。。Why are the leaves of my anthurium so small?

Anthurium does not grow? Pay attention to these 3 points, the leaves are still green and long.

Did you plant it from seeds? If so, it may be that there is not enough moisture, and the seeds have died.

Growth habit Anthurium is native to tropical rainforest areas such as Costa Rica and Colombia, and is often epiphytic on trees, sometimes epiphytic on rocks or directly on the ground, and prefers warm, humid, semi-shady environments, and avoids direct sunlight.

Temperature and light.

Anthurium is more sensitive to temperature, suitable growth temperature 14-35, optimal temperature 19-25, day and night temperature difference 3-6, that is, the best daytime 21-25, night about 19, at such a temperature, is conducive to the absorption and accumulation of nutrients in Anthurium, is extremely beneficial to growth and flowering. If it is less than 13 for a long time, the plant will not die, but it is difficult to recover growth for a long time; When the temperature is higher than 35 and the light is sufficient, the leaf surface is prone to burns, because the damaged leaves will not be reversed, which affects the overall quality of anthurium and creates difficulties for the next step of maintenance.

Under the conditions of intensive production, automatic temperature control equipment is often used for heating, and in winter, boilers are used for heating or installation of warm air heating equipment, such as oil heating machines, double-layer plastic sheets, cold-proof cloths, mats, straw, etc. Cooling often uses water curtain - fan cooling system, which is also a commonly used scheme for cooling in northern China, or water mist cooling and humidification equipment, you can also open the top window and side window of the greenhouse, and roll up the plastic sheet on the side of the plastic shed. Home maintenance, such as living in a bungalow, can be placed on the sunny side in winter, can be placed in the curtains at night, or close to the heat source, placed in the room in the shade of the window sill in summer, and pay attention to ventilation, can also be placed in the hall, or moved out of the day during the day, placed in a cool place.

Anthurium is a shade-tolerant plant and should not be exposed to direct sunlight, but do not think that Anthurium is a shade-tolerant flower and does not need light. It has been observed that when the light is increased by 1%, the flower production will also increase by 1%, but this is within the appropriate light intensity range of the anthurium. The most suitable light intensity range is 10,000-20,000 lux, mainly depending on the different growth conditions of different varieties and different growth periods, and in any case ensure that the light does not exceed 25,000-30,000 lux for a long time.

Under the conditions of intensive production, the shade often adopts a double-layer shade net, a layer of 40% fixed shade net is used outside the greenhouse, and a movable 60% shade net is erected in the greenhouse, and the light intensity is adjusted freely every day.

Home maintenance can be placed on the shady side of the room or in the hall with scattered light in summer, or in a place where direct sunlight is not visible outside, such as under the shade of trees, flowers or in the shade. In winter it should be placed on the sunny side of the room.

2.Moisture and humidity.

3.Cultivation substrates and fertilizers.

It should be caused by the lack of nutrients in the potting soil.

Cultivation needs to pay attention to the number of historical debates: 1The specifications of the pot potted anthurium from small seedlings to large seedlings at different growth stages of the pot specifications are different, the seedling stage has generally been completed in the seedling company, the anthurium seedlings we purchased are more than the seedlings, so, when planting in the pot, the choice of the pot can be planted in a red straight-edged plastic pot;

2. Cultivation substrate: The cultivation substrate must have strong water and fertilizer retention capacity, good permeability, no water accumulation, and no toxic substances, and can fix plants. Before planting, the substrate must also be thoroughly disinfected to kill pests and diseases and maintain its normal growth;

3. Anthurium is a shade-loving plant planted in a pot, and a shading net with strong shading ability is required when planting to prevent excessive light;

4. After planting, fungicide must be sprayed in time to prevent the occurrence of Phytophthora and Pythium.

Anthurium is a kind of flower that people like more, because it has a characteristic, it will grow a flower every time it grows a leaf, and if it is well maintained, the flowers can bloom very much, and the flowering period of a single flower is also very long, which is more suitable for judging and raising indoors. But a lot of flower friends raise a pot of anthurium, the early stage is very good, the later leaves grow short, the flowers also grow short, what is the reason?

The main reason for the short stem of the anthurium flower stem and the short stem and leaf is the lack of nutrients in the pot soil, and the alkaline soil is caused by it. Gardening.

Flower friends who raise a lot should know that anthurium is a flower in the south, it likes acidic soil, breeding in the north, the soil is alkaline, the water quality is alkaline, after raising for a period of time, the stem is short, and the flowers are also short, so in the process of maintaining anthurium, we must remember to regularly supplement the ratio of ferrous sulfate and ferrous sulfate to water, and water 1:1000, to water him regularly once a month, so that he can grow in the right soil, and can fully absorb iron. There will be no yellow leaves.

We also want to add sufficient nutrients to him, we cultivate anthurium, generally choose the soil with very good air permeability and water permeability, fertilizer supplementation, as far as possible to choose a fertilizer with high phosphorus and potassium content, other elements also contain, phosphorus and potassium elements can promote it to quickly grow new buds to flower, other elements are not missing, and can make it continue to grow roots, continue to grow leaves, such a fertilizer is the most suitable for him, long-term use of phosphorus and potassium fertilizer, does not contain other elements, will cause it to bloom once or twice, The late flowering can not bloom or the flowering is small, the phosphorus and potassium element content is high, and the fertilizer also contained in other town-lifting elements is guaranteed to be used 2 3 times in its growing season for a month, with a concentration of about 1:1000, so that it can have sufficient nutrients ** to ensure that it is normal to dig and grow normally.

Through our introduction, I believe you have a deeper understanding of what causes anthurium leaves to grow short, and what causes anthurium leaves to grow short.

1. The temperature is insufficient, anthurium is very sensitive to temperature, and it can withstand or exceed 15. If it is below 13 for a long time, the plant will not die with the base, but it is difficult to grow normally.

2. If the light is insufficient, the anthurium needs scattered light or a semi-shady environment, it can be placed on the window sill on the sunny side in winter, and it can be placed on the balcony on the shady side in summer.

1. Infection with diseases.

Anthurium leaves are scorched and may be infected with leaf blight, mainly on leaves. There will be spots on the leaves, and brown will appear in the middle of the spots, which will look like they are burnt.

The disease spreads rapidly, covering and depriving most of the leaves over a period of time, eventually causing the plant to die. Solution: Pay attention to prevention, strengthen ventilation management, remove diseased leaves, and then spray corresponding drugs.

Second, the fierce type of sun burn.

Causes: If the leaves are burned, it may be exposed to strong light, which will burn the leaves and cause a burning sensation. Solution: Give reasonable light during maintenance, avoid exposure to the scorching sun, and build a sunscreen to block strong light in summer. Once burned, it should be immediately moved to a cool place.

3. Air drying.

Why: Anthurium also needs a moist growing environment. If it is maintained indoors, it can also cause scorching of leaves in a hot and dry environment. Solution: When it is usually warm, open more windows for ventilation and spray some water around to improve air humidity.

Fourth, the fertilizer is too thick.

Reason: It is also possible that the fertilizer is too thick, causing the roots to be unable to absorb, resulting in root burning. Solution: Control the fertilizer at ordinary times, and dilute it with water if there is more fertilizer.

The causes and solutions are as follows:

Watering too often, anthurium likes moisture and is not tolerant to waterlogging, watering too often will make it difficult for the root system to breathe, so the leaves are yellowed.

The reason for the lack of fertilizer, anthurium likes fertilizer very much, and it should be thick, and the leaves are yellow because the environmental humidity is low, so it is necessary to keep the potting soil moist and provide plant moisture.

Pests and diseases, such as yellow code occlusion disease and leaf blight, can be sprayed with 800 times of carbendazim wettable powder for whole plants; There are red spiders and scale insects in the insect late cleft, which can be controlled with special killers, and can also be wiped with a rag and rinsed with water.

Flower candle is also called anthurium, a perennial evergreen herb of the Araceae family. short stem nodes; Leaves emerge from the base, green, leathery, entire, oblong-heart-shaped or ovate-heart-shaped. petioles elongated, Buddha flame bracts flat, leathery and waxy, orange-red or scarlet; The inflorescence of the fleshy spike is yellow and can bloom continuously all year round.
