What do you need to pay attention to when raising orchids in winter, and how to maintain orchids in

China Bio-Organic Fertilizer Trading Network: It has come to the cold winter, the temperature has plummeted, and orchids need to be cared for. Orchids should be kept indoors, preferably in a sunny place, which is beneficial to the growth of orchids.

For wintering orchids, the room temperature should be controlled between 5 and 15. If the room temperature is too high, the flower stem grows slowly, the flower bud development is poor, and it is easy to shrink the flower buds that have been formed and die.

1. Anti-freezing. Orchids with sufficient sunlight in winter are conducive to the growth and flowering of the following year. At the same time, it can also improve the cold resistance of orchids during wintering.

If the number of orchid pots is small, you can put the orchid pot in the inner balcony to keep warm, and the sun is oblique in winter, and the orchid can still bathe in the glory of the sun in the inner balcony and enjoy its warmth. If you advocate raising orchids naturally and do not want to cultivate them with high temperature and humidity, the orchids can be safe and sound in this simple greenhouse when the outside temperature is generally 2° (local weather forecast).

2. Orchids generally do not need to be fertilized during the hibernation period of orchids in winter. Generally, when the orchid is changed every two years, the soil has been replaced with sufficient nutrients, and no fertilizer can be applied at all in winter, and biological organic fertilizer can be appropriately supplemented. However, during the growth period of Chunlan and Hanlan, a small amount of phosphorus and potassium fertilizer can be sprayed on the foliage.

In addition, indoors, orchids can be given more light, if the light is insufficient, you can use lights to supplement.

3. Ventilation. While doing a good job of anti-freezing, special attention should be paid to ventilation. The ancients have long helped us summarize the secrets of raising orchids in winter, that is, "ten deaths and nine stews", that is, if the orchid dies or is injured in winter, it is mainly "stewed".

Especially in a small orchid room, the sun on a sunny day can cause the indoor temperature to rise sharply to more than 20 degrees, or even more than 30 degrees, and then the orchid will be damaged by the stuffiness. The "Ancient Books of Orchid Cultivation" calls it "steamed", which is one of the reasons why the orchid has dark spots or dies in the following year.

Raising orchids in winter, pay attention to four details, which are conducive to flowering and wintering.

Watering should not be too diligent.

Orchids in winter are limited by low temperatures, so their metabolism slows down. To water it at this time, be sure to reduce the frequency of watering. Of course, you can't help but pour it.

In short, dry is watered, wet is stopped, appropriate dry for the principle. In the choice of water quality, tap water can be used based on the principle of convenience. However, it is best to leave tap water for two days before watering the flowers.

There is no shortage of light.

Masters of raising orchids understand this sentence, that is, "the yin orchid leaves of the mountain are long and the flowers are thin, and the yang orchid leaves of the mountain are short and the flowers are many". This sentence actually illustrates the orchid's requirements for light. If there is less light time, it will not affect growth, but it will affect flowering.

The light in winter is not strong, so it is completely possible to place the orchid in the light to maintain.

Fertilization is mainly based on thin fertilizer and frequent application.

Orchids are fat-loving flowers, and they need to be supplemented with nutrients in time when they are maintained in winter. After all, winter and spring are the peak flowering seasons for orchids, so the most needed fertilizer at this time is the variety that promotes the differentiation of flower buds. In the flower world, the recognized flower-promoting fertilizer is potassium dihydrogen phosphate.

Therefore, to maintain orchids in winter, it is recommended to use potassium dihydrogen phosphate thin fertilizer and apply frequently. The best time for fertilization is in the evening, dilute potassium dihydrogen phosphate 1000 times and water it directly into the pot of orchids. Of course, it can also be sprayed.

Temperature doesn't matter, humidity is.

Orchids do not have high requirements for ambient temperature. In winter, the indoor temperature is around 20 and fine. However, it is important to pay attention to the humidity issue.

The indoor space in winter is too dry, which is very unfavorable for the growth of orchids. Therefore, the air humidity is increased to prolong the flowering period of orchids. The way to increase the humidity is to spray it or put a plastic bag over the orchid.

Reproduction of orchids.

In terms of propagation, orchids, like most flowers, can not only be sown and reproduced, but also propagated by branches. It is best to use the fruit that has not yet cracked for sowing propagation, and after sterilizing the surface with 75% alcohol, remove the seeds and sow again. From sowing to transplanting, it takes half a year to a year, which is slower than that of rametre propagation.

Branching propagation, in spring and autumn can be carried out, generally once every three years, after the division of the pot, first watered permeable, and then placed in the shade for about half a month. During this time in the shade, the soil inside the pot should be kept moist.

The orchid winter maintenance method is as follows:

1. Pay attention to anti-freezing.

In winter, orchids must be kept warm, the room temperature should be controlled between 5 and 15 degrees Celsius, and the sun should be kept in full swing.

2. Reasonable ventilation.

Because the temperature is low, if the window is not opened in winter, it is easy to cause air circulation, indoor closure and blockage, which is not conducive to the growth of orchids, so when there is sun, you can open the windows to ventilate the orchids, which is conducive to growth.

3. Control watering.

Winter orchids are dormant and the water does not evaporate too much, so the frequency of watering should be reduced, and watering once a month is fine.

4. Kill insects in time.

There are many pests after winter, but they will not be active outside as in spring and summer, and they are basically invisible, so you can sprinkle poisonous soil at this time, and sprinkle poisonous soil on the place where you place the flower pots, because the pesticide has a long effect on the fine soil, and after a period of time, the pests will be killed.

The ornamental value of orchids.

The orchid is a unique style of flower, and its ornamental value is high. The flower color of the orchid is light and elegant, among which the tender green and yellow-green are the majority, but especially the amateur is precious. The aroma of orchids is clear but not turbid, a pot in the room, fragrant.

Hand Pei Lan Rui two or three planting, the day warm wind and the second opening; I don't know the fragrance in the room for a long time, and there are butterflies flying when I push the window. This poem of the ancients vividly expresses the fragrance of orchids. Some of the orchids are dignified and beautiful, and some are graceful and luxurious, and they are full of changes.

The leaves of the orchid are bright green all year round, both rigid and soft, and have a beautiful posture, even if it is not in flowering, it is like a living work of art. "The weeping dew is chaotic, and the wind shadow is slanted; The laity is more than that, and the leaves are better than the flowers." This poem is used to describe the graceful beauty of orchid leaves.

Put a few pots of orchids, decorate the room, suddenly feel full of business, the day of blooming, the fragrance bursts, will make you feel vibrant, relaxed. <>

In winter, the weather is getting colder, and the orchids placed outdoors are easily attacked by cold snaps, so they must be moved indoors in a sunny place in time to maintain. Ensuring that the orchid has sufficient sunlight is extremely beneficial to the pregnant buds and flowering of the orchid.

After entering the room, the room temperature should be controlled between 5 and 15, which can be met by the average family. But the room temperature should not be too high, too high will cause slow growth of flower stems and poor bud development.

Orchids do not need to be fertilized during hibernation. The roots of orchids have a symbiosis of rhizomes and need to be repotted every other year, and the soil is rich in nutrients, so there is no need to repot. However, for Chunlan, it will grow in winter, and it is necessary to replenish nutrients in time and spray a small amount of phosphorus and potassium fertilizer on the foliage.

Winter potted orchid cultivation method:

When cultivating potted orchids in winter, move them indoors before the outdoor temperature drops to 10 degrees Celsius, and use heating equipment to raise the temperature around the plant to more than 16 degrees Celsius, so that the orchids can grow and bloom smoothly in the cold winter.

When maintaining potted orchids, place the plants on the windowsill on sunny days to allow the branches and leaves to carry out light and rewilding, and on rainy days, you need to move the potted orchids away from doors, windows and sinks, and turn on the incandescent lamps to provide more than 4 hours of light for the plants every day.

On the premise of keeping the indoor warm in winter, water the potted orchids every 4 to 5 days to keep the moisture in the soil at about 75%, if the temperature cannot be controlled, wait until the potting soil is dry, and then water the orchids to prevent the soil from accumulating water and causing the fleshy roots of the plants to rot.

Before moving potted orchids indoors in winter, spray Tobuzin or carbendazim indoors once when the weather is fine, in case the orchid production is sick and insect pests due to too high room temperature, and note that when there are scale insects indoors, you need to spray nitric oxide once for the plants.

Growing orchids in winter is mainly concerned with 3 aspects, indoor temperature, watering and ventilation. Pickpocketing orchids will stop growing in the winter and enter the dormant period, and the management of this period will directly reflect the growth trend of the orchid in the coming year.

1. Pay attention to prevent freezing.

It is also very important to choose a room for orchids to place when wintering, you must pay attention to sunlight to ensure photosynthesis, the temperature of orchids should not be lower than 1 degree to prevent frostbite, and if it is below zero, move out quickly. When the weather is too cold, heat it with an electric heater.

2. Pay attention to regular ventilation.

In order for the orchid not to freeze, the orchid needs to be in a well-ventilated place so that the orchid will not freeze. When the temperature is high, open the window in time to promote air convection.

3. Pay attention to prevent long-term overhumidity.

Winter does not get wet means that the orchid pot can not be kept very warm for a long time, and it is even more important to avoid getting wet again before it dries after being wet, which will lead to the root of the orchid will rot and even die. After the orchid pot is thoroughly watered, it is too wet and placed in a ventilated place to bask in the sun until it looks like the potting soil is not very moist.

What kind of breed does the landlord raise? The upstairs copy is Guolan's method of wintering! In addition, the national orchid seems to be the version in winter.

Not growing, in fact it differentiates the buds inside the right and accumulates nutrients so temperature. Light and moisture are important! The temperature of Chunlan Huilan should not exceed 10 degrees, and it is not conducive to flower bud differentiation, and the flower buds with good differentiation are not easy to bloom in spring.

Do not lower than -5 degrees Celsius, if it is low, it will cause frostbite. Jianlan and others require higher temperatures! Molan is not lower than fifteen degrees, and there is a temperature difference of three to five degrees!

It can accept full sunshine, and Melan should be covered at noon! Because orchids don't need much water to dormant in winter! So don't water too often!
