Cultivation and culture methods of echinacea

Echinacea is a perennial flower that grows well in the north, blooming from 5 to October. Like warm sunny, although suitable for fertile soil, but also resistant to thin, resistant to semi-shade, afraid of water and dry early, and good resistance. Strong growth, adaptability and resistance. Long florescence, high ornamental value. It is best to overwinter indoors in winter, and the overwintering temperature shall not be lower than 5C. In the first growth period to keep the soil moist, summer flowering before, should be appropriate irrigation, and apply liquid fertilizer, can prolong flowering. Pay attention to drainage in rainy season and prevent plant lodging. After flowering, timely pruning of residual flowers can prolong the viewing period.

Echinacea capitate terminal, the main flower stem flowers open first, and then axillary buds sprout lateral flower stems, forming flower buds, when the fertilizer and water conditions are sufficient, gradually stem flowering, flowering up to 2 months, single flower life about 10 - 15 days. In order to maintain a better viewing effect, it can be timely removed to promote the formation of lateral flowers, and then removed again to form secondary lateral flowers. Topping can also dwarf plants and prevent lodging.

Echinacea is commonly used in seeding and rationing

Sowing and cultivation can be carried out in spring and autumn, the germination of seeds is suitable for 20 - 22cc, keep the bed surface wet, and germinate 3 weeks after sowing. Early spring April can be in the open field direct seeding, normal management, July-August can bloom. It is planted in September and October and can bloom in May of the following year. The ramets are also carried out in early spring or late autumn, and the plants cultured by ramets recover quickly and have high survival rate.

Attention should be paid to cultivation:

3-6 Keep watering during the growing season to keep the soil moist. The flowering period is controlled by post-flowering pruning, such as post-flowering pruning in April and May, and fertilization management is strengthened. The second flowering can be achieved in July and August; post-flowering pruning and fertilization watering can be achieved in May and June, and the second flowering can be achieved in September and October.

Cultivation Techniques of Echinacea

Echinacea, Echinacea purpurea Compositae, Echinacea is native to North America, famous countries are cultivated. Plant height 60-150cm, whole plant with coarse hair, stem erect. Basal leaves ovate or triangular, petiolate, cauline leaves ovate-lanceolate, slightly amplexicaul. The capitulum is solitary branch top, diameter is about 10cm, ligulate flower is purplish red, tubular flower is orange yellow, outstanding assumes globose, florescence late spring to autumn.

Sexual preference warm sunny environment, cold-resistant, rich in humus soil requirements fertile and deep. Sowing and breeding can be carried out in spring and autumn. It can also be cultivated in early spring or late autumn. It is suitable for natural planting of wild flowers, and can be used as cut flowers with other flowers. Cultivation and Management of Echinacea Echinacea, also known as echinacea, chrysanthemum shape, rich in color and luster, for the composite perennial herbs. Echinacea can be used as cut flowers, but also a good large potted plant, while its flowers are very large, up to 15 cm in diameter, is a good material for the production of dried flowers.

1. Methods of reproduction. It is mainly seeding propagation, ramet propagation and cuttage propagation, mainly seeding propagation. (1) Sowing and propagation: Sowing can be carried out in late April in spring or early September in autumn. After deep turning and leveling of the open field seedbed: watering thoroughly, sowing seeds after all the water penetrates underground, maintaining an area of 4 square centimeters for each seed, controlling the temperature at about 22℃, and germinating in 2 weeks. When seedlings grow to 2 true leaves, seedlings are transplanted. Planting occurs when the seedlings are about 10 cm tall. Plant spacing is 40×40 cm. (2) Plant division propagation: For perennial mother plants, plant division propagation can be carried out in spring and autumn. Each plant needs 4-5 terminal buds to be cut off from the rhizome. (3) Cutting propagation: take about 5 cm long tender shoots, insert them into the sand bed with leaves, and require that the cutting bed should not be too wet, and the air humidity should be high, and root in 3-4 weeks under the temperature of 22℃.

2. Cultivation management. No matter the plants divided or sown, the sunny environment should be selected when planting, and the decomposed manure or a certain amount of bone meal and sesame residue should be added after deep ploughing of the soil. The planting plants are determined according to the needs of plant spacing and watered thoroughly. Fertilizer and water should be added during growth period. Close to flowering can be sprayed twice potassium permanganate liquid fertilizer leaves, the color is beautiful and lasting, plant shape plump symmetry. For overwintering plants in the open field, residual flowers and dead leaves should be removed after flowering, enough frozen water should be poured or the underground part should be covered with compost or choked soil. To make Echinacea bloom more, two methods can be adopted: sowing by stages and pruning in time after flowering.

(1) Sowing by stages: If sown in autumn of the first year, it can bloom at the end of April or early May of the next year, and the flowering period can last for two months; sowing in greenhouse in early spring, flowering in July and August; sowing in May, flowering in September; sowing in June, flowering in October. (2) pruning residual flowers to regulate flowering period. Such as pruning after flowering in June, while giving good fertilizer and water conditions, to September-October can bloom again.

Potted echinacea, potting soil needs loose fertile mixed soil or culture soil. When planting, 3-5 seedlings can be planted in each pot depending on the size of the pot. It needs to be picked once in the early stage of growth to promote branching. It is good to renew cultivated plants once a year. Watering should not be too much, plum rain season, air humidity should be controlled when watering. During the growth period, thin liquid fertilizer should be applied to promote growth. Fertilize once a week when buds are formed. Sprinkle water after each application to avoid fertilizer sticking to the plants. In order to shelter from rain, cultivation is generally carried out in greenhouses, which should be placed in a well-ventilated and sunny place. The lowest temperature should not be lower than 10℃, and proper shade should be provided in hot summer.
