How to maintain indoor Anthurium andrographis

How to raise flamingos? A skill that teaches you to improve the flamingos.

For propagation of Anthurium andraeanum, the temperature should be 19 to 25 degrees; watering should be timely; choose loose and breathable soil and place it in a place illuminated by scattered light; fertilize every five to ten days during the growth period. In addition, it is necessary to control diseases and insect pests and spray drugs in a timely manner before they occur. Then replace the basin, basin and soil should be replaced, and water should be poured after replacement.

1. Cultural environment

(1) temperature: warm, preferably between 19 and 25 degrees. Do not fall below 13 degrees in winter and not too high in summer, no more than 32 degrees.

(2) watering: it should be watered in time. Spring and summer are once or twice a day; autumn and winter are about once a week, depending on the temperature and humidity of the nine days. Spraying water in summer increases humidity.

(3) soil: the main requirement is loose ventilation. Specifically, it can be mixed with humus soil, pond mud, river sand and grass ash. You can also add some base fertilizer.

(4) Lighting: there is demand, but not much. It can be placed in a place where scattered light shines. When the light is strong, the shadow is about 70%. In winter, place it where you can touch the sun.

(5) fertilization: the growth period is about 5 to 10 days. The time is morning or evening.

two。 Prevention and control of diseases and insect pests

These diseases include anthrax and root rot. After discovery, it is necessary to cut off the damaged leaves and branches in time, and it is better to burn them. Then, you can spray chlorothalonil and so on. Pests are also common, such as snails, mites and so on. Snails are usually small in number and can be caught manually. The number of mites that can be sprayed. Both diseases and worms can be prevented before the disease occurs, and fungicides are sprayed once a month.

3. Change the basin.

After the plant grows for a period of time, the original pot can not meet the requirements, and there are not many nutrients in the soil, so the pot needs to be replaced. After replacing the new basin and soil, pour in the water. After a week, water is usually poured. No fertilizer for a month.

How to raise andrographis indoors?

First, introduce Anthurium andraeanum.

An Zuhua, also known as an Zuhua, Red Crane, Firebird, Candlestick. It is the perennial evergreen flower of Araceae. Native to Central and South America. Anthurium andraeanum has short stems and should not be used as cut flowers, but mainly for small and medium-sized pots. When spring blossoms, green leaves match bright red and shining flames. It's very beautiful. The flame can last 50 to 60 days or more. This is an excellent potted flower; when it is not blooming, it is a good flower. It is usually used for landscaping of family rooms, living rooms and conference rooms.

Second, the environmental requirements of Anthurium andraeanum growth.

1. Soil

Anthurium andraeanum is more like a wet and humid environment. The culture medium must retain water, strong fertilizer and good permeability.

2, lighting

Anthurium andraeanum should grow normally under sufficient scattered light. In summer, avoid direct sunlight and leaves; if conditions permit, move flowers and autumn near the window to increase the light. Plants must also be rotated regularly to ensure that they receive light and promote their crowns.

3. Temperature

The better growth temperature of Anthurium andraeanum is 16-24 °C, and the lower temperature should be higher than 12 °C. Please note that the pot should not be placed on or too close to the radiator. When the summer temperature exceeds 30 °C, the flowers and plants should be moved to the room in the north ventilated position and water should be sprayed around the plants to cool.

4. Humidity

The normal growth of Anthurium andraeanum needs about 70% air humidity. You can use a clean wet towel to wipe the leaves several times a day, or spray water around the plant regularly to increase air humidity. (but do not sprinkle water on the flowers, so as not to affect the quality of viewing. )

Third, the method of watering flowers.

The watering of Anthurium andraeanum is based on the dryness of the soil. We must go every three days in spring and autumn. In summer, every two days, and pay attention to summer, use a sprayer to spray leaves at noon to increase humidity. In winter, you can pour water every 5-7 days. When the weather is cold, it is watered between 9 a.m. and 16:00 When watering, we should pay attention to the alternation of dry and wet, avoid watering in the case of serious lack of water, affecting the growth and development of Anthurium andraeanum.

Fourth, the fertilization method of Anthurium andraeanum.

The normal growth of Anthurium andraeanum requires many nutrients, including large amounts of elements such as nitrogen, phosphorus and potassium, as well as trace elements such as iron, copper, manganese and zinc. However, the surface of Anthurium andraeanum leaves is waxy and does not absorb nutrients. Therefore, root fertilization should follow the principle of "thin fertilization". When fertilizing, it should be noted that the amount of nitrogen fertilizer should be increased in the plant growing season; in late autumn and early winter, phosphate and potassium fertilizer should be added to help plants resist the cold; in winter, fertilizer should be controlled, water source should be controlled, and winter should be safe. In addition, immediately after applying liquid fertilizer, spray the leaves of the plant, wash the leaves, and avoid burning the leaves.

Fifth, the pruning method of Anzu flower.

Under normal circumstances, during the growth of Anthurium andraeanum, the petiole at the base is gradually degraded, and the stipules can be removed in time during drying. When the peduncle turns yellow, it must be removed 2 cm from the bottom of the guardrail as soon as possible.

6. Pest control of Anthurium andraeanum

These diseases mainly include leaf spot, anthracnose and root rot, while the common pests of Anthurium andraeanum are red spiders and aphids. Mainly through the control of temperature, regulation of moisture, prevention of drugs. The most important thing is to observe, prevent and remove pests and leaves in time.

Seventh, the choice of Anthurium andraeanum flowerpot

Anthurium andraeanum is a kind of fleshy root sensitive to light, so it is usually necessary to choose flowerpots with low light transmittance and a large number of vents at the bottom. Therefore, peat pots, black plastic pots and so on are better. However, it is better not to choose plastic pots at night, it is better not to use glass pots.

Eight, Anthurium andraeanum hydroponics

1. Transplant

Dig the potted Anthurium andraeanum from the soil, cut off the rotten roots, hairy roots and old leaves, wash the roots with water, disinfect them with potassium permanganate solution, and then rinse Anthurium andraeanum with water. If you use transparent glassware to grow Anthurium andraeanum, it is better to cover the glass with a black plastic bag to prevent glare. The top is covered with a transparent convenient bag (heat preservation and moisturizing). Place it in a place where the scattered light is kept at 10 degrees or higher.

2, change the water

The root of Anthurium andraeanum is very strong. It is necessary to change the moisture of Anthurium andraeanum regularly, remove the mucus secreted from the roots of Anthurium andraeanum and some algae, and cut off the old and decaying roots. This helps to increase the amount of dissolved oxygen in the water. Usually, the water is changed within 2 or 3 days. It can be replaced once a week in winter. Each time the water is changed, a nutrient solution will be added. During the hydroponic blooming period, as long as you soak two roots of Anthurium andraeanum in water, the other roots will be exposed to the air so that the roots of Anthurium andraeanum can breathe. Insufficient dissolved oxygen in water can lead to root rot.

3. Light and temperature

Anthurium likes a warm semi-negative environment to avoid sunlight. In the process of cultivating hydroponic Anthurium andraeanum, we should pay attention to the position, better in the ventilated and ventilated place, in order to avoid strong light. In summer, the temperature of the environment around hydroponic flamingos should not be higher than 28 °C. In winter, the culture temperature of hydroponic flamingos should not be lower than 14 °C. Below this temperature, the fire crane flower will freeze to death. During the hydroponic blooming period, as long as you soak two roots of Anthurium andraeanum in water, the other roots will be exposed to the air so that the roots of Anthurium andraeanum can breathe. Insufficient dissolved oxygen in water can lead to root rot.
