How to raise Wandai orchid Wandai orchid breeding methods and precautions

Wandailan likes to grow in warm places and is currently distributed in many parts of our country. At present, Wandailan is very popular with consumers on the market, and people mainly breed it for viewing. However, in the process of breeding, it is also necessary to master some skills, otherwise it will cause some problems, serious will cause plant death.

How to raise Wandailan

1. Potted soil: the root of Wandailan belongs to aerial root, which can be applied to any medium with good drainage, such as snake sawdust, broken bricks, charcoal, coarse gravel sand, etc., whether used alone or mixed, it is a good basin soil.

2. Lighting: Wandailan usually needs strong light, 40-50% shading net in the local high temperature season, and even no shading in winter.

3. Temperature: Wandailan prefers high temperature environment, the most suitable temperature is 20-30 ℃, and the temperature as high as 35 ℃ in summer has little effect on its growth.

Culture methods and matters needing attention of Wandai orchid

1. Culture methods:

1. Watering: Wandai orchids should reduce watering in the near flowering period to promote flower bud differentiation, watering every morning or evening every 1-2 days in summer and about 3-5 days in winter, cold spell should stop watering, watering should be thoroughly watered at one time, and then watered again after the plant is dry, and the humidity in the air should be kept at 60%.

2. Fertilization: Wandailan was given slow-acting fertilizer in spring and autumn, water-soluble liquid fertilizer was used 1000-2000 times at ordinary times, sprayed every 10 to 15 days, N-P-K ratio for small seedlings was 3:1:1, N-P-K ratio for middle to big seedlings was 1:1:1, and N-P-K ratio for flowering plants was 1:3:2. The principle is to apply more thin fertilizer to prevent fertilizer damage.

3. Change the basin: Wandailan should not change the basin frequently. Unless disturbed by diseases and insect pests, the basin can be changed at least once every 3 years. The Wandai orchid in spring is about to enter the vigorous growth period, which is a good time to change the basin.

2. points for attention:

Wandailan needs to plant well-ventilated and well-drained plant materials, such as water moss (water plants), snake sawdust, pine bark and small stones, which can be changed about every two years in spring or autumn. It is better to soak the plant material for 1 or 2 days before planting and then use it after drying in the sun.

What if the leaves of Wandailan turn yellow?

1. Water is yellow. Water yellow is the long-term accumulation of water in the flowerpot is too wet, resulting in a lack of oxygen in the soil. This condition will cause a small number of roots to rot, but also lead to a decline in the ability to absorb water and the ability to absorb fertilizer. The new leaves will appear dark yellow and have no luster on the surface. The tip of the new leaf shrinks, and the branches become small and yellowish green.

Treatment: the soil should be loosened in time, the amount of water should be reduced, and the use of fertilizer should be stopped. in serious cases, the soil and plants in the basin can be taken out to dry and then put back.

2. Fat yellow. Fat yellow is caused by excessive fertilization, especially the yellowing of leaves caused by nitrogen fertilizer. This situation is that the new leaves are thick and glossy, the surface of the leaves is uneven, and the old leaves slowly turn yellow and fall.

Treatment method: should stop fertilizing and increase the amount of water to desalinate nutrients. When the fertilizer is insufficient or the plant pot is small, when the roots in the flowerpot are old and too dense, the leaves of the flower plant will be thin and yellow. To change the basin soil, it is generally better to do it during the period from Rain Water to the Beginning of Summer.

Disease and control of Wandai orchid

1. Soft rot. Prevention and treatment: improve growth conditions, increase ventilation, reduce temperature and humidity. Remove the susceptible site, smear with antibiotic powder, do not water for a week, can stop the spread of the disease. Streptomycin 1000-fold aqueous solution, stone-sulfur mixture or Bordeaux solution were sprayed once a week.

2. Leaf blight. Prevention and treatment: remove diseased leaves and spray 500x Dasheng-45 or 1000 times Haosheng. Susceptible plants should avoid Rain Water or suspend watering to prevent the disease from getting worse. Spray 500 times Dasheng-45 regularly once a day as a precaution.

Wandailan must pay attention to temperature control when breeding, low temperature in winter should be put indoors, and high temperature in summer should be shaded. If the phenomenon of leaf yellow appears in the process of breeding, we should first find out the reason, and then solve this phenomenon from the root.
