How do spring orchids grow? Introduction of Cymbidium hydroponics method and conservation guide

Chunlan, also known as Dolan, is the oldest species of orchids in China. When it blossoms, it will give out elegant aroma. It is a kind of household flower that many people like to breed. Let's learn about the method of hydroponic culture of Chunlan.

1. Hydroponic culture method

Hydroponic cymbidium is a new cultivation method with water as medium and nutrient solution instead of soil. This method is simple and easy to learn.

(1) choose a special hydroponic flowerpot or brown wide-mouth bottle hydroponic orchid, use a special hydroponic flowerpot with no hole at the bottom and a double-layer net screen inside and outside, the culture medium is in the outer pot, and the inner basin is a grid sieve. The ribs between the meshes are fixtures for holding bulbs and orchid plants, such as stones or sponges. When transplanting the orchid plant, pull up the orchid plant with root, remove the old root, rotten root and excess root, and then rinse the root with clean water.

(2) the whole plant was disinfected once before entering the water and the concentration of the whole plant was 100 mg/I. After 10-15min of potassium permanganate solution, remove and rinse potassium permanganate solution with clean water.

(3) divide the roots into 2-3 groups and insert them into 2-3 sieve pots, as shown in the picture, so that the bulbs are close to the cross ribs in the middle of the sieve foramen.

(4) use one hand to straighten the orchid plant, and the other hand to hold the washed 3cmX 5cm pebbles around the plant and shake it slightly around the inner sieve, and the orchid plant will be fixed in the center of the inner sieve. Wash and fix with clean water again, fill the outer basin with water, and put the culture liquid of human orchid in the water [Yoshama Huayao].

2. Maintenance guidelines

(1) Light and temperature: Cymbidium prefers half-yin and half-yang, the environment with scattered light, the suitable temperature for growth is 20: 30 ℃, the plant is soaked in 1% potassium permanganate solution 10~15min, and then rinsed with clean water, the plants used for hydroponic culture are randomly and equally spare, and the seedlings are incubated in clear water for about a week, and then cultured in nutrient solution.

(2) watering: Cymbidium is suitable for growing in an environment with an air humidity of 70% to 90%. If the air is too dry, the orchid grows poorly, and the leaves are small and thin and dull. You can increase humidity by watering, Rain Water is the best, or you can use tap water and leave it for 1-2 days until chlorine volatilizes before use.

The above is the introduction of Chunlan hydroponics and maintenance guidelines. Chunlan hydroponics is simple and easy to operate, and the maintenance method is not complicated. Therefore, if you like Chunlan, you can raise it. Chunlan also has the effect of self-cultivation.

Winter potted flower conservation technology potted flower refers to the flower that exists in the form of potted plant; it can be a real flower or an imitation flower. Potted plants generally only mean fresh and alive. Potted flowers include bonsai, hydroponic culture, grass flowers, foliage, fruit, flowers and other potted flowers.

First, the maintenance temperature of indoor potted flowers: the indoor temperature should not be too high or too low in winter. If the temperature is too high, the flowers will wither easily, and if too low, it will affect the normal growth. Like warm potted flowers can be placed near the internal heat source or sunny place, more cold-resistant potted flowers can be placed near the shade or entrance. Humidity: potted flowers that like drought should be placed in places with strong indoor light and good ventilation, such as in the shade, they will cause overgrowth; potted flowers that like to be moist should be placed in places that are not easy to be exposed to the sun and have moisture, if the air is too dry, there will be the phenomenon of leaf tip yellowing. Ventilation: when there is plenty of sunshine at noon in winter, you should open the window properly to make the air circulate. Drive less or not on snowy days. While doing a good job in indoor hygiene, we should often spray water to the leaves to remove the dust on the leaves, so as to facilitate the breathing of plants. Residual flowers and withered branches should also be cut off in time. Second, winter potted flowers warm a large number of potted flowers can spend the winter in the greenhouse, and for a small number of potted flowers can be protected by making a simple greenhouse to keep warm. Simple greenhouse can be made of bamboo or iron scaffolding on the balcony or sun terrace, covered with plastic film, and covered with heat preservation in the evening. Indoors, a thin piece of bamboo or lead wire can be inserted around the basin to form a bow, about 10 cm higher than the plant, covered with transparent plastic film, tied up with a rope along the mouth of the basin, and put the potted flowers in a sunny place. If the weather is sunny and the temperature is high, the film can be removed at noon to make it ventilated to avoid decay. You can also leave a few small holes in the film to facilitate ventilation. There are water droplets in the inner layer of the film in the shape of cloud, indicating that the temperature and humidity are suitable. After watering, remove the film and cover it after the water evaporates for a period of time. The branches of the new cuttings can not be covered, because the wound is prone to mildew and rot before healing, causing death. Third, water and fertilizer watering of potted flowers in winter: the watering time for winter potted flowers should be from 10:00 to 3 p.m., and the water temperature should be roughly close to the soil temperature and air temperature. Too high or too low will stimulate the potted flowers. In serious cases, it will cause fallen leaves, rotten roots and even death. The frequency of watering potted flowers in winter and the amount of water each time are less than those in other seasons, generally indoor potted flowers are watered once a week, and balcony potted flowers are watered twice a week. Each watering should be thoroughly watered, avoid watering "half-hanging water", because the root absorption function is weak in winter, too wet is easy to cause rotten roots, too dry will make the absorption function of hairy roots dehydrated and die. In winter, in addition to maintaining the basin soil by watering, the branches and leaves of the plant should be properly sprayed. For example, to view the leaves of tortoise back bamboo, pineapple, asparagus, spring feather, rubber tree, hulk, green apple, ruby and so on, spraying water can not only wash the dust on the leaves, but also make the leaves look more clean and fresh. For camellia, orchid, plum blossom, wax plum, spring, cyclamen, etc., to keep the plant moist, it can not only make the branches and leaves vibrant, but also accelerate the expansion and opening of the bud; for flowers or inflorescences that have already blossomed, it should be changed from water spray to spray to prevent the flowers from withering prematurely. For Tianzhu, Firethorn, bergamot, kumquat and so on, spraying water can promote Ye Xian Guo Yan. Fertilization: it should be different according to the type of potted flowers. Dormant potted flowers, such as pomegranate, hanging bell crabapple, mulberry, cactus, bulbous begonia, Magnolia, Milan, Zhulan, jasmine, rose, peony, Luohansong, etc., do not need to be fertilized. Foliage potted flowers can apply appropriate amount of compound fertilizer, such as tortoise back bamboo, spring feather, peach leaf coral, goose palm wood, rubber tree, one-leaf orchid, asparagus, hydrangea pine, etc., a small amount of granular fertilizer can be buried in the soil. Potted flowers such as cyclamen, camellias, wax plums, plum blossoms, chrysanthemums, primroses, magnolia, etc., can be treated with 0.2% potassium dihydrogen phosphate solution, and stop fertilization after opening the bud. View the fruit to increase the application of calcium superphosphate granule fertilizer, such as bamboo, kumquat, bergamot, winter coral and so on. The condition of fertilization is that the room temperature must be higher than 10 ℃, otherwise the fertilizer is not easy to be absorbed. How to grow flowers in spring?

Spring is the season of recovery of all things. In such a beautiful season, there must be many beautiful people who go to the flower market to buy one or two pots of their favorite flowers to decorate their beloved rooms. In the spring breeze, the flower gradually stretches its lazy waist and releases the green that has been oppressed for a long time. I believe that it will not only bring you the wind and gorgeous scene of spring, but also bring you some surprise and longing every day. Although the flowers are beautiful, they need to be cared for. Only under your careful care can the flowers blossom more beautifully and bring you greater harvest.

Spring returns to the earth, and the temperature rises gradually, but the middle and lower reaches of the Yangtze River are still in the alternating period of winter and spring, and sometimes there will be chilly weather in spring. Therefore, we should not only be prepared to "go out" of cold potted flowers, but also strengthen the maintenance and management of other potted flowers.

What kind of flowers should be raised in spring?

Peach blossoms, begonia, pear blossoms, Magnolia, Tripterygium, forsythia, Huangxin and most camellias are in full bloom. Chunlan, Ruixiang, crab claw orchid, Yingchun, tea plum, wax plum and so on withered one after another. The famous camellias, which are in full bloom, can be moved to the ventilated part of the window and moved to a warm place outside for shelter at night. However, in case of cold weather, spray 800 times of the new high-fat film liquid to enhance cold resistance, and move into the room, which can prolong the flowering period.

1. Rich bamboo

Liliaceae is an evergreen upright shrub, which is very suitable for indoor hydroponic flowers. The leaves of Fugui bamboo are green, the stems are straight and round like bamboo. Leaves ovate, apex pointed, petiole base clasping. It is a very shade-tolerant plant. It still grows well and is tall and strong under weak light conditions. Can be placed indoors for a long time to watch the leaves, do not need special maintenance, as long as there is enough water, it can grow vigorously. When hydroponic culture, the rich bamboo stem will be cut into small segments of more than 20 cm as cuttings in water, as long as the cuttings can be soaked in water, they can take root and survive.

2. Hanging orchid

Perennial evergreen persistent-rooted herbaceous flowers of the family Liliaceae having clusters of leaves linear with longitudinal yellow-and-white stripes on the margin or in the middle. In summer and autumn, slender, flexible and drooping stolons are drawn from the leaves, tender leaves and aerial roots germinate at the top or nodes, and white flowers bloom. The orchid can be raised in indoor water, which can not only purify the air, but also has the advantages of beautiful appearance and simple management. Dig out the potted orchid, go to the root soil, cut off the old root and rotten root, leave the fibrous root, put it in a container bottle, fill the bottle with water and flower nutrient solution, and let the root of the orchid grow in water.

3. Asparagus

Perennial evergreen herbaceous flowers of the genus Liliaceae. The stem is thin and weak, and the branches are slender and leafy, spreading horizontally. The flowers are small and white. Berries globose, black. After the fruit is ripe, it shows a little red in the thick green cluster, elegant and lovely. Plant strong negative tolerance, placed at the head of the bed, table case, elegant and generous, is a good indoor flower. Asparagus is also an ideal foil material for cut flowers. In recent years, water-raised asparagus has been successfully developed, which is even more elegant in the room.

4. African chrysanthemum

Compositae perennial root herbs, large flower diameter, rich flowers and colors, often blooming all the year round. Like warm, sunny and well-ventilated environment, is a semi-cold-resistant flowers, like fertile and loose. African chrysanthemum is a good variety of cut flowers, which can be cultured in water for a long time and highly ornamental, and it is also a good hand at absorbing formaldehyde.

5. Hyacinth

Also known as foreign daffodils, belongs to the hyacinth genus of Liliaceae, perennial herbs, bulb spherical or oblate, outer coat flag is purplish blue or white, etc., basal leaves, leaves thick, banded lanceolate. Flower stem extracted from the middle of the leaf stem, raceme, flower appearance delicate, colorful, dazzling, pleasant fragrance. Sex likes a sunny and cool and humid environment, which is not only suitable for potted plants, but also suitable for water culture. When cultured in water, the bulb is placed in hydroponic nutrient solution with clean appearance and strong ornamental.

Second, what kind of work should be done to grow flowers in spring?

1. Prepare for "leaving the room"

Starting from late March, when the weather gradually gets warmer, the windows can be opened during the day for several days (7 to 10 days), so that these cold potted flowers living in the room can directly accept the outdoor sun and air, making them gradually adapt to the external environment. After that, on cloudy and rainy days, some flowers with stronger cold tolerance, such as cycads, rubber trees, jasmine, Chunlan, Zhu Dinghong, calla lilies, mulberry, cyclamen, etc., are moved outside and placed in a warm place. If there is a cold and low temperature at night, you should still move back indoors to take shelter from the cold, and still put it outside the next day.

Another method of "getting out of the room" is to move the above-mentioned cold potted flowers out of the room for one to two hours a day from the end of the day, and then move back indoors. After 5 to 7 days of moving in and out, I finally put it outside on a rainy day. For Brazilian wood, rich trees, all kinds of evergreen flowers and leaves, which have poor ability to keep out of the cold, it is appropriate to "leave the room" from late April to early May. If there are many potted flowers in the family, they can be treated differently before and after the Qingming Festival, and "go out of the room" in batches.

2. Early spring management

For the pot flowers soon after coming out of the house and the cold-resistant pot flowers originally placed outside, pruning and pruning, turning the pot and changing the soil should be done in time before germination and growth. In addition to turning the pot to change the soil, the magnolia, Baizhilian and lotus that bloom in May should all be fertilized once and sprayed with flower Zhuangtiling solution to make it blossom at that time. Spring and plum blossoms should be pruned after blossom. In addition to cutting off withered branches, disease and insect branches, over-weak branches and over-dense branches, annual branches should be strongly cut at 2 m / m 3, which can make the germinated new branches stout and bloom densely. Kumquat should undergo a heavy pruning before sprouting in spring, first removing cross branches, introverted branches, disease and insect branches and withered and weak branches, and then pruning the remaining branches according to the principle of weak pruning of strong branches and strong pruning of weak branches, usually leaving 5 buds of sturdy annual branches and 2-3 buds of ordinary branches, which can promote multiple sturdy spring shoots and facilitate flowering. Do a good job in turning the pots of rhododendron, spring, plum blossom, camellia, Daphne and other flowers and evergreen broad-leaved trees. The pot of rose is the most suitable at this time, and the pot-planted lotus is the best in late March.

3. Reproduction work

The cuttage seedlings that can be raised in March are Luohansong, pomegranate, Fusang, Yingchun, poinsettia, Tamarix, grape, ivy, silver willow, firethorn and so on. The cutting rod incision can be trimmed with new high-fat membrane mother solution to prevent bacteria from invading. (note: do not wrap it with plastic anymore). The flowers that can be sown or planted in late March are poinsettia, cockscomb, wind fairy, sunflower, wild goose red, thousand-day red, canna, dahlia, gladiolus and gentleman orchid and other flowers. The seeds can be treated with new high-fat membrane.

Matters needing attention for family flower cultivation in spring

1. Move the basin

In general, flowers and green plants are planted in pots when they are purchased, and it is best to plant them in the original pot after taking them home, and do not move the pot easily, especially at this time, when the weather is suddenly warm and cold, many plant roots are deeper, and as soon as you move the pot, it will cause the flower root to absorb nutrients unfavourably, resulting in plant death. When buying, we should also pay attention to whether the potted flowers have been moved when they are sold. Generally, the soil that has not been moved is hard and caked, while the soil that has been moved is scattered. Of course, some flowers have been planted for many years, and you can choose to move the pot from March to April, because the climatic conditions of these two months are conducive to the survival and growth of flowers.

2. Watering

Ornamental fruit plants, such as bergamot and kumquat, should not only keep the potted soil moist, but also spray water on leaves, buds and fruits, so as to make their leaves green, flower buds expand rapidly and fruits colorful. Buy back the Cymbidium and poinsettia cultivated in the greenhouse, because the temperature and humidity in the original environment is very different from that in the family, if you do not spray water on the leaves often, it will often cause the leaves to shrink and dry. For all kinds of pineapple flowers, such as Geely Star and Gao Hongxing, if the room temperature is lower than 10 to 15 degrees, not only watering should be controlled, but also too much water should not be injected into the leaf tube to prevent heart damage.

3. Fertilization

Camellia, tea plum, rhododendron, gentleman orchid, red plum, cymbidium, etc., as long as the room temperature is not less than 15 degrees, compound fertilizer can be applied once in 15 to 20 days. All forms of topdressing should be stopped for tree stumps and potted foliage plants that have entered a dormant state.

4. Pruning

From March to April, for potted ornamental plants, the withered branches and yellow leaves and the branches and leaves infected with diseases and insect pests should be cut off together and destroyed. Some varieties, such as rubber trees, happiness trees, etc., need to "hit the head", that is, cut off the tallest tender head, the length of which is two or three centimeters, and the section can be disinfected with pot bottom ash after cutting.

5. Guard against cold

Because it is still warm and cold season, according to different ornamental plant species can bear the lower temperature to determine the potted plants shelved on the balcony, before the cold wave, must move into the indoor to avoid the cold, or directly above the plant to build a double-layer plastic shed to protect against the cold.

6. Disease and pest control

Shell insects and whitefly on potted plants should be wiped off with a wet cloth in time, while aphids on potted plants can be killed with tobacco (shredded) soaking water.

Flowers can make people feel happy, and beautiful flowers are more pleasing to the eye. Take good care of those flowers.

Fourth, the common sense of growing flowers in spring

1. Flowers and plants grow vigorously in spring, with large evaporation and high consumption, so water and fertilizer should be kept up; when the basin soil is dry and cracked, it should be watered in time; fertilizer should be applied once a week or half a month; and the soil should be loosened before watering and fertilization.

2. After winter, withered branches and fallen leaves should be pruned in time, and pillars and bindings should be added to some vines and flowers in time, so that the branches and leaves are evenly distributed and ventilated.

3. Evergreen flowers are most likely to survive by changing pots before sending leaves, so choose to change pots or put on pots on cloudy days.

4. Pests should be killed in time, especially when aphids occur.

5. Spring is a good time for flower breeding. Flowers that bloom in summer and autumn should be sown in time, bulbous flowers should be planted in time, and perennial flowers should be cut.

Finally, I would like to give you a "recipe for growing flowers in spring".

The greenhouse is getting warmer in early spring, and the window ventilation should be slow.

Open the window at noon and close at night to prevent the temperature difference from being too wide.

Potted flowers should come out of the greenhouse for the first time when the temperature is stable.

Spring gentle help flowers grow, negative flowers also need to bask in the sun.

When you first come out of the greenhouse, you are afraid of the dry wind. Don't forget to build the greenhouse on windy days.

Potted flowers are watered with spring water for the first time, and too much water is easy to "support" and destroy.

Nitrogen fertilizer should be added to promote budding, and it is safest to avoid strong and light nitrogen fertilizer.

If potted flowers are to grow well, it is most important to change pots in early spring.

Do not delay transplanting and changing pots before dormancy and recovery of flowers and trees.

If flowers bloom in early spring, change pots should wait for flowers to bloom and fail.

Stop watering before changing the basin, and the soil in the basin is not fragile.

Change the pot for planting flowers, and cut the old roots properly.

It is ideal to plant flowers in sunset, such as sunset in sunny days.

Do not apply fertilizer to newly planted flowers and trees, and avoid pouring water immediately.

During the slow seedling period, the soil is too wet, the root is easy to rot and the whole plant dies.

Do not hesitate to prune the potted plant, and remove all the branches and leaves that hinder the beauty.

In order to promote the early differentiation of flower buds, stop applying nitrogen fertilizer to increase phosphorus and potassium.

Egg shell fish-scale chicken duck feathers, mature application of pregnant flowers.

Urge the flower season to water carefully, too wet and dry is easy to drop buds.

Do not apply fertilizer during flowering, basin soil slightly wet avoid flood.

The plant is close to the germination stage, and cutting grafting is the most suitable.

The ground temperature is stable and frost-free, and it is appropriate for flower sowing.

Sowing and covering the soil should be careful, equivalent to three times the depth of the seed.

If you want the seedlings to grow well, shading and moisturizing is the most important.
