All adopt traditional orchid cultivation methods.

Orchid cultivation, this orchid cultivation method has low requirements on the environment, and the balcony,

Go down, along the corridor, in the shade. Generally use a pot.

Pottery pots, wooden pots, plastic pots, etc. , especially

In the shape of ...

The pottery basin is ideal, with good air permeability and strong water absorption, which is very suitable.

Raise orchids. The basin requires a drain hole at the bottom and a drain hole at the side.

If it can't meet the requirements, it can be handled appropriately. The size of the pot depends on the size of the orchid plant, which can not be underestimated.

Basins and weaknesses

The choice of potted materials is

The key to success. Ordinary dry cultivation

Most of them are taken from deep mountains and valleys.

vegetatively

, and then add the right amount of bark and particles.

、

Particles, etc. After proper improvement, this planting material

Rich in content, slightly acidic, loose and breathable, it is very suitable for orchids to be dried or steam sterilized before they come out of the pot, and the screening is different.

Divided into coarse particles, medium particles and fine particles, and stored separately. Powdered broken soil should be discarded. When serving, crush the bottom of the basin first.

As a drainage layer, foam blocks mainly play the role of drainage and ventilation, accounting for about one-fifth of the height of the basin; Then a layer of coarse-grained plant material is added, and a small amount of fermented plant material can also be added.

Equal work of grain

, this layer is

, mainly plays the role of water filtration, ventilation and nutrition, accounting for about a quarter of the height of the basin. Carefully put the trimmed, disinfected and dried orchids into the orchid pot and straighten them.

Keep the orchid plant in the ideal cultivation position with your left hand, and gradually add the medium planting materials with your right hand. When the planting materials are added to a certain amount, gently lift the orchid plant, gently shake the orchid, and then gently compact it with your hands to make it

Full contact with plant materials to prevent

There is a gap between them to create empty roots, and then continue to add planting materials.

Shake the basin again to make the plant materials dense. This layer is the nutrient layer, which is the main place for orchids to grow and absorb nutrients. Its thickness accounts for about half of the height of the basin. Of course, its thickness should be adjusted according to different orchid varieties. Generally, the thickness of orchids with thicker roots can be appropriately increased, and the thickness of orchids with thinner roots can be appropriately reduced. Then, add fine planting materials until they are covered.

Two-thirds of the position can be compacted gently to make it appear.

Shape, this layer is

. In order to prevent tiny plants from being washed away by water or splashing mud when watering.

You should also add a suitable water-retaining protective layer on this layer. Generally, this layer is composed of coarse-grained hard plants, such as grains.

、

、

, even

Wait, Jiangsu and Zhejiang provinces mostly use transplantation.

In Yunnan, it is used a lot.

First, soak the nail plate 1000 times solution for disinfection, then squeeze out the water by hand, spread it evenly on the basin surface, and then pour it on.

Keeping a cool and ventilated place is an important part of dry orchid cultivation. Orchids are fleshy roots, no.

Symbiosis with cyanobacteria, relying on cyanobacteria

Absorb nutrients for the growth of orchids; Orchids are the root of orchids.

Officer, you need to make a phone call

Qi, meanwhile, cyanobacteria

Its growth and proliferation also need oxygen, so plant materials must be breathable to ensure the supply of oxygen. If there is too much water and the oxygen content in plant substances is low, the respiration of orchid roots will be blocked, orchids will not grow normally, and it is easy to produce empty roots and rotten roots. Due to the adoption of dry orchid cultivation

Although handled properly, it

It is still strong, with poor permeability and heavy fertilizer. With the increase of use time, the planting materials will harden and acidify, such as improper watering time, which will easily cover the roots of orchids and affect their growth. The ancients emphasized that "Lan Xirun is afraid of wet, but likes dry and is afraid of dry", which is generally a planting material.

75 ~ 40% is the most suitable. If it is less than 40%, it will be watered. If it is higher than 75%, it is easy to damage the roots of orchids after a long time. But when to water and when not to water depends on the environment, the plants used, the size of the flowerpot and the air.

The growth of orchids depends on their strength. How to determine the amount of water in the basin? After groping, Lan Jia has the following methods: 1,

. According to the condition of orchid leaf surface and the wet and dry condition of orchid flowerpot surface, if orchid leaf surface has

The plant material on the surface of the basin has been thoroughly dried. When the plant material on the surface is about 5cm dry, it means that the plant material is short of water and should be watered. 2. Weighing method. Its principle is to fully pour the experimental plant material until it is leached without water.

100%, fully drying plant materials.

Weigh about 20% respectively, and get the corresponding water content per unit weight through calculation, so as to judge the water content in orchid planting materials. This method is more accurate in theory, but there will be some deviations in practical application, which is not easy to operate. Step 3 insert

. Just insert a bamboo stick carefully in the appropriate position in the orchid pot and pull it out after about an hour. According to the humidity of bamboo sticks, the water content in the planting materials of orchid pots can be judged. Now some people use electronic hygrometer instead of small bamboo sticks. This method is more effective and easy to master, but the disadvantage is that it is easy to hurt the orchid root. 4, knocking on the basin to listen to the sound method. Pick up a pot of orchids, put it to your ear and tap the edge of the pot with your hand. If the sound is dull, it means that there is still a lot of water in the plant material. If the sound is crisp, it means it's time to water. This method requires some experience, which is not easy for beginners to master. 5. Control method. Fill an empty pot with the same plant material, then water it with the blue pot and put it together at the same time. When checking, you can compare the water content of plant materials in the blue basin by inserting your finger into the control basin for checking. Of course, some experienced Lanjia have their own methods to judge the water content of plant materials through years of exploration. Generally, they only need to check a little to know the water content, which can be described as "knowing fairly well", but watering is another matter.

, pouring will be done by pouring. During the growth of orchids, orchids and orchids constantly absorb oxygen, exhale carbon dioxide, and at the same time discharge some metabolic wastes. Watering can regulate the air in plant matter, discharge the original dirty gas, replace it with fresh air, and wash away and discharge metabolic waste. In addition, it can kill insects and eggs and hinder them.

Generally speaking, there is less watering in winter, because orchids are dormant in winter, and the demand for water is not great, so water can be watered once every half month to one month. In spring, the temperature is getting higher, the air is dry, and orchids sprout new buds. The water supply can be appropriately increased to promote the germination and growth of new buds, usually once a week. From midsummer to early autumn,

The temperature is high, orchids grow fast, and there is a great demand for water. Give water every 3-5 days.

In early winter, the temperature difference between morning and evening is large and the air is dry. Give water every seven weeks. In rainy days, the water supply can be appropriately reduced, and repeated watering is generally adopted.

A small amount of water is supplied along the spiral of the basin for many times until it is thoroughly poured, but only one basin can be soaked at a time, and then another basin is soaked with clear water after pouring out, so as to prevent diseases.

. Because plant materials are rich in nutrients, and orchids grow slowly, the demand for nutrients is not as great as that of other plants. Therefore, the fertilizer used for the cultivation of dried orchids is generally light and thin, about once a month to prevent fertilizer injury. Weak orchids and diseased orchids had better not be fertilized. After being used for a period of time, the permeability and PH value of plant materials decrease, so it should be replaced to prevent its hardening and acidification from affecting the growth of orchids. In a word, dry cultivation of orchids is a simple, convenient, practical and economical method, which does not require too much energy and cost, and is especially suitable for orchid friends with limited time and energy, as long as watering is solved.

The title can make orchids grow well, flowers flourish, colors are bright and fragrance is rich, which is a better popular orchid cultivation method. Second, wet orchid cultivation Wet orchid cultivation is developed on the basis of summarizing the advantages and disadvantages of dry orchid cultivation. Its biggest feature is "wet", which requires relatively high environment and planting materials. When using wet orchid cultivation, we should pay attention to the following six points: 1) Compared with dry orchid cultivation, wet orchid cultivation requires higher environment, especially proper control of temperature and humidity. If the temperature and humidity are too low, it will lose the meaning of wet cultivation of orchids. Therefore, it is best to use a fully enclosed or semi-enclosed ceiling with ventilation and mining.

Well, try to avoid all kinds.

, for example

, dust and so on. Common methods to increase humidity are: making the foundation of orchid shed.

, ground laying

, sand,

(wooden) bench

Water retaining layer, or placing water tray, building pool, etc. , the wall adopts

Glass,

board

Water spraying and humidification, etc. The problems that should be paid attention to in the construction of orchid shed are described in detail in "Four Levels of Orchard shed Construction". Interested You Lan can refer to 2) Choosing pots and tools.

Pots, wooden pots and plastic pots are all ideal pots for cultivating orchids, especially plastic pots, which have recently become the main pot species for wet cultivation because of their low price, portability and durability.

Most of the south and Sichuan have received strict support.

、

Mainly because of this

The system is developed, the root diameter is mostly above 0.4cm and the root length is above 20cm, so it is appropriate to choose pots.

Plastic basin, convenient

Growth and development, at the same time, due to the use of wet cultivation, the selected orchid pot should be thin and small. The so-called thinness here means that potted orchids should be slender, which is different from traditional dry orchids.

Small is relative. The orchid pot is the space where the roots grow. Excessive blue flowerpots will affect air permeability, heat accumulation,

It is easy to cause water accumulation and root rot, increase the difficulty of daily management and waste planting materials. If it is too small, it will limit the growth space of Cymbidium hybridum roots, and the Cymbidium hybridum roots will compete for space to squeeze the planting materials, which will lead to the hardening of the planting materials and weaken the activity of cyanobacteria. At the same time, too few planting materials will provide insufficient nutrients, which is not conducive to the growth of cymbidium root system, and it should be decided according to the specific situation. So how to judge whether the blue flowerpot is suitable? You can use blue plants.

For reference, it can make most orchids

Stretching naturally in the basin,

The position in the basin is slightly lower than the basin surface. Of course, if orchids are particularly tall or have too many seedlings, pots should be used appropriately. about

、

For orchids with thin roots, the height of the orchid pot can be appropriately reduced or the thickness of the filter layer at the bottom of the pot can be increased. 3) Selection and preparation of plant materials The plant materials selected for wet cultivation of orchids are mainly coarse plant materials, and the preparation should strive to be "loose and breathable,

Moisturize. "The author's approximate proportion is: rotten leaves 50%, granular bark 15%, granular.

15%,

Granular 10%, granular

7%, snake wood 3%. The specific preparation method comprises: putting Quercus acutissima leaves into a container.

Compaction, pouring boiling water above 90℃, flooding oak leaves, covering, soaking for one month, pouring off water, putting the soaked oak leaves into plastic bags, tying the mouths, and exposing them to the sun.

For about three months, after it turns black and gives off a clear fragrance, it is taken out and sieved to remove the broken leaf powder, which is called rotten leaves. Burned granular soil with a diameter of about 0.5 ~ 1 cm should be used and soaked for about a week before use. Bark particles are about 1 ~ 2 cm in diameter and should be fermented before use.

Skin,

Better wait. Snake wood should be cut into small pieces about 2-5 cm long and soaked for a week before use. will

Keywords burning granular soil, bark particles,

Mixing uniformly in proportion, bagging, and sterilizing. This plant material is slightly acidic and contains certain nutrients and what orchids need.

, very suitable for lotus petals,

Cultivation, etc.

Mainly plays the role of regulating planting materials.

Provide orchids with what they need.

Because it is easy to be crushed and hardened, the dosage should not be too much, and it needs to be cultured in a pot. The layered cultivation method is adopted, specifically: a proper amount of foam plastic blocks are placed on the bottom of the basin as the drainage layer, and a small amount of plant materials prepared according to the above method are added as the drainage layer.

At the same time, a small amount of fermentation can be added.

Grain, this layer accounts for about a quarter of the height of the basin, and a small amount is added after compaction.

Particles, forming a thin layer, and then put the sterilized orchid into a pot, hold the orchid with your left hand, and straighten the roots of the orchid with your right hand.

Flush with the mouth of the basin, then add the plant material, gently press it by hand while adding it, so that the root of the orchid can fully contact the plant material. When it is about half, add a small amount of laterite particles to form a thin layer, and then add plant materials until it is close to false.

Add a small amount of laterite particles to form a thin layer, and then continue to add plant materials to expose the fake slightly.

It is recommended to gently press the planting materials by hand and manage them as follows.

Shape, and then sprinkle the remaining red soil particles around pseudobulb, a small amount.

Cover red soil, soak and disinfect red soil.

Squeeze out the water, spread it evenly on the basin surface, and pour it in.

Do it. Of course, the above is only for the cloud.

As for the commonly used planting materials, such as fairy soil and other planting materials, you can refer to them. Plant materials are perishable or finely divided after being used for a period of time, and should be replaced in time. 4) Water management The "wet" of wet orchid cultivation refers to

Management, which has three meanings: first, appropriate increase.

The second is to increase the water supply and the third is to increase the frequency of water supply. Because the pots used for wet cultivation of orchids are small, the plant materials have good air permeability, strong drainage, rapid evaporation of water, and the plant materials are not easy to accumulate water, so water management is advocated.

Management,

It should be around 70%; When watering, water it thoroughly. Under normal circumstances, the plants in the basin are always wet; Increasing the frequency of watering, the advantages of high watering frequency are as follows: first, it can drive the airflow in plant materials to move, replace the air in plant materials, and at the same time, oxygen in water will be released, so that the air in plant materials is rich in oxygen and supplied to orchids. Second, it can take away the metabolic waste produced by blue roots and auricularia, which is more conducive to the growth of blue roots and the activities of auricularia. Third, it can make planting materials.

Accelerate the transformation, provide rich nutrition for orchids, and prevent the heat and waste generated by the fermentation of plant materials from harming the roots of orchids. Fourth, fresh water has high activity and contains certain nutrients and

Is more beneficial to plant absorption and utilization. When wet management is adopted, the requirements for water quality should be

The method is relatively high. Fresh rain is better for watering orchids, but one is difficult to collect and the other is in some places.

Because the rain may be polluted, tap water is mostly used now, but because tap water contains chlorine, it is too high for wet orchids to be used directly for a long time.

Will affect the growth of orchids, chlorine will occur.

Produced

Very powerful

, will inhibit the activity of cyanobacteria, so it is best to leave it for about 12 hours, and then use it after most chlorine gas escapes; If adopted,

, because

The middle calcium content is high, which is easy to form on the basin surface and orchid roots after long-term use.

Sediments affect the growth of orchids, so add a small amount.

ensconce

. For water stored for too long, due to

The physical activity of water is greatly reduced by chain polymerization, which is not conducive to the absorption and utilization of orchids. Fresh water should be used as much as possible. of course，

Management does not mean watering irregularly and without restraint. Generally speaking, we should master a principle: water more in hot days, less in cold days, more in sunny days, less in rainy days, more in small pots, less in large pots, more in healthy seedlings, less in sick seedlings, more in dry air and less in humid air. Water 1-2 times a day from early spring to early summer, after sunrise in the morning and before sunset in the evening; Midsummer solstice

, you can fill it 2-3 times a day, three times in the morning, middle and evening; In late autumn and early winter, water 1 time in 2-3 days, at sunrise in the morning or sunset in the evening; In the dead of winter, because orchids are dormant, they need less water and can be watered 1 time a week.

At noon in lang restaurant. When watering, it must be thoroughly watered, and it is forbidden to water half of it, so as to prevent orchids from appearing empty roots due to excessive drying of planting materials and affecting their growth. When watering, you should also pay attention to prevent water from splashing on the heart of leaves. If you accidentally spill it, suck it off with cotton paper in time. Strengthen ventilation and lighting after watering. Because the cultivation of wet orchids adopts heavy water management, it is bound to cause some nutrients in plant materials to lose with water, so timely fertilization is extremely important. Generally speaking, it should be light, thin and diligent. The author adopts self-control

The method is as follows: soak rapeseed cake, wormwood, etc. They are,

For more than one year, add clean water to water orchids at the ratio of 1: 10, twice a week. Combined use at the same time

There are about 2000 times.

and

The solution should be sprayed separately, and it is better to apply it in the morning and evening when the fine droplets formed on the leaf surface do not flow into the leaf center. If it accidentally flows into the heart of the leaf, it should also be carefully sucked off with a piece of paper. If you don't have the conditions to make your own organic fertilizer, or it's too much trouble to do it yourself, you can directly apply the commercially available blue fertilizer, such as magic fertilizer, high extraction, blue mushroom king and so on. Whether it is self-made blue fertilizer or commercially available blue fertilizer, it is best to do experiments with common grass before application to know whether it is harmful and the appropriate application concentration to prevent accidents. 5) Lighting and

Due to the heavy water management, and the water temperature is usually lower than the room temperature in spring, summer and autumn, it is easy to cause the temperature in the orchid pot to be too low, which will affect the growth of orchids. Therefore, on the one hand, it is necessary to require the water temperature not to be too low, which may easily lead to a sudden drop in basin temperature and physiological dehydration of orchids. But the water temperature is too high and it is easy to cause blue pot.

The muggy and stuffy seedlings can generally be slightly lower than the ambient temperature. On the other hand, it is necessary to appropriately increase the amount of light to meet the temperature requirements of orchids. Sunlight is the driving force of plant growth. "

Orchid leaves rely on sunlight to produce nutrients through photosynthesis, which not only meets their own needs, but also provides conditions for the germination of new plants and the reproduction of future generations. At the same time, proper light can enhance the growth of plants.

Kill harmful bacteria and promote the normal germination of orchids.

、

, normal flowering, and can promote leaf art,

The evolution of. Light can also increase the temperature in the basin and promote the temperature increase in the basin.

This decomposition and transformation provide necessary nutrients for the growth of orchids. Ventilation is also an important condition for orchid growth. Especially wet orchids, because of the high temperature and humidity, all kinds of germs are easy to breed, which may be caused by a little carelessness when watering.

If you don't pay attention to ventilation, stagnant water will easily breed diseases, and the air flow can not only inhibit the growth of harmful bacteria, but also promote the air flow in the plant materials in the basin and take it away.

The indoor humidity is high, and there are exhaust gas and miscellaneous gas around it, which are not conducive to the growth of orchids. It is necessary to strengthen ventilation. Ventilation is generally used.

Even better.

For example, because the south wind blows all the year round, ventilation window can be set up in the south and north of Peng Lan, which can achieve satisfactory results; If there is no window opening condition, or

When the actual needs cannot be met, use.

Artificial ventilation is also a good choice.

& lt As mentioned above, dry cultivation of orchids is easy to cause hardening and acidification of planting materials, resulting in various diseases, especially root diseases such as

、

and

Mainly. The wet cultivation of orchids, due to the high humidity of the local environment, is easy to cause the reproduction of various harmful bacteria and endanger orchids in midsummer. Common diseases are as follows

、

、

By analogy, light will affect the growth of orchids, and heavy will lead to the death of orchids. Therefore, the prevention and control of pests and diseases is particularly important. The first is prevention. pay attention to

Clean, remove all kinds of garbage in time and spray regularly.

such as

、

Disinfect the surrounding environment and use basin utensils.

Potassium solution should be strictly disinfected, and plant materials should be disinfected with high-temperature steam before use. If the conditions are not met, plant materials can also be disinfected by sun exposure. Orchids in normal management and protection should be sprayed regularly.

、

、

、

Liquid drugs such as manganese and zinc are used for prevention. The second is governance. Yes, it happened.

、

、

Orchid plants with leaf diseases, such as leaf diseases, are generally harmless to orchids and can be used directly.

、

、

Such as spraying, and pay attention to timely cut off the patient's site and

; Yes, it happened.

、

、

、

Orchids with serious diseases, etc. , should be resolutely isolated, turn over in time, and cut off the diseased orchid with a sharp knife. At the same time, healthy orchids connected with diseased orchids may also be infected with pathogens. They should also be cut and burned, with a knife after each cut.

Potassium solution or alcohol disinfection. Divide the remaining healthy orchids according to the distance from the diseased orchids, rinse them repeatedly with clear water, and put them in about 500 ~ 1000 times (slightly higher than the usual application concentration)

Manganese and zinc,

、

Such as potions (different choices according to different diseases.

) for half an hour, take it out and hang it in a ventilated place to dry. If the orchid is close to the diseased orchid, it can be soaked and disinfected again, dried and sprinkled with a small amount of dry powder at the incision. You can also wet the area around pseudobulb with a brush, sprinkle a small amount of dry powder, and then replace it with fresh plant materials, which will be exposed by pseudobulb to facilitate the observation, treatment and recovery of orchids. Water the orchids around.

Manganese and zinc,

、

Equivalent to liquid medicine

But don't spray it directly on orchid plants, then put it in a ventilated and dry place, dry it, and manage it after one week. To prevent infection

Orchids must be resolutely burned; In principle, orchids infected with epidemic diseases should also be burned because they are difficult to treat and highly contagious. If it is a rare orchid, the above methods can be used for symptomatic treatment, but strict isolation measures should be taken to prevent infection. There is a misunderstanding here. Some You Lan like to use it after turning over the basin.

、

be like

If it is a normal orchid, disinfection is not bad, but long-term use will produce germs.

, greatly reducing the curative effect, so we should take turns to use several drugs with different components and strictly control the concentration to avoid too high or too low concentration. For example, it is used to disinfect orchid plants suffering from the above-mentioned serious diseases because thiophanate-methyl,

For this disease

Weak inhibition, unsatisfactory disinfection effect and easy recurrence.

, causing greater losses, you should suit the remedy to the case and try to choose drugs with better effects on this disease, such as

Select employment/use

Choose streptomycin,

Zinc manganese formate is selected,

The third option is to kill insects in time. most

, for example

、

、

、

Wait, it not only consumes the nutrition of orchids, but also makes them grow.

, immunity is reduced, but also make orchids produce wounds, guide.

Invasion easily leads to disease;

、

Others eat the leaves and buds of orchids,

Its harm should not be underestimated. For this pest, you can use

、

There are also tianding and so on. , you can also use.

When applied to root control, the effect is good, but attention should be paid to it.

, in case of human and animal poisoning, avoid the use of pesticides and other spray to kill; Although ants rarely directly harm orchids, they often do harm to orchids.

、

Provide conditions for the occurrence of harm, but also pay attention to disinfection; Mosquito,

You can use the yellow board.

. At the same time, we should pay attention to constantly learning and accumulating some knowledge of orchid disease prevention and control, and ask for advice humbly in order to continuously improve our own orchid disease prevention and control level. In a word, wet management is easy to stimulate the germination and growth of orchids because of sufficient water supply, high water content and relatively low substance concentration, and because of its relatively good growth environment, this method can effectively improve orchid plants.

Promote the growth and development of orchids and improve the cultivation efficiency of orchids. However, this method is only applicable to You Lan, which is not too busy at ordinary times and has more free time.
