Why do orchids have to dry their roots when they are planted?

In the process of planting orchids, how can this process be operated well? Here are a few steps to explain.

a) Drying roots:

1. Depotting and cleaning, 2. Cutting off rotten roots and excessively long roots, 3. In case of empty root rot, only the reed head part is left, retain the hard stem of the root system, and clean up the rotten root flesh.

4. Place it in a place that can shelter from the shade, ventilate and block the rain, 5. When placed, the roots should be facing the sky, and the leaves should be hung upside down towards the ground to avoid water accumulation in the center of the leaves.

6. When the root is white and soft and wilted, spray it once or twice with disinfection and sterilization water solution to make the root appear full of water, and the leaves should also be sprayed, so that the roots and leaves of the whole orchid are sprayed with the solution, and the purpose of drying the roots is basically achieved. It is slow to operate on rainy days, and sunny weather is generally chosen to change the material and pot.

Note: It is best not to put it directly on the ground, if it is placed flat on the ground, the water in the heart of the leaf is not easy to flow out, and it is necessary to turn it over from time to time.

Benefits: After the root system of the orchid becomes white and soft after the roots are dried, it can be arbitrarily arranged when planting, pulled to an ideal state, not easy to break, easy to pot, and can be better operated when spraying fungicides and insecticides.

Because orchids are difficult to plant and difficult to adapt to the new soil environment, drying the roots can quickly dry the excess water of the orchid roots, which is conducive to the cultivation and planting of orchids.

Why do orchids have to be dried before they can be planted?

A few plastic buckets (empty buckets after the oil at home is used up) is a little larger than the blue basin, and the depth is 4 5 of the blue basin, so prepare a few more.

1. Soak it in the first bucket of water, and take the basin surface as the degree that there is no water. About 4 5 of the height of the pot. Take a dip and raise it right away.

2. Soak in the second bucket of fertilizer water (or potion) for 3-5 minutes to let the planting material "eat". The depth of immersion is about 2 3 of the height of the pot, and 3 cm below the head of the reed should not be soaked.

3. Water thoroughly from the top the next day (return water). Later.

If you don't water for two or three days, you can spray if it's too dry. (water control, flower promotion, and bud promotion).

How to plant orchids with burst roots so that they are not easy to empty their roots.

Pour the water that is to be poured into the soil as if it were watering.

Orchids must be dried to dry the roots when repotting, so that the sunlight can kill the bacteria inside to improve the survival rate. Repotting method: pruning treatment, first cut off all the old roots and dead roots, and then sterilize; Remix the soil, select the mixed soil of sandy soil, humus soil and peaty soil as the culture soil, and disinfect it once before planting; Planting management, after planting the root system vertically into the soil, it is kept moist after watering.

Orchids must be dried to change pots, so that the root system can become softer, and the root system will not be damaged if replanted, and the ultraviolet rays of the sun can be used to kill the bacteria inside, thereby promoting the healing of wounds, otherwise it is easy to cause root infection bacteria, and the survival rate will also decrease.

1. Pruning

In the process of repotting, the orchid first cuts off all the dead roots and rotten roots on the root system, which can promote the concentration of nutrients and prevent disease breeding, and then disinfect it in carbendazim solution for a few minutes, and then place it in a ventilated and breathable environment to dry.

2. Re-allocate soil

Orchids have high requirements for soil, mainly based on well-drained and humus-rich soil, using sandy soil, humus soil, and peaty soil mixed soil as culture soil, before planting, the soil is disinfected once, and some rotten melon seed shells are placed at the bottom of the pot.

3. Planting management

Plant the root system vertically into the soil, try not to plant horizontally, pour in a fixed root water, and then put it in a semi-shaded and ventilated environment to maintain, give sufficient light treatment every day, but do not direct strong light, and need to be properly shaded in summer to facilitate the growth and development of plants.

It is not recommended. After the orchid plant is potted, the posture of the orchid plant is gradually fixed. — Potted plants.

In a clump, the old false bulb should be on one side, so that the new shoots have room for development. If there are several clusters in a pot, the old false bulbs of each bush should be relatively concentrated in the middle of the pot, so that there is enough space for new roots and shoots to develop outward.

When planting, hold the leaves with one hand and add nutrient soil with the other.

Hold the base of the orchid plant slightly upwards to stretch the root system and shake the orchid pot at the same time. Let's culture the soil.

deep into the rhizosphere; Continue to add soil and shake the pot to adjust the position and height of the plant. Press along the edge of the pot with your hands, but do not hurt the roots too much, continue to add soil and squeeze until the soil on the surface of the pot is 2-3 cm higher than the mouth of the pot, slightly steamed bread shaped. The culture soil should cover the roots of the whole turand and cover it to the base of the pseudobulb, and the depth of the filling soil is traditionally believed

Chunlan should be shallow, Whelan.

It should be deep, but generally not buried in the leaf base on the pseudobulb. When the newly-haired orchid grows in the mountains, it leaves a clear mark on the soil surface, which can be used as a standard. The size of the pot should also be commensurate with the size and number of plants, neither large pots and small plants, nor small pots and large plants.

Generally, the number of plants is expected to be full in 2-3 years. The size of the plant is commensurate with the height of the pot. It is not only conducive to growth, but also meets the requirements of ornamentation.

After planting, you can spread a layer of small stones or moss on the surface of the potting soil, preferably high-quality moss under the forest, which is not only beautiful, but also can regulate the water, and can also protect the leaf surface from being polluted by muddy water, and the new shoots will not be infected with the germs in the soil and rot their hearts; In addition, it can also slow down the erosion of the potting soil by rainwater and keep the potting soil loose.

Watering. After the planting is completed, the first water must be watered, the potting soil must be soaked, the water droplets should be small, and the impulse should not be large. If it is placed in a basin of water, do not soak it for too long.

Once the potting soil is soaked, the pots are immediately removed and then placed in a shaded place for maintenance. Fertilize. You can use "Yanwo microbial agent" + "root rooting agent" in the early stage, and the effect will be better when combined with Yanwo water-soluble fertilizer.

1 The best transplanting season for removing orchids is late spring and early summer, when the temperature is best above 20, when the flowering period is just over and new roots begin to grow. Dig out the orchids from the pot first, and if the soil is tight, you can pat the bottom of the pot or use a sterilized knife to shovel around the edge of the pot, and then gently remove it. 2. Cut off the rotten roots: Dust off the old soil on the orchid roots, and use fingers or scissors to trim off the rotten roots that are dry, withered and brown or gray.

Keep the green plump good roots. Use scissors to cut the bulb with a large gap, and apply charcoal powder or sulfur powder to the cut to prevent bacterial infection. 3. Water the pot When potting, put the orchid in the middle of the new pot, hold the seedlings in one hand, fill in the nutrient soil with the other hand, and shake the pot while filling the soil to make the roots and soil dense.

When planting, the sprouts are turned outwards to facilitate growth. After transplanting, water thoroughly, then place in a slightly damp place until the new shoots germinate, and then reduce the amount of watering. Pay attention to site ventilation to reduce orchid pests and diseases.

Orchids need to be regularly replaced in the process of breeding, so usually there is no need to prune, but if there are old roots, diseased roots and rotten roots, they need to be pruned in time, as long as the healthy root system is retained.

Does it matter if you want it once? Brother Hang must not try his best, and Brother Hang will not have a survival rate compared to Chang Chang.

The roots of the orchid do not need to be exposed when it is potted, put the orchid into the pot, arrange the roots densely, add the mixed fine soil to 2 3 cm away from the pot, lift the orchid plant slightly, and the height is subject to the upper end of the false bulb and the soil surface, not too shallow or too deep.

Gently press the potting soil so that the soil is in close contact with the roots, and then use your fingers to compact along the perimeter of the pot to avoid causing cavities when watering. If the top layer is coated with a layer of moss or broken tiles, watering will not easily cause compaction and reduce water evaporation.

The first watering adopts the pot sitting method, so that the pot absorbs enough water. Finally, put the orchid in the shade for about half a month to one month. Watering should be controlled during this time and should not be too wet.

Later, it is placed in half shade and half sun, which is ventilated and can shine into the sun in the morning. The pot should be about 1 meter high and should not be placed on the platform to prevent ants and earthworms from entering through the hole at the bottom of the pot and affecting the growth of orchids.

Half or one-third of the reed head of the orchid leaf base is on the line, and the roots should not be exposed. If you want to put moss, it is recommended that you peel off fresh moss from the roots from the mountain, the carpet is generally rooted, remove a layer of coarse soil from the pot surface, replace it with a layer of fine soil, after watering the moisture, spread the moss, and then water, gently pat it with a small wooden board until mud emerges on the moss surface, and then sprinkle water every other day, and slowly the moss will live, bright green, very beautiful. If it's a commercially available dried moss, just spread it on casually.

Because Langen likes a humid environment, he is afraid of too much humidity. And the rhizome part of the orchid is the most afraid of water. Therefore, the lower part of the pseudobulb (rhizome part) is exposed to the outside of the substrate, which is easy to cultivate. But don't leave the roots exposed.

After the orchid is trimmed, it is best to disinfect it before drying it, so that the survival rate will be higher after potting. The drying time of orchids is controlled at about 12-24 hours. The details are as follows:

How long is it appropriate to dry orchids after trimming their roots.

As the orchid grows, it needs to be repotted every 1-2 years. When repotting, the orchid can be properly pruned, pruning off the old, dead and rotten roots. After the root is trimmed, there will be sap coming out of the wound, so it needs to be dried before it can be potted.

Generally speaking, it is recommended that the orchid should be dried for about 1-2 days after pruning the roots before potting, this time period can make the orchid wound converge, and the roots are not easy to fester, and the survival rate will be higher.

Can orchids be potted directly after trimming their roots?

It is not recommended to pot the orchid directly after trimming the roots, otherwise the orchid will be buried in the soil with a wound, which will be easily infected with bacteria and cause root rot, which will affect the survival rate of the orchid. The root wound of the orchid has been scabbed after drying, and planting it in the soil can reduce the bacterial infection of the orchid and improve the survival rate.

The drying time of orchids after root pruning is not fixed, and the length of time needs to be determined according to air humidity and temperature. Orchids with good roots often have two characteristics, one is that the roots are dry and slightly whitish, and the other is that the roots feel soft when touched by hand.

Mode of reproduction. 1.Branches.

It can be carried out in both spring and autumn, and is generally divided every three years. All plants with strong growth and dense false corms can be divided, and at least 5 connected false corms should be kept in each cluster after dividing. Irrigation should be reduced before dividing the plants to make the potting soil drier.

When potting after dividing, first cover the hole at the bottom of the pot with broken tiles, then lay coarse stones, accounting for 1 5-1 4 depth of the pot, then put coarse soil and a small amount of fine soil, and then plant with sandy loam soil rich in humus. The planting depth is to bury the false bulb in the soil, leave 2cm along the edge of the pot, spread the green cloud grass or fine stones, and finally water thoroughly, put it in the shade for 10-15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

2.Sow. Orchids are commonly propagated by dividing, sowing and tissue culture. Orchid seeds are very fine, there is only one incomplete embryo in the seed, the germination ability is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing methods, so it is necessary to use orchid fungi or artificial medium to supply nutrients in order to germinate.

It is best to choose the fruit that has not yet cracked for sowing, after the surface is sterilized with 75% alcohol, take out the seeds, soak them in 10% sodium hypochlorite for 5-10 minutes, take them out and rinse them with sterile water 3 times to sow them in the culture flask containing the medium, and then put them in the dark culture room, keep the temperature at about 25, and then move them to the light after germination to form the original corm. From sowing to transplanting, it takes six months to a year. Tissue culture has been successful, and this method can be used to propagate where possible.

1. Orchids should be dried for 1-2 days after pruning. After trimming the roots, the juice will flow out of the wound, and the wound will scar after drying, and the roots should not fester, and it is easier to survive. When pruning the root system, you should keep as much as possible, only cut off the part, and disinfect it after pruning before drying.

2. Orchids generally need to be treated after pruning, farmers close their hands and use the simplest drying method, and they can be dried in the sun in early spring (orchid seedlings are covered with newspapers), and the wound can be dried in about half a day. In the later spring, it is dried in a cool place with light leakage, and normal orchid seedlings can be treated in this way. Some orchid seedlings may have signs of germs, so they should apply fungicidal powder to the wound, and of course do not build a sedan car to rent a potion.

Orchids must be dried for root repot.

When the orchid is repotted, proper drying of the roots can make the root system softer, and the root system will not be damaged during the operation, and the drying process can also use sunlight to kill some germs, which can promote wound healing, so that filial piety can promote the potting as soon as possible. If the roots are not dried and planted directly in the soil, the wound is easily infected with bacteria, which will reduce the survival rate.

When changing pots and transplanting orchids, you need to choose a flower pot with a suitable size and loose texture, and there should be enough holes in the side wall of the pot to facilitate the air permeability and drainage of the potting soil, and the pot should not be too deep, otherwise it is easy to accumulate water.

When transplanting orchids, it is not advisable to use ordinary soil, it is best to use loose nutrient soil of the sedan mold, which can be mixed together with coconut shell blocks, moss, perlite, and cedar bark to make a nutrient-rich and breathable soil.

Cultivation conditions of orchids

1. Soil conditions.

Orchids are suitable for growing in loose, breathable and fertile soil, when cultivating orchids, it is necessary to use humus, sandy soil and garden soil to mix into a cultivation medium, and to mix potassium permanganate solution into the soil to disinfect and sterilize, which is conducive to the healthy growth of orchids.

2. Lighting conditions.

Orchids are not tolerant to strong direct light, when cultivating orchids, it is necessary to place the plants in a ventilated semi-shaded environment in spring, summer and autumn to avoid being burned by the sun and promote the vigorous growth of orchids, and in winter the orchids can be placed in a sunny place to promote their photosynthesis.

3. Watering method.

Orchids like water, but do not tolerate waterlogging, when breeding orchids, you need to water once a week, you can use non-polluting mineral water, or dry the tap water for 1-2 days before use, and when watering orchids, you need to let the water flow down the edge of the pot to avoid rotten roots.
