How to raise the orchid, how to raise the orchid

Hello, when I used to work in the wholesale flower market, I saw a lot of: three plants in one pot (d=25cm). If you have four strains and compare them, let's do it! Yes, yes.

How to raise a large orchid.

Characteristics of Cymbidium grandiflora: The root system is developed, and it is easy to grow poorly due to poor ventilation and drainage.

Maintenance: Use pots: porcelain pots are used as set pots, not directly planted in porcelain pots.

That is to say, what basin to use when you buy it back is directly put into a large porcelain basin, which is generally a large pot of three small pots. The gaps are filled with small stones, and if the small stones are not beautiful, green water plants are spread on them. It is also possible to use peat:

It retains water and fertilizer but is expensive.

Fertilizer: Because of its large plant size and large appetite, it is especially necessary for sufficient fertilizer during the pregnancy bud period (multi-phosphorus fertilizer). During the vegetative growth period, compound fertilizer based on nitrogen fertilizer is applied, and a little potassium dihydrogen phosphate can be added to urea.

If the fertility is insufficient, you can also spray 2%o potassium dihydrogen phosphate on the foliar surface, about once every 5 days. Pay attention to the foliage, light green is better, dark green is to control fertilization (less nitrogen fertilizer at this time).

Light: Maintain light time, which is especially important for scented large-flowered orchids.

Lack of fertility and light is an important reason why the large-flowered orchid cannot bloom year after year, and the large flowering is also one of the reasons.

You can also go to a hundred basic maintenance knowledge is there. The entry is: Cymbidium grandiflora.

It is best to use bark or shavings, thick saws, orchid soil can also be raised but not very good.

1. Soil: Soil with good air permeability and loose and fertile soil should be used for breeding, and it can be prepared with humus and garden soil mixed with an appropriate amount of sand. In addition, it is also necessary to pay attention to disinfection before entering the soil, and high-temperature disinfection is enough to prevent insect eggs inside.

2. Watering: It likes a moist environment, and the water storage capacity of the rhizome is very strong, so it can be replenished more water at ordinary times, especially in summer, in addition to water irrigation, it is necessary to sprinkle more water around the plant to cool down. The approximate frequency is twice a day in the summer and once every three or four days in other seasons.

3. Temperature: It is the most suitable temperature between 10 degrees and 25 degrees Celsius. It is not resistant to high temperatures, and it is necessary to pay attention to cooling down when it exceeds 35 degrees in summer. In winter, it is best to maintain it above 10 degrees Celsius to avoid frostbite.

4. Light: It likes the irradiation of scattered light, can not tolerate strong light, and should pay attention to shade in summer. In winter, the light is weak, so full sunlight can be given.

If the ventilation is not good during the maintenance period, the environment is unsuitable and easy to cause pests and diseases, such as fungal anthracnose, bacterial diseases and some pests and diseases. Once the diseased leaves can be clearly seen, the state of the plant will also be affected, and the drug should be sprayed as soon as possible to prevent the situation from worsening and hindering growth.

1. Flower pot selection: If you want to breed large-flowered orchids, you need to choose pots with good air permeability to breed, because large-flowered orchids cannot accumulate water, and once the water accumulates, it will lead to rotten roots.

2. Soil requirements: Cymbidium grandiflora has certain requirements for soil, must be loose, we generally have better choose self-made, use humus soil, garden soil, sandy soil, according to the ratio of 2:2:4 for mixed use.

3. Sunlight demand: The demand for sunlight is relatively limited, we generally only need to give it the morning sunlight, and at other times, we can put it in the astigmatism to breed.

4. Reasonable watering: the demand for water is limited, we must not water more, choose to water every 2 days in spring and autumn, several times a day in summer, and water once in about half a month in winter.

5. Reasonable fertilization: the demand for water is limited, we must not water more, choose to water every 2 days in spring and autumn, several times a day in summer, and water once in about half a month in winter.

6. Pruning branches and leaves: In the process of growth, there will be some wilted branches and leaves, we need to prune them off in time, generally if we are afraid of growing too tall, we also need to carry out topping treatment.

Breeding large-flowered orchid to ensure that the soil is suitable, and every 1 2 years need to replace the soil, do a good job of temperature control measures in summer and winter, no more than 35 in summer, not less than 10 in winter. Ensure that the light is suitable, at least 60% shade in summer, and at the same time master the correct watering and fertilization methods to ensure the growth of plants.

To raise the large-flowered orchid well, it is necessary to ensure that the soil is more suitable, and that the soil is loose and fertile, has good drainage and abundant nutrients. Peat, river sand, and pastoral soil can be mixed and prepared, and a small amount of organic fertilizer needs to be added to ensure that the soil nutrients are abundant.

Breeding large-flowered orchid potted plants require 1 2 years to replace the soil, timely soil change can provide a better growth environment for the plant, in the soil change needs to prune the roots of the plant, to ensure the growth of the plant.

Orchid grandiflora likes a warm environment, and its most suitable temperature for growth is about 20, and the temperature control measures for breeding Macroflora orchid should be done in summer and winter. In summer, put it in a cool and ventilated environment, control the temperature not to exceed 35, and in winter, move it indoors to keep warm, and control the temperature not less than 10.

Large-flowered orchid likes a semi-shady environment, and the cultivation of large-flowered orchid must control the light, and it will be placed in a bright place in spring and autumn; In summer, the sun is too strong, and at least 60% of the shade is provided during this time; In winter, it is more conducive to the overwintering of the plant by placing it in a sunny place.

Reasonable watering and fertilization are the key to the growth of Cymbidium grandiflora, and watering should master the principle of seeing dry and wet, and keep the soil moist but not waterlogged. Fertilization should grasp the principle of thin fertilizer and more application, choose thin liquid fertilizer to be applied appropriately, and avoid excessive and concentrated fertilizer.

The cultivation method of the orchid is as follows:

1. Soil

Dahui orchid is a fleshy root, its root system contains a lot of water, and the penetration is poor, suitable for growing in well-drained soil, when cultivating Dahui orchid, you can use aquatic plants, coconut peat soil, wood chips and ceramsite mixed soil to make the soil, and to change the potting soil every 1 to 2 years.

2. Temperature

Dahui orchid likes warm winter and cool summer climate, the growth temperature is 10 to 25 degrees, and the night temperature is about 10 degrees, especially during the flowering period to maintain the temperature above 5 degrees, and below 15 degrees can extend the flowering period for more than 3 months.

3. Illumination

Try to put it in a bright position of scattered light, in summer when the light is strong, you need to shade it, in the autumn in order to make the plant better form flower buds and healthy winter, you can let it be exposed to more sunlight, and in winter you need to put it in a greenhouse with strong sunshine and high temperature.

4. Watering

Water according to the dryness and wetness of the soil, and keep the soil slightly moist. Increase watering in the hot summer climate, and reduce the frequency of watering in the cold winter, and try to keep the temperature of the water in line with the room temperature to avoid frostbite to plant roots.

5. Fertilization

Generally, in the peak growing season, fertilizer should be applied once every ten days, and the fertilizer is better with thin organic fertilizer. In the spring and summer growing season, it is advisable to apply a more balanced compound fertilizer of phosphorus and potassium, and more phosphorus and potassium fertilizer should be applied in autumn, and potassium dihydrogen phosphate can also be sprayed directly on the foliar surface to promote flower bud differentiation and facilitate flowering.
