Longevity flower breeding methods and precautions: teach you how to breed

Longevity flowers are ideal for indoor cultivation in winter and spring. The plant is small and delicate, with a compact plant type, green leaves, and dense flowers. It has the meaning of longevity and longevity, and is an ideal pot flower for gifts to relatives, friends and elders. So what should we pay attention to for the cultivation of longevity flowers? Today, I will introduce the cultivation method of longevity flower.

How to grow longevity flowers (basic knowledge)

1. Soil selection for longevity flower farming

Longevity flowers cannot be cultivated with sticky soil, otherwise it will cause poor growth, rotten leaves and fallen leaves, and severely cause plant death. The pot soil should be prepared with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone meal. The culture soil is loose and fertile, has good drainage performance, shows a slightly acidic reaction, and is conducive to root development.

2. Fertilization method for longevity flower breeding

Longevity flowers cannot be cultivated with sticky soil, otherwise it will cause poor growth, rotten leaves and fallen leaves, and severely cause plant death. The pot soil should be prepared with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone meal. The culture soil is loose and fertile, has good drainage performance, shows a slightly acidic reaction, and is conducive to root development.

In the growing season, thin compound liquid fertilizer can be applied every 15-20 days to promote robust growth and lush flowering. After the flower buds were formed in November, 0.2% potassium dihydrogen phosphate or 0.5% superphosphate was added once or twice, and the flowers were more colorful, and the flowering period was longer.

3. Watering method for longevity flower breeding

Like other succulent flowers, longevity flowers contain more water in the body and are more resistant to drought, so they do not need a lot of watering. During the growth period, it is only necessary to irrigate water every 2 to 3 days to keep the pot soil slightly moist. Water control is even more important when winter temperatures are low. If you irrigate too much water, the drainage is not smooth, and the pot soil is too wet, which will easily cause root rot.

平时可每隔2~3天浇水1次。 Although the longevity flower is relatively drought-resistant, it must not be deficient in the growing season. Regarding how often the longevity flower is watered , it can be watered every 2 to 3 days. During the vegetative growth stage, the soil must be kept moist and watered at the right time. In summer, longevity flowers can be watered once a day in the evening when it is in a hot environment with strong heat, strong sunlight, large evaporation, and dry air. The winter is cold and the longevity flower enters the dormant period. Therefore, watering should be controlled or not watered for a short time.

4.Lighting requirements for longevity flower farming

Changshouhua likes to have plenty of sunshine. Family cultivation should be placed in direct sunlight all year round. In the northern summer season, the light intensity is large, and the leaf color is easy to yellow. Therefore, it should be properly shaded around noon, or placed in a semi-shade room, but pay attention to ventilation and cooling. If long-term light is inadequate, not only does the slender long-lived flower, thin and small leaves affect the beautiful plant shape, but also reduces the number of flowers, the color is not bright, and it will cause a large number of leaves to fall off and lose ornamental value.

5. Temperature requirements for longevity flower farming

The optimum temperature for longevity flower growth is 20 ~ 25 ℃. Above 30 ° C or below 10 ° C, it will obviously stop growing and enter the dormant or semi-dormant state. In winter, if the temperature is below 10 ° C, you should move into the greenhouse for winter. If possible, the indoor temperature can be controlled at 16-20 ° C during the day and 10-15 ° C at night, so that the longevity flower can bloom on the New Year's Day and the Spring Festival.

In winter, the room temperature should not be lower than 12 ° C, preferably 15 to 18 ° C during the day and 10 ° C or higher at night. If the temperature is as low as 6 ~ 8 ℃, the leaves will turn red and the flowering period will be delayed.

Topping method for longevity flower farming

At the early stage of vigorous growth, we must pay attention to topping in time to promote more branches, in order to facilitate the plump plant shape and improve the ornamental effect. After flowering, cut off the residual flowers in time to avoid consuming nutrients and affecting the next flowering quantity. Generally, the pots are changed once every spring after flowering. Pay attention to add new culture soil when changing pots.

The longevity flowers are short, compact, with green leaves, gorgeous flowers, clusters of flowers, and extremely long flowering seasons. The flowering season is the New Year and the Spring Festival. They are cultivated in small purple pots and placed on the windowsill or coffee table. Ye can enjoy flowers.

Precautions for longevity flower farming

1. Longevity flowers have phototropism, so during the growth period, attention should be paid to changing the direction of the flower pot, adjusting the light, so that the plant receives light uniformly, and promote the development of branches to all sides. If the pot is not turned for a long time, the plant will grow to one side, which will affect the ornamental effect.

2. When it is hot in summer, it should be properly shaded around noon and ensure ventilation and cooling. If you cannot receive sufficient sunlight for a long time, the branches will become weak, the flower color will be dim, the flowers will wither, and the leaves will soften and fall off, which will affect the viewing.

3. The ambient temperature should be maintained above 12 ° C. If the temperature is too low, the edges of the leaves will become red and flowering will be delayed.

4. Longevity flower is a short-day flower. The flower buds can differentiate in an environment with a temperature of 20 ℃ and 8 hours of sunshine. After the flower buds are formed, according to the demand of the plant for light, it is allowed to receive scattered light before 10am and 4pm in summer each day. Avoid strong sunlight during noon, and cover 40% of the area with a sunshade net. Light, put as much as possible under fluorescent light at night, so that summer can continue to bloom. In addition to shading in midsummer, it is necessary to maintain a light transmittance of 60 {bf} during the growing season, and to give sufficient light in other seasons.

5. Longevity flowers are usually replaced once in September to October. The pot soil is mixed with peat, vermiculite and garden soil according to 2: 2: 1. Gradually increase the light after changing pots, and start topdressing.

Longevity flower breeding method

Longevity flowers are mostly cuttings, which can also be propagated by sowing and tissue culture. Longevity flower cutting method is not complicated.

1. Cutting propagation

Longevity flowers have strong root strength, and cutting propagation is very easy to survive. The time should be from March to May in spring and August to September in late summer and early autumn. If there is a greenhouse, it can be carried out all year round. Appropriate wooden boxes can be used as cutting seedbeds, and they must be cleaned and disinfected strictly before use. The substrate can be perlite, vermiculite, peat, etc., and put into the seedbed for later use. Slightly mature fleshy stalks are selected, cut to a length of 5-6 cm, inserted into a seedbed, covered with water after watering, kept at 15-20 ° C, rooted at 15-18 days, and transplanted after one month.

2. Seeding and breeding

It is necessary to select varieties with basically the same plant type, flower pattern and flower color for artificial pollination. Seeds can be sown in spring and autumn after harvest. The seedbed can be made in a wooden box, soaked and washed with water before use, and then soaked and disinfected with 0.1 {bf} potassium permanganate for 10-15 minutes. The substrate can be 4 parts of humus soil, 4 parts of pastoral soil and 2 parts of humus soil, mixed thoroughly, piled up and matured, then excavated and sieved, and then sterilized by high temperature before use, packed into a seeding wooden box, compacted the soil Scrape the surface, spread the seeds evenly in the seedbed, cover the fine soil so that the seeds cannot be seen. After sowing, press gently on the wooden board, and place the seedbed in the water tank until the entire substrate penetrates the water .

Then cover the seedbed with a film and place it in a warm shade and airy place for seed germination. After sowing, the soil should be kept moist, water should be evenly distributed, and the seeds should not be dehydrated. The temperature of the seedbed should be controlled at about 20 ° C. Sooner or later, the film can be opened for a few minutes and then covered to allow ventilation. New shoots usually develop within 12 to 15 days. At this time, the film should be peeled off and exposed to weak sunlight. After a period of time, the light can be gradually increased. After the true leaves appear, it is irrigated with potassium dihydrogen phosphate 0.05 {bf} to promote the robust growth of the seedlings. After two or three true leaves are grown, thinning can be carried out. Seedlings sown in spring can be transplanted in summer. Seedlings sown in autumn can be transplanted before winter and placed in the greenhouse for conservation.

Conclusion: Through the above summary, everyone knows how to cultivate longevity flowers. I hope that flower friends can master the correct method to raise beautiful longevity flowers!
