Are orchids aerial rooted? What are the roots of the orchid like?

To raise an orchid, you must first raise a good root, and if the root is good, the orchid will survive, emerge and bloom. The roots of orchids are fleshy roots, aerial roots.

This is all well known to Lan friends. How can I raise Langen? What exactly is the cause of empty roots in orchids?

There is a saying that the empty roots of orchids are caused by the fact that the roots are not in close contact with the planting material, and the roots of the orchids cannot absorb water. At a cursory glance, it feels a little reasonable, and the novice Lan You will basically believe it. Is this really the case? In fact, this statement is very wrong.

The so-called aerial root, it has a condition to contact with air, and if the root is in close contact with the planting material, it loses the space to breathe fresh air. This is also the reason why the farmer has always said that the orchid planting material should be breathable. Only when the planting material is breathable enough can Langen be exposed to more air and grow healthily.

I have grown orchids with pure pine bark, and although it is not fertile, the orchid roots grow very well in pure pine bark. As we all know about pine bark, there are many gaps between the bark, and it is impossible for the root to be in close contact with the planting material, on the contrary, there are many orchid roots that are suspended in the gap without planting material.

And some Lan friends listened to the previous statement, Langen must be in close contact with the planting material, so that the phenomenon of empty roots will not occur. So they refine the planting material again and again, and compact it again and again when potting. In fact, this is contrary to the principle of orchid growth.

The empty roots of orchids are actually that when the potting soil is too dry, the roots of orchids cannot absorb enough water, but the growth of orchids cannot be short of water. Then, the orchid plant can only absorb water from the fleshy roots. At this time, if the hydration does not keep up, the root will always be ** water, and this dehydration is not visible from the leaves, because the leaves have not lost water.

Therefore, orchid growers often feel that it is not yet time to water, and the dragging is drier and drier until the water of the orchid root is sucked dry, which causes the empty roots of the orchid.

In our cognition, planting green plants and flowers are planted in the soil, but orchids as green plants, it has some differences from ordinary green plants and flowers, it is difficult to plant well with soil, it needs professional planting materials, to use pine bark, chestnut bark planting materials, so that it can moisturize.

Orchids are aerial roots, and the roots need air to grow, and in such an airtight environment, orchid roots are equivalent to being unable to breathe, and the formation of rotten roots is inevitable.

The internal structure of the root is a typical monocot type. Its cortical cells are more developed, and there are symbiotic fungi called rhizomes. What grows in the ground is called ground rooting, and what grows in the air is called aerial rooting.

The outermost layer is the root cover, which originates from the epidermal tissue. The cells of the root tissue are elongated and cylindrical, polygonal, arranged radially from the center outward. When the root cover cells mature, the protoplasm disintegrates, and the cells develop thickened streaks.

The function of root tissues is to protect the cortex, absorb water, and reduce and protect the loss of water from the interior of the cortex.

The middle layer of Langen is cortical tissue, and the cells are relatively developed, with about 20 layers of polygonal cells, and the thickness is about 3 times that of the root cover tissue, accounting for most of the roots. The outermost layer of root cover tissue is the outer cortex, which is composed of a single layer of cells, radially arranged, neat, and larger than the average root cover cell.

The inner layer of Langen is the central column, and the outermost layer of the central column is connected to the cortex is the endothelial layer, and the Kjeldahl zone on the endothelial cells is well developed. Tightly attached to the endothelial layer is a vascular sheath. Both the endothelial layer and the vascular sheath have two different types of cells.

in the periphery of the phloem are thick-walled cells; In the periphery of the xylem, they are parenchyma cells.

Orchids like shade and are afraid of direct sunlight; Prefer moisture, avoid dryness; It likes to be fertile and rich in a lot of humus; A well-ventilated environment.

1. Observe the root system. It is required that the root system is intact, with no blackheads or fewer blackheads, the root length is moderate, and it is relatively stretched, and if it is tightly squeezed together, it may affect the growth space of new shoots. Depending on the specific season and temperature, you can see if there is a crystal head.

2. Observe the leaf feet. During the germination season, the legs of the leaves turn yellow gradually, so that they retain their normal shape after drying. Some unhealthy grasses have a short period of brown leaf feet that cling to the new leaves.

3. Observe the sprouts. If the position of the new sprout is too high, the new grass will generally be weaker than the mother grass, if it is a submarine bud, the new seedling will be stronger than the mother grass, but then the grass will be sent later, because the position is too low, there is a risk, it is best that the position of the new sprout is slightly lower than the mother grass, so that the development space is relatively large, and the future is also easy to divide the seedlings. According to my breeding experience in the past two years, from the bottom of the pot to two-thirds of the orchid pot, the use of medium particles to plant orchids, the above use of small particles to plant orchids, autumn and the spring of the second year appropriate watering, can better avoid the sea buds.

4. Observe the incision. Dealing with the incision is the key step to prevent germs from entering the orchid and the occurrence of grass inversion, when introducing seeds, we should try to choose the grass with a small incision, and the small incision also indicates that the orchid has matured and the growth cycle is complete.

1. Water absorption: It can absorb water in the soil and promote the vigorous growth of branches and leaves. 2. Absorption of nutrients:

Nutrients such as nitrogen, phosphorus, potassium, and organic matter in the soil can be utilized. 3. Maintenance method: During the peak growth period, apply the well-rotted thin cake fertilizer water every half month.

4. Pest control: When orchids are diseased, spray pesticides in time for control.

1. Absorb water

The roots of the orchid can absorb the water in the soil, transport water for the growth of branches and leaves, promote the vigorous growth of branches and leaves, and provide good basic conditions for the growth and development of plants, so the more orchid roots grow, the more lush the branches and leaves of the orchid will be.

2. Absorption of nutrients:

Orchid roots grow thick and strong, and the erect root system is cylindrical, which can absorb nutrients such as nitrogen, phosphorus, potassium, organic matter in the soil, and transport them to the plant, so as to promote the germination and growth of orchids, and also help orchid branches and leaves to grow luxuriantly and flowering brightly.

3. Maintenance method

In the process of maintaining orchids, water every two to three days in spring and autumn, and water once a day in high temperature in summer.

4. Pest control

Orchid peanuts have been attacked by pests and diseases for a long time, so in the maintenance process, it is necessary to spray fungicidal drugs in time to avoid damage to the roots or leaves of the plant and consume unnecessary nutrients.

Healthy cultivation methods for orchid roots: soil should be well arranged, humidity should be sufficient, watering, fertilization, and pest control should be controlled.

1. The soil should be well configured.

The root system of orchids is a relatively thick radish root. This root system likes moisture, but is particularly afraid of stagnant water, so the arrangement mechanism for orchids should be a combination of coarse and fine materials. It is best to use large particles to cushion the bottom, and the configuration of the mechanism should be appropriate, which can be composed of humus, pine needle soil and granular soil, bark or organic fertilizer.

2. The humidity should be sufficient.

The orchid likes an environment with high air humidity, and the original environment of its grandson is next to a mountain stream where the air humidity is greater than that of his brother Kaisen. When maintaining orchids, do not put them in too dry places, you can often spray and moisturize orchids, enhance ventilation, and get close to its original ecological environment to raise them well.

3. Watering. To raise orchids well, it takes three years to water, and watering orchids is a university question, so that the potting soil is moist but not wet. When watering, do not pour it on the heart of the orchid, and do not water it on the buds of the orchid.

Usually wait for the planting material to dry before watering, so that the potting soil can alternate between dry and wet. Let the root system get a good breath, so that the roots can be nourished well.

4. Fertilization. When fertilizing orchids, try to avoid using chemical fertilizers. Organic fertilizers, such as fermented dried sheep manure, can be used to prevent soil compaction and acidification caused by long-term use of chemical fertilizers, which can affect root growth.

Regular use of organic fertilizer can improve the vitality of the soil, make the root system healthy, and enhance the resistance.

5. Prevention and control of pests and diseases.

Generally speaking, the diseases that harm orchid roots mainly include root rot, white silk disease and so on. The insect pests that harm the roots of orchids mainly include earthworms, snails, root nematodes, etc., the main control of root diseases and insect pests is more difficult, it is particularly large for orchid plants, and the orchid seedlings and planting materials should be strictly sterilized and insecticidal before planting orchid seedlings.

1.It is advisable to use loose, breathable, and slightly acidic granular plant materials with good drainage performance to cultivate orchids, so that orchids can grow roots faster. Common orchid plants include pine chestnut king, stone plant, snake wood, bark, leaves, ceramsite, bricks, tiles, coconut shells, peanut shells, weathered stones, humus soil, etc.

In addition, it can also be properly loosened to increase the voids of the soil, which is conducive to the growth of orchid roots. In general, once the circumference is loosened, the soil can be used. 2.

Light ensures that the orchid receives a reasonable amount of sunlight. Orchids are best basked in the sun in the morning. Because the morning sun is not so strong, it will be of great help to the growth of orchids.

The light should be controlled for about two hours, which can help the orchid quickly take root. 3.Water and fertilizer management should be reasonable.

Water once a day in the morning to keep the soil moist. When watering, try not to water the leaves, only around the roots. Reasonable control of watering amount and frequency of watering will make the plant grow more quickly and sprout.

Fertilization should be thin and diligent, and the fertilizer concentration must not be too high. You can choose a special fertilizer for orchids and apply it once a week to let the orchids take root quickly. 4.

Temperatures that are too high or too low can affect the normal growth of orchids. Try to control the temperature at about 25 degrees, which is conducive to the rooting of orchids. 5.

Rooting powder can be applied to the orchid with proper rooting powder to help the orchid take root quickly. After loosening the soil, sprinkle infiltration and slow rooting powder, so that the orchid can take root quickly.
