How to raise the elixir flower after the flower, the cultivation method and precautions of the elixi

1. Soil: The soil is preferably fertile, loose and well-drained acidic sandy loam. A mixture of culture soil, peat soil and coarse sand should be used for potting with a pH of the soil.

2. Watering: Dragon boat flowers like to be wet and afraid of dryness. During the growth period of stems and leaves, sufficient water is needed to keep the potting soil moist, which is conducive to branch germination and leaf growth.

However, if it is too wet for a long time, it is easy to cause some root rots, affecting growth and flowering. If the soil is too dry or sometimes dry and sometimes wet, the water supply is not timely, and the phenomenon of falling leaves will occur.

3. Sunlight: Dragon boat flowers need to be sunny, especially in the growth period of stems and leaves, under sufficient sunlight, the leaves are green and shiny, which is conducive to the formation of inflorescences, neat flowering, and bright flower colors. It can also grow in semi-shady environments, but the leaves are pale green, lack luster, have few flowers, and have lighter flower color.

However, proper shade during strong light in summer can prolong the flowering period.

4. Temperature: The suitable temperature for the growth of dragon boat flower is 15-25, 24-30 from March to September, and 13-18 from September to March of the following year. The temperature in winter is not low 0, and it is easy to suffer from frost damage if it is too low.

On the contrary, the dragon boat flower is resistant to high temperatures and grows as usual above 32. In general, the dragon boat flower is relatively adaptable to temperature.

5. Fertilization: During the growth period, apply nitrogen, phosphorus, potassium, ferrous sulfate and horseshoe flakes once every half a month, mix with water and liquid fertilizer after decomposition and fermentation in the ratio of 1:1:1:2:3.

The elixir loves sunshine, warmness, and is not cold-tolerant, so it should be placed in sunny courtyards, roof gardens and south- and west-facing balconies. When the minimum temperature drops to 5 in winter, it should be moved indoors, placed in a sunny place in the window sill for maintenance, and the room temperature can be safely wintered by keeping the room temperature above 5, and the temperature can be left out of the room when the temperature is stable above 10 in the next spring. In addition to ground planting, elixir flowers can also be potted.

Potted elixir flowers should be selected clay pots with good permeability, such as purple sand pots and plastic pots with poor permeability and more beautiful. Tile tiles or hard plastic foam blocks can be broken in the bottom cushion of the basin floor to enhance ventilation and drainage. Potting soil requires humus-rich, loose, fertile acidic soil, with a pH value preferred.

Avoid saline-alkali soil and heavy clay. The culture soil can be prepared according to 4 parts of humus, 4 parts of sandy loam soil, and 2 parts of river sand, and appropriately mixed with some bean cake powder or sesame oil residue that has been decomposed, and a little hoof powder can also be placed at the bottom of the pot as bottom fertilizer. Potted plants are left in early April and placed in semi-shade for maintenance.

Elixir flowers like fertilizer, a small amount of nitrogen, phosphorus and potassium compound fertilizer is applied in about half a month during the growth period, and nitrogen fertilizer can not be applied alone, otherwise the branches and leaves will grow and the flowers will be few. From mid-April to early May, the second decomposed soybean cake water was topdressed, and from mid-May to the current bud, 2 3 times of nitrogen and phosphorus mixed decomposed liquid fertilizer was applied. During the flowering period, it is also necessary to apply 2-3 times of decomposed phosphorus liquid fertilizer. The potting soil should be dry and wet, and it should be watered when it is dry, and it should be stopped when it is watered.

Watering once every 4 days in spring, generally once every 1 2 days in summer, and sprinkling once a day in the morning and evening around the potted flowers to improve air humidity. In summer, it is advisable to water with soft water, and hard water is not good for the growth of elixir flowers, and the leaves are yellow, and the heavy is dead. In order to overcome the alkalinity of the soil and water quality, alum fertilizer water is poured once a week during the growing season to keep the leaves of the plants intensely green.

Proper control of the amount of water in autumn can enrich the branch tissue, and the amount of watering should be strictly controlled in winter. When watering north of the Yangtze River, it is advisable to add some ferrous sulfate (500 1) to the water to prevent long-term irrigation with alkaline water, alkalizing of the potting soil, yellowing of leaves, and death of plants. When the seedling is 15 20cm high, the top should be cut once to promote its multiple lateral branches and early plumpness.

In early winter, the plant should be pruned to retain strong branches, and cut off diseased branches, delicate branches, and overly dense branches. When pruning elixir flowers, attention should be paid to topping. When the seedlings are 15 to 20 cm high, they are topped once to promote their multiple branches and make the plant plump.

Pruning is also done several times after flowering. Every spring, when the pot is turned and the soil is changed, the overwintering old plants are left about 20 cm for a heavy pruning. Old plants need to be repotted once a year.

In winter, South China can overwinter in the open field, and other places need to be moved indoors, and the room temperature should be kept not lower than 2. Scale insects are easy to grow during the growth period, and they need to be controlled in time.

First, the breeding method.

1. Flower soil: sand soil with soft texture and good drainage is suitable for growth, and the pH value is smaller. However, in order to ensure nutrients, you can choose to add coarse sand or organic fertilizer to the peat soil, so that the preparation can meet the growth.

2. Light: Sufficient sunlight is suitable for growth, which can make the leaves green and have certain ornamental value, but the summer sun is too hot and needs to be avoided. Especially after autumn, it is necessary to increase the amount of sunlight.

If it grows in a semi-shady environment for a long time, it will cause the leaves to turn yellow and the flowers to become lighter in color.

3. Water and fertilizer: It can't withstand the arid climate, so it needs sufficient water support in the early stage of growth to keep the potting soil moist. However, if you don't water too much, it will cause the potting soil to be covered with land water, which will cause a burden on the plants and have no way to absorb it.

It is applied every half a month during the growing phase.

4. Temperature: It has strong adaptability to temperature demoulding, can withstand high temperature to 32 degrees Celsius, and the best growth temperature is 15-25.

2. Precautions.

In spring, pay attention to thinning and pruning branches to ensure good ventilation. Proper topping during the flowering period to promote the opening of the missing flowers.

In the process of cultivating elixir flowers, during the growth period, the plant can be placed in a sunny place to maintain, the temperature is controlled at about 23 32, the watering of the stem and leaf growth period should often keep the pot soil moist, and the pot soil can be kept dry when the temperature becomes low, and the organic fertilizer or inorganic compound fertilizer solution can be applied once a month in spring, summer and autumn.

1. Environmental management

Elixir flowers are more suitable for growing in a high temperature and sunny environment, not resistant to low temperature, during the usual maintenance period can be placed in a sunny place, the temperature of the control environment is about 23 32, when the temperature is lower than 20, the flowering will be reduced, at this time to extend the sunshine time appropriately, the temperature is lower than 10 to move indoors.

2. Suitable for watering

Elixir flowers like to grow in a high humidity environment, during the growth of watering should keep the potting soil often moist state is the best, in the stem and leaf growth period can be appropriately increased watering, but can not accumulate water, otherwise it will affect the growth and flowering of the plant, when the temperature gradually becomes lower, the amount of watering should also be gradually reduced.

3. Fertilization management

Fertilization management is one of the methods and precautions for the cultivation of elixir, spring, summer and autumn is the flowering period of the plant, at this time should strengthen the management of water and fertilizer, fertilization about once a month, mainly organic fertilizer or inorganic compound fertilizer, if the temperature is lower in the northern region, the fertilizer is mainly based on special flower fertilizer.

1. Soil replacement treatment

The root system of the elixir is relatively developed, and the root system can be properly repotted during the growth period to prevent the root system from rotting, at this time the soil should be re-formulated, mainly with pond mud, river sand, coconut peat mixed soil as the culture soil, the root system is disinfected and dried and then planted and watered.

2. Overwintering management

Due to the poor cold tolerance of the elixir, when the temperature is lower than 10, it will grow slowly, and the flowering will be scarce, and the minimum temperature should be controlled at about 15 for indoor potted plants, and if the temperature is too low, it will be artificially warmed, or covered with plastic film to keep warm, so as not to get frostbite.

Soil The elixir grows in fertile soil, loose and well-drained sandy soil. Potted plants can choose culture soil, peat soil, coarse sand mixed with a small amount of organic fertilizer, and the pH is controlled between .

Watering elixir flowers are resistant to moisture and driedness. Sufficient water is needed at the beginning of growth to keep the potting soil moist, which is conducive to branch germination and leaf growth. Do not overwater, the soil is waterlogged, it will cause some root rot, affecting growth and flowering.

If the water is insufficient, it will cause leaf fall.

Sunshine The growth of elixir flowers needs sufficient sunlight, especially the growth of stems and leaves, sufficient sunlight can ensure that the leaves are tender and green, which is conducive to the formation of inflorescences and neat flowering. If it grows in a semi-shady environment, the leaves are yellow, the flowers are light, and the flowers are sparse. However, in summer, it is moderately shaded by bright light.

It can prolong the flowering period.

Temperature The suitable growth temperature of the elixir is 15 25, the temperature is controlled at 24 30 in 3 September, and the temperature is 13 18 in March of the next year, and the temperature is above 0 in winter, which can be safely wintered. In short, the elixir flower is very adaptable to temperature, can withstand high temperatures above 32, and can still continue to grow.

Fertilization Fertilization once every half a month during the growth period, organic compound pants Hefei-based, supplemented by ferrous sulfate and hoof, before application, the fertilizer is mixed with water, and used after decomposition and fermentation.

During the growth period, apply 1 time every half a month with nitrogen, phosphorus, potassium, and horseshoe tablets in the ratio of 1:1:1:2:3, add water, and liquid fertilizer after decomposition and fermentation.

Pruning Pruning Now in the spring, the plants have just moved outside, and proper pruning should be carried out to ensure ventilation and light. In addition, during the flowering period, it can be appropriately plucked to promote pregnancy buds and flowering.

The soil where the elixir flower grows needs to be kept slightly acidic, and the water should be careful not to water alkaline water, and a small amount of ferrous sulfate can be applied every month.

The potted elixir in the south can be kept outdoors in winter, and in case of cold snaps, the plant can be covered with plastic film to keep warm. The northern region needs to be moved indoors for maintenance.

The main propagation method is cuttings, and the peak flowering period in summer and autumn is the most suitable time for propagation because of its rapid and lush growth. In addition to the elixir flower, the white elixir flower (Ixora parviflora) is also common, with dark green leaves, white flowers, and lanceolate flowers.

Elixir flowers prefer high temperatures, humidity and sunny environments, so it is best to plant them outdoors in a sunny place, and the soil surface of the potted plants can be watered after it is obviously dry. When the weather starts to cool down in late autumn, you can move it indoors, preferably by a window, and keep the temperature at least above 7 degrees Celsius.

Cuttings are used for propagation. It is best to carry out in June and July, take annual branches in the rainy season, cut a section of 10-15cm long, remove the basal leaves, cut the cuttings at room temperature of 24 30, and insert them in the sand bed (pot) or directly in the furrow of sandy soil. For example, before cuttings, use 0 5% indole butyric acid solution to soak the base of the cuttings for 3 5 seconds, which can shorten the rooting period, and the root system is particularly developed.

After cutting, water every day to keep the sandy soil moist, it can take root in about 30 days, and it can be transplanted or potted 10 days after rooting. Sowing and propagation: winter picking, spring sowing of the following year, germination temperature 22 24, using indoor seedling tray sowing, about 20 25 days germination.

When 3 4 pairs of true leaves grow, seedlings can be transplanted in 8 cm pots. However, the adult period is longer. In the case of many and dense branches, it can also be propagated by pressing strips, 20 cm from the top, peeling in a ring, tied with peat and film, and can heal and take root in about 2 months. Reference.

Generally speaking, after the Spring Festival, the elixir flowers wither. Usually people throw away the elixir balls that have bloomed, which is actually a pity. The elixir is a perennial plant that is propagated by bulbs, and if the flowering bulbs are buried in the soil, they can continue to grow and reproduce.

Choose a vegetable garden or nursery land with a deep soil layer and a leeward and sunny layer, build a high ridge after deep ploughing and raking, dig a ditch on the ridge, and bury the flowering bulbs in it, so that the leaves are naturally retained. After a month, the leaves wither and dormant, at this time dig up the bulb, cut off the fibrous roots, and cut off the yellowed leaves along the base, and then bury the bulb in, the depth of 10 cm is appropriate, and at the same time apply the rotten cake fertilizer or human feces, and then rake flat.

You can't try to save trouble, bury it in the pot, because the bulb has to spend a long spring, summer and autumn in the soil, especially in summer and autumn, the heat is hot, the bulb is buried in it, and there are no leaves on it, if you forget to water and fertilize them, it will cause drought and death.
