What if the fragrant snow orchid does not blossom, adjust the temperature and increase the light / mosaic disease spray

Xiangxue orchid, a kind of highly effective flower, not only blooms beautifully, but also can be used medicinally to cure diseases, so it is especially lovable. However, although the efficacy of Xiangxuelan is strong, the flower friends who raise it are basically to see its beautiful flowers. But in the breeding process, many flower friends of fragrant snow orchid do not blossom, this is why? Today, the editor will answer your doubts.

First, fragrant snow orchid does not blossom, look for the cause

The beauty of fragrant snow orchid should be impressed by those who have seen it. It has beautiful flowers, rich colors and excellent appreciation. But if the fragrant snow orchid does not blossom, the flower friends must be in a hurry! In order to solve everyone's problems, the editor inquired everywhere and finally summed up five reasons why Champagne did not bloom: lack of flowering time, lack of light, temperature discomfort, too few nutrients and diseases and insect pests.

2. The solution to the reason why Xiangxue orchid does not blossom

1. It is not time for flowering.

If Xiangxue does not blossom, we should first consider its planting time, because for Xiangxue orchid, it does not blossom in the first year of planting, but takes three to four years.

Solution: if the flowering time is not up, it is very simple, this is a normal phenomenon, we just need to continue to follow the cultivation method of fragrant snow orchid, and so on, it will blossom naturally after 3-4 years of planting.

2. Lack of light

We all know that light is necessary for vanilla to blossom. So if Xiangxue orchid doesn't blossom for a long time, we can observe its growth state and see if it lacks light.

Solution: if it is the lack of light that causes Champagne not to blossom, then we should move it to a place with plenty of light and let it bathe in the warm sun. Of course, the light can not be too strong, otherwise the flowers do not bloom, there will be symptoms of yellowing leaves of sweet cherry.

3. Lack of nutrients

Plants need to consume a lot of nutrients to bloom. So Xiangxue orchid does not blossom, we should see if the plant is in short supply of nutrients.

Solution: if it is caused by a lack of nutrients, we can give it some fertilizer, such as some potassium dihydrogen phosphate and other nutrients, can help sweet cherry blossom.

4. Temperature discomfort

With the growth habits of Xiangxue orchid, we know that it likes warmth, and when it blossoms, the temperature should be controlled at 15-25 ℃. If the temperature is not right, Champagne will not blossom.

Solution: if it is the temperature, it is very simple, just adjust the temperature, set the temperature to 15-25 ℃, keep it for a period of time, and the fragrant cherry will blossom.

5. Mosaic disease

In addition to the above, the reason why Xiangxue orchid does not blossom may also be that it suffers from mosaic disease. It is mentioned in the pest control of Xiangxue orchid, but when it suffers from mosaic disease, the plant will become short, the seed ball will degenerate, and the result will not blossom.

Solution: once a diseased plant is found, it should be removed in time so as not to attract insects to absorb juice and spread by friction. In addition, 40% omethoate 1500 times or 2.5% cypermethrin 3000 times were sprayed on the foliar surface.

Generally speaking, fragrant snow orchid is not difficult to raise, but no matter how easy to raise plants, it is also necessary to "raise", so in order for fragrant snow orchid to blossom, we must take good care of it. Of course, there is no blooming fragrant snow orchid situation, we do not need to be in such a hurry, according to the above method for the solution. Finally, may everyone's fragrant snow orchid blossom beautifully.

The Culture methods and matters needing attention of Xiangxue Orchid

Xiangxue orchid is a very beautiful flower plant, its color is as white as snow, the flower fragrance is as faint as orchid, deeply loved by people. Today, I will tell you the breeding methods and points for attention of Xiangxue orchid, as well as the flower language of Xiangxue orchid.

Culture methods of Xiangxue orchid:

1. Soil: Xiangxuelan likes sandy loam with rich organic matter, strong water retention and good drainage, pH6~7.2.

2. Watering: the soil must be kept moist before budding. After budding, the amount of water should be reduced step by step, and the soil surface should be kept dry as far as possible, so as to reduce the air humidity and prevent diseases.

3. Lighting: although Xiangxuelan likes light, it should also avoid strong light. When the light is too strong and the temperature is high, a shading net with a light transmittance of 70% can be used to shade.

4. Temperature: temperature management is very important for the production of cut flowers of vanilla, and the cold tolerance is poor. The suitable temperature for growth is 15: 20 ℃, and the lowest temperature for overwintering is 3: 5 ℃.

5. Fertilization: the organic fertilizer and compound fertilizer applied before planting can basically meet the growth needs, but if the plant growth is weak, ammonium nitrate, urea and potassium sulfate should be applied again at 2-4 leaves. 0.2% potassium dihydrogen phosphate is used as foliar fertilizer during the first flowering, but it is best to avoid topdressing before and after budding.

6. Insect diseases: sweet cedar is prone to mosaic disease, ball rot and so on. When planting, the soil and bulbs should be thoroughly disinfected, and the basin soil should be changed thoroughly every year. At the same time, attention should be paid to the control of aphids. 1500 times of omethoate or 90% trichlorfon can be sprayed at the initial stage of aphid occurrence.

Points for attention in Xiangxue orchid culture:

During the growing period, sufficient fertilizer and water are required, organic liquid fertilizer is applied every two weeks, and appropriate amount of compound chemical fertilizer can also be applied. The basin soil is required to be dry and wet, not stagnant water or too dry. The bulbs are usually sown in September, the flower buds begin to differentiate in early November, and the differentiation is completed in late November. After May of the following year, the leaves withered gradually and the corms entered the period of natural dormancy.

Xiangxue orchid in the process of indoor cultivation, there are often thin and weak plants, when drawing pedicels, it is necessary to support the flower stem to prevent the pedicel from bending and affect the ornamental value. In order to prevent its overgrowth, the way to promote "dwarfing" is to treat the seed ball with paclobutrazol before planting, which can achieve excellent results. Methods the stored seed balls were soaked in 80ppm's paclobutrazol solution for 15 to 20 hours before potted sherry in autumn, then washed with clean water, then put on the pot and watered normally. After treatment, Xiangxue orchid emerges neatly, the leaf color is dark green, the leaf width increases, the length decreases, and the fragrance is more intense after flowering.

The floral words of Xiang Xuelan:

The flower language of Xiangxuelan is: purity. Flower divination: your naive and sweet face is like a pure girl in a painting, which does not eat human smoke and fire, and at the same time does not know that people are sinister. When you hear the sweet words, you look powerless and indulge in a picturesque love, which is very dangerous. You should learn to protect yourself and be alert as soon as possible. Flower motto: you should know that behind love lies happiness and pain, sadness and regret.

The planting of Xiangxuelan introduces how to raise Xiangxuelan.

Fragrant Cymbidium, also known as freesia, calamus orchid, scissors orchid, etc., is a perennial bulb herb flower of Iridaceae. It is named for its pure white color and faint fragrance like orchid. Cultivation is mainly for viewing. It is cultivated in the open air all over the south and potted in various parts of the north. Potted plants or cut flower branches are often used to bottle and decorate indoors. Let's take a look at the breeding methods of fragrant sherry.

Growth habits of Xiangxue orchid

Xiangxue orchid prefers cool, humid and sunny environment, and its cold tolerance is poor. The suitable temperature for growth is 15: 20 ℃, and the lowest temperature for overwintering is 3: 5 ℃. The large temperature difference between day and night is beneficial to growth and development. The suitable temperature at night is 10: 15 ℃, and the daytime temperature should not exceed 20 ℃, otherwise the growth is poor. Like loose, good drainage, humus-rich soil. Under the condition of short-day sunshine, Xiangxue orchid is beneficial to promote flower bud differentiation, while long sunshine after flower bud differentiation can blossom earlier. The bulbs are usually sown in September, and the flower buds begin to differentiate in early November and complete in late November. the leaves wither gradually after May of the following year, and the corms enter the period of natural dormancy.

The breeding method of Xiangxue orchid

1. Sowing: Vanilla is usually collected in time after the seeds are mature from May to June, otherwise the capsule is cracked, the seeds are lost, and the seeds have no dormancy habits and can be sown immediately after harvest. The optimum temperature for seed germination was 15-20 ℃, and the germination time was about 21 days under dark conditions. When the seedlings had 5-7 leaves, the aboveground parts were withered and yellow, and the underground corms entered the period of high temperature dormancy. After dormancy, the seed balls can be planted and cultivated for 1 year, and then they can be used as flowering mother balls.

2. sub-ball: Xiangxue orchid can generally bear 4-6 seed balls around the cue ball, which can be dug up in the summer dormant period, stored after the ball is separated from the mother ball, and sown in autumn. The bulb cultivated as a cut flower requires a bulb with a stem circumference of more than 8 cm to ensure the quality of the cut flower. The method of cultivating bulbs is to dig up and store them during the summer dormancy period, and they can be planted in flowerpots in early August.

Culture method of Xiangxue orchid

1. Soil: vanilla prefers well-drained, loose and fertile sandy loam or cultivated soil plus 20%-50% humus. Before planting, to carry out soil disinfection, can be treated with methyl bromide 50g / sqm. After application, the rake is smooth, and the seeds can be sown every 5 to 7 days. Pot culture soil can be mixed with rotten leaf soil, pastoral soil, fine river sand and mature organic fertilizer.

2. Planting: the planting time of Xiangxue orchid varies with the planting type and flowers according to the requirements of the city. the common planting period is from September to October and the main florescence is from March to April. The cultivation was promoted from the first and middle of September to the middle and late November, and the cultivation was inhibited from January to March. The general plant spacing is 812 cm, and the planting density is 80,110 plants per square meter. The planting depth should be 1cm from the top of the bulb to the surface, and 2cm from the soil cover.

3. Fertilization: the bulb root of Xiangxue orchid is small, and the storage nutrition is limited, so liquid phosphorus and potassium fertilizer should be added in 2-4 leaves. Organic compost or coarse-grained organic fertilizer should be applied early before planting to improve soil fertility, soil looseness and aeration performance. The base fertilizer is mainly organic fertilizer, and some chemical fertilizers can also be applied properly, but the amount should not be too much to prevent physiological obstacles caused by the increase of salt concentration in the soil. Liquid fertilizer is the main topdressing.

4. Watering: Xiangxue orchid does not need a lot of water at the initial stage of potting, the basin soil should be dry and wet, and it can be watered once a week. By the beginning of February, when budding, the plant will grow rapidly and consume more water, so it is necessary to keep the basin moist. One month after flowering, the water supply should be gradually reduced. Water can be watered once every two days to prevent rotten balls, and the leaves can no longer be watered when the leaves are yellow at the end of February.

5. Temperature: cool environment was needed for root formation and flower bud differentiation. The root system grew best at 15: 18 ℃, the flower bud differentiation was the best at 12: 15 ℃, and the inflorescence grew fastest at 18: 20 ℃. Therefore, the inflorescence development could not be reversed when the initial planting temperature was kept at 15: 18 ℃, 5: 7 leaf stage, 12: 15 ℃ for flower primordium induction, and kept at this temperature for 4-6 weeks. Then heated to 16-17 ℃, the inflorescence elongated rapidly and entered the flowering stage.

6. Light: proper shading should be given during the seedling stage and flowering stage in the cultivation of fragrant blueberry. During the growing period of the first leaf, proper shading can reduce the ground temperature and promote the development of root system. Short-day treatment of about 10 hours before flower bud differentiation is beneficial to promote flower bud differentiation and increase the length of flower stem and the number of flowers and lateral ears on inflorescence. Properly prolonging sunshine after the completion of flower bud differentiation is beneficial to promote the good development of inflorescence and early flowering.

7. Diseases and insect pests: sweet cedar is prone to mosaic disease, ball rot and so on. When planting, the soil and bulbs should be thoroughly disinfected, and the basin soil should be changed thoroughly every year. At the same time, attention should be paid to the control of aphids. 1500 times of omethoate or 90% trichlorfon can be sprayed at the initial stage of aphid occurrence.
