How to water orchids in daily maintenance?

Hello! Orchid maintenance methods:

Orchids have surface ventilation as the first essence and Langui ventilation, unventilated orchids are easy to die, inside and outside the pot to ventilate, the orchid pot does not accumulate water, the planting material is loose and breathable, the orchid is placed in the breeze, ventilation can make the orchid breathe fresh air.

After the orchid grows for about 2 years, it is necessary to turn the pot in a timely manner, discard the seriously corrupted cultivation planting material, and replace it with a new cultivation planting material.

Orchids that have been raised for a long time, the leaves are luxuriant, the root system is developed, and the root system in the pot is intertwined, which affects the growth of orchids.

Orchid watering is a technical job, the pot can not be too dry, can not be too wet, to master the scale, so that the pot is long-term moist but not wet.

Orchids, like other flowers, need to supplement nitrogen, phosphorus and potassium, when the nutrients in the pot are insufficient, to use nitrogen, phosphorus and potassium fertilizers, such as urea, potassium dihydrogen phosphate, etc., to thin fertilizer diligently, the concentration is too high will produce fertilizer damage, generally diluted with water 1000 times before and after spraying leaves or irrigating roots.

Orchids in the late spring, summer and autumn should be shaded and sunscreened, shading can make the orchid less sick, the leaves look more beautiful, the cold winter should pay attention to anti-freezing and warm, prevent the orchid from freezing, the ambient temperature should not be lower than 3.

Control the humidity inside and outside the pot to avoid lack of water and dehydration of orchids, the environmental humidity should not be lower than 40%, and about 70% is the best for Liang Lijia, the leaves of too dry orchids are dull and easy to focus on.

If black spots are found on orchid leaves, sterilization should be carried out in time, diluted with carbendazim or methyl tobuzin and other fungicides mixed with water, spray leaves and irrigate roots, and use once every 7-10 days until the disease is contained. If insect pests are found, they should be killed in time, and targeted drugs should be used, and drugs should not be used indiscriminately.

Usually raise jujube to protect orchids, how to water the stool to cover the water and celery?

1. The ambient temperature of planting orchids should be suitable: orchids generally grow well in an environment of 25 to 30 degrees, but not all orchids are like this, and the temperature required by different varieties is different, and we need to depend on the situation;

2. Do a good job of watering: know certain skills when watering orchids, water more when they are vigorous, and less when they enter the dormant period; Flower pots are larger, plants are smaller and less watered, flower pots are smaller, plants are larger and should be watered more; Water more in dry and hot weather, and less water in rainy weather; In short, watering orchids depends on the weather, season, species, and other factors.

3. Choose the right pot and the right soil: When planting orchids, it is recommended that you choose a tile pot with a diameter of about 25 cm; You can prepare the soil yourself, and of course, you can also buy ready-made nutrient soil.

Orchids should be protected from rain

Orchids can be showered with light rain, but avoid mildew rain, showers, or continuous rain. In the mildew rainy season, it is especially necessary to do a good job of rain prevention. From late June to mid-September, showers are common.

If the rain is short and the rainfall is small, you should water more in the evening to let the heat in the pot be discharged, otherwise the orchid will be damaged, and even the roots will rot and die.

If the sun comes out again after a shower, shade should be taken in time to prevent the rise of heat on the ground and affect the growth of orchids. In the rainy season, it is the stage when orchids extract leaf buds, and if the potting soil is too warm, the leaf buds will not grow well or cause diseases. At this time, a small amount of plant ash can be sprinkled to adjust the moisture of the potting soil.

Light: When cultivated artificially, in order to adapt to its growth habits, it is not possible to bask in the sun, especially to avoid the scorching sun in summer and autumn. However, in early spring and deep winter, more sunlight should be basked, which has a great effect on orchid roots, leaf extraction, and pregnancy, and everything should be appropriate at any time.

Ventilation: Potted orchids should choose a well-ventilated site, which can promote strong roots and leaves, prevent bacteria and diseases, and show beautiful leaves and lovely. However, orchids are afraid of hot winds, strong winds, and dry winds, especially northwest winds in winter.

Watering: Moderate watering is the most important part of orchid maintenance. The water for raising orchids should be clean, preferably rainwater, snow water, and mountain stream water, but it is more difficult to do in plains or cities.

So is it possible to use tap water? Practice has proven that tap water that has been stored and treated for several days does not cause harm to orchids. Watering should be determined according to the degree of wetness of the soil, not the same regular watering, should be neither too dry, but not too wet, to slightly moisten.

Fertilization: To cultivate orchids, in addition to ensuring proper light, water and ventilation, an appropriate amount of fertilizer should be applied to grow vigorously and easily conceive flowers. Traditional fertilizer sources include toilet sand, bean po, etc.

Through practice, we believe that the application of sulfur-containing compound fertilizers is also effective. Orchid fertilization principle: should be diligent and light, avoid sudden and thick.

Disease prevention and insect treatment: orchid diseases mainly include anthracnose and white silk disease, and insect pests mainly include scale insects and ants. Orchid pests and diseases should be mainly prevented, and tobuzin or carbendazim diluted 800 times can be used at the same time, and dimethoate or pyrethroid pesticides can be infiltrated at the same time, and sprayed once every 10-15 days.

selection of humus soil; Top dressing mostly uses liquid fertilizer or foliar fertilizer; watering according to species, growth and local climate; Choose different temperatures for different seasons; Shading, orchid, also known as Chinese orchid, ground orchid, orchid, is a perennial root herbaceous flower of the genus Orchidaceae. Native to China, among which Yunnan, Guizhou, Sichuan and Tibet are widely distributed, it is a traditional precious flower in China and a famous flower in the world.

People have always regarded the orchid as a symbol of nobility and elegance, and together with plum, orchid, bamboo and chrysanthemum, they are called the "four gentlemen". Orchid is fragrant and elegant, and chrysanthemum, narcissus, calamus and called "flowers and plants four elegant", and orchid ranks first of the four elegant. The orchid is simple and unpretentious, the leaf color is evergreen, the leaf quality is soft and rigid, the flower is fragrant and clear, has a very high ornamental value, and is the treasure of the living room, the living room or the decorated study and the entrance hall.

Cultivated orchids. 1.Soil selection for orchid farming.

The soil for orchids should be mainly humus, mainly using humus or mountain forest humus. In the south, humus of origin is used, commonly known as orchid mud; It can also be used to artificially prepare loose, aerated and permeable culture soil with humus, vermiculite, perlite, etc. Generally, 8 parts of humus and 2 parts of river sand are mixed into culture soil, or 7 parts of humus, 2 parts of perlite, 1 part of river sand mixed with lush culture soil, or 6 parts of humus (peat), 3 parts of compost soil and 1 part of river sand are mixed into culture soil.

The above prepared culture soil is slightly acidic.

2.Fertilization methods for orchid farming.

Orchid fertilization, one is to apply basal fertilizer in the culture soil, and the other is to top dressing during the growth period. Top dressing mostly uses liquid fertilizer or foliar fertilizer, and the concentration should be lighter than that of other flowers. Orchids should be changed once a year to change the culture soil, and they can be less fertilized during the growth period, and attention should be paid to the timeliness.

Generally, in the growing season, you can apply about 15 thin cake fertilizer water that is fully rotted, or urea fertilizer water plus potassium dihydrogen phosphate fertilizer water, and apply it once every 15 20 days; Before flowering to flowering stage, potassium dihydrogen phosphate or plant ash water can be sprayed 2 or 3 times to the foliar surface to promote the development of roots, stems and flowers. Orchids are fleshy roots, and unrotted fertilizers should not be applied to avoid root rot.

Orchid cultivation method:

1. Apply thin fertilizer frequently.

Orchids like fertilizer, but not tolerant of thick fertilizer, when breeding potted orchids, need to be fertilized in accordance with the principle of thin fertilizer diligently, fertilizer can be applied every 3-4 weeks, you can choose diluted liquid fertilizer, or phosphorus and potassium thin fertilizer, to provide orchids with the nutrients needed for flowering, so that the flowers of the plant are more brilliant.

2. Control watering.

Orchids should avoid waterlogging, when breeding potted orchids, if watering too often, it will lead to rot of the root system of the plant, so that the orchid wilts and dies, and needs to be watered after the soil is completely dry, and during the rainy season, the potted orchid should be moved to a dry place indoors for maintenance.

3. Lighting conditions.

Orchids are not tolerant to strong light, but if they are placed in the shade for a long time, it will cause the plant to be difficult to flower, when cultivating potted orchids, you need to do shade measures for the plants in spring and summer, and in autumn and winter, you can place potted orchids in a sunny place to promote their healthy growth.

4. Maintenance method.

When maintaining potted orchids, it is necessary to place the plants in a ventilated environment to avoid poor growth of orchids, and to rotate the pots of orchids every half a month to make them receive light evenly, and to change the potting soil for orchids every 2-3 years, you can use sandy loam soil with good drainage.

1 Site selection It is required that the surrounding area is open, well-ventilated, and close to the water surface, with moist air and no soot pollution. In the southwest of the site, evergreen broad-leaved trees can be planted, and the canopy density should be about 0 7, which can reduce the afternoon sun exposure and adjust the humidity and temperature.

2 Watering It is advisable to use rainwater or spring water, not saline-alkaline 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 is less, and it is advisable to do 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.

3 Fertilization Planting orchid should be planted with cake fertilizer, with 4 parts of plant ash, 10 parts of bean cake, 10 parts of bone meal mixed well, put in the jar, add water several times, so that the bean cake soaks until it rises, and then cover and seal, after a year of decay, and then make 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.

4 Shade and protection from the cold Except in early spring and winter, it should be placed under an open-air canopy. The shade is required to be well ventilated, and the orchids can bask in more sunlight when they first come out of the house in March and April, and the shade time will gradually increase later. In winter, orchids should be moved indoors to protect against the cold, and the room temperature should be kept at 1c 2c.

In addition, orchids should also pay attention to frost protection after leaving the house in spring and before entering the house in autumn.

It's not advisable to use books, experience is to kill people, so let's do it yourself.

Shade and cold, see dry and wet, thin fertilizer applied frequently.
