Why do Hanlan raise fewer people, and what are the tips for maintenance?

The planting management of Hanlan is very different from other varieties, and it is easier to master and maintain it.

There are few people raised by Hanlan because Hanlan is more difficult to raise and it is not easy to survive.

Hanlan is difficult to raise, and purebred Hanlan is even more difficult to raise, especially for novices. As a major strain and rising star of Chinese orchids, Han Orchid has attracted people's attention with its majestic leaves, tall flower arrows, elegant flowers and charming fragrance, and the number of cultivation enthusiasts is increasing.

Orchid (is a native plant of the genus Orchidaceae, the pseudobulb is narrowly ovate-shaped, and is encapsulated in the leaf base. Leaves band-shaped, thinly leathery, dark green, often with fine teeth on the anterior margins. The flowers are often pale yellow-green with pale yellow lip petals, but also have other colors and often have a strong aroma.

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 the pot is put on after dividing, the broken tiles are first covered on the hole at the bottom of the pot.

When maintaining the orchid, the temperature of the growing environment should be controlled between 18 and 28 degrees, so as to provide the plant with no less than six hours of scattered light every day, and when the soil is dry, it is necessary to immediately replenish water for the orchid to prevent the leaves from drying out.

1. Temperature

When the temperature of the plant growth environment is lower than 10 degrees or higher than 30 degrees, the leaves will gradually wither and die, so the maintenance of the cold orchid should be kept between 18 and 28 degrees in summer and winter.

2. Illumination

The reason for the lack of people is that the plant is suitable for growing under scattered light, if it is placed in strong light or shading, the leaves will wilt, so the maintenance of the cold orchid should be placed on the balcony of the rising sun, when the summer light is strong, you need to shade the plant in time.

3. Moisture

Hanlan raises few people is the reason for the high humidity requirements of the plant, Hanlan likes to grow in a humid environment, in the process of maintenance, in the summer and autumn to be trapped and cracked, water the plant every one to two days, to ensure that the humidity in the soil is not less than 70%, and at the same time spray the source of water mist twice a day around the Hanlan to improve the humidity in the air.

Shade-loving and strengthening shade Shade is the most advanced premise for raising a good cold orchid, and it is also an important condition to ensure that its leaves are shiny and green, and there are fewer diseases. Most of the wild orchids grow in dense broad-leaved forests, under mixed forests, with high shade.

The domesticated orchid should strive to imitate its original ecological environment, and the shading degree should be doubled, especially in the high temperature season when the light is strong, and the shading degree must be more than 80%. If you raise orchids on the south balcony with good lighting, the orchid pot should be placed in a place where there is little sunlight, and it is best to place the orchid on the lower layer of the railing, so that other plants can block the light on it, which will have a very good effect.

It is advisable to grow in humidity and increase humidity The place where the wild orchid grows is perennially filled with fog, and the humidity is particularly high, so it is difficult to find its traces in a slightly dry place facing the sun. Therefore, it is important to maintain the humidity of the environment when raising a domestic orchid. Many orchid friends will mix Hanlan with Chunlan and Huilan, but in fact, the humidity suitable for Chunlan and Huilan is not enough for Hanlan.

The humidity in Hanlan's room is about 10% higher than that of the substitute, and it can reach 40%-70% during the day, and the relative humidity is not less than 80% at night. Take care to maintain ventilation.

Treat it differently and fertilize it scientifically because of his different varieties, and the false bulbs are large and small. The small pseudobulb of the cold orchid has limited nutrients to store, and it is easy to bloom and has large flowers, resulting in more nutrient consumption, so fertilization must be important.

Diligent division to improve germination rate Its reproduction rate is low, and the slow increase of seedlings is one of the difficulties in the cultivation of Hanlan, and there is often a saying of "nine deaths and one life". It is not easy to increase the seedlings in the cold seedlings of the mountain, the new seedlings have not yet grown, and the old seedlings have fallen. Due to the fact that the cold orchid is more frequent and has a longer flowering period, the nutrient consumption is too large, and the old seedlings are unable to germinate more when maintaining their own nutrients, which causes difficulties in increasing seedlings.

In fact, the Hanlan plant is robust, the root system is developed, and the new seedlings that have become seedlings can be propagated by single seedlings, and even the leafless old man can be cut and planted. Seedlings usually begin to be divided in August, which is conducive to inhibiting the formation of germination, reducing nutrient consumption and improving their ability to survive independently.

Mixed planting material to promote growth After the comparison of multiple planting material formulas, it was found that it is best to use mixed planting material for cultivating Hanlan, and no matter what kind of granular planting material is used, it should be mixed with some mountain mud or humus, so that Hanlan grows best.

1. What to do with Hanlan just bought it.

The newly bought Hanlan can be spread out to dry first, check whether the roots are rotten, and if there is, you need to cut it off with scissors. After that, the roots of the plant are soaked in a 5% potassium permenthoate solution for half an hour to sterilize the roots of the plant. After soaking, put it in a ventilated place to dry, and finally choose a suitable potting soil for potting.

Second, the specific breeding method.

1.Soil: You can choose a more fertile soil for cultivating Hanlan.

When planting, you can choose a tall pot, in the position of one-third of the basin, use coarse-grained bricks and styrofoam blocks to cushion the bottom, mix ears with red loam brick grains and sand in the middle to one-third of the pot, and mix a small amount of humus with sand grains the size of rice grains in the upper part.

2.Watering: It likes moisture and avoids dryness.

It is not suitable to water too much when you first buy it, you can water it every 3-5 days, and spray water on the foliar surface once a day to ensure the moisture of the soil. It should be noted that each watering must be done thoroughly, but not allow the potting soil to accumulate water, otherwise the roots of the plant are very likely to rot.

In summer, when the temperature exceeds 35, it will not grow well, so it needs to be shaded and cooled. Under normal circumstances, its optimal growth temperature is 15 -30, and when the temperature is lower than 5 in winter, it will affect its growth ability, and it will be dormant at this time, so certain heat preservation measures should be taken in winter so that it can survive the winter safely.

4.Light: It likes shade and avoids direct sunlight, and too strong light can easily lead to sunburn and sunburn.

When you first buy it, you can put it in a semi-shady environment to maintain it, and give it diffused light appropriately. However, it should not be overly shaded or kept indoors for a long time, which can easily cause poor growth and difficult flowering. Under normal circumstances, under the condition of ensuring that the leaves of the plant are not burned, you can see more sunlight appropriately.

5.Fertilization: It does not require a lot of fertilizer, and during the slow potting period, it is not necessary to apply fertilizer at all.

Under normal circumstances, fertilizer can be applied 2-3 times a month, with potassium dihydrogen phosphate, orchid king, etc. alternately used Qi Hui as foliar fertilization. During the growth period of new shoots, some urea can be added appropriately, and high potassium fertilizer can be sprayed two to three times during the maturity period of new seedlings. We can increase the application of thin organic fertilizer once a month from April to June and September to October, and avoid applying thick fertilizer to avoid fertilizer damage.
