How to grow orchids well, how to grow orchids

Home-grown orchids are generally potted in the following ways:

1. The potting soil is generally selected from the best mountain mud in the market, especially the black mountain mud is better. If homemade culture soil is used, it is necessary to add 1 3 and stir well. The pot is made of mud pots, and the holes in the bottom of the pot are larger.

After 1 or 2 years, switch to a purple sand pot, and it is best to have three or four holes in the bottom of the pot. When potting, first put a piece of green yarn on the hole at the bottom of the pot (to prevent ants from burrowing into the nest), then pad 2 3 pieces of pot pieces, put it on an oblique rest, and finally spread wood charcoal or cinder fragments, the thickness of which is 1 3 of the height of the pot. Next, spread a layer of crushed mud and mountain mud, then move the orchid into the pot and straighten it so that the roots are stretched.

At this time, water enough, place in a warm shaded place for 15 to 20 days, and then turn to daily care.

2. The environment in which potted orchids are placed should be selected. First, it should face south or east; second, the surrounding area is open and humid; Third, it should be padded with wooden frames or cement slabs, etc., and should not be placed on the ground.

3. When the temperature is high in summer, it is necessary to prevent it from being exposed to the scorching sun. Early spring, late autumn and winter, a certain amount of light is required. In the event of a thunderstorm or heavy rain, prevent the potting soil from getting too wet to avoid root rot. Potted orchids should be watered frequently, so that "not dry, not watered, after drying, watered, dry and wet".

4. Orchid fertilization should adopt the principle of thin fertilizer and diligent application, and avoid applying thick fertilizer or unfermented raw fertilizer.

5. Potted orchids should be cut off dead or diseased leaves at any time to keep the plant shape beautiful. Poorly growing branches and leaves should be removed in time to avoid consuming nutrients and affecting plant growth.

6. Potted orchids should pay attention to anti-freezing, move people indoors before freezing, and keep the room temperature at 1 2, so that they can safely overwinter.

How to divide orchids The propagation of orchids adopts the division method, when there are too many plants in the pot, too dense, affecting further growth, you can divide the plants. Dividing is suitable in spring and autumn, every 2 3 years or 3 4 years. The dividing plant should be carried out when the potting soil is slightly dry, first dig out the whole plant from the pot, remove the soil between the roots, wash and dry it with water for 2 3 hours, cut off the rotten roots, cut it from the false bulb with a sharp knife, gently pat loose the "root net", straighten the roots, follow the root lines, and then cut or break it, do not hurt the young roots.

When dividing plants, it is generally planted in a pot from 3 to 5 clusters, and is planted in a triangular or mesh shape.

How to buy Before and after the Spring Festival, there are often orchids in the flower market**, at this time the spring orchid has buds, and some of the roots are rooted in the green cloud grass, and there are dew roots. When purchasing, it is better to choose those with strong green leaf luster, fresh and strong fleshy roots, and straight buds. Such orchids have strong vitality and are easy to grow and develop after being planted in pots, and can bloom.

If the leaves are yellow, the roots are shriveled, and the flower buds are wilted, the survival rate is low, or the flowers will not bloom after planting.

Prepare the utensils for planting orchids, and go to the mountains to take some humus or outer skin soil (which should be soft) to contain a lot of humus. Loose. The neutral acidic soil with better drainage pipes is appropriate, and the pH value is generally up and down.

The main stem of the orchid to be planted is embedded in the core part of the pot, and the moderate process is supported with support. The wire strap is fixed to prevent damage to the roots. Gently clamp the planting material slightly from both sides.

Place the orchid on a south-facing balcony or courtyard (it does not have to be placed on a north-facing balcony or in a room for a long time). In spring and winter, let it bask in the sun more, and in summer and autumn, when people feel uncomfortable in the sun, orchids are not allowed to be exposed to the sun immediately. No need to fertilize.

When orchid watering is prohibited, you can lift the pot surface planting material two or three centimeters deep, and do it like this, and water it immediately; If it is not dry, pour it after another day or two. When watering, the whole pot has been watered, and it has been watered for a while, so that all the planting materials can "eat" the water.

In February, the ghost wind "yellow leaves and yellow retreat are routine, and the dead branches and leaves can be cut off. Orchids can be drizzled, but avoid mildew rain. Heavy rain or continuous rain, otherwise it is easy to get angry.

Rotten leaves. When there is a lot of precipitation, a small amount of grass ash can be sprinkled moderately. When the average winter temperature in northern China is close to 3, pay attention to moving orchids into the room to prevent cold damage; In the south of Fujian Province, orchids can safely spend the winter outdoors in winter.

When shaping orchids, yellow, broken leaves and diseased leaves should be often cut. Facilitate natural ventilation. Precious orchids, such as too many buds, only strong buds, 1-2 buds per pot is appropriate.

Spring orchid blooms for half a month after cutting, precious orchids should be cut in 7 days, spring buds grow and develop strongly, and create a stronger next year. When the last flower on the inflorescence of the summer orchid is open to the public for a week, it is cut 3 cm from the pot surface.

Bonsai soil should generally be sterilized (can also be exposed to the sun) to prevent the occurrence of diseases. Orchids are prone to white silk disease in rainy and high temperature seasons, a small amount can be brushed off with a wet rag, and the pot amount can be used 500-800 times agricultural streptomycin or tobuzin, sprayed every 7-10 days. The insect pests are mostly aphids (alias "lice"), and they are sprayed once a week with 1% dimethoate and 25% imithion emulsifiable concentrate 1000 times during the egging period.

It is advisable to treat both the symptoms and the root causes, and the pots and bowls should be sparse and moderate, and how much should be placed, so as to improve the air permeability and natural ventilation and reduce the occurrence of diseases.

Orchids raised at home should be planted in pots, pay attention to watering, regular fertilization, and loosen the soil, so that they will grow well.

Choose pots with good air permeability, choose organic soil, ventilate more, and fertilize frequently to ensure the amount of watering.

It can be placed in some sunny places, to be ventilated frequently, and to loosen some soil frequently. Pay attention to ventilation. Try not to overeat.

It is necessary to water in time, to ensure the moisture of the soil, and to remove problematic plants in time. It is necessary to pay attention to the depth of planting, but also to ensure the fertility of the soil.

First of all. You have to prepare a flower pot, as for the material, there are no special requirements, of course I use the most plastic pots and purple clay pots. The advantage of the purple sand pot is that it is beautiful, and the orchids planted are not easy to be blown down by the wind, and the same disadvantage is that it is inconvenient to move, and it is easy to break.

Therefore, I use plastic flower pots the most, and the tall pots commonly used for planting orchids must have a bottom hole to drain water, and it is better to have a waist hole. If the height of the pot is not very large, it does not hurt not to have a waist hole (the plastic flower pot in the picture above is without a waist hole).

Step 2. It is to choose a robust orchid seedling, there are many leaves of the downhill orchid that are not beautiful enough, don't be too strong about this, the really good-looking is the domesticated orchid seedling. Depending on the time of digging, the root system of the orchid may not be perfect, but as long as it is planted properly, it will not affect its survival.

The key point of selecting the lower mountain orchid is that the reed head should be fresh and powerful, the leaf width and thickness of the new seedlings should be stronger than the old seedlings, and each plant should have at least two or more new seedlings, so that the orchid seedlings are easy to rejuvenate.

Step 3. To prepare the planting material, the most suitable planting material for planting Xiashan orchid must be made of humus soil (especially the original mountain soil is the best). As for other orchid species, there are many planting materials to choose from, so I won't go into detail here.

I suggest that the planting material for the lower mountain orchid is to use decaying bark (not artificially fermented, but naturally decaying) plus humus and some weathered stones. As much as possible to mimic the structure of the soil in the wild, such soil orchids are easy to survive.

Step 4. Planting and pre-planting treatment, orchids need to be pruned before planting, pruning the dead and rotten roots and residual leaves, so that the orchid can be lightly potted. Of course, if there are seedlings or reeds that are too old, there is no need to put them into the pot, and most of these old seedlings will become a burden in the end.

It is not recommended to vigorously disinfect the orchid before potting, the orchid growth environment is multi-strained, and excessive sterilization and disinfection are not good. Only by cultivating orchid probiotics, allowing it to inhibit the harmful bacteria in the potting soil, and achieve the coordination of the flora in the small environment, is the most ideal orchid growth environment.

Step 5. Foliar fertilizer can be sprayed after a week for newly planted orchids, of course, the concentration is lighter than the conventional dosage, about two-thirds of the conventional dosage. After 50 days, it can be determined whether it needs to be fertilized according to the seedling condition, and if it is planted with the humus soil of the original mountain, there will be no problem if you do not fertilize it for a year.

Follow a sentence when fertilizing: 5 nitrogen, 8 phosphorus and potassium, apply organic in October. May (referring to the end of summer and early summer) is the season for orchid seedlings to grow, and fertilization can be partial nitrogen fertilizer to promote orchid seedlings to grow into strong seedlings quickly; August is the bud pregnancy period of orchids, and nitrogen fertilizer needs to be controlled, otherwise it may cause orchid plants to grow and affect the pregnancy buds.

After autumn, the fertilization is mainly organic fertilizer, and I use rotted tea withering (solid residue after oil extraction from Camellia oleifera seeds).

1. The pot is preferably small in mouth, deep in pot and large in bottom hole, and the thickness of the culture soil is about 3 5 cm, and the base fertilizer is generally not added.

2. Then put the orchid into the pot, cover it tightly with soil, and then use your fingers to compact it around the pot.

3. The first watering adopts the pot sitting method, so that the pot absorbs enough water, and the pot orchid is placed in the shade for about half a month to 1 month.

4. During this time, watering must be controlled, not too wet, and placed in half shade and half sun, ventilated and ventilated, and can shine to the sun in the morning.

5. The new orchid pot, the pot soil is too fat, often can not survive, even if it can survive, it rarely blooms, the leaf buds are new, you can use a small amount of light fertilizer to apply several times, the fertilizer must be rotten, can not be used without rotting, avoid using human feces.

6. Orchids are eight points dry, two points of moisture are the best, and the flowering period and the leaf bud stage should be watered less.

Orchids are afraid of the sun and cold, and they can neither be water-based nor too dry. It's a lot of trouble.

1. Put it in a place with good ventilation indoors, no sunlight but good visible light.

2. After the bottom of the flower pot is covered with broken tiles, the bottom can be paved with ceramsite to ensure that the limbs hold their good air permeability. Ke Rub Min uses dried moss, lichen, etc. as the upper layer of bedding to lock in moisture and keep warm.

3. While ensuring regular watering, if the ceramsite feels dry, you can pour water on the tray to keep its roots moist from the evaporation of the water that has returned to the moisture.

4. The indoor air should maintain a certain humidity, and you can use a watering can to spray the flower pot and around the flowers regularly.

5. "Orchid Cultivation" contains: "Spring does not come out, summer does not day, autumn does not dry, winter does not get wet", this is the summary of China's experience in raising orchids.

Finally, make sure that the temperature of the place where the flowers are located is too high and the ventilation is poor. Several major pests and diseases of orchids are related to these two items. Hope!

Orchids like to be cool in summer, warm in winter, soil is qualitative of hail and lack of fertilizer, it is best to mix it with burned cinders and a little sand, watering reputation should be appropriate, watering after the epidermis soil is white, and then watering, not suitable for direct sunlight.
