When is the flowering period of cold orchid (methods and techniques of cold orchid cultivation)

Now it has entered the light snow solar term, and it is freezing outside, obviously feeling cold. It is reported that the highest outdoor temperature is around 6 ~ 7℃, and the lowest temperature has been hovering around 0℃. Now, most flowers and green plants have entered indoor conservation management.

So, can orchids bloom in the cold winter? How to maintain it indoors at this time? I am a flower farmer. Today, we will look at whether orchids bloom in winter and how to maintain and manage them.

First, can Hanlan blossom in winter?

As we all know, there are many kinds of orchids, and orchids bloom all year round. Although it is winter, orchids are still in full bloom.

Cymbidium hybridum, Cymbidium hybridum and Spring Sword can all bloom in late winter and early spring, especially during the Spring Festival. However, Hanlan blooms in the cold winter. Planting flowers and plants today will briefly introduce the situation of Hanlan.

1, cold cold bloom.

Hanlan, when you hear this name, you can feel that it is open in the cold winter. That's true! Under normal circumstances, Hanlan is open from 10 to 1, which is in late autumn and winter, and it is snowing heavily, making it even more arrogant.

Of course, other kinds of orchids will bloom in cold winter if they are properly maintained and managed, and cold orchids are the main varieties that open this season.

2. Hanlan's habits and characteristics

First, although it is called Lenglan, it is not cold-tolerant.

The indoor temperature should not be lower than 5℃ at night in winter, otherwise it will affect the normal growth and flowering; Daytime 15 ~ 20℃ is more suitable, and there should be a certain temperature difference between day and night. Then, you will enjoy orchids and smell the fragrance every day.

Second, although it blooms in winter, it has a long flowering period and many colors.

The flowering period of cold orchids is generally in early winter, but some varieties of cold orchids may bloom in spring, summer and autumn. Hanlan's petals are rich, peculiar and colorful.

Third, in the cold winter, it is difficult to cultivate cold orchids.

Indoor cultivation of Chinese cymbidium will be affected by factors such as region, temperature, humidity and ventilation. It is not easy to raise cymbidium in cold and dry seasons. Now, let's talk about planting flowers and plants.

Second, how to maintain and manage the cold orchid in winter?

The management of orchids needs to be very careful. A friend said: if it's so troublesome, I'd rather not keep it. In fact, the process of cultivating orchids is just a kind of happiness; And seeing orchids grow up slowly is a kind of harvest; When orchids are in full bloom, it is a kind of happiness.

1, properly control the temperature.

In winter, the temperature control of indoor orchid cultivation is very important. When cold orchids bloom, they don't like high temperature.

It is good to keep it between 5 ~ 20℃ at ordinary times. This can not only ensure the flower buds to bloom, but also prolong the flowering period. Of course, there must be a certain temperature difference, and the temperature should be appropriately lowered at night and raised during the day to create an outdoor natural ecological environment.

pay attention to

Han Lan is not cold-tolerant, but she doesn't like high temperature either. Let's not put them near the heater or stove. If the temperature is too high, it will affect normal flowering.

2. Properly control watering.

The temperature is relatively low in winter, so even indoors, water should be controlled. Prevent excessive watering, slow evaporation, easy to cause water accumulation, and less light, poor ventilation, easy to cause diseases.

First, properly control watering. The soil should be kept slightly wet, preferably not too wet.

The second is to try to choose to water at noon. We can choose to replenish water at noon when the sun is shining. And make the water temperature as close to room temperature as possible to prevent the roots from being damaged.

The third is to try not to fall on the leaves. As we all know, water evaporates slowly in winter to prevent leaves from rotting. You can open the window for ventilation at noon.

pay attention to

However, the flowering period of Hanlan needs certain water protection, and it can't be drought and water shortage for a long time to control watering. Similarly, it will also affect the opening of flowers. If the soil is already very dry, you can choose sunny noon and replenish water appropriately to make the basin soil slightly wet, so there is no need for big water irrigation.

3. Increase the illumination appropriately.

Cold orchids are not hardy. Appropriate increase of light in winter is not only warm and comfortable, but also increases photosynthesis, making orchids in cold regions more robust, with longer flowering period and more gorgeous colors.

Therefore, in the flowering period of Hanlan, don't forget to strengthen the illumination time, increase the illumination rate and promote photosynthesis. At the same time, it can also reduce the occurrence of diseases, prevent the occurrence of black rot, and serve multiple purposes.

way

We can put cold orchids on the balcony to breed, which can receive sunlight during the day and keep the temperature low at night. And the temperature of the balcony can be controlled by sliding doors. If the temperature is too high, you can close the sliding door and lower the balcony temperature appropriately, and vice versa.

4. Appropriate supplementary fertility.

Some flower friends think that when orchids bloom in cold areas, don't rush to fertilize them to avoid hurting the flowers. In fact, it is necessary to supplement fertility appropriately.

When orchids bloom in cold regions, they need to absorb and consume certain nutrients to ensure orchids bloom.

Therefore, fertility should be properly supplemented. I grow flowers and green plants. Generally, I use foliar spraying to supplement phosphorus and potassium fertilizer, and potassium dihydrogen phosphate is good. I can dilute it into 1000 times water solution and spray it with water.

pay attention to

I can briefly sum up as follows: three are not important. Try not to be too frequent, just once a month; Try not to spray the flower heart to prevent suppuration; Try not to spray at night to prevent slow evaporation. After spraying, try to ventilate.

5. Proper ventilation.

Although it is freezing outside, it is warm as spring indoors. Some friends are worried about frostbite orchids and often close their management. In fact, this is not conducive to the flowering and growth of orchids in cold regions.

The indoor temperature is still relatively high in winter. Proper ventilation is not only beneficial to human health, but also very beneficial to orchid growth. It can prevent diseases caused by high temperature and high humidity and reduce the occurrence of yellow leaves and rotten roots.

way

In the sunny noon, open the window for ventilation, or move the orchids to the sunny balcony to bathe in the sun.

Of course, if it is sunny and warm outside, you can also move outside to receive the sunshine, which is better, but it is a bit troublesome.

Of course, when the outdoor air is cold and the snow is fluttering, try to reduce the ventilation.

3. What are the precautions for flowering in winter?

1. Before flowering, reduce the movement of flowerpots.

After Han Lan grows buds, it is recommended not to move the flowerpot as much as possible. First, moving back and forth is easy to cause buds to shake and prevent loss. Second, the direction changes after moving, which is easy to cause the flower stem to bend.

Don't touch it with your hands when it blooms.

When the orchid blooms, we expect the orchid to bloom, but we often can't wait. Sometimes we will encounter buds, so we must be careful not to touch them, so as not to affect the normal flowering of Hanlan and reduce its ornamental value.

3, after flowering, pruning in time.

This is easy to understand, but after the cold orchid withers, it should be pruned in time to prevent the nutrients from continuing to be consumed, and it also affects the appearance. Trim as close to the bottom as possible about 3 cm.

Inductive summary

Seeing a friend's message, I feel that planting orchids is very complicated and troublesome. Planting flowers and telling friends that the maintenance and management of orchids is not as complicated as I thought. Most of them are basic common sense, and they are matters that should be paid more attention to in daily maintenance. As long as you grasp it, raising orchids is actually very relaxed and happy.
