Gentleman orchid winter maintenance?

When Cymbidium was cured in winter, the best growth temperature was 15: 25 ℃. When moving indoors for the winter, maintenance should be carried out according to the orientation and lighting of the house. In the south of our country, if the house is facing south to the sun, it can be placed by the indoor window and keep the room temperature above 0 ℃, so that it can pass the winter safely. Generally speaking, the room temperature is higher in early winter, and most orchids are still growing indoors, so you can continue to apply fertilizer, which is good for growing branches and leaves and budding and blooming in the future. If the indoor heating equipment is installed and the constant temperature is above 10 ℃, the orchid can continue to grow throughout the winter, and the orchid can blossom ahead of time by applying fertilizer once every 7 days.

If the room temperature drops below 10 ℃, fertilization should be suspended, because the orchid has been in a period of slow growth or dormancy, more fertilization is not only difficult to absorb, but harmful to the root system.

If the house is facing north, although there is no sunshine indoors throughout the winter, as long as the indoor temperature does not appear below 0 ℃, put it in a relatively warm place in the room, no cold wind can blow, and the basin soil is dry but not too wet, the magnolia can also experience a long cold weather safe and sound, and the big tree outside after spring can bloom beautifully.

As for the small plants of Cymbidium, when they spend the winter in the sunny room, they can still grow new leaves with plastic film bags and put them in a sunless room facing north, and if they are covered with plastic bags, they can also pass the winter safely. the above is the introduction to the winter maintenance of Cymbidium.

Maintenance of orchids in winter | how to maintain orchids in winter? The author mainly introduces the maintenance of Cymbidium in winter and how to maintain it in winter. Magnolia raise pigs in winter mainly pay attention to the following five points: Cymbidium is native to South Africa, perennial evergreen herbaceous flowers, like warm and cool climate, afraid of high temperature and cold, summer dormancy, autumn and winter growth, therefore, strengthening winter tube is the key to cultivation. The main points are as follows:

First, protecting leaves, fat and strong flowers, colorful chlorophyll, short, wide, thick, green, bright and strong leaves are the characteristics of healthy orchids, which are the basis for promoting flowering and improving ornamental value. To maintain strong leaf quality, in addition to providing reasonable fertilizer and water, it is necessary to keep the leaf surface clean in order to improve photosynthetic efficiency. The methods of leaf protection are as follows: one is to wash the leaves regularly and spray or wipe the dust on the leaves with the same water to keep the leaves clean; the other is to spray fungicides in time to prevent the occurrence of leaf spot, leaf blight and stem rot and ensure that the leaves are green and the flowers are beautiful. Second, fertilizing Magnolia has the fastest vegetative growth rate in winter and needs the most nutrients. therefore, it is very important to apply winter fertilizer well. Before entering the room, flowerpots should be watered with bone powder, fried sesame, cooked soybeans or compound fertilizer every 15 to 20 days, and the roots can also be watered with soaking solution of animal and plant residues. It is necessary to ensure that the fertilizer is ripened and applied lightly to prevent the injury of thick fertilizer.

Third, watered magnolia is a fleshy root, angry and afraid of water stains. In addition, the leaves of Cymbidium have waxy layer, the temperature is low in winter, and the transpiration and evaporation of water are less. Therefore, watering should not be too much, only combined with fertilization watering, to keep the basin soil moist. Must not be flooded with water, resulting in rotten roots and dead seedlings.

4. The most suitable temperature for the growth of Cymbidium was 15 ℃ to 25 ℃, 10 ℃ stopped growing and 0 ℃ suffered frost injury. Therefore, it must be kept warm and frost-proof in winter. After the flower stem is extracted, it is suitable to keep it at about 18 ℃. If the temperature is too high, the leaf and flower moss are only long and thin, the flower quality is poor, and the florescence is short; the temperature is too low, the flower stem is short, it is easy to be born prematurely (flowering), which affects the quality and reduces the ornamental value.

Fifth, dimming gentleman orchid likes to scatter light, avoid direct strong light. Winter indoor maintenance, flowerpots should be placed in a place with plenty of light. Especially before flowering, there should be good light, which is beneficial to the development and firmness of flower buds. After flowering, proper cooling, avoiding strong light and keeping good ventilation are beneficial to prolong the flowering period.

Key points of maintenance of Magnolia in winter

Gentleman orchid is a kind of flower that people like. It likes temperature, light, can not bear the cold, easy to survive but not easy to raise. Before that, some flower friends asked how to maintain the gentleman orchid in winter. The following editor will talk about the key points of the maintenance of gentleman orchids in winter in combination with the maintenance experience of Hua you:

If you want to raise a good gentleman's orchid in winter, you should pay special attention to strengthening management and make more efforts in the following five links.

1. Soil and fertilizer management

Cymbidium prefers loose and fertile neutral or weakly acidic humus soil, which can be mixed with 65% humus soil, 20% net sand and 15% fine furnace ash. From the autumn equinox to the Winter Solstice, the magnolia should be applied once with solid fertilizer, with less nitrogen fertilizer and more phosphate and potash fertilizer. Eggshell powder and retting fish water is a good phosphate fertilizer, bran ash and soot are easily available potash. Nitrogen, phosphorus and potassium compound fertilizer can also be applied to promote the germination of more new plants and leaves. Fertilization must be appropriate, do not apply thick fertilizer and unfermented raw fertilizer, otherwise, it is easy to cause leaf tip scorch or rot. In winter, if the new leaves are spotted and the roots are yellow, it means that there is too much fertilization, while the narrow, thin and light color of the new leaves is a sign of lack of fertilizer.

two。 Watering

Due to the low amount of water evaporation in winter, the watering amount of Cymbidium decreased accordingly. The soil should not be too dry or too wet. Every time it is watered, it must be thoroughly watered, and some more should be watered after budding. Fermented bean cake water, fresh fish water and horseshoe water can be combined with watering every 20 days or so to combine watering and fertilization. Watering should be controlled when the room temperature is low to prevent the basin soil from being too wet, which will cause rotten root death, but can not make the basin soil too dry.

3. Heat preservation

The suitable temperature of Cymbidium in winter is 15 ℃ ~ 20 ℃, which should not be lower than 10 ℃. It should be placed in the sunny part of the room during the day so that it can be exposed to the sun and maintain its original color. The temperature should be kept at about 18 ℃ after scurrying, and the temperature difference between day and night should be about 10 ℃, otherwise the flower arrow will blossom if it does not reach a proper height, and it is easy to form a "sandwiched arrow". Therefore, when the outdoor temperature is lower than 10 ℃ at night, it should be moved indoors. When the indoor temperature is lower than 10 ℃, in addition to covering the surface of the basin soil with a layer of charcoal powder with a thickness of 1 cm, it should also be placed in an indoor sunny warm place. When the indoor temperature is very low, you can cover the flowerpot with a thin film to heat up, but the temperature in the cover should not exceed 25 ℃. If it exceeds, it should be ventilated and cooled down.

4. Adjust the light

Although the gentleman orchid likes the semi-overcast environment, the longer the sunshine in winter, the better. During flowering, strong light will shorten the flowering period, while weak light can prolong it. It likes to be warm and cool, and avoids severe cold and heat. It generally grows well at the temperature of 18 ℃ ~ 20 ℃, stops growing below 5 ℃, and does not suffer from more than 0 ℃. After the orchid enters the room, the light is limited and needs to be adjusted by manually moving the flowerpot. Therefore, to put the gentleman orchid in a place with good light (the family pot raises the gentleman early orchid can be placed in the sunny window, let it receive the sun light). Pay more attention to light, especially before flowering. Because the two rows of leaves of Cymbidium are opposite, if the light is in one position for a long time, it will make the leaves grow unevenly and affect the ornamental effect. therefore, the direction of the leaves should be paid attention to when adjusting the light, and the sunny side should be changed every 10 days or so. There are two ways to put the flowerpot indoors, one is to make the leaf parallel to the sunny window, the other is to make the leaf perpendicular to the sunny window, the effect of the latter is better than the former.

5. Measures to prolong flowering period

The florescence of Magnolia is mostly from December to March of the following year. The way to prolong the flowering period is to place the flowers in a place away from light when they are about to bloom, properly control watering, and keep the temperature at 8 ℃ ~ 12 ℃. In this way, the florescence can be prolonged by 10 to 20 days.

6. Timely pollination

Because of the low temperature in winter and spring, it is difficult to pollinate insects, so the most effective method is artificial pollination. In order to prevent the low seed setting rate and the degeneration of offspring, cross-pollination is generally used.

Conclusion: the above is about the maintenance methods of Magnolia in winter. I hope it will be helpful to everyone.
