Can you grow orchids in the cold dew season, and can you raise orchids in the open air in autumn

It is also possible to plant orchids during the cold dew season.

It is okay to grow orchids to avoid high temperatures and freezing seasons.

The first step in planting orchids is to serve pots, and generally speaking, the faster you pot, the better the orchid will grow. The farmer has made a comparison, and the wild orchids transplanted in the spring (at the end of March of the solar calendar) will grow new roots in 20 days at the earliest; Wild orchids transplanted in autumn (the end of September) will give birth to new roots in 40 days, and the planting materials used are the same, as is the management and maintenance environment, which shows that new roots are born faster in spring.

Isn't transplanting orchids in autumn as good as spring? If you only look at the speed of new roots, it is true that spring is much faster. In fact, the growth rules of plants in spring and autumn are different, and listen to the farmer slowly.

The climate is getting warmer in spring, which is the season when everything begins to grow, and the sap in the plant body flows.

Autumn is a colder climate, plants slowly begin to converge, dormant leaves, fallen leaves, orchids at this time mostly have buds, or flower buds have been conceived. Then, the main waiting object of the reed head is the flower buds and flower buds, which are the laws set by the plants themselves in order to reproduce, so the energy supplied to generate new roots is much less, and the weather is getting colder, and the slow generation of orchid roots is understandable.

In fact, the orchids transplanted in autumn also have the advantage, that is, after slowly potting, the new seedlings will grow in the next year than those transplanted in the spring, and the seedlings will grow into strong grass in the same year.

Cold dew is the seventeenth of the 24 solar terms and belongs to the fifth solar term of autumn. Dou Zhi Wu; The Sun reaches the ecliptic longitude 195°; On October 7 and 9 of the Gregorian calendar every year, the festival is celebrated. Cold dew is a solar term that reflects the characteristics of climate change, after the cold dew solar term, the days are getting shorter, the nights are getting longer, the sunshine is decreasing, the heat is slowly receding, the cold is gradually growing, the temperature difference between day and night is larger, and the morning and evening feel a little chilly.

From the perspective of climatic characteristics, in the cold and dew season, the autumn in the south is getting stronger, the air is cool and the wind is cool, and the rain is less and dry; The vast areas of the north have entered or are about to enter winter from late autumn. [1][2][3]

Yuan Wu Cheng's "Seventy-two Candidate Explanations of the Lunar Order" said: "On the September Festival, the dew is cold and will condense. The meaning in the work is that the temperature of the cold dew is lower than that of the white dew, and the morning dew on the ground is cold and is about to condense.

The ancients regarded cold dew as a sign of the gradual development of cold air. After the "cold dew" solar term, the heat subsides, the cold gradually arises, and the weather gradually turns cold. [4][5][3]

After the cold dew, the temperature in most parts of southern China continued to drop. The average daily temperature in southern China is less than 20, and even in the areas along the Yangtze River, it is difficult for the temperature to rise above 30, while the minimum temperature can drop below 10. Due to global warming, the date of temperature drop may be delayed.

Except for a few lowlands in the valleys, the average temperature of the Northwest Plateau is generally lower than 10 for 5 days. [6][7]

Chinese name. Cold dew.

Foreign name. cold dew

Represents the meaning. The temperature is lower than in the white dew, and it is slightly chilly in the morning and evening.

Climatic characteristics. The temperature drops, the rain is less dry and the morning dew is cooler.

Season. Autumn.

In autumn and winter, it can be raised outdoors in the open air.

First, it can be outdoors in autumn and winter, but it must be maintained indoors when the temperature is too low.

We know that there are many varieties of orchids, such as orchids, spring orchids, etc., which are more precious, but due to the different varieties, they can tolerate different low temperatures, such as spring orchids and wild varieties of orchids can tolerate low temperatures of more than ten degrees below zero, but if it is a potted plant, less soil, the ground temperature can not keep up, zero degrees must be indoors, otherwise it is very easy to suffer from frost damage, so spring orchids must be maintained indoors in winter.

However, if the spring orchid wants to bloom beautifully, they have a special requirement is low-temperature vernalization, which means that there should be a period of low-temperature exercise in winter, which can transform the over-vigorous vegetative growth into reproductive growth, and the low-temperature vernalization temperature is roughly two to five degrees, and the minimum time is one month or even longer, so the spring orchid should not be too early in winter, as long as the temperature is not lower than zero degrees, it can be maintained outdoors, which is conducive to flowering and improving the quality of flowering.

If you build Lan Molan, the low temperature that can be tolerated is about five or six degrees, so these two winters must also be maintained indoors. ）

Second, outdoor maintenance is the most suitable during the growing season.

In spring, everything recovers, and the best place to maintain orchids is under the outdoor big trees, which can not only shade the strong light, but also bathe in the soft light of the weak light, which is very similar to the wild survival environment of orchids, which is very beneficial to the growth and flowering of orchids.

In summer, the maintenance under the outdoor tree is more beneficial, not to mention the right light, but more importantly, it can be ventilated and breathable, and the wind blowing in nature can maintain the coolness of the environment, which will allow the orchid to avoid the occurrence of stem rot and soft rot, which is of great significance for the orchid to spend the summer safely.

In autumn, the outdoor environment not only has light, not only ventilation, but most importantly, outdoor maintenance, at this time there is a large temperature difference, we know that orchid flower bud differentiation is required a certain temperature difference, with this, these are very beneficial to the flower bud differentiation of orchids, it can be said that without these, orchids are difficult to flower.

Third, what should be paid attention to in the outdoor maintenance of orchids?

Although orchids are suitable for outdoor maintenance, due to close contact with nature, we should pay attention to prevent some insects, such as ants, snails, etc., which will provoke aphids and even eat orchid leaves or roots; In addition, to maintain orchids outdoors, we should also pay attention to the rainy weather on cloudy days, and pay attention to indoor ventilation, after all, the ventilation and permeability of the trees and the mountains are different, and long-term water accumulation is prone to diseases or root rot.

Orchid is one of the four gentlemen in the flower, it is very beautiful when it blooms, and the leaf color is evergreen and beautiful in all seasons, even if it is not a flowering period, it is a very good foliage flower. When it blooms, it is full of fragrance and refreshing. When you usually care for orchids, you can keep them outdoors or indoors, but it's best to keep them indoors.

Because orchids are shade-tolerant flowers, if they are maintained outdoors, they can easily burn the plants when the weather is hot, and if the weather is cold, the plants are likely to get frostbitten.

Methods of indoor maintenance of orchids.

1 .Illumination.

Although orchids have a certain negative tolerance, in the process of maintaining orchids, it is necessary to ensure that there is sufficient light. When maintaining orchids indoors, we need to put the orchids on a sunny balcony for maintenance, which can give the orchid proper light, promote flowering, and prevent the plant from being burned by the sun during the hot season.

2 .Temperature.

If you are maintaining orchids in the southern region, you can keep the orchids outdoors, because the temperature in the southern region is generally high, and even in winter, it is not very cold. If it is a northern region, the temperature in winter is relatively low, and if it is kept outside, it is easy to cause frostbite.

3 .Watering.

Many friends who maintain flowers and plants should have heard of the term dry orchid wet chrysanthemum, that is to say, when maintaining orchids, it is better to be dry, and the soil should be wet when maintaining chrysanthemums. In the process of maintaining orchids, if the soil is too wet, then it is easy to cause the root system of the orchid to rot. Therefore, when maintaining orchids, it is necessary to achieve the principle of seeing dry and wet, that is to say, to wait until the soil is dry before watering, watering does not need to be too thorough, only the soil needs to be moist.

If you raise an orchid in autumn, you should give it the right sun to bloom more often.

This depends on the variety, if it is a wild variety, it must be no problem, of course, it also depends on your environment, if it is dozens of degrees below zero in the north, it will definitely not work. Just think about the natural environment in which orchids grow, which are generally found in places with warm and humid climates.

Autumn is a time when the sun is shining during the day. You can move the orchid outside and let the orchid bathe in the sun, but still avoid the middle of the day. Well, the time when the sun is blazing.

So as not to hurt the back of the orchid. There is a wilderness handover. You night.

Seven tenths of a degree dropped. Orchids can be made. One arrived.

Indoors. This can assist the growth power of the orchid.

Orchids can be planted in winter, but due to the weather in winter, if the maintenance is not good, it is easy to lead to freezing death, frostbite, empty roots and black spot disease, and even death, and finally it will fall short. Therefore, when planting orchids in winter, we must pay attention to good maintenance.

It is also very important to choose a room to place the orchid in the winter, you must pay attention to the sunlight to ensure photosynthesis, the temperature of the orchid can not be lower than 1 degree, to prevent frostbite, if it is below zero, move away quickly. When the weather is too cold, heat it with an electric heater.

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.

If the long-term dryness causes the strong orchid root to become empty, when you see the orchid soil dry, you should moisten the edge of the orchid soil basin and see that the topsoil is moist. The correct approach is to "don't dry and don't water", and "pour it thoroughly". Orchid pots that are too dry can be placed in water to soak in orchid pots.

The flowering period of the cold orchid is from August to December every year, the plant can bloom all year round, but it mainly blooms at the beginning of winter, in the process of cultivating the cold orchid, it is necessary to apply foliar fertilizer frequently, spray potassium dihydrogen phosphate more, improve cold resistance and disease resistance, and appropriately increase the frequency of sunbathing, and the sunshine time can not be less than 4 hours a day during the flowering period.

The cold orchid period is from August to December every year, it has a wide variety of varieties, and can bloom in four seasons of spring, summer, autumn and winter, and the cold orchid usually blooms in the winter season, has a certain cold resistance, and the vitality is very tenacious.

When the cold orchid is flowering, it is necessary to apply foliar fertilizer, mainly potassium dihydrogen phosphate, and apply it once every 20 days to improve the cold resistance of the plant, and avoid topdressing thick fertilizer, otherwise the leaves of the cold orchid will be burned and reduce the ornamental value of the flowers.

During the flowering period, the cold orchid is susceptible to diseases and insect pests, mainly virus diseases and aphids, which will damage the flowers, so in the cold orchid flowering period, it is necessary to spray disinfection and insecticides regularly to keep it in a healthy growth state.

Hanlan likes to grow in a sunny place, especially in the flowering period, to ensure more than 4 hours of light time every day, and the cold tolerance of Hanlan is not strong, when the temperature is lower than 0 degrees Celsius in winter, it is necessary to cover the film to keep warm to prevent frost damage.

Orchids can be maintained in the open air, and they can be kept under outdoor trees, which can not only shade strong light, but also bathe in weak light, which is very beneficial to its growth and flowering, but it is not suitable for outdoor planting in summer and winter. Orchids cannot be kept outdoors for a long time, otherwise in the event of heavy rain, it will cause too much water in the pot, and its roots will be in a state of sufficient moisture for a long time, which will cause the roots to rot.

Orchids are cultivated in the open air.

The best place to maintain orchids is under the outdoor tree, which can not only shade the strong light, but also bathe in soft light, which is very similar to the wild survival environment of orchids, and is very beneficial to the growth and flowering of orchids.

Raised in the open air in summer.

Summer and summer can be cultivated in the open air, but the orchid should not be kept outdoors for a long time, it is suitable for growing in a cool and ventilated environment, the temperature is higher during the summer, the light is too strong, when the room is long and the silver is cultivated, it should be placed in a shaded and ventilated position to avoid the orchid being burned by the scorching sun.

Raised in the open air in winter.

Orchids should not be maintained in the open air in winter, the temperature is generally low in winter, and if it is kept outdoors, it may be frostbitten, so it must be moved to a warmer place indoors for maintenance, and ensure that there is sufficient sunlight, which is conducive to orchids to give birth to flower buds.

Orchids are planted outdoors.

Orchids can be planted in the ground in areas where the outdoor temperature is not lower than 5 degrees Celsius in winter, and the location should be selected on the south-facing and semi-shady ground, with walls or other trees to shade in summer, and in winter, choose a south-facing and slightly sunny place with high humidity in the surrounding environment.

Orchids are put outdoors on rainy days.

There is no problem with orchids outside on a light rainy day, when encountering a thunderstorm or a few days of light rain, remember to move the orchid back to a ventilated environment to avoid the rain, too much rain will cause the orchid to grow slowly, and if the rainwater accumulates in the soil seriously, it will cause the orchid to die.

Pay attention to the main points of raising orchids in the open air.

Six days to raise orchids to create a suitable for its growth of local humidity, it likes yin and fear of the sun, summer morning can let the sun shine directly on the orchid, at noon need to use a shading net to block the sun, but also pay attention to the rainy weather on cloudy days, to avoid long-term waterlogging, otherwise it is easy to appear disease or rotten roots.

Orchid outdoor planting points.

Orchids can be cultivated outdoors, but it is not possible to be cultivated outdoors for a long time, if it is cultivated outdoors for a long time, it will lead to too much water accumulation in the Huijian pot, and its roots will be in a state of sufficient water for a long time, which will lead to root rot.
