How to raise potted flowers and Phalaenopsis? Culture methods and matters needing attention of Phalaenopsis

Phalaenopsis is an orchid family Phalaenopsis perennial herb, also known as Phalaenopsis, Taiwan Phalaenopsis, etc., is an epiphytic orchid, native to the subtropical rain forest, the plant draws long pedicels from leaf axils and flowers shaped like butterflies, deeply favored by flower fans, known as the "queen of foreign orchids". Let's take a look at the breeding methods and matters needing attention of Phalaenopsis.

Growth habits of Phalaenopsis

Phalaenopsis was born in tropical rain forest and likes warm and cold. The suitable temperature for growth is 15-20 ℃. In winter, Phalaenopsis will stop growing below 10 ℃, and it is easy to die below 5 ℃. The forest trees along the river and coast with high temperature and humidity are the places where Phalaenopsis grows. Because its physiological structure can protect itself from stress in low humidity, but in too humid environment, high temperature and high humidity are often accompanied by diseases, and the most suitable range of relative humidity is 60-80%.

Propagation methods of Phalaenopsis

1. Pedicel sprouting: the method is to cut off the flowering part of the pedicel, and then carefully cut off the bracts of the first to third internodes in the upper part of the pedicel with a blade or blade to expose the bud points in the internodes. Apply hormones such as budding agent or indolebutyric acid evenly on the exposed internodes with cotton swabs. After treatment, the orchid plant was placed in a semi-shade place, and the temperature was kept at 25: 28 ℃. After 2 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3 leaves and aerial roots. Cut off the seedlings and put them on the pot to become a new orchid plant.

2. Broken heart to promote sprouting: after the growth point of the orchid plant was destroyed due to some factors, 1 or 2 new buds will grow from the stem node near the base of the orchid plant after a period of time. This feature can be used to breed Phalaenopsis.

3. Stem-cutting propagation: the principle of stem-cutting reproduction is to destroy the growth point of stem tip to induce latent bud growth. Although there are 1-3 latent buds in the axils of Phalaenopsis plants, most of them can not sprout into plants. After the plant continues to grow upward and the stem node is longer, the upper part of the plant with roots is cut off with sterilized knives or scissors, implanted into a new basin to make it continue to grow, the lower part of the rhizome is given proper water management, and new buds can sprout soon.

4. tissue culture: Phalaenopsis can be propagated by tissue culture, which can obtain the same excellent genetic characteristics as the mother plant. The butterfly orchid seedlings produced by this method are called meristem or tissue seedlings. The plant tissues (explants) used for meristematic culture can be terminal buds (stem tips), stem segments (dormant buds), young leaves or root tips, but at present the most common is the pedicel of Phalaenopsis.

5. Sowing and reproduction

① natural sowing method: natural sowing method is to sow seeds from cracked capsules in flowerpots of parent plants. This method is simple and easy, does not need complicated aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers. However, this method has little chance of success and is rarely used.

② aseptic sowing method: the aseptic sowing method is to wash the uncracked mature capsule, then soak it in 75% ethanol or chloroform for 2 seconds, and then soak in 5% 10% bleach solution or 3% hydrogen peroxide for 5 minutes for 20 minutes. Take out the seeds and soak them in the same disinfectant for 5 minutes, then remove the solution by filtration, take out the seeds, and spread the seeds evenly on the surface of the culture medium in the prepared bottle with fine needles. The culture conditions were as follows: light intensity 2000-3000 lux, 10-18 hours a day, and the temperature was kept at 20-26 ℃. After 9-10 months, the seedlings can grow 2-3 leaves and then be planted in pots.

Culture methods of Phalaenopsis

1. Temperature: the temperature of Phalaenopsis should be guaranteed first. Phalaenopsis likes the environment of high temperature and humidity, the lowest temperature during the growth period should be above 15 ℃, and the suitable temperature for Phalaenopsis growth is 16 ℃ to 30 ℃. Attention should be paid to warming at the turn of autumn, winter and spring, as well as when the winter temperature is low.

2, humidity: air humidity: higher air humidity is better, but in family cultivation, the air humidity is difficult to adjust, so that the flowers can slowly adapt to it. At the beginning, foliar spray can be done every day, and the amount should not be too large, just soak the leaves. After that, the times of spraying were gradually reduced, and the spraying was stopped from September to October, and the spray treatment was not done any more.

3. Lighting: proper light can promote Phalaenopsis to bloom and make the flowers gorgeous and long-lasting. Generally, they should be placed indoors where there is scattered light, so as not to let the sun shine directly. After the flowering period of the butterfly orchid, the flower stem can be left 3-5 cm and the rest cut off. It can be placed in a place where the sun can not shine directly from Nanyang platform from May 1 to National Day, and near the south windowsill during the period from May 1 to May 1 to receive sufficient sunlight.

4. Ventilation: the normal growth of Phalaenopsis needs flowing fresh air, so the ventilation of domestic Phalaenopsis must be good, especially in the high humidity period in summer, it must be well ventilated to prevent heat, and at the same time, it can avoid the infection of diseases and insect pests.

5. Watering: water the flowers with tap water or Rain Water. Water thoroughly. You can often put your finger into the plant material in the pot from the bottom hole of the flowerpot. If it is wet, you do not need to water it. If the plant material at the bottom is slightly damp, water it thoroughly.

6. disease prevention: the common diseases and insect pests of Phalaenopsis are mainly soft rot, brown spot, anthrax, bituminous coal disease, virus disease, shell insects, red spiders and so on. We should mainly adopt the principle of prevention, strengthen cultivation and management measures, improve ventilation conditions, and reasonably control the placement density. keep the environment clean. Spray insecticides and fungicides regularly. If diseased plants are found, the source of infection should be cleared in time, the diseased leaves and remains should be removed, and the seriously diseased plants should be isolated or destroyed to prevent the spread of diseases and insect pests. In addition, appropriate agents can be selected for control. 60% carbendazim or 80% methyl topiramate can be used during the onset of the disease, while shell insects and red spiders can be controlled with 40% omethoate or 80% dichlorvos 1000 × 1500 times.

Matters needing attention in Phalaenopsis Culture

1. The natural flowering period of Phalaenopsis is from March to May, and the viewing period is generally more than 2 months. Many flower friends think that it is difficult to cultivate Phalaenopsis at home. In fact, if you pay attention to conservation, it can blossom completely.

2. Temperature is one of the key factors for Phalaenopsis conservation. The suitable temperature for the growth of Phalaenopsis is 18-28 ℃, but in summer, the indoor temperature is often above 30 ℃. Phalaenopsis can be kept in a ventilated semi-shaded place during maintenance, which is beneficial for it to spend the cool summer. Phalaenopsis needs low temperature to promote flower bud differentiation, generally less than 20 ℃ can achieve the purpose of promoting flowers, but the indoor temperature in winter is sometimes lower than 10 ℃, which is not conducive to the growth of Phalaenopsis. Phalaenopsis can be placed in sunny windowsill or near heating equipment to increase the temperature.

3. Phalaenopsis likes to be wet. during the growing period, the substrate should be kept moist, a little dry is beneficial to root growth, and long-term excessive humidity will lead to root rot. Indoor relative air humidity should reach more than 60%. If the weather is dry, it is necessary to spray water to moisturize the plants to form a microclimate conducive to the growth of Phalaenopsis. Conditional humidifiers are available to increase air humidity.

4. the seedling stage does not require high light and can be maintained in a semi-shady environment. Adults like sufficient scattered light. Full light can be seen in the morning and evening in spring, summer and autumn, shade at noon and all day in winter. Too strong light will burn the leaves, too weak leaves grow too long, affect the ornamental, and poor flowering.

5. After the butterfly orchid flowers, the pedicels should be cut off and the pots should be changed in time. After removing the basin, the original matrix is removed, and the rotten and withered roots are cut off, and the maintenance can be continued after being replaced with a new substrate.

What if the leaves of Phalaenopsis turn yellow?

The main results are as follows: 1. The top of the new shoot of Phalaenopsis shrinks, the young leaves are yellowish, and the old leaves are getting dark yellow. The reason is that the accumulated water is wet for a long time, which leads to the lack of oxygen in the soil and the decay of some roots, so watering should be controlled and fertilization should be stopped.

2. The new leaves of Phalaenopsis grow thick and shiny, but the leaves are uneven, and the old leaves turn yellow and fall off. This situation is caused by excessive fertilization. Should immediately stop fertilizing, appropriate more watering, sprinkle some radish or cabbage seeds into the basin, a few days after emergence, pull out, in order to consume the excess fertilizer in the basin. It is not suitable to sow seeds in winter. You can transplant a few small plants and then plant them.

3. The top and new leaves of Phalaenopsis are normal, but the lower leaves of the plant are dry and yellow at first. The reason is that Phalaenopsis is dehydrated because it has not been watered through for a long time. It should be properly watered to keep the basin soil moist up and down.

The reason why Phalaenopsis does not bloom

1. Soil reason: Phalaenopsis likes acidity, and the best pH value of soil is 4.5 to 5.5, so we should pay special attention to mastering soil pH in daily management, otherwise it will affect the absorption of water and nutrients in roots because the soil is alkaline, resulting in poor growth and non-flowering.

2. temperature reason: the suitable temperature for the growth of Phalaenopsis is 23 to 28 degrees Celsius, and only by keeping this temperature can it blossom well.

3. Lighting reasons: if the light is too weak, the growth of Phalaenopsis will be abnormal, often with more leaf buds and fewer flower buds.

4. the reason of ventilation: Phalaenopsis is easy to get sick when it is placed in a place with poor ventilation, especially at the flowering stage, the top of the flower stem is easy to wither, causing the buds to wither and yellow, affecting flowering, and even the blooming flowers are easy to decay early.

5. The reason of fertilization: excessive fertilization is easy to cause the bud of Phalaenopsis to fall early. Nitrogen fertilizer can be applied in vegetative growth period, but in reproductive growth period, nitrogen fertilizer should be stopped and more phosphorus and potassium fertilizer should be applied to promote budding and flowering.

6. watering reasons: insufficient watering can easily lead to withered and yellow leaves, affecting flower bud differentiation and flowering.

What if the butterfly orchid thanks?

1. If your Phalaenopsis is bought by yourself or given by a friend before and after the Spring Festival, it will bloom when you buy it, and there will be no flowers until now (around the end of March). If you want it to continue blooming, you can choose to keep the pedicel and check the root system.

If ① has rotten roots and dried roots cut off in time, check whether the water moss is rotten and moldy, consider whether it needs to be replaced, still use a transparent basin, normal watering maintenance, see wet and dry.

It is better for ② to have more humidity at home (it doesn't matter), and it's better if you have liquid fertilizer at home (it doesn't matter if you don't have it). If the plant is strong, it will soon continue to grow new buds at the front of the original pedicel.

If the ③ plant is weak and consumes more after blooming, it will grow lateral peduncles and buds on the original pedicel and keep blooming until the end of June. (this flowering period will be shorter because the climate is getting hot). Cut off the pedicel after the flower fade and take care of it normally.

2. If you are domesticated, you will generally begin to grow pedicels and buds (heated houses) around December of the first year, and generally bloom at the end of February and the beginning of March, and the flowering period will last until the end of May. Then the practice is the same as above, if you want to see the flowers again, keep the pedicels, maintain them normally, and quickly grow lateral peduncles, buds and blooms on the pedicels.

3. Whether purchased or domesticated, if you do not want it to continue blooming after the first flowering (so as to preserve the physical strength of the plant), cut off the pedicel in time, still need to check the root system and plant material, and then maintain it normally. By the end of the year, new stalks will sprout naturally and buds will appear frequently.

4. Many people think that Phalaenopsis is difficult to maintain because it needs a warm and humid environment. It is a blessing for Phalaenopsis to have such an environment. But Phalaenopsis is very leather and solid, and even without such an environment, it is easy to maintain it in the north.

If possible, place the ① in a place with bright light but not direct sunlight to reduce the water supply. If you feel that you don't know how to fertilize, you can always use clean water to maintain it, especially in summer, try not to apply fertilizer or apply less, and for the sake of safety after summer, you can check the root system and plant materials again to ensure the basic elements of normal plant growth.

The quality of ② management in autumn is an important factor affecting the flowering of Phalaenopsis. In autumn, you can apply thin fertilizer frequently to make the plant strong, and at this time you can appropriately increase the light. The temperature difference in the northern climate will appear sooner or later in autumn, which will prompt Phalaenopsis to give birth to flower buds. Dry in autumn and keep proper moisture. It is possible to spray water to increase the humidity of the air (it doesn't matter if you don't spray).

③ should grow new pedicels and buds slowly around the end of December in winter. During maintenance, it is forbidden to blow directly to the buds. At the same time, it is best to stop fertilization and control water to prevent buds from falling caused by improper application of fertilizer and water. If the heating in the house is too high, you can spray more water to keep the humidity.

④ usually pays attention to observe the root growth. The vital root system is the basic element to maintain plant growth. The root color is green, robust, strong, and the root tip red shows exuberant vitality. If the root of jailbreak is found, it means that there is something wrong with the planting material or maintenance and needs to be adjusted. If the root system blackened and rotted, it means that the water is too large. If some roots have symptoms of dryness, it means that there is too little water. Under normal conditions, the leaves are bright, shiny, thick and stiff, indicating that the growth is good, and new buds will continue to grow.

Phalaenopsis pictures Phalaenopsis culture methods and matters needing attention

Butterfly orchid is graceful, gorgeous in color, with the title of queen of orchid, is now a valuable variety of flowers, many people like to make it into a potted plant at home, but in the breeding process will always encounter such and such problems. In fact, if you want to raise Phalaenopsis well, you must know his breeding methods in advance, and at the same time, you must know what matters needing attention in breeding Phalaenopsis. Today, the editor specially talks about these problems for you.

Culture method

Usually, Phalaenopsis culture should choose an environment with good ventilation conditions with high temperature and high humidity. During the breeding period, we should not let the scorching sun shine directly, nor should we allow stagnant water in flowerpots, let alone let the indoor temperature be too low. Phalaenopsis is the fastest growing plant when the external temperature is between 22 and 28 degrees, and it needs different temperatures at different growth stages, especially after entering the flowering stage of Phalaenopsis. The temperature of the surrounding environment should be controlled between 19 and 21 degrees.

Matters needing attention

1. Pay attention to light adjustment

Usually, if you want to raise Phalaenopsis well, you must pay attention to the regulation of light. Many people think that Phalaenopsis is a shade-loving plant and does not need to be exposed to sunlight. In fact, this idea is wrong, especially before and after Phalaenopsis blossoms. Should be given sufficient sunlight, so that its flowers can be gorgeous and lasting.

2. Pay attention to ventilation

The cultivation of Phalaenopsis should also pay attention to ventilation and adjust the indoor humidity, especially in the hot and humid weather in summer, which can not only prevent heat, but also avoid the harm of diseases and insect pests to Phalaenopsis. In addition, when you cultivate Phalaenopsis, you should also pay attention to it is a fertilizer-loving plant. Unless the low temperature lasts, you can't stop fertilizing. Usually, you should choose the thin liquid fertilizer, and you should apply nitrogen and potash fertilizer before and after flowering.

The Culture method of Phalaenopsis points for attention in Phalaenopsis Culture

Phalaenopsis is a beautiful ornamental flower in Mei, which can be made into potted plants and placed at home, but some people can not raise Phalaenopsis well when raising Phalaenopsis. Why? For this reason, I have made a special summary on the breeding methods and matters needing attention of Phalaenopsis. Now I will write it out and share it with you. Friends who encounter problems in breeding Phalaenopsis can have a look.

Culture methods and matters needing attention of Phalaenopsis

1. Moisture requirements of Phalaenopsis.

Phalaenopsis has certain requirements for water, there can be no stagnant water in the flowerpot, otherwise it will cause rotten roots and leaves to yellowing, watering should be appropriate, abide by the principle of no dry, no watering. Phalaenopsis also has certain requirements for sunshine, can not always be placed in a cool environment, sufficient sunshine is conducive to the growth of Phalaenopsis, if placed indoors, it should be placed on the balcony every afternoon to absorb sufficient sunlight.

2. Temperature requirements of Phalaenopsis

When raising Phalaenopsis, temperature is also very important. Phalaenopsis blossoms in early spring, and people like to put it in the living room. The temperature is still relatively low this season. If the room temperature does not reach Phalaenopsis, it will not blossom or bloom late.

3. Fertilizer requirements of Phalaenopsis.

Phalaenopsis is a kind of plant that likes fertilizer, but it should be fertilized in small amounts many times, not too much at one time, which will not cause the leaves of Phalaenopsis to turn yellow and affect its beauty. In addition, Phalaenopsis culture should choose flowerpots with excellent air permeability, and try to choose large pots, which is more conducive to the growth of butterfly roots.
