The anthurium leaves and flowers are scorched, and the leaves of the anthurium are scorched

1. The first situation is that the old leaves and the new leaves, if the leaves are yellow at the same time, the main reason is because of the lack of light for a long time. Solution: Increase the lighting appropriately.

2. The second situation is that the old leaves are yellow, the main reason is that there is a long-term lack of water or watering is not watered thoroughly, which will occur. Solution: Water thoroughly every time.

3. The third situation is that if the new leaves are yellow, but the old leaves are normal, it means that the amount of watering is too large, or there is a lack of fertilizer. The solution: control watering, or top dressing.

Specific prevention measures:

First of all, cut off the yellowing leaves, put them in a cool place, and wait for the water to dry out, and then water, don't rush to fertilize. There may be two situations, one is that the air humidity is too small, that is, too dry; Another situation is the lack of trace mineral elements.

In fact, it is to control the temperature and humidity, bask in the sun in the morning and evening, and apply fertilizer appropriately.

When the anthurium leaves are yellow, dry and rotten, it may also be caused by bacteria, and the garlic juice solution, vinegar solution or carbendazim, chlorothalonil 800-1000 times liquid and other fungicides can be sprayed for prevention and control.

Indoor maintenance of anthurium should be managed in a semi-shaded, moist and warm environment, and the temperature should be between 20-25 and not higher than 33, otherwise it is easy to have uncomfortable symptoms; The air humidity must be between 75-90%, and the leaves below 50% are prone to scorched edges and dry up. You can also refer to: the solution to the yellowing and blackening of anthurium leaves.

1. There are many reasons why the tip of the anthurium leaves is scorched, if it is caused by the normal metabolism of the old leaves, the old leaves can be cut off, and the fallen old leaves can be picked up and removed in time.

2. If it is caused by strong light burning leaves, you can avoid light in summer and move to a cool place after burning.

3. If it is caused by disease, the diseased leaves can be removed, ventilation can be maintained, and pesticides can be sprayed symptomatically.

4. If the fertilization is too concentrated, the fertilization should be suspended first, and then a large amount of water should be poured to dilute it.

Cause: The leaves of Anthurium are scorched, which may be infected with leaf blight, which mainly acts on the leaves, and there will be spots on the leaves, and the middle of the lesions will appear brown and look like burnt. The disease spreads very quickly, covering most of the leaves in a period of time, eventually causing the plant to die.

Solution: Pay attention to prevention, strengthen ventilation management, remove the diseased leaves on it, and then spray the corresponding drugs.

Reason: If the leaves are a little burnt, it may be exposed to strong light, which will burn the leaves and cause a scorching feeling.

Solution: Reasonable light supply in maintenance, avoid exposure to the scorching sun, and build a sunscreen in summer to block strong sunlight. Once burned, move immediately to a cool place.

Reason: Anthurium also needs a moist growing environment, and if it is maintained indoors, it can also cause scorching leaves in a hot and dry environment.

Solution: When it is warm, open more windows to ventilate, and spray some water around to increase air humidity.

Reason: It may also be caused by too much fertilizer, which causes the roots to be unable to absorb and cause the roots to burn.

Solution: Control the fertilizer normally, and dilute it with water when the fertilizer is too much.

1. Select disease-free, robust and resistant varieties for planting;

2. Do not plant other ornamental plants in anthurium greenhouses;

3. Frequently check the health protection measures for greenhouse decay, and the work clothes of greenhouse staff should be cleaned and disinfected regularly;

4. When applying nitrogen fertilizer, avoid using ammonia, and the amount of nitrogen fertilizer should not be too much;

5. The disease is easily transmitted by water, so keep the plants dry as much as possible under the condition of maintaining suitable relative humidity;

6. Remove the susceptible plants in time, wrap them in sealed plastic bags and transport them out of the greenhouse, and carry out deep burial and virtual bridge lifting treatment;

7. Chemical control. Regularly disinfect the planting bed, and use 72% streptomycin sulfate 4000 times + new high lipid film 800 times and new phytomycin 5000 times + new high difference blue lipid film 800 times in rotation, spraying every 7 to 10 days.

Is it sunburned? This flower is afraid of the sun and dries. Spray some water mist on the leaves frequently to increase the humidity, and it will recover quickly.

Watering is too diligent, because the cultivation substrate of anthurium is generally imported peat, the ability to retain fertilizer and water is strong, but it is not easy to absorb water after drying, so it should be watered thoroughly when it is slightly wet, and it can not be watered after drying or wet, and the peat on the surface is dry as a signal for watering. If there is too much water in the substrate and watering without wetting or drying, it is easy to cause root rot and lead to poor growth of the whole plant.

Because it is difficult for anthurium to absorb general chemical fertilizers, it can only use fully water-soluble fertilizers such as 'Hua Duoduo', and the amount of fertilizer can not be too large.

Be careful not to pour tea leaves and water in the potting soil, as this will cause fatal injuries.

The maintenance environment is good for semi-shade, not all shade or all yang, but Anthurium is particularly light-loving, and it is necessary to turn the growth direction frequently to keep the plant beautiful.

The water quality must be clean, or fertilizer water, but not directly watered tap water, because chlorine and other harmful substances in tap water will cause poor growth of anthurium, or even death, to dry the water for about 2 days before watering. It is best to place it close to the anthurium so that there is no temperature difference between the water temperature and the temperature of the potting soil, and it will not harm the capillary roots of the anthurium.

1.Excessive watering: too much watering and too frequent will cause the medium in the pot to be too wet for a long time, or even accumulate water, resulting in the rot of some fibrous roots, hindering normal respiration and nutrient absorption, and causing the leaves to gradually turn yellow and fall off. Precautions: Normal watering.

2.Uneven fertilization: less fertilization, or no potting and soil change for a long time, the lack of nutrients such as nitrogen in the soil leads to thin branches and leaves, thin and yellow leaves.

In addition, excessive fertilization will also cause new leaves to be hypertrophied, uneven, and at the same time the old leaves are dry and sharp, scorched and falling off, at this time, fertilizer should be stopped immediately, watering should be increased, and part of the old soil should be removed, replaced with new culture soil, and normal management should be carried out.

3.The temperature should not be suitable: if the indoor temperature is too low in winter, the leaves will turn yellow; If the room temperature is too high, the plant will be overtranspiration, and the root water and nutrients will be insufficient, which will also make the leaves yellow. Preventive measures: Keep the temperature in the greenhouse relatively stable.

4.Soil discomfort: In most areas of the north, the medium and water contain more salt and alkali, and the leaves will gradually lose green and yellow due to the lack of soluble iron in the medium that the plants need to absorb. Preventive measures: use oxalic acid and other treatment media and watering water.

5.Dry air: When the indoor air is too dry in winter, the leaf tips are often dry and yellow, or the leaf edges are scorched, or the leaves are scorched, and the edges are curled. Preventive measures: According to the growth characteristics of anthurium, increase the humidity of the air appropriately.

6.Excessive shading: If anthurium is left in shade or in a poorly lit place for a long time, it will cause weak growth, thin and yellow leaves, and no or very little flowering. Preventive measures: According to the growth characteristics of anthurium, increase the light intensity appropriately.

7.Diseases and insect hazards: leaf spot disease caused by fungi, bacteria and other pathogens is easy to make the leaves partially necrotic and the leaves yellow; After being infected by mosaic virus, yellow-green mosaic patches will appear on the leaves; After being harmed by pests such as scale insects and red spiders, the leaves will also turn partially yellowed or the whole leaves will turn yellow and fall off.

Prevention measures: For fungal diseases, amicida, Shigao, Fuxing and other agents can be used to prevent and control them; For bacterial diseases, agricultural streptomycin and other agents can be used for prevention and control; For viral diseases, virus A, virus special and other drugs can be used; For scale insects, rapid culling and other pesticides can be used to prevent and control them; For red spiders, avermectin and other prevention and control can be used.

It is caused by excessive temperature, low humidity, and impermeable watering, so it is recommended that you improve!

Bacterial leaf blight mainly occurs on leaves and flowers, and is patchy, with irregular brown in the middle and yellow edges, and the symptoms are more obvious on rainy days. Leaf infestation usually begins at the leaf margin and in the lower part of the leaf where there are many stomata in the leaf. The initial stage of the infection is water-stained spots, and the pathogen spreads very quickly, covering most of the leaves quickly.

In a short period of time, the peduncle and leaf stem will fall off the plant, and the growth point will rot rapidly, eventually leading to the death of the entire plant. Prevention and control technology: 1

Disease-free, robust and resistant varieties were selected for planting; 2.When applying nitrogen fertilizer, avoid using ammonia, and the amount of nitrogen fertilizer should not be too much; 3..The disease is easily transmitted by water, so keep the plants as dry as possible while maintaining a suitable relative humidity; 4.

Chemical control. Regularly disinfect the planting potting soil, and use 72% streptomycin sulfate 4000 times + new high lipid film 800 times and new phytomycin 5000 times + new high lipid film 800 times in rotation, spraying every 7 to 10 days
