What are the maintenance instructions for autumn and winter spring orchids and orchids, and how to d

First of all, it is necessary to have sufficient sunlight, and to irradiate it every day, you should wrap a layer of insulation film on the outside of the flower pot, so that you can take anti-freezing measures.

It should be moved indoors before the temperature drops below 10 degrees. Otherwise, it will cause frostbite to the rhizomes of the plant. Nutrients and water should be replenished regularly during the maintenance period. Occasional lighting.

1.Winter maintenance of orchids needs to be properly controlled, and it is best to ensure that the temperature is above 5 degrees, so that it can be better wintered.

3.You don't need too much watering, just water it when the soil is dry.

4.The water cannot be absorbed and is easy to dip into the roots.

5.Also, pay attention to ventilation issues.

6.Indoor maintenance should be ventilated on sunny days, and outdoor maintenance should be placed in a sheltered place.

Autumn is a dry and windy season, so it is necessary to water every 3 days in the way of spraying to improve the humidity of the growth environment, and carbendazim can be sprayed every other month to prevent pests and diseases.

1. Shade and sun protection

The weather in autumn is cooler, but the light at noon is still relatively strong, and Chunlan likes to grow in a semi-shady environment, so it is necessary to carry out shading and sunscreen when breeding at noon, and in early autumn, you can build a shade net above it, which can avoid being exposed to strong light, and if it is cultivated at noon, it is avoided from the light.

2. Increase air humidity

How to raise Chunlan in autumn also need to increase humidity, autumn is in a dry and windy season, and Chunlan likes to grow in a humid environment, at this time you need to increase the humidity of the air, you can spray watering, so that you can improve the air humidity while replenishing water, watering time can be carried out once in about 3 days to prevent the soil from drying out and dehydrating.

3. Apply phosphorus and potassium fertilizer

The cool temperature in autumn is also the season when the spring orchid grows vigorously, at this time you can apply an appropriate amount of phosphorus and potassium fertilizer to promote the growth of the plant, you can also add a small amount of organic fertilizer to supplement a variety of elements for the plant, and the use of nitrogen fertilizer needs to be reduced in autumn, otherwise it is easy to appear yellow leaves, and it can be applied every 40 days or so.

4. Spray carbendazim

Chunlanzi is prone to pests and diseases in autumn, so it is necessary to spray pesticides for prevention every day, and carbendazim can be sprayed every other month for disinfection and sterilization.

1. Soil: It likes soft, breathable, and well-permeable loam.

2. Light: It is suitable for growing under the scattering of half yang and half shade, the leaves will be dull if the light is too weak, the leaves will be very rough if the light is too strong, the temperature suitable for growth is 20 -30, and the temperature difference between day and night can not exceed 15.

3. Watering: It is recommended to give water every evening or early morning to keep the potting soil moist, and to give water once a week to make it thoroughly moist, and to water it once a day at noon.

4. Fertilization: pay attention to the acidity of the loam when fertilizing it to sell it, it is recommended to fertilize on sunny days, pay attention to the amount of fertilization, in the growth period, fertilize the leaves once every half a month, and water some alum fertilizer water in the loam every week.

1. Branching: before dividing it is necessary to control the watering, which can play a role in easy depotting, root softening, etc., when dividing the plant, you can choose a robust mother plant to divide the plant, do not plant immediately after the branching, you need to prevent drying in the shade until the root is white, and then apply the plant ash and plant it in the pot.

2. Sowing: After sterilizing the orchid seeds, plant them in an environment of 20 -25 to keep the ambient humidity up to about 70%, and they can germinate in about 3 months.

1. If you find that there are black spots on the leaf surface and spread irregularly, then it is Chunlan disease, and pesticides should be sprayed in time.

2. If you find that there are black spots on the leaf surface, which spread in a circle, it is anthrax, and you should shade the sun, avoid light, ventilate, and fertilize.

When I communicate with orchid friends, I often find such cases, a pot of orchids with strong buds has wilted because they have been moved indoors.

This gives many orchid friends a headache, because after autumn, the weather gradually cools down, and if the orchids are kept outside, they are worried that they will freeze and damage the buds. How can you move indoors at the right time to escape the cold?

In fact, the resistance of various orchids to cold is different, for example, large-leaved orchids such as Cymbidium grandiflora and Orchid blackberry have much weaker frost resistance. I once tested that at 5 degrees Celsius, Melan was frozen to death; And Chunlan and Huilan have nothing to do with minus 5---8 degrees Celsius for a short period of time.

Of course, this article still explains the spring orchid and the orchid, talks about how to manage the outdoor orchid after the autumn, and focuses on the wintering of the domesticated spring orchid seedlings in the mountains.

The autumn and winter mentioned here refers to late autumn to early winter, or the solar term is already winter. Every year around October 22 is frost and November 7 is the beginning of winter, do orchids still be kept outdoors during the more than a month when the frost falls to heavy snowfall? It is Lan You's most troubled thing.

Regarding the disadvantages of Chunlan and Huilan entering the house too early, I have encountered it myself several times, including my friends. The buds of Chunlan and Huilan need to be vernalized at low temperatures, although the theory of vernalization is not necessarily correct, but it seems that there is some truth to this statement.

I have done many frost-resistant experiments on wild orchids, with both success and failure. One of the worst was in the winter of 2017, and my Lan friends knew about it. In the winter of 2017, the climate here was harsh, with extreme low temperatures exceeding minus 9 degrees Celsius (maybe a little lower in the mountainous area).

When it snows heavily, orchids and buds are covered with snow at all and are covered with snow because "snow is covered" has a thermal insulation effect.

If the snow is cleared and the orchids are moved back indoors or in a shed, then there will be no problems with the orchids. The point is that in the days after the snow, when the sky clears and the snow begins to melt, the snow melts away under the sun during the day, and the snow water is poured into the pots, and by the evening the temperature drops and the water freezes. The next morning, when I picked up the orchid basin, it felt like I was holding an ice lump, and by this time the orchid had already formed ice cubes with the soil.

In order to make the experimental data more realistic and referenced, I have not moved this batch of orchids. Rao is so, these more than 20 pots of orchids were not wiped out in the end, and after sorting out in the spring of 2018, there are still half of the survivors. From this, it can also be seen that the frost resistance of Xiashan Chunlan and Huilan is good.

In this way, if the night temperature drops to minus 4-5 degrees Celsius in the short term, the temperature in the shed will rise as soon as the sun comes out during the day, so there is no danger of freezing in the potting soil. Only when the temperature is consistently below freezing during the day will the two ends of the film be sealed for insulation. Generally, this kind of insulation time will not exceed one month per year, and even in the insulated state, the temperature in the shed will not exceed 10 degrees Celsius.

In autumn, it is necessary to replenish more nutrients and water to have enough nutrients to cope with the following season, and to pay attention to the warm area in winter, otherwise it will cause frostbite. In addition, it should not be placed in a place with a heat source, otherwise it will cause the water to evaporate too quickly and cause wilting.

In winter, the orchids must be moved indoors to protect against the cold, and the room temperature can be maintained at 1 2, and you are heating in the northern bar.

Watering: It is advisable to use rainwater or spring water, not saline water, if you use tap water, you should leave the water for a few days before use. Watering depends on the temperature, the amount of watering in spring should be less, and more in summer; The rainy season is when the orchid extracts leaf buds, and the potting soil should be slightly dry; When the weather gets cooler in autumn, reduce the amount of watering and keep it moist.

In winter, it should be dry indoors, reduce the frequency of watering, and it is advisable to water at noon. Orchids can be drenched in light rain, but continuous rain or heavy rain is easy to rot hearts and leaves, so it is necessary to pay attention to rain. Fertilization:

It is advisable to use cake fertilizer for planting orchids, mix well with 4 parts of plant ash, 10 parts of bean cake and 10 parts of bone meal, put it in the jar, add water several times, make the bean cake soak until it rises, then cover and seal, after one year of decay, and then make it into dry grains. When using, it can be placed on the basin surface. If whole manure is used, it should also be decomposed for one year and mixed with water to dilute the filter residue.

Generally, fertilization begins in May, and fertilizer is stopped in the beginning of autumn, and thin fertilizer is mastered and applied more. Fertilization should be done in the evening, followed by 1 more water in the early morning of the next day.

Proper maintenance of spring orchids in winter, flowering becomes easy.
