 days at a temperature of 22 ℃.

How to raise echinacea? Culture methods and matters needing attention of echinacea

Echinacea is a perennial herb of the family Compositae. It is one of the indispensable flower varieties in courtyards and parks. It has high ornamental value. At the same time, echinacea also has a certain medicinal value, and has a good therapeutic effect on colds, cough, respiratory tract infection and other diseases. So, how to raise echinacea? The breeding methods and matters needing attention of echinacea are introduced as follows.

I. Culture methods of echinacea

1. Lighting: echinacea belongs to long-day plants. During flowering, echinacea needs 16 hours of light per day for 14 Mel and 8 weeks of intense light for 7 Mel. In northern China, it usually blossoms in late May and lasts until September.

two。 Temperature: during the growing period, the temperature of echinacea should be kept at 16 ℃-24 ℃ during the daytime and 10 ℃-16 ℃ at night.

3. Fertilization: the nitrogen concentration of water-soluble fertilizer was 50-75rrg/kg from radicle appearance to cotyledon expansion, 100-150mg/kg when cotyledon developed to 4 true leaves, and 250mg/kg after planting. It could be applied twice a week.

4. Moisture: echinacea is strong and resistant to drought, so watering should follow the principle of "dry and wet". Wait until the basin soil is dry, and then water it thoroughly at one time.

5. Soil: echinacea is not strict on soil, but it grows best on deep, fertile, humus-rich soil.

6. Cold prevention and overwintering: echinacea should be watered with anti-freezing water before winter. it should be covered with plastic sheet within 2-3 days after watering, and some firewood or grass should be covered properly in case of cold current. Finally, use the soil to press the edge of the cover to prevent it from being blown by the wind.

Matters needing attention in the culture of echinacea

1. Reasonable fertilization: 0.05% magnesium sulfate should be supplemented twice to prevent magnesium deficiency in plants. Also supplement 1Mel twice chelated iron to prevent iron deficiency. It is suggested that long-acting slow-release fertilizer should be added to the basin soil when planting.

two。 Cold prevention and ventilation: when the temperature in the northern region is relatively low in November, the echinacea needs to be moved indoors for maintenance. If the room temperature is above 0 ℃, the echinacea can grow healthily; put the echinacea in a ventilated and ventilated place to maintain ventilation.

[conclusion] echinacea likes a warm environment, strong and hardy. However, in order to promote more blossoms and good blossoms, it is necessary to do a good job of maintenance. The above introduces the breeding methods and matters needing attention of echinacea. I hope it can be helpful to you!

Culture methods and matters needing attention of echinacea

Cultivation methods of echinacea under light

Echinacea is a long-day plant, in the flowering stage of the plant to ensure 16 hours of light a day, but also need to maintain 8 weeks of high-intensity light, the northern region generally blossoms in late May, the flowering period can last until September.

Temperature

During the growing period, the temperature of echinacea should be kept at 16 ℃-24 ℃ in daytime and 10 ℃-16 ℃ at night.

Fertilizer application

The nitrogen concentration of water-soluble fertilizer was 50-75rrg/kg from radicle appearance to cotyledon expansion, 100-150mg/kg when cotyledon unfolded to 4 true leaves, and 250mg/kg after planting.

Moisture content

Echinacea is strong and resistant to drought, so watering should follow the principle of "dry and wet". Wait until the basin soil is dry, and then water it thoroughly at one time.

Soil

Echinacea is not strict on soil, but it grows best in deep, fertile and humus-rich soil.

Matters needing attention in echinacea culture rational fertilization

Appropriate supplement of 0.05% magnesium sulfate 1Mel 2 times to prevent magnesium deficiency in plants.

Also supplement 1Mel twice chelated iron to prevent iron deficiency.

It is suggested that long-acting slow-release fertilizer should be added to the basin soil when planting.

Pay attention to cold prevention in winter

In November, the temperature in the northern region is relatively low, it is necessary to move the echinacea into the room for maintenance, keep the room temperature above 0 ℃, the echinacea can grow healthily.

Pay attention to ventilation

Put echinacea in a ventilated and breathable place to maintain good ventilation.
