Why are the orchid plants that come down the mountain very tall, and after 1 or 2 years of planting

That's because the plant is not suitable for keeping at home, because the temperature in the home is not the same as in the mountains.

Downhill orchid: Dressed up or refers to a wild orchid.

Downhill dwarf species: refers to its dwarf species in the wild state, the dwarf species is a variation of normal orchids, and it is less common to be a dwarf species in the wild state, and it has a certain potential to be explored through artificial cultivation. Dwarf species are different from dwarf grass, and human dwarfs are rotten or the same, must be genetic mutation hall history of different dwarf has certain characteristics to be considered dwarf, the first characteristic is the spiral root, the second characteristic is the skin, and the third characteristic is the fish scale armor.

So downhill dwarf orchids are wild orchids that are normally variant.

This is caused by improper maintenance, if you do not fertilize for a long time, insufficient nutrients will cause the orchid to grow smaller and shorter, in addition, poor roots or soil will also affect the growth of orchids to a certain extent.

If the root system of an orchid is compared to the human body, it is equivalent to the stomach and intestines. The function of the root system is to absorb nutrients, the nutrients in the soil are like the nutrients in the grain, through the digestion of the stomach and intestines can become beneficial nutrients to the human body, if the root system of the orchid is not good, it can not timely convert the nutrients needed by the orchid into the energy required by the plant, resulting in adverse effects such as stiff seedlings.

The right way to maintain it: rough acceptance.

1. Replace the planting material.

It is necessary to use a planting material with good air permeability, it is difficult to raise orchids with hardened and breath-holding planting material, it is recommended to combine humus + rotten pine bark, and you can also add some gravel particles under moss.

2. Illumination. Giving orchids more light can promote the photosynthesis of their leaves, and the more fully photosynthesized, the more robust the plant.

3. Increase the application of phosphorus and potassium fertilizer and Yanwo root rooting agent to help orchids strengthen their roots and improve plant growth.

Lan You asked: Why is Chunlan getting shorter and shorter?

Before this question, we must first know why the leaves of orchids change with the change of environment? The role of orchids is to photosynthesize by breathing carbon dioxide in the air. Of course, at night it will also be mischievous, inhaling oxygen and exhaling carbon dioxide.

There is also a kind of spring orchid whose leaves become shorter but sickly, such as the orchid leaf angle is normal, and there is another orchid, after two years of raising, the angle will become smaller and smaller, which is a typical phosphorus deficiency symptom.

Phosphorus-deficient orchid plants will become shorter and shorter, and novice orchids often misunderstand that it is dwarfing in a normal state, which is actually a symptom of stunted plant development. Phosphorus deficiency is easy to identify, the angle of the leaves becomes smaller, and the leaves have faint red spots or red spots. At this time, it is necessary to supplement phosphate fertilizer, which can be used to water the roots with superphosphate leaching solution, and Xiangzena can also be sprayed with potassium dihydrogen phosphate on the foliar surface.

Dwarf orchids do not grow taller again because the shape has stabilized and the branches that come out of the plant do not grow taller again.

A flower stem of spring orchid often blooms one, occasionally opens two, most of the flower stems are not high, hidden below the leaf surface, there are not many large shelves more than the leaf surface, and management, environment and varieties are related, the height of the flower stem is generally about 10cm, the length can reach more than 20 cm, the opening is too short, it is not beautiful to stick to the planting material or the pot surface, and it does not reflect the spirit of the orchid.

The height after dwarfing is more appropriate, and the orange manuscript will not look too thin, mainly depending on personal preference.

Orchid planting attention:

Phosphate fertilizer can help the growth of roots and flower buds, so we use pine bark, humus soil to raise orchids is very good, we can also apply some phosphorus and potassium fertilizer appropriately, it is not recommended to consume too much nitrogen fertilizer, too much nitrogen fertilizer will seriously affect the flowering of Danwu withering, help the leaves grow wildly.

In addition, we need to bask in more sunlight, as long as the temperature is not higher than 30 degrees Celsius, we can bask in more sun, only the mold hole has enough light, we can better photosynthesize, synthesize more nutrients. To maintain orchids, generally raise leaves on cloudy days and flower buds in the sun.

After more than 20 days of planting, the leaves of the orchid spread out, which was caused by improper cultivation and management measures.

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

Light is an important factor in the formation of flower buds.

Although orchids love coolness, they rarely bloom if they are kept in a hidden place all year round. Orchid artists have long discovered that the leaves of the Yin Orchid of the Mountain are long and the flowers are sparse, and the Yang Orchid of the Mountain is short and has many flowers. Therefore, when cultivating orchids, we must pay attention to the problem of light.

In spring and summer, orchids are best shaded by reed curtains or placed in windows with ventilation facing east and south. The orchid under the curtain should be repotted once every half month, so that the orchid receives light on all sides, which is conducive to the balanced growth of the plant.

When autumn is cool, the potted orchid should be removed from the shade and let it bask in the sun for half a day in the morning, but be careful not to dry out in autumn. In cold weather, it is placed indoors under the south window for wintering, but it does not have to be too warm, and it is best to cover it with a plastic film cover to maintain the proper humidity of the leaves. As for the prevention and control of pests and diseases, such as brown rust and white silk disease, use stone sulfur mixture**.

If there is an ant nest, you can soak the pot in water to drive it away. In addition, the use of fertile leaf water-soluble fertilizer can improve the resistance of orchids to diseases and pests.

Practice has proved that orchids are eight points dry, two points wet is the best, and the flowering period and the leaf bud stage should be watered less. During the rainy season, you should move back indoors or build a shelter to protect yourself from the rain. In summer, it should be watered early in the morning or evening, not too much, and the amount of watering in autumn can be increased as appropriate.

During the dry season, spray every evening. When spraying, it should be sprayed upward, so that the fog point is fine and even, so that the leaf surface is moist, the ground is moist, and the air humidity is increased. Sometimes it is best to spray several times a day, and watering should be watered from the edge of the pot, not poured on the head, not at noon.

Although watering in winter can be greatly reduced, but not without watering, pay attention not to let the potting soil dry out, winter is not early spring and watering causes the leaf sheath to be wet, to be moved indoors after drying, so as not to rot. In short, dry is watered, wet is stopped, appropriate dry for the principle.

It is better to use rainwater and spring water, and all kinds of water should be taken and stored in the tank first, so that the pollutants in the water can be precipitated, the water temperature is normal, and the chlorine in the tap water is exhausted, and then poured.
