How to raise Anthurium andraeanum in summer? Culture techniques of Anthurium andraeanum in summer

How to raise Anthurium andraeanum in summer? I believe that many people will have some flowers and plants in their homes, which can not only beautify the environment, but also purify the hollow, and the mood will also be slightly better to see these, such as Anthurium andraeanum, which is going to be said by the editor today. The flower is beautiful. It is one of the flowers that many flower friends like. Next, the editor will talk specifically about the cultivation technology of Anthurium andraeanum in summer.

1. Moisture

Anthurium andraeanum is a variety sensitive to salt, so the substrate ph should be controlled between 5 and 6, which is the most suitable for Anthurium andraeanum growth. At the same time, tap water can also cultivate Anthurium andraeanum, but compared with tap water, natural Rain Water is also a better source of water for Anthurium andraeanum cultivation. In the process of planting Anthurium andraeanum, because the growth needs of each stage are different, and the moisture required at the development stage is also different, it is necessary to have enough moisture and maintain the dry humidity of the basin base in the seedling stage, and the seedlings grow fast in medium and large plants. in short, it is necessary to meet the various needs of Anthurium andraeanum growth stage.

II. Fertilizer

In the process of planting Anthurium andraeanum, the effect of fertilization on the root of Anthurium andraeanum is much better than that of foliar topdressing, because the leaf surface of Anthurium andraeanum has a layer of wax, which leads to the poor absorption of fertilizer. In autumn, we usually have a cycle of 3 to 4 days, and if the temperature is high, we can also apply fertilizer for 2 to 3 days, while in summer, as long as we have two days of watering and fertilization, we can only do it once a day at most. Thus it can be seen that the suitable environment is also changed because of the climatic environment. After two hours of liquid fertilization, wash out the fertilizer that remains on the leaves. In this way, you can keep the leaves clean so as not to breed bacteria.

Third, lighting

Under the influence of photosynthesis, the assimilates produced by plants will rarely warm up when the light is too strong, which will cause our leaves to change color. thus it can be seen that the success of light management directly affects the number of assimilates produced by Anthurium andraeanum and the product quality in the later stage, so it can be seen that we must use shade protection to prevent bud discoloration, of course, in different growth stages of Anthurium andraeanum. The lighting requirements are also different, which should be adjusted according to the local conditions.

4. Temperature

In hot weather, when the indoor temperature is high, the temperature can be cooled by spraying water mist in the air, and by turning on the ventilation equipment at the same time. Appropriate heating should be carried out in the cold winter to keep warm and prevent frost damage.

5. Humidity

The growth of Anthurium andraeanum needs relatively high temperature and humidity, so it is very beneficial to the growth of Anthurium andraeanum in the environment of high temperature and humidity, so the indoor humidity can be increased by spraying can.

Cultivation method of Anthurium andraeanum of flowers and matters needing attention in maintenance of Anthurium andraeanum

Anthurium andraeanum color, breeding in the indoor also purify the air and other functions, can make the indoor environment become more vibrant. If you want to raise beautiful Anthurium andraeanum at home, you need to know its breeding method in order to raise beautiful flowers. The following is to introduce the cultivation methods of flower Anthurium andraeanum.

Planting Anthurium andraeanum is commonly used for propagation, such as ramet, cutting, sowing and so on. If you want to raise Anthurium andraeanum well, you should master the technology: 1. Control room temperature. The best temperature for Anthurium andraeanum growth is 20-25 degrees, the highest should not exceed 35 degrees, and the lowest should not exceed 14 degrees. Too low temperature frostbite Anthurium andraeanum. Planting Anthurium andraeanum in summer should strengthen ventilation, spray more water and shade; planting Anthurium andraeanum in winter needs to warm up. 2. Keep the air humidity. The humidity of Anthurium andraeanum growth environment is not less than 50%, and the high humidity environment is beneficial to the growth of Anthurium andraeanum. If the temperature is below 20 degrees, you can maintain a natural room temperature environment; if the temperature is higher than 28 degrees, spray humidification should be taken to help Anthurium grow. 3. The light should not be strong. The sun shines directly and the light is too strong, which will cause the leaves to turn yellow and dry up. Anthurium andraeanum is a shade-loving plant, which is generally placed on the bright ground with scattered light indoors, and should not be placed in the position of direct sunlight. 4. Water and fertilizer should be appropriate. Anthurium andraeanum is very sensitive to salt, the less salt in the water, the better, you can choose tap water irrigation. Fertilizer can choose water-soluble chemical fertilizer, irrigated every 3 days. 5. Loosen the soil. Grow Anthurium andraeanum and choose a mixture of peat soil, leaf bran and perlite at 3:2:1. Anthurium maintenance precautions 1. Daily management of Anthurium andraeanum when Anthurium andraeanum seedlings are transplanted into pots, it is often necessary to loosen the soil in flowerpots to maintain fertility. Anthurium andraeanum is placed indoors in the sunrise but not in direct sunlight to maintain temperature and not burn Anthurium andraeanum. In addition, Anthurium andraeanum requires a lot of moisture to keep the roots and leaves moist, and you can often wipe the stems and leaves in a timely manner. In addition, it is necessary to increase fertilization according to the growth of Anthurium andraeanum and pay attention to prevent the invasion of diseases and insect pests. 2. the natural habit of Anthurium andraeanum red palm gets its name because its flower is like the palm of human hand, which belongs to the flower species of Araceae, which is native to the tropical rainforest of South America. The flower shape of Anthurium andraeanum is not large, its leaves are emerald green, the flowers are glossy like the leaves lying across, and there are many colors, mainly bright red, pink, white and so on. Anthurium andraeanum is a plant originally growing in the tropics. It likes warm, moist and sunny climatic environment. It requires high temperature and moisture, and prefers to grow in a humid and warm environment. Anthurium andraeanum is not suitable for outdoor planting because, especially in summer, the sun is too strong to burn Anthurium andraeanum, so it is generally cultivated indoors or in a flower greenhouse. Anthurium andraeanum is suitable to grow in the soil with rich, loose and good drainage. Flower Anthurium cultivation methods as above, for people who have never raised Anthurium andraeanum, they will be confused when they see this knowledge. If you do not understand after reading it, it is best to consult people who really understand flower culture. They can hand it over to you for breeding.

Propagation methods, planting techniques and matters needing attention of potted flowers Anthurium andraeanum

Anthurium andraeanum is a perennial evergreen herbaceous flower, which likes warm, hot, humid and well-drained environment. It is afraid of drought and strong light exposure. It is suitable for growth of 2632 ℃ in daytime and 213.32 ℃ at night. Can bear the highest temperature for 35 ℃, tolerable low temperature for 14 ℃, originated in South America, Europe, Asia, Africa are widely cultivated, the following editor to introduce the cultivation methods and points for attention of Anthurium andraeanum what!

Culture conditions of Anthurium andraeanum

Red palm sex likes warm, hot, humid and well-drained environment, afraid of drought and strong light exposure. The suitable day temperature and night temperature for its growth are 2632 ℃ and 2132 ℃ respectively. The highest tolerable temperature is 35 ℃ and the bearable low temperature is 14 ℃. The light intensity should be 16000-20000 lx, and the air relative humidity (RH) should be 70%-80%.

Anthurium andraeanum is native to Costa Rica, Colombia and other tropical rain forests. Often epiphytic on trees, sometimes epiphytic on rocks or growing directly on the ground, sexual preference for warm, humid, semi-shady environment, avoid direct sunlight. Native to the moist, semi-shady valleys of the tropical rain forests of South America, it is widely cultivated in Europe, Asia and Africa through introduction and improvement and greenhouse cultivation with light, temperature and water regulation systems.

Propagation methods of Anthurium andraeanum

The propagation of Anthurium andraeanum includes cutting propagation, sowing propagation, tissue culture and so on. at present, excellent plants are mainly obtained by sexual hybridization. However, because Anthurium andraeanum is a cross-pollinated plant, the offspring of hybrid seeds with high hybrid will have extensive character segregation and great variation. Therefore, asexual propagation methods such as ramet, cuttage and tissue culture are often used in production in order to obtain plants with the same characters as the mother plant.

1. Ramet propagation

Anthurium andraeanum has strong tillering ability, which can be combined with inter-seedling, seedling transfer and bud removal of cut flowers to separate the small and medium-sized lateral buds from the mother, and then cultivate the lateral buds into new plants. the specific methods should be carried out in the following aspects:

The ramet period of ① is mainly in the cool and humid spring, and it can also be ramified in the cool weather in autumn. Never split in a hot summer or in a dry and cold season.

② should pay attention to the principle of not harming the mother plant, too large lateral buds, too tight lateral buds, too weak lateral buds, mainly separate lateral buds that are easy to separate from the mother plant and are more robust, with at least two main roots or more.

When transplanting seedlings of ③, the lateral buds can be separated from the mother plants by uniform force by hand, and when it is difficult to separate, the lateral buds can be cut open at the bud eyes with a sharp disinfection blade. Cut flowers to remove buds should first be plucked from the soil layer, pay attention to the distribution of the root system and the bud eye of the underground stem, carefully cut the bud eye, and then take out the lateral bud.

The lateral buds cut by ④ were planted in a cool place after the wound was slightly dried to promote root and restore growth. When planting, the root system should be flattened, the plant should be upright, it should be supported if necessary, it can not be watered immediately after planting, it can be sprayed to the leaf surface to maintain humidity, and watering or thin fertilizer solution can be applied according to the situation after 2 days.

The disadvantages of ramet and cutting propagation are slow growth, difficult disinfection of materials and easy to carry diseases and insect pests (such as root-knot nematodes, bacteria and viruses, etc.). Ramet seedlings and tissue culture seedlings have the same technical requirements, except that the former is taller and stronger than the latter.

2. Sowing and reproduction

In Anthurium andraeanum breeding, sowing is the main way to obtain new varieties of Anthurium andraeanum. Anthurium andraeanum fruit is a kind of berry, it must be sowed with picking, peel and pulp should be removed before sowing in order to avoid rot and mildew and affect the germination rate of seeds. Sowing method can use pure sand germination method, sowing seeds in clean river sand, sowing depth of 0.5-0.8 cm, maintain a certain humidity, generally about 15 days can germinate, new leaves will soon grow. When the leaves reach 5 to 6 leaves, they can be transplanted to the substrate of pure perlite mixed with peat soil or coconut bran at 1:2 for pseudo-cultivation.

3. Tissue culture

Tissue culture is a propagation method in which plant materials are cultured in medium and new plants are obtained. the whole process is completed under aseptic conditions in the laboratory. The breeding materials must be strictly sterilized and detoxified in order to provide guarantee for the acquisition of non-toxic clone seedlings.

The propagation materials of Anthurium andraeanum are mainly callus and leaves. The reason for using callus as breeding material is that the cloned seedlings are not easy to mutate, but it is very difficult to obtain non-toxic calli. The leaves are easy to disinfect and easy to operate, but the disadvantage is that the leaves are not smooth, and the plants formed by culture are prone to mutation, but this mutation can be controlled artificially.

In the bottle seedling stage, the tissue culture seedlings completed the growth process under a variety of artificially provided optimal growth conditions. The experimental conditions are very different from the external natural conditions, so it is necessary to let the bottle seedlings go through a transitional process of strengthening and refining seedlings, so that the bottle seedlings can adapt to the external natural conditions smoothly.

[note] the culture method of Anthurium andraeanum is divided into hydroponic culture method and pot culture method according to the different culture conditions. then the editor will introduce the hydroponic culture method and pot culture method of Anthurium andraeanum.

Culture method of hydroponic Anthurium andraeanum

The blooming Anthurium andraeanum stands quietly in the water, below is the pure root system, above is the lively flower, looks makes the person feel full of joy, relaxed and happy. Among the foliage hydroponic plants, the hydroponic culture of Anthurium andraeanum is relatively difficult. The phenomenon of rotting root is easy to occur. This is related to the characteristics of Anthurium andraeanum itself. The root of Anthurium andraeanum belongs to aerial root, which is more sensitive to the ventilation of the environment. If you want to raise Anthurium andraeanum well, you must control the number of times of changing water and the capacity of filling water. The amount of dissolved oxygen in water and so on.

1. Selection of nutrient solution

It is recommended to choose foliage plant nutrient solution, which must be replaced every 7-10 days. Regularly changing the water of Anthurium andraeanum can remove the mucus and some algae secreted from the roots of Anthurium andraeanum. When the temperature is high in summer, it is more frequent to change water than in winter. It is recommended to change the water of Anthurium andraeanum every 2-3 days. The water should not be too full to prevent Anthurium andraeanum from rotting. It is best to keep about half of the roots of Anthurium andraeanum out of the water. It can ensure that the root system absorbs oxygen.

2. Light and temperature

Anthurium andraeanum likes semi-overcast, warm and humid environment is also one of the requirements of Anthurium andraeanum growth environment. It is afraid of sun exposure, so it should pay special attention to the location in the process of breeding, preferably in a place where it is ventilated and can avoid strong light. In summer, hydroponic Anthurium andraeanum should pay attention to the temperature of the surrounding environment should not be higher than 28 degrees. The relative air humidity should be maintained at 80%, and sprinkle some water on the leaves of Anthurium andraeanum when the weather is dry. The temperature of Anthurium andraeanum cultured in water in winter can not be lower than 14 degrees. When the temperature is lower than this temperature, Anthurium andraeanum is prone to frost injury. Be careful to keep it warm and warm. And control the air humidity at about 80%, and must not put Anthurium andraeanum outdoors, otherwise it is easy to cause anthurium frostbite.

3. The way of increasing oxygen

The problem faced by hydroponic Anthurium andraeanum is that it will cause rotten roots of Anthurium andraeanum if there is little dissolved oxygen in water, so it is necessary to increase the oxygen content in water in time. The easiest way is to vibrate, fix the flower plant with one hand, and gently shake the vessel with the other for more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can be increased by about 30%. Or add 1% hydrogen peroxide (3% hydrogen peroxide) to the nutrient solution, and if possible, a miniature submersible pump or aeration pump can be used to add oxygen to the nutrient solution.

[note] hydroponic Anthurium andraeanum must choose the nutrient solution suitable for the growth of Anthurium andraeanum, have suitable light and temperature and maintain it carefully. when hydroponic Anthurium andraeanum is cultured, part of the original roots can be removed and the roots can be removed slightly. If you want to enhance the aquatic adaptability of the root system, you can seriously remove the root.

Matters needing attention of hydroponic Anthurium andraeanum

1. What if the Anthurium andraeanum leaves in the water turn yellow?

Answer: it is necessary to disinfect Anthurium andraeanum. It is recommended to buy hydroponic domestication solution in flower market to promote rooting. It is safe to grow flowers with it after dilution, the water temperature should be close to room temperature, tap water should not be used directly, and yellowed leaves should be trimmed off. Generally speaking, flowers have yellow leaves. Just trim them. When the flowers have new leaves, they are healthy.

2. Hydroponic Anthurium andraeanum now that the leaves and flowers are dry to death, how to do?

A: putting too much nutrient solution will cause leaves and flowers to change water, but don't put the nutrient solution yet.

3. Often change water but hydroponically cultured Anthurium andraeanum stink, and some leaves turn yellow?

Answer: yellowing leaves can be identified as lack of nutrition. The stench of the water is caused by root rot. It is suggested to disinfect the roots and then add a special nutrient solution for hydroponics to improve it.

4. How to apply fertilizer for hydroponic Anthurium andraeanum?

Answer: hydroponic Anthurium andraeanum had better choose special liquid fertilizer of Anthurium andraeanum, because Anthurium andraeanum has a large demand for magnesium, so the general compound fertilizer is not only alkaline, but also has less magnesium content! After each change of water, drop 1-3 drops into the water, depending on the size of the container.

5. The reason for the blackening of the root of Anthurium andraeanum in hydroponic culture.

Answer: hydroponic Anthurium andraeanum should be placed in a bright place in front of the window with diffuse light. Unlike soil flowers, hydroponic flowers cannot have direct light to illuminate their roots, otherwise they will inhibit the roots or cause photooxidation injury of the roots, resulting in blackening of the roots and loss of activity due to severe decay. You need to cut off the rotten roots and let them all soak in the nutrient solution.

Culture method of potted Anthurium andraeanum

1. Selection of soil matrix.

The soil matrix for planting Anthurium andraeanum must keep good permeability and no stagnant water. When family farming, you can choose to buy prepared culture soil in the horticultural shop and add a mixture of ceramsite and dry bark (ceramsite: dry bark = 2:1) as the substrate. The substrate needs to be disinfected before planting to prevent Anthurium andraeanum from being affected by insect pests in the later stage of growth.

2. Temperature requirements for culture

The most suitable growth environment temperature of Anthurium andraeanum should be controlled between 14 and 35 degrees. In winter, when the temperature is lower than 10 degrees, it is easy to cause red frost damage. Pay attention to keeping the anthurium warm and warming. In summer, when the temperature is higher than 35 degrees, you should humidify Anthurium andraeanum and spray water around it. Do this even if it is high temperature, but if the humidity is high, Anthurium andraeanum is not easy to be hurt.

3. How to apply fertilizer correctly

Anthurium andraeanum has a higher demand for magnesium fertilizer than other foliage plants. When family farming fertilizes Anthurium andraeanum, it is recommended to buy Magic Kang fertilizer and apply it together with foliar fertilizer in the horticultural shop. Or fully water-soluble compound fertilizer such as Huaduoduo universal fertilizer is diluted to 800Mel 1000 times liquid fertilizer and applied regularly (not less than once a week). The principle of Anthurium andraeanum fertilization is to apply less thick fertilizer and frequently apply thin fertilizer.

4. Appropriate watering cycle

Water Anthurium andraeanum according to the dryness of the substrate in the basin. If the temperature is high in summer, it is recommended to water once every two days, and spray water to the leaves at noon to increase the relative humidity of the room. In winter, watering every 5-7 days is recommended. Watering in the cold season should be carried out between 9 am and 4 pm to avoid frostbite to the roots. Generally speaking, water can be watered every 3 days in spring and autumn. Avoid adding water when the plant is seriously short of water, which will affect the growth and development of Anthurium andraeanum. In the process of watering, dry and wet must be carried out alternately, do not water in the case of serious water shortage, this will affect its normal growth and development.

5. pay attention to the control of humidity

High temperature and humidity are beneficial to the growth of Anthurium andraeanum. When the indoor temperature is higher than 28 degrees, the relative humidity of the air needs to be increased. At this time, tools such as air humidifiers can be used to increase the humidity of the air. Temperature is closely related to humidity. When the indoor temperature is lower than 20 degrees, it is necessary to maintain the indoor ambient temperature and humidity. However, in winter, even if the temperature in the greenhouse is higher, it is not suitable to cool and moisturize too much, because the plant leaves are too wet at night but reduce their ability to keep out the cold, making it easy to frostbite, which is not conducive to safe overwintering.

[note] the methods of hydroponic culture and pot culture of Anthurium andraeanum are introduced here, and then the editor will introduce the pest control and breeding points for attention of Anthurium andraeanum.

Pest control of Anthurium andraeanum

1. Bacterial leaf spot

Bacterial disease is almost a fatal disease of Anthurium andraeanum. There are two symptoms of bacterial leaf spot.

① appeared on the leaves and flowers, and there were water-like spots on the back of the leaves and flowers at the early stage, and brown spots on the leaf margin at the later stage, accompanied by a yellow halo.

② was expressed on the stem, and the bacteria infected the stem at the initial stage, infected the cells through microtubule bundles and rapidly expanded to the whole plant. In the early stage of the disease, it can be found that the color of the new leaves is dull, because the microtubule bundles are blocked by bacteria, which hinders the flow of water and nutrients in the body, which makes the leaves dim and the leaves yellow. it will cause pedicels and leaves to fall off from the plant in a short time, and the growing point will rot quickly and bacterial pus will flow out. Sometimes when sap carries bacteria to the leaves, there will be water-like spots on the leaves, similar to the infection of leaves and flowers, except that these water-like spots often appear near the main vein in the middle of the leaves.

2. Anthrax

[pathogen] Alternaria or Alternaria, the symptom of the disease is to form a round brown spot along the leaf vein, and then the spot is linked together to form a large spot with a brown edge, and the disease finally dries up. The disease of Alternaria is similar to that of Alternaria, which has black necrosis on the conidium, which can cause flower rot and form black necrotic spots on the inflorescence of fleshy spike.

[prevention and treatment] ① strengthens the management of greenhouse, regularly ventilates and cleans up diseased leaves and plants in time. In the early stage of ②, 50% methyl topiramate, 80% mancozeb, 75% chlorothalonil, 50% carbendan and so on were sprayed in time. Take the medicine every 7 to 10 days, a total of 2 to 3 times.

3. Leaf spot

[pathogen] the main symptoms of Cercospora fungi are brown spots on the leaves, death of the central tissue of the spots and a circle of yellow tissue on the outside.

[control] ① adjusted the proportion of fertilizer, increased the application of phosphorus and potassium fertilizer, improved the disease resistance of plants, and found that diseased plants and diseased leaves should be destroyed or buried in time. ② drug prevention and treatment can be sprayed regularly with 50% carbendan, 75% chlorothalonil, 50% prohydantoin and 64% disinfectant alum M8, once a week for 4 to 5 times.

4. The disease of Alternaria

[pathogen] Alternaria disease is a fungal disease, the main symptoms are that the leaves gradually dry, yellowing and wilting, and the base of the plant turns brown.

[prevention and treatment] 5% Prochloraz and 50% methyl topiramate can be used.

5. Insect pests

The main pests on Anthurium andraeanum are mites, thrips, nocturnal moths, whiteflies, snails, locusts and so on. Among them, the occurrence of nocturnal moths is more serious, especially after July, and the batch occurrence is about 6-7 times a year, followed by snails. Thrips only harm some varieties, but occur in all seasons of the year, and the occurrence of mites is more serious from July to September.

Matters needing attention in culture of Anthurium andraeanum

1. Humidity control

Anthurium andraeanum in culture should pay attention to moisturizing, if you can correctly control the humidity needed during the growing period of Anthurium andraeanum, it can make Anthurium grow healthily, the petals are fiery red, extremely bright, and the posture is very beautiful.

2. Lighting control

Anthurium likes the sun. If there is not enough sunlight during the growing period, it is difficult to blossom, but it is not suitable for direct sunlight, and there will be leaf burning. The best way is to put it in a bright shady place, which can be protected from both strong and refracted sunlight.

3. The temperature is suitable

Anthurium andraeanum culture should pay attention to temperature control, its suitable temperature for growth is 18 ℃-- 28 ℃, the highest temperature should not exceed 35 ℃, the lowest temperature is 14 ℃, freezing injury may occur at any time below 10 ℃, so high temperature in summer should pay attention to ventilation and watering, and greenhouse culture should be carried out in winter.

The breeding methods and matters needing attention of Anthurium andraeanum are introduced here. Under normal circumstances, it can blossom about 150 days after planting. The florescence is mostly between summer and autumn, so we should always pay attention to watering the plants and keep the soil moist. If the weather is dry, spray water properly on the leaf surface to help it wash the dust. Lighten the burden of absorbing water from the roots. Topdressing once every 15 days or so can be soaked with peanut bran and diluted 10 times after maturity which has a significant effect on promoting flowering.
