Maintenance method of Anthurium andraeanum
Anthurium, also known as Anzu flower, flamingo taro, flamingo flower and candlestick flower.
It is a perennial evergreen herb flower of Araceae. Native to Central and South America.
Anthurium andraeanum has a short stem and is not suitable for cut flowers. It is mainly cultivated in small and medium pots. In bloom in spring, the green leaves with bright red and shining Buddha buds are very beautiful. Buddha buds can last for 50~60 days or longer, and they are excellent potted flowers. It is also a good foliage flower when it is not flowering.
It is often used to beautify the layout of family rooms, living rooms and conference rooms. Anthurium likes warm, humid and ventilated environment.
During indoor cultivation and maintenance, we should pay attention to the following points: 1. The optimum temperature for controlling the growth of Anthurium andraeanum at room temperature is 18℃-28℃, the highest temperature is not more than 35℃, and the lowest temperature is 14℃. If it is lower than 10℃, freezing injury may occur at any time. When the temperature is higher than 32℃ in summer, cooling measures should be taken, such as strengthening ventilation, sprinkling more water and shading properly.
If the indoor temperature is lower than 14℃ in winter, heating is needed. 2. Maintain high air humidity. The growth of Anthurium andraeanum needs high air humidity, generally not less than 50%. High temperature and high humidity will be more conducive to the growth of Anthurium andraeanum.
When the temperature is lower than 20℃, just keep the indoor natural environment; When the temperature reaches above 28℃, the relative humidity of leaves and indoor air can be increased by spraying, so as to create a high-temperature and high-humidity growth environment for Anthurium andraeanum. But even when the indoor temperature is high in winter, it is not appropriate to cool down and moisturize too much, because the leaves of plants are too wet at night, which will reduce the cold resistance and easily cause freezing damage.
3. Control the light. When the light is too strong, it may cause the leaves to change color, burn or scorch. The success of lighting management is directly related to the quality of potted flowers and the number of flowers.
Anthurium andraeanum is a shade-loving plant, so it should be placed indoors in a place with bright light and some scattered light. Be careful not to put Anthurium andraeanum in an environment with strong sunlight. 4. Water and fertilizer management should be appropriate. Anthurium is a salt-sensitive flower variety. The less salt in the water, the better. It is best to use tap water.
Fertilizer is often applied with water. Generally, compound fertilizer with the ratio of nitrogen, phosphorus and potassium1:1:1is selected. After the compound fertilizer is dissolved in water, it is poured with one thousandth of liquid fertilizer. Generally, water is poured once every three days in spring and autumn. If the temperature is high, water can be poured every 2 13 days according to whether the substrate in the basin is dry or wet. You can water it once every two days in summer and once when the temperature is high; Water is usually poured once every 5-7 days in winter.
Special fertilizer for Anthurium can also be used directly. 5. When changing pots, the matrix should be loose, and peat soil, leaf chaff and perlite can be mixed into mixed soil according to the ratio of 3:2: 1.
6. Family maintenance can be placed on the shady side of the room or in the hall with scattered light in summer, or out of the reach of outdoor sunlight, or in the hall, or moved out of the room during the day and placed in the shade, among flowers or in the shade. It should be placed on the sunny side of the room in winter, and it can be placed in the curtain or near the heat source at night.
Precautions for Anthurium andraeanum cultivation Attention should be paid to moisturizing Anthurium andraeanum. Its posture is beautiful. The leaves are inclined above the petiole. Viewed from the side, the plant is teacup-shaped, with fiery red petals and extremely bright colors. The key to cultivating Anthurium andraeanum is to master the humidity. If the humidity can be controlled correctly during the growth of Anthurium andraeanum, it will naturally grow vigorously, blossom and bear fruit.
The so-called humidity control is not simply to add excessive water to the cultivation substrate, but to maintain the humidity in the air environment. From spring to autumn, it is not simply to water the roots, but more importantly, to spray water on the leaves, and to spray it in the room where flowers are planted to keep the leaves hydrated enough. When the basin soil is slightly dry in winter, spray it on the leaves 2-3 times a week. If the room temperature is low at night, you can cover the whole plant with plastic film to keep it warm and humid.
In addition, the roots of Anthurium andraeanum are also wet-loving, so putting 20% water-absorbing stone or water-retaining moss in the culture soil around the roots can promote the normal growth of the roots and play a good role in the development of the whole plant. When strengthening the management of topdressing liquid fertilizer, the ratio of nitrogen, phosphorus and potassium is 3:3:7, and it is diluted 500 times every two months from April to June.
The optimum temperature for the growth of Anthurium andraeanum is 25-30℃. The minimum temperature during wintering should be at least 65438 05℃.
It is not easy for Anthurium andraeanum to bloom in insufficient light, but direct sunlight will cause leaf burns, so the most ideal measure is to put it in a cool place. Put it in the center of a warm and bright room in winter and avoid direct sunlight in summer. If it is sunny, it can be placed under the shade of evergreen trees or hung under a shed without strong light to avoid the burning of strong light and the refraction of sunlight.
Proper management of water, fertilizer and light can promote the healthy growth of Anthurium andraeanum leaves and produce satisfactory flowers. After the flowers that sow and propagate Anthurium are opened, white pollen is scattered. At this time, artificial pollination with dry brush can promote fertilization and fruiting.
When the seeds are fully mature, the seeds with the size of sesame seeds are picked and sown, and the suitable sowing period is May-September. Before sowing, wash the seeds with clear water to make them absorb enough water before sowing. First, put 1/2 peat soil into the sowing basin, cover it with a layer of powdery broken moss with a thickness of about 1cm, then put the wet seeds on it, and lightly sprinkle 5- 10 mm moss powder with a fine sieve.
After sowing, put the flowerpot in the shade, avoid direct sunlight, and keep the temperature to facilitate germination and emergence. Disease control 1. Symptoms of stem rot: generally, it is easy to occur when the environmental conditions of cultivation substrates deteriorate, such as excessive dryness, excessive humidity, excessive cooling, abnormal EC value and PH value. And most of them start from the bottom root system, and a few root systems are infected and rotted until the stem base turns brown and rotted, and then the leaf edge begins to turn yellow or droop, which is collectively called stem rot.
Stem rot can be caused by lower fungi, such as Phytophthora and Pythium, or by higher fungi, such as Fusarium, Cladosporium and Rhizoctonia. There are some differences in specific causes and symptoms, but it is generally difficult to distinguish. Prevention and control measures: When the environmental conditions are not suitable for plant growth or some environmental factors have extreme changes (including the initial stage of the disease), broad-spectrum fungicides can be used for prevention and control, such as using some lower fungi fungicides and some higher fungi fungicides alternately, watering the roots around the plants with 5000 times Lu Shuang solution, or watering with 800 times 70% thiophanate-methyl.
What are the breeding methods and precautions of Anthurium andraeanum?
Cultivation methods and matters needing attention of Anthurium andraeanum.
The following aspects should be paid attention to in family seedling raising of Anzuhua: 1 and humidity. The normal growth of Anthurium andraeanum needs about 70% air humidity, which is generally difficult to achieve in ordinary family farming. You can wipe the leaves with a clean wet towel several times a day, or spray water around the plants regularly to increase the air humidity. But don't sprinkle water on the flowers, so as not to affect the ornamental quality. )
See big picture 2. Under the normal growth conditions of watering and fertilization, we can see the dry and wet land watering the cultivated soil every week. Generally master the principle of not watering the soil surface and pouring it thoroughly.
In spring, autumn and winter, the number and quantity of watering can be appropriately reduced. Apply 7-8% special nutrient solution or 500 times diluted fat water with water every half month.
3. Pruning Under normal circumstances, during the growth of Anthurium andraeanum, the petiole at the base gradually degenerates, and the stipules can be cut off in time when they are dry. When the pedicel becomes Huang Shi after flowering, it should also be cut off from the protective column with 2 cm at the base as soon as possible.
Look at the big picture. 4. temperature. The temperature of Anthurium andraeanum should be guaranteed as much as possible. The optimum growth temperature of Anthurium andraeanum is 16-24℃, and the lowest temperature should be above 12℃. If ordinary families have heating facilities, this condition is easy to achieve.
But at the same time, we must be careful not to put the flowerpot on the radiator or get too close to it. When the temperature exceeds 30℃ in summer, flowers and plants should be moved to a room relatively north of the ventilated place, and water should be sprayed around the plants to cool down.
5. The normal growth of Anthurium andraeanum needs enough scattered light. Generally speaking, family farming should pay attention to: avoid direct sunlight on leaves and flowers in summer; In autumn and winter, if possible, move to the window to increase the light. It is also necessary to rotate plants regularly to ensure that they receive uniform light and promote their crown shape.
At the end of the big picture, Meilele Decoration Network also needs to remind everyone that to learn the cultivation methods and precautions of Anthurium andraeanum and master the growth and cultivation substrate of Anthurium andraeanum, the cultivation substrate must have strong water and fertilizer retention ability, good air permeability, no water accumulation, no toxic substances and the ability to fix plants. You also need to pay attention to the humidity and moisture of the air, as well as the temperature. Otherwise, there will be the phenomenon of Anthurium rotting leaves.
What are the breeding methods and precautions of Anthurium andraeanum?
Anthurium andraeanum is a perennial herb of Anthurium in Araceae.
Also known as candles, Anzu flowers and flamingo flowers. A tropical rain forest native to South America.
Sex likes warm and humid semi-cloudy environment, not cold-resistant, fat-loving, and salt-alkali avoidance. Anthurium andraeanum is a rare flower with unique flower pattern, Buddha bud and bright color.
Its flowering period is very long, lasting 4~6 months. The cultivation and management of Anthurium andraeanum should start from the following aspects: (1) substrate.
Must have strong water and fertilizer conservation ability, good permeability, no water accumulation, no toxic substances, and can fix plants. Before planting, the substrate must be thoroughly disinfected to kill pests and diseases and maintain the normal growth of plants.
A mixed matrix of peat, perlite and sand can be used. (2) Water management.
Anthurium andraeanum is a salt-sensitive variety, and the pH value of the substrate should be controlled between 5.2 and 6.2 as far as possible, and the optimum pH value for Anthurium andraeanum growth is 5.7. The EC value suitable for Anthurium andraeanum growth is 1.2.
High EC value will lead to smaller flowers and shorter stems, thus reducing the ornamental value. Natural rain is the best water source for Anthurium andraeanum cultivation.
Potted Anthurium andraeanum has different water requirements at different growth and development stages. At seedling stage, because the root system of plants is weak, it is shallowly distributed in the substrate and is not drought-tolerant. After planting, spray water 2~3 times a day, and often keep the substrate moist to make it grow early, take more new roots, and pay attention to the dryness and humidity of the substrate on the surface of the basin. In the middle and large seedling stage, plants grow fast and need more water, so water supply must be sufficient; Appropriate watering should be reduced at flowering stage, and more phosphorus and potassium fertilizer should be applied to promote flowering.
(3) Moisture and humidity control. The key to the success of cultivating Anthurium andraeanum is to maintain a relatively high air humidity. Especially in the high temperature season, the relative humidity of the air in the greenhouse can be increased by spraying system and atomizing system (be careful not to spray the leaves at night, and ensure that there is no water drop on the leaves of Anthurium andraeanum at night) to avoid burning the leaves at high temperature, resulting in scorching, abnormal buds and fading.
In the process of watering, master the alternation of dry and wet, and never water plants when they are seriously short of water, which will affect the normal growth and development of plants. In high temperature season, it is usually watered once every 2~3 days, and water is sprayed on the leaves at noon to increase the indoor relative humidity.
In cold season, watering should be carried out before 9: 00 a.m. to 4: 00 p.m. to avoid root frostbite. (4) Temperature adjustment.
The optimum growth temperature is 20~30℃, the highest temperature should not exceed 35℃, and the lowest temperature should not be lower than 14℃, otherwise it may cause freezing injury. (5) lighting.
The optimum light intensity is 10000 lux and should not be higher than 30000 lux. Anthurium andraeanum is not resistant to strong light, so it should be cultivated in suitable shade environment all year round.
Especially in summer, you need 70% shading. Direct sunlight will make the blade temperature higher than the air temperature. If the leaf temperature is too high, it will burn and scorch the leaves, wither the buds and slow the growth of the leaves.
How to maintain Anthurium?
(1) Cultivation method When potted seedlings, according to the process, the cultivation substrate should be prepared first, and the substrate with good permeability should be selected. Plant ash and perlite are commonly used in China (the ratio is 3: 1), and the culture medium still needs disinfection.
If you use an old pot when serving, the pot should also be disinfected to avoid cross-infection between germs and eggs. Pots can be cultured in black plastic bags or directly placed in plastic pots.
But no matter what basin you use, you should choose one with good drainage performance. If the eye of the basin is blocked, clear it before serving.
Its planting requirements are the same as those of low planting, that is, neither deep nor shallow, and the stem tip has no medium and no sundries. (2) How to fertilize for family maintenance It is complicated to prepare nutrient solution for family maintenance.
Therefore, there are powders prepared according to the elements of nutritional needs in the market, which can be used in proportion to water when used. There is also a slow-release fertilizer on the market.
Buried in the soil according to the instructions, it will be dissolved in water later for the candle to absorb. A single application of 1-3g can make the fertilizer efficiency as long as 3 months.
These fertilizers have one thing in common: all the necessary nutrients. Different growth stages, different formulations, clean and hygienic.
In fact, slow-release fertilizers are also used for large-scale planting. Especially outdoor maintenance, fertilization is equal to white application, which can be avoided if slow-release fertilizer is used.
In family maintenance, you can also use hoof nail pieces and sesame sauce residue to rett. It would be better to add some ferrous sulfate to make the so-called alum fertilizer water. In family fertilization, we should grasp that the concentration is not thin or thick, and a small amount is repeated.
(3) How to apply water Anthurium likes the environment with high humidity. The humidity mentioned here refers to the relative humidity in the air, not just the water content in the planting medium.
Humidity is a variable, because when the humidity increases and the dry wind increases (especially in northern China), the humidity will decrease if water is not replenished. Generally speaking, the humidity required by Anthurium andraeanum should be kept at 70%-80% (the temperature is 20-28℃), and the humidity can adjust the humidity of Anthurium andraeanum, that is to say, adjust the transpiration of Anthurium andraeanum leaves.
The relative humidity is too low, which leads to drought and water shortage, dry leaves and spathe edges, and uneven spathe. The water temperature of Anthurium andraeanum should be kept at about 65438 05℃ (including nutrient solution), which is especially important in severe cold and hot summer.
The water in the culture medium should not be too wet, because the roots of Anthurium andraeanum are semi-fleshy, and a lot of water is stored in the roots. Too much water in the culture medium leads to hypoxia in the culture medium and the root respiration is blocked. If it is excessively wet for a long time, it will lead to root rot. The above is the quantitative standard to explain moisture.
It is difficult for families to maintain Anthurium in the greenhouse, which is also an obstacle for families to buy Anthurium. But we can create a humidity environment suitable for the growth of Anthurium andraeanum by the following methods.
For example, families also have ornamental fish. You can put Anthurium on the aquarium, and put the tray under the basin or next to the aquarium. You can also use two flowerpot trays, put a slightly larger tray below to hold water, and use a small tray above to buckle on the tray holding water, and then put the potted flowers of Anthurium on it, taking care that the pots don't touch water.
You can also use discarded coke bottles and mineral water bottles to fill tap water, air them for 3-4 days, then pour them into a watering can and spray Anthurium leaves. Spray it in summer 1 0: 00-1:001time, and spray it once after 15:00, but the pH value of the sprayed water should be small.
The poured water should also be dried before use. On the one hand, chlorine in tap water can be volatilized, on the other hand, the dried water can be kept consistent with room temperature. Don't dry the water in the sun to avoid the formation of green algae.
It is also feasible to use cold boiled water.
Cultivation methods and matters needing attention of Anthurium andraeanum
Anthurium likes cold and warm, wet and dry, and avoids the sun.
Flowers of perennial evergreen herbs. Sexually prefer a warm, humid and well-drained environment, and are afraid of drought and strong light. The suitable daily temperature is 26~32℃ and the night temperature is 2 1~32℃. The maximum tolerance temperature is 35℃ and the maximum tolerance low temperature is 65438 04℃. Cultivation techniques: ① Peat soil with 1/4 perlite and a small amount of bone powder or decomposed cake fertilizer powder should be selected for potted plants. The bottom of the basin should be padded with coarse sand to facilitate drainage.
Anthurium plants
(2) The growing season should be fully watered, and the basin soil should be wet and clear; In late autumn and early spring, the amount of watering should be properly controlled, and the basin soil should not accumulate water. Compound liquid fertilizer should be applied 2~3 times a month. ③ Pay attention to shading around noon in summer, and see more sunshine in the morning and evening; There should be plenty of light in winter. ④ The suitable temperature for growing period is 20 ~ 25℃, and the wintering room temperature is not lower than 65438 06℃. In high temperature season, water should be sprayed on the blades and the ground 2~3 times a day to cool and humidify. ⑤ Every 1~2 years, you need to change pots 1 time in early spring. When changing pots, the old and dead roots should be cut off, and base fertilizer and new culture soil should be added. Try not to use high ammonium nitrogen fertilizer in plant growth. Remove or isolate diseased plants. To choose strong seedlings, disinfect the cultivation medium.

Finally, Meilele Decoration Network also needs to remind everyone that to learn the cultivation methods and precautions of Anthurium andraeanum and master the growth and cultivation substrate of Anthurium andraeanum, the cultivation substrate must have strong water and fertilizer retention ability, good air permeability, no water accumulation, no toxic substances and the ability to fix plants. You also need to pay attention to the humidity and moisture of the air, as well as the temperature. Otherwise, there will be the phenomenon of Anthurium rotting leaves.
Breeding method of Anthurium andraeanum
Anthurium andraeanum is a tropical flower, which prefers yin to yang, dampness to drought, and high temperature to cold. During home maintenance, according to its habits, attention should be paid not to expose to the sun, but it should not be kept indoors in dark light for a long time. It should be placed in a place where light is scattered, and see some sunshine in the morning and evening.
Generally, the substrate for cultivating Anthurium andraeanum is peat, which is loose and breathable. If the temperature is suitable, the soil in the basin should be kept moist, or some water should be sprayed on the leaves frequently to increase the air humidity. It's getting cold now. If the temperature in winter cannot be above 12 degrees, watering should be controlled to improve the cold resistance of Anthurium andraeanum, and the lowest temperature should not be lower than 8 degrees, otherwise it will be easy to get cold.
Anthurium likes warm, humid and ventilated environment. Pay attention to the following points during cultivation and maintenance: 1, and control the temperature.
The optimum temperature for the growth of Anthurium andraeanum is 18℃-28℃, the highest temperature is no more than 35℃, and the lowest temperature is 14℃. If it is lower than 10℃, freezing injury may occur at any time. When the temperature is higher than 32℃ in summer, cooling measures should be taken, such as strengthening ventilation, sprinkling more water and shading properly.
If the indoor temperature is lower than 14℃ in winter, heating is needed. 2. Maintain a relatively high air humidity (70-80%), which is the key to indoor maintenance and is also conducive to flowering.
Methods such as foliar spraying can be used, but care must be taken to ensure that the foliage is dry at night. 3. control the lights.
When the light is too strong, it may cause the leaves to change color, burn or scorch. The success of lighting management is directly related to the quality of potted flowers and the number of flowers.
Anthurium andraeanum is a shade-loving plant, so it should be placed indoors in a place with bright light and some scattered light. Be careful not to put Anthurium andraeanum in an environment with strong sunlight. 4. Adequate fertilizer and water supply.
If the supply of fertilizer and water is insufficient, the surrounding leaves will often wither and new leaves will not grow well. Therefore, after mastering the temperature and humidity, we should pay attention to fertilization, especially in the growing period, applying more liquid fertilizer and watering: watering once every two days in summer and watering once when the temperature is high; Generally, water is poured every three days in spring and autumn. If the temperature is high, water can be poured every 2-3 days according to whether the substrate in the basin is dry or wet. Water is usually poured once every 5-7 days in winter.
What are the breeding methods and precautions of Anthurium andraeanum?
Anthurium is deeply loved by many friends because of its bright red and beautiful appearance. Many friends will keep several pots at home. Anthurium andraeanum was first discovered in South America, produced in tropical areas and cultivated all over the world. Anthurium is not.
Lighting is very popular in China, as well as in Asia and Europe. Anthurium also has a good meaning, which is a grand exhibition. Let me share with you the breeding methods and precautions of Anthurium andraeanum.
Methods/steps
Of course, the breeding of Anthurium andraeanum must start with the purchase of Anthurium andraeanum, which should be purchased in the regular flower and bird market. When buying Anthurium andraeanum, you should buy Anthurium andraeanum with bright colors and developed roots. Only Anthurium andraeanum with good quality can facilitate future breeding.
The breeding soil of Anthurium andraeanum is very important, so to choose fertile soil, you can infiltrate some sand, peat soil and so on. And these can be directly purchased in the flower and bird market to raise the formula soil of Anthurium;
You need to buy a beautiful flowerpot after choosing the breeding soil. This mainly depends on personal preference, you can choose ceramic or plastic flowerpots.
Anthurium likes cool environment and needs to keep a certain humidity. When the weather is dry, you need to water it properly, but it should not be too frequent, which is easy to cause root rot.
The living environment of Anthurium andraeanum should maintain a certain humidity. If you want to make Anthurium andraeanum grow greener, you need proper fertilization and try to apply less fertilizer in winter.
After Anthurium andraeanum grows for a period of time, there will be some rotten leaves at the bottom, which need to be pruned in time to avoid affecting the normal growth of Anthurium andraeanum.
Note: Anthurium likes wet environment. Don't be exposed to the sun for a long time. It should not be too tight for the cultivated soil. You can plant a layer of moss on the cultivated soil, which is beneficial to moisture retention.
Breeding method of Anthurium andraeanum
To raise Anthurium, a family must do the following four things. 1, selection of culture medium. The matrix used in standardized large-scale production is mainly peat soil with a small amount of perlite and coarse river sand, and a small amount of flower arrangement mud is used to cushion the basin bottom. For families, it is also quite ideal to buy the prepared culture soil in the garden store and mix it with ceramsite or dried bark (ratio 2: 1) for matrix trading. The prepared matrix must be disinfected. 2. Cultivation environment requirements. Anthurium andraeanum is a semi-shade plant, and its growth temperature is between 14℃-35℃. When the temperature is lower than 10℃, it will cause chilling injury. When the temperature is higher than 35℃, plants will also be hurt. In this case, it is necessary to spray water on the plants and their surroundings in time. To a certain extent, when the humidity is high at high temperature, it will not be so easy to cause injuries. 3. Fertilizer and water management. The demand for "magnesium fertilizer" of Anthurium andraeanum plants is usually higher than that of other foliage plants, so it is suggested to apply P: N: K =1:1:1. Ordinary families can buy15-15-15 (Molikang) granular slow-release fertilizer and apply it together with foliar fertilizer, or buy Baolifeng No.2 and dilute it to 800-1000 times liquid fertilizer for regular application. The purpose of fertilization for Anthurium andraeanum is to eat less rather than more, otherwise it will easily cause root damage, affect plant growth and directly cause plant death. Anthurium likes humidity (high relative humidity), but the substrate is dry, so it is best to spray water with liquid fertilizer, and spray water on leaves and surrounding areas at ordinary times to increase the relative temperature of the cultivation environment. 4. Prevention and control of pests and diseases. The most common pests of Anthurium andraeanum include red spider, nematode, Pieris rapae, whitefly, thrips, snails and scale insects, especially red spider, nematode and Pieris rapae. Anthurium andraeanum is very sensitive to pesticides, and the concentration must be correct when it is used. The concentration is usually lower than that used by other flowers. Pay special attention to copper-containing pesticides, dimethoate, methamidophos, dichlorvos, malathion and parathion, which are all toxic to Anthurium andraeanum.
1. Yellow leaf phenomenon: low temperature leads to rotten roots.
Too much fertilizer and water, because too much fertilization hinders the metabolism of candles.
Too much watering will also make the leaves of candles turn yellow, which will affect the viewing.
Excessive care will make the leaves of candles yellow and lose luster, grow slowly, and the leaves are short, small and curly.
2. The reason for vigorous growth but not flowering is generally that the place is too dark and there is too much nitrogen fertilizer.
Candles like temperature, but when the temperature exceeds 30 degrees, it will also inhibit growth. The lowest room temperature in winter should be above 10 degree, otherwise it will be vulnerable to freezing injury.
The cultivated soil is well-ventilated forest humus soil with high humus quality, mixed with a small amount of coarse sand and sheep manure. Because the fleshy roots of candles contain a lot of water, when planting, flowerpots should be covered with several layers of large and firm non-perishable bark or big stones as drainage layers.
It is best to water it with rain (
Cultivation methods and precautions of Anthurium andraeanum!
Anthurium andraeanum is a perennial evergreen herb of Anthurium in Araceae. This is a typical semi-fleshy fibrous root system, aerial root.
Stems are extremely short and almost stemless. Flowers can bloom all year round. Generally, when plants grow to a certain period, each leaf axil can bud and blossom.
Cultivation methods and precautions of Anthurium andraeanum: 1. Humidity The normal growth of Anthurium andraeanum needs about 70% air humidity, which is difficult to achieve in general family farming. You can wipe the leaves several times a day with a clean wet towel, or spray water around the plants regularly to increase the air humidity. But don't sprinkle water on the flowers, so as not to affect the ornamental quality. )
Secondly, under the normal growth of watering and fertilization, we can see dry wetlands watering cultivated soil every week. Generally grasp the principle of not watering the soil surface and pouring it thoroughly.
In spring, autumn and winter, the number and quantity of watering can be appropriately reduced. Apply 7-8% special nutrient solution or 500 times diluted fat water with water every half month.
Third, pruning Under normal circumstances, during the growth of Anthurium andraeanum, the petiole at the base gradually degenerates, and the stipules can be cut off in time when they are dry. When the pedicel becomes Huang Shi after flowering, it should also be cut off from the protective column with 2 cm at the base as soon as possible.
Fourth, the temperature of family breeding Anthurium should be guaranteed as much as possible. The optimum growth temperature of Anthurium andraeanum is 16-24℃, and the lowest temperature should be above 12℃. If ordinary families have heating facilities, this condition is easy to achieve.
But at the same time, we must be careful not to put the flowerpot on the radiator or get too close to it. When the temperature exceeds 30℃ in summer, flowers and plants should be moved to a room relatively north of the ventilated place, and water should be sprayed around the plants to cool down.
5. The normal growth of Anthurium andraeanum must be fully dispersed. Generally speaking, family farming should pay attention to: avoid direct sunlight on leaves and flowers in summer; In autumn and winter, if possible, move to the window to increase the light. It is also necessary to rotate plants regularly to ensure that they receive uniform light and promote their crown shape.
In addition to the above conditions, learn the cultivation methods and precautions of Anthurium andraeanum, and also know the cultivation substrate suitable for the growth of Anthurium andraeanum. The cultivation substrate must have the properties of strong water and fertilizer retention, good permeability, no water accumulation, no toxic substances and the ability to fix plants. Before planting, the substrate must be thoroughly disinfected to kill pests and diseases and maintain its normal growth.
Many friends will find that despite careful care, Anthurium will still have many problems. It is common that Anthurium leaves rot easily. How to deal with the rotten leaves of Anthurium andraeanum? Generally speaking, the causes of rotten leaves of Anthurium andraeanum are too high humidity, too high temperature and no ventilation, which is easy to cause bacterial damage, mostly fungal infection.
