What are the breeding methods of Zou Ju

Zou Ju

Zou Ju, also known as Chunju and Sunflower, originated in Europe. In the early years, Zou Ju was regarded as a weed. Later, it was found to be a perennial herb with a flowering period in spring and is now the national flower of Italy. In China, the cultivation rate of Zou Ju has been increasing, so do flower friends know the breeding method of Zou Ju?

1. The growth habits of Zou Ju

Daisies like cool climate and avoid hot. Like light, but also resistant to semi-shade, the cultivation of soil requirements are not strict. The optimum temperature for seed germination and growth was 22-28 ℃ and 20-25 ℃ respectively. It is suitable for planting single or semidouble varieties of medium and small flowers in southwest China. The double petal varieties of medium and large flowers grow weakly and seed poorly.

2. Breeding methods of Zou Ju

Many methods can be used, such as ramet, cutting, grafting, sowing and so on. Grafting and sowing methods require high technical conditions, and the reproduction process is relatively tedious. Without superb cutting, grafting techniques, selection of improved varieties, artificial pollination and other techniques, it is difficult to propagate successfully. These two propagation methods, only when a large number of seedlings are needed, carried out in the nursery, family chrysanthemum, generally use split-plant method and cutting method to propagate.

1. Seed propagation

Most of the seeds in the south are sown from August to September in autumn, or in spring, but they often grow poorly in summer. In the north, most of the seeds are sown in spring or in autumn, but the flower seedlings need to be transferred to the greenhouse for cultivation and management in winter. Because the seeds of daisies are relatively small, they are usually sown. However, sowing seedlings often can not maintain the characteristics of the mother plant. Before sowing, apply enough rotten organic fertilizer as the base fertilizer, and turn the rake deeply to make a flat bed. Sow the seeds with fine sand, cover the fine soil with a thickness of about 0.5 cm, cover the sunshade net and water thoroughly after sowing. Keep the temperature around 28 ℃ after sowing and cover with plastic film when it is cold and rainy in early spring to maintain soil moisture and temperature. Watering should be sprayed carefully to prevent soil surface hardening. After about 10 days, the seedlings are unearthed, remove the sunshade net or plastic film, and can be transplanted to the field when the seedlings have 2-3 pieces. Chrysanthemum cauliflower can be sown directly, sowed in February in southern China, and sown in early April in cold areas in the north, with a seed consumption of about 0.2 kg per mu.

two。 Ramet propagation

Because of the great variation of seedlings, the split-plant method can be used to propagate some excellent varieties, but the growth potential is not as good as that of seedlings, and the fruiting is poor. In the middle and late March, the old stubble chrysanthemum cauliflower can be dug out to expose the root neck, and the lateral buds of the existing roots together with the old roots can be cut off and transplanted to the field. Ramet propagation is more suitable for sprouting new shoots.

3. Cuttage propagation

Cutting propagation can be carried out throughout the growing season, and the survival rate of cutting from April to June is the highest. It is best to mix new soil with rotten organic fertilizer in the seedbed. Cut the branches with 3-5 nodes and 8-10 cm in length, remove the basal leaves, and dig into the soil at the depth of 1 stem 3-1 bank 2 with long cuttings. Keep the work bed moist and avoid waterlogging after cutting. shade is needed in high temperature season, and plastic film arch shed can be built to keep warm and moist when the temperature is low. Generally, it can be transplanted to Daejeon after 15 days.

Daisies grow strongly and are easy to cultivate. Daisy pedicel is of moderate height, neat flowers, bright and clean colors, can be used as potted plants to beautify the courtyard balcony, can also be used as garden ornamental, potted plants, flower borders, cut flowers and so on. With long flowering period and strong cold tolerance, it is the first choice for ground cover flowers in early spring. Daisies, as ground cover flowers in street green space, have strong charm and can be planted with calendula, pansy, rhododendron, red leaf Berberis and so on.

Zou Ju is not only ornamental, but also often seen in some Chinese herbal medicine. It has high medicinal value, but it can not be taken casually when cultivated at home, which can only be used in medicine through professional operating procedures.

How to reproduce Zou Ju the breeding method of Zou Ju

Zou Ju is also known as horsehead orchid, longevity chrysanthemum, spring chrysanthemum, sunflower and so on. Is a kind of Compositae, perennial herb. How does Zou Ju reproduce? Let's take a look at Zou Ju's breeding method.

More information on Zou Ju's Flower language Daisy Culture methods and points for attention

Daisy is a kind of Compositae plant, synonymous longevity chrysanthemum, longevity chrysanthemum, today to share with you the flower language of Zou chrysanthemum and the breeding methods and points for attention of daisies.

The floral words of Zou Ju:

There are many daisies, the most important of which are secret love, happiness and parting. Since ancient times, people often use daisy petals to predict love. In addition, Daisy's Song is a humanistic naturalistic cosmetics developed by Shanghai Yaju Cosmetics Co., Ltd. through a deep understanding of nature. Daisies also represent purity and innocence.

Culture methods of daisies:

1. Light regulation: daisies also like sunlight, including in the growing period and flowering period. Sufficient light can promote plant growth, green leaves and increase the number of flowers.

2, temperature control: sex likes cold, cool and humid, cold-resistant but not heat-resistant, the most suitable temperature is 18-22 ℃, daisies can blossom normally, when the temperature is lower than 10 ℃, the growth is relatively slow, if the temperature is higher than 25 ℃, the flower stem will elongate, the growth potential and flowering will decline.

3. Water and fertilizer management: daisies like fertile soil and apply fertilizer every 7-10 days. Flower fertilizer of 20-10-20 and 14-0-14 can be used, or compound fertilizer can be applied or irrigated in water with a concentration of 200-250ppm. Sufficient water and fertilizer are given in the growing season to grow luxuriantly and prolong the flowering period.

4. Cultivation and management: daisies are more resistant to transplantation, which can make them have multiple roots and do not need plant shape pruning and topping to control flowering. After one or two transplants in autumn, flower beds can be directly planted in spring when they see flowers. For those who have not been transplanted by inverted border after dividing seedlings in autumn, it is appropriate to plant in the flower bed or go out of the nursery to list in spring after the border with sufficient base fertilizer is preserved and formed.

5. Diseases and insect pests: the main diseases of daisies are seedling sudden disease, gray mildew, brown spot, anthracnose, downy mildew (chlorothalonil 800 times, Jiaxianling 1000-1500 times), aphids and so on.

Points for attention in the culture of daisies:

When planting, apply rotten leaf fertilizer or stables as base fertilizer, plant spacing of 15 cm. After planting, it should be watered every 7-10 days. Do not need to fertilize too frequently, apply thin dung water every 2-3 weeks, plough once a month, and stop fertilizing after flowering in February.

During the growing period, daisies like to have plenty of sunshine and are not tolerant to shade. After the daisies are sown in autumn to promote growth, if there is no seedling transplant, the seedlings can be raised and separated at the end of October, with a little persistent soil in the root clump, and then grab-pick up the humus-rich moist and fertile soil prepared in advance.

Daisies bloom poorly in the hot summer and are easy to die. If you dig up a cool place for transplanting, you can still blossom again in autumn.
