Who has information on family flower cultivation? Please give it to me before April 7th.

The scents of roses, carnations, lilies of the valley, violets, roses, osmanthus flowers and other plants have obvious inhibitory effects on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.

Cactus and other succulents native to tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, increasing the concentration of negative ions in indoor air.

Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air.

Climbing plants such as Parthenocissus tricuspidata, grape, morning glory, wisteria, rose, etc. Planting around the house can make it climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.

Lilac, jasmine, rose, violet, mint and other plants can make people relax, feel happy, help sleep and improve work efficiency.

Flowers should mainly beautify the environment. Good flowers can not only enjoy the sight, but also purify the air. In fact, different flowers should be placed in different places, and some flowers are still not suitable for entering the house, otherwise it will cause air pollution.

Aromatic function of common flowers

Roses are sweet: relax nerves, relieve physical and mental fatigue, and help to treat nervous system diseases.

Tulip: It can relieve eye fatigue and irritability.

Orchid fragrance: relieving lung heat, resolving phlegm and relieving cough is good for people with neurasthenia, but it should not be too strong, otherwise it will also cause dizziness.

White orchid fragrance: it can sterilize and purify the air.

Chrysanthemum flower fragrance: it can clear away heat and dispel wind, clear liver and improve eyesight, and can be used as an auxiliary treatment for headache.

Clove: It has obvious air purification ability and strong sterilization ability. Putting cloves indoors can prevent infectious diseases to a certain extent, but its fragrance is rich and it is not suitable to smell, otherwise it will make you dizzy.

Narcissus: It can make people feel quiet and warm.

Clever flower arrangement in the hall can prevent diseases ... >>& gt Three kinds of plants are suitable for indoor display.

Experts pointed out that indoor flowers should be planted with flowers that can absorb toxic gases, purify the air or sterilize, and some flowers themselves have the function of preventing and treating diseases. For example, chrysanthemum and wintersweet have the ability to absorb sulfur and hydrogen fluoride, and the volatile oil secreted by thyme and clove has bactericidal effect. Jasmine, Milan, osmanthus, crape myrtle, rose, rose, etc. It can emit volatile oil with bactericidal effect, while Ren Mei gum and honeysuckle have a strong absorption effect on fluorine, and so on.

Don't plant flowers in the ward and bedroom at night.

Many flowers have the function of purifying the air and promoting health, but if you keep some flowers at home, they will become the source of disease or the "killer" who leads to the recurrence and aggravation of old diseases. Therefore, experts suggest that you must know the nature of flowers before raising them. In case flowers are kept at home, your body will have problems.

Patients should not keep potted flowers indoors-because the soil in the flowerpot will produce fungal spores. When they spread into the air, they can easily invade people's skin, respiratory tract, external auditory canal, meninges and brain, causing infection, which is very harmful to patients with existing diseases.

Flowers should not be placed in the bedroom at night-because most flowers absorb carbon dioxide and release oxygen through photosynthesis during the day, but at night, it is just the opposite. Therefore, it is best not to put flowers in the bedroom. Flowers planted during the day will be moved out at night, at least not in the bedroom, so as not to affect people's health.

Too many flowers will harm your health ... >>& gt Flowers that can't be ignored in the room.

Some medical experts have done experiments and tests, and the results show that people who often smell flowers will have a certain impact on their mood and health. Chemical experts believe that the fragrance emitted by flowers consists of dozens of volatile compounds, including aromatic esters, alcohols, aldehydes, ketones and other substances. These substances can stimulate people's respiratory center, thus promoting people's respiratory function. If people breathe the fragrance beneficial to human body, they can make the brain get enough oxygen, regulate people's nervous system, promote blood circulation, and make energy, thinking and vitality reach a very high level. Therefore, flower therapy and aromatherapy came into being.

Experts pointed out that the fragrance of flowers can not only cure diseases and protect health, but also cause diseases and harm people's health. The fragrance of flowers in the air is too strong, and the oxygen content is relatively reduced, which will stimulate people to hyperventilate, reduce the oxygen content in the blood, and cause symptoms such as headache, dizziness and nausea. Some people with allergic constitution will be stimulated by some pollen, resulting in allergic asthma and allergic rhinitis. For example, orchids can help relieve hot cough, and may also play a catalytic role. The smell of orchids is too strong, which makes people feel too excited and dizzy The fragrance of lilies is exciting, but if it lasts too long, it will make people dizzy and may also make people insomnia.

Common sense of family flower cultivation

First, the bedroom flowers "three appropriate"

We should cultivate 1 flower with strong medication ability. Some flowers can absorb a certain concentration of toxic gases in the air, such as sulfur dioxide, nitrogen oxides, hydrogen fluoride, formaldehyde, hydrogen chloride and so on. According to research, Chimonanthus praecox can absorb mercury vapor; Pomegranate plants can absorb lead vapor in the air; Snapdragon, Canna, Morning Glory, Gladiolus, Dianthus, etc. The highly toxic sulfur dioxide can be converted into nontoxic or low toxic sulfate compounds through the oxidation of leaves; Narcissus, mirabilis jalapa, chrysanthemum and Saxifraga can transform nitrogen oxides into protein in plant cells; Chlorophytum, aloe and Eupatorium adenophorum can absorb a lot of indoor formaldehyde and other pollutants, and eliminate and prevent indoor air pollution.

2. It is advisable to raise flowers that can secrete fungicides. Germicides secreted by flowers such as jasmine, clove, honeysuckle and morning glory can kill some bacteria in the air, inhibit the occurrence of diphtheria, tuberculosis, dysentery and typhoid, and keep the indoor air clean and hygienic.

3. Flowers with complementary functions should be cultivated. Most flowers mainly carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen. Breathe in oxygen at night and release carbon dioxide. Cactus, on the other hand, releases carbon dioxide during the day, absorbs carbon dioxide at night and releases oxygen. Keeping flowers with complementary functions in a room can not only make them mutually beneficial, but also balance the contents of oxygen and carbon dioxide in the room and keep the indoor air fresh.

Second, the "three taboos" of growing flowers in the living room

1 Avoid raising more flowers with strong fragrance and pungent smell. Such as orchids, roses, Chinese roses, lilies, cordate telosma and so on. , can send out a strong fragrance. A pot in the room is full of fragrance, but if there are too many fragrant flowers in the room and the fragrance is too strong, it will cause people's nervous excitement, especially if people smell it in the bedroom for a long time, which will cause insomnia. The gas emitted by Christmas flowers and evergreens is not good for people; The particulate matter emitted by tulips and hydrangeas is exposed for too long, and the skin will be allergic and itchy.

2. Avoid placing too much. At night, most flowers release carbon dioxide and absorb oxygen to compete with people. Most of the rooms at night are closed, and the air is not well circulated with the outside world. Excessive indoor flowers will reduce the indoor oxygen concentration at night and affect the quality of sleep at night, such as chest tightness and frequent nightmares.

3. Avoid putting poisonous flowers indoors. Such as oleander, its stems, leaves and even flowers are toxic in spring, summer and autumn, and its milky juice contains an oleanolide, which will be poisoned if eaten by mistake; The bulbs of daffodils contain Latin toxins, which can cause vomiting and other symptoms if children eat them by mistake. The juice of leaves and flowers makes the skin red and swollen. If the juice is eaten by mistake, it will hurt the eyes. Too much exposure to mimosa can easily lead to sparse eyebrows, yellow hair and serious hair loss.

Therefore, we should know about Shang Huashi's relevant scientific knowledge and bring health and happiness to ourselves and our families.

Third, the "six precepts" of family flower cultivation

Nowadays, it is more and more common to raise flowers at home, but many flower lovers make their flowers dull and lifeless because they have no ideas. What's the problem?

A careless flower, like people, is alive and needs careful care. Many flower farmers lack due care and diligence for these beautiful lives. First, lazy, unwilling to study flower cultivation knowledge, willing to be a layman for a long time, and illegal management. Second, lazy hands, unwilling to spend too much time and energy on flowers. After the flowers entered the house, they were left out in the cold, hungry for a long time, and suffered from pests and diseases. In this way, even the best flowers will gradually wither. So lazy people can't raise flowers.

Contrary to the above situation, some flower farmers love flowers so much that their fingers itch when they don't play for a while. Some watering and fertilization are irregular, so they are watered when they think of it, so that flowers die from waterlogging and fertilization; Some move flowerpots around casually, and they can move to several places a day, which makes the flowers have to adapt to the environment frequently and disrupts the normal growth law. In the long run, it's strange not to toss the flowers to death. There are several potted flowers at home, and it is understandable to like them, but flowers have their own growth rules like people. If they are often disturbed when they need to have a rest, they will naturally feel tired and grow badly.

Some flower lovers believe that famous flowers have high ornamental value and great market profit, so it is necessary to raise them. Under this psychological control, they spend a lot of money to buy famous flowers and trees everywhere. The result is often due to the lack of good conservation conditions and management techniques, flowers die soon after being bought, which not only wastes precious flowers, but also wastes money. This is a conceptual misunderstanding. The correct way should be to start from ordinary and low-grade species and gradually explore the rules and skills of flower cultivation. After reaching a certain technical level, we will gradually purchase more expensive types, so as to grasp the success.

Some flower farmers are desperate under the temptation. They are insatiable, regardless of any variety. When they see it, they move home, which not only brings difficulties to management, but also brings some flowers that are not suitable for cultivation to their homes, polluting the environment and damaging their health. For example, flowers with poisonous juice are easy to be poisoned when people touch them. The smell of some flowers has an impact on people's nervous system, which is easy to cause poor breathing and even allergic reactions. Plants with sharp thorns on the outside also pose a certain threat to human safety, and so on. In short, family flowers should not be greedy for perfection, but cultivate varieties with small plant type, beautiful appearance and no harm to human body.

Some flower growers are impetuous, they have no theme, and the flowers at home turn around like lanterns. This is a big taboo for growing flowers. First, the species changes too fast and the planting time is short, which is not conducive to cultivating beautiful plants and ornamental flowers and trees. Second, tasting every kind of flower is not conducive to the improvement of flower cultivation level, and in the end it is still a flower blindness. Therefore, flower growers can only gain something if they choose one or two kinds of flowers correctly and focus on cultivating them.

The concept of "six precepts" is not new. Nowadays, new knowledge and technologies are emerging in the flower cultivation industry, but most flower growers still stick to the traditional maintenance methods, and are not good at using new technologies and equipment such as soilless culture, odorless flower fertilizer and various flower devices in the aspects of flower device use, water and fertilizer management and seedling cultivation. As a result, family flower cultivation is unsanitary, unsightly, novel and has great side effects.

First of all, the benefits of planting flowers

Flowers, with their gorgeous style, decorate nature extraordinarily beautifully and give people beautiful enjoyment. Raising flowers can enrich and regulate people's cultural life, add interest, cultivate temperament and improve health; It can also increase scientific knowledge and improve cultural and artistic literacy. Planting flowers can beautify the motherland, protect and improve the environment, purify the air, and let people work and study in a beautiful environment and live a better life. Planting flowers is not only for viewing, but also has many important economic values. Flowers are an important part of Chinese herbal medicine. Honeysuckle, chrysanthemum, wintersweet, hibiscus, azalea, rose and lotus are all common Chinese herbal medicines. Fragrant flowers are widely used in food and light industry. For example, Osmanthus fragrans can be used as food flavor and wine making, Jasmine, Prynne, Daidai and Zhu Lan can be used to smoke tea, Chrysanthemum can be used to make high-end food and dishes, and White Orchid, Jasmine, Rose, Chimonanthus praecox and Narcissus can be extracted.

Second, the knowledge of buying flowers

Do not buy the following flowers.

1. If you see new soil in the pot when you buy flowers and the stem moves as soon as it is pulled out, then the pot of flowers must have grown new roots not long after it was put into the pot. Such flowers are easy to die after being bought back. The reason is that some business households directly mix immature organic fertilizers into the soil in pursuit of economic benefits. Once these fertilizers are fermented, the roots of flowers will be burned out. Sometimes in order to save labor or seize time, they plant the flower roots without any arrangement, and even put the flowers and trees that are too damaged to survive into pots for listing. If you buy such flowers carelessly, most of them will be difficult to survive.

2. Two or more flowers planted together. Some business households seize the buyer's exuberant psychology of flowers, plant two or more unsatisfactory flower seedlings together in flowerpots and sell them to inexperienced buyers for profit. After this flower is bought back, the branches and leaves will become thinner, weaker and yellow day by day, and the flower will become smaller and smaller. The reasons are insufficient nutrition, too many roots in the basin, easy hardening, poor drainage and ventilation, and the roots may rot and die. Of course, special combination potted plants are not included. In summer or winter, flowers without soil, in hot summer, the temperature is very high, the leaves of flowers and trees evaporate quickly, and the roots of flowers and trees in new pots are more or less damaged, so it is difficult to absorb water from the soil in a short time. Only by bringing the original soil can safety be achieved.

Get through this transition period, otherwise it will wither first and then die slowly. In winter, the weather is cold, flowers and trees grow slowly, and some flowers and trees even go into dormancy. At this time, flowers and trees without soil balls are bought home from the market, and when watered, they may suffer from freezing damage (especially roots), hinder plant growth and even lead to death. Even if it is not frozen, it is difficult for flowers and trees to grow new roots because of the low soil temperature, while the old roots can not germinate for a long time and are prone to decay and necrosis. Special attention should be paid to areas such as the Yangtze River Basin where there is no heating in winter.

3. Flowers with roots and no stems and leaves Some individual vendors dig wild vines and miscellaneous roots up the mountain to pretend to be flowers and trees for sale in autumn and winter. Because there are no stems and leaves, it is difficult to identify them. In order to keep moisture, they wrapped in moss and took some strange flower names to deceive inexperienced buyers. Some people are greedy for cheap, but nine times out of ten they don't blossom when they buy long leaves.

4. Flowers of various colors can be displayed on the screen. In order to make a profit, a few unscrupulous traders put fake flowers in various colors on some plants that can't bloom, and then take pictures and take some foreign flower names to deceive friends who are beginners in flower cultivation. These flower vendors who set up stalls change places as soon as they make a move, and it is difficult for fooled buyers to find out.

5. Tie branches and leaves into flowers and trees of various shapes with fine wire. In order to get a good price, the business owner intends to tie all branches and leaves of evergreen trees such as pine and cypress with fine wire into various animal shapes, and then take them to the market to make bonsai and sell them at a high price. This potted flower was beautiful at that time. As time goes on, as the plant grows, its shape will change. Moreover, binding all branches and leaves at the same time will not only affect photosynthesis, but also easily cause pests and diseases, which is very unfavorable to plant growth.

6, cactus flowers with small frozen spots on the stems or balls In the early spring, it is often seen that individual vendors sell cactus flowers at low prices. Some buyers don't look carefully and buy more than a dozen or eight trees at a time, and there are not a few problems as a result. The reason is that the cactus in winter is vulnerable to slight frostbite, and pale green frozen spots smaller than rice grains appear on the stems and balls. On the surface, there is no problem, but in essence, the internal tissues of plants have been greatly damaged. If no measures are taken after such flowers are bought back, the spots will become bigger and bigger, the plant will gradually become translucent, and finally the whole plant will die.

Third, the spring maintenance of family potted flowers

One year's plan lies in spring, and the management and maintenance of family potted flowers in spring is very important, and the following three aspects should be done well.

1. Cultivate the seedlings. Roses, geraniums, pomegranates, winter jasmine, etc. You can use strong branches for cutting in spring. Rhododendron and jasmine like acidic soil, so we can cut 5- 10 cm of new branches, remove the lower leaves and leave 3-4 upper leaves for cutting. Cuttings can be made of black mountain mud, vermiculite or yellow sand, and they can take root after being sprayed moderately and kept at a certain humidity, generally about 1 month. Orchid, agave and chlorophytum can be propagated by ramets or creeping branches respectively in early spring.

Spring sowing seeds of herbs, such as asparagus, colored pepper, mimosa, impatiens, a bunch of safflower, morning glory and malachite, can be broadcast or on demand. Sowing method: first fill the basin with soil, slightly compact it, then sow it, and then cover it with fine soil. After sowing, water, generally put the flowerpot into the basin, and let the water slowly seep out from the bottom of the basin. Most of them can germinate 1-3 weeks after sowing, and then move the pot to the sun after germination. After the seedlings grow 2-3 leaves, they can be transplanted separately. Be careful not to hurt the roots or break the stems when transplanting.

2. turn over the pot and change the soil. This is a method of fertilizing potted flowers in spring. Generally, small pots are turned once a year, and large pots are turned once every 3-4 years. Tall plants need to be replaced with big pots. Some roots grow too densely or have dead roots and rotten roots, which need to be pruned properly. Generally, you should pour the water thoroughly for the first time after turning the pan, and then put it in a cool place. After seeing the soil dry, water it. Generally, after the new roots grow, they are watered normally and moved to the sun.

Step 3 trim. According to different plants. Rhododendron, Yingchun, etc. Should not be trimmed too much. Pomegranate, rose, etc. You can cut off dead branches, injured branches or overgrown branches in early spring to promote the growth of flowers. When changing pots, jasmine should remove the old leaves and let it grow more new branches. Climbing lianas such as Parthenocissus tricuspidata, Radix Aucklandiae, Wisteria, and roses can be pruned, so that the leaves can receive as much sunlight as possible and grow vigorously.

Be careful not to move potted plants outdoors too early in early spring to avoid being destroyed by cold air. Watering can increase with the increase of temperature, and master the blend of dry and wet.

Fourth, family potted flower summer maintenance

1. Water the flowers In summer, the flowers are vigorous and consume a lot of water, so water the flowers every morning and evening in summer.

2. Build a frame to block all potted flowers. In summer, you have to put up a shelf and put a reed curtain to shade them and let them spend the hot summer safely.

3, pay attention to ventilation indoor flowers, when the temperature exceeds 30~C, it is necessary to pay attention to ventilation, open the window, let fresh air flow into the room, heatstroke prevention and cooling.

4, moisturizing and cooling In summer, you can cover some grass on the basin soil so that the sun does not directly illuminate the basin soil, thus reducing the temperature of the basin soil and preventing the water in the basin soil from evaporating too fast; You can also use a sprayer to spray the leaves of flowers wet, and at the same time spray the surrounding areas wet to reduce the temperature and increase the humidity. This is of great benefit to some flowers that like cold.

Five, family potted flower autumn maintenance

1, strengthen water and fertilizer management. After beginning of autumn, the weather became colder. For some foliage flowers, such as asparagus, chlorophytum, cycad and so on. Generally, dilute liquid fertilizer is applied once every half month to keep the leaves green and improve the ability to keep out the cold; Used for chrysanthemum, camellia, azalea, etc. When flowers bloom once a year, liquid fertilizer mainly containing phosphate fertilizer should be applied in time to ensure sufficient nutrients to make them bloom more and more; For roses, Milan, jasmine, etc. If it blooms many times a year, sufficient fertilizer should be provided to make it bloom continuously; For some ornamental flowers, such as kumquat, bergamot, pomegranate and so on. , should be applied 1-2 times of dilute liquid fertilizer mainly phosphate fertilizer. With the gradual decrease of temperature, other flowers should be watered less except autumn sowing grass flowers that bloom in autumn and winter or early spring, so as to avoid excessive water and fertilizer, resulting in excessive branches and leaves, affecting flower bud differentiation and freezing injury.

2. Sow in time in autumn, harvest mature flowers and trees in autumn, and sow tulips, Erythrina, snapdragon, etc. Sow seeds in time, especially those that are easy to lose germination ability, in autumn, combined with pruning and cutting flowers and trees. Such as cut rose, rose, rose, etc. The survival rate is high.

Six, family potted flower winter maintenance

Different kinds of flowers have different growth habits, so different management measures should be taken to ensure their safe wintering.

1. Overwintering of deciduous woody flowers: Most deciduous woody flowers are native to temperate regions, such as pomegranate, honeysuckle, rose, peach blossom, and winter jasmine. They usually sleep in winter, so the room temperature can be controlled at around 5℃. If there is a balcony or a small courtyard, potted Chinese rose, peach, pomegranate and honeysuckle with strong cold resistance can be placed behind the balcony or in the corner of the courtyard, and covered with plastic film to make them safely overwinter.

2. Overwintering of evergreen woody flowers: such as oleander, kumquat and osmanthus. , are in a semi-dormant state, the temperature is generally controlled above 0℃, in order to spend the winter safely. For Milan, jasmine, hibiscus, gardenia, etc., it should be placed in a sunny place. The indoor temperature should be kept at about 65438 05℃. If the temperature is too low, flowers will die.

3. Biennial herbaceous flowers overwinter: such as Four Seasons Spring, Colored Grass, calceolaria, etc. If the room temperature is kept between 5℃ and 15℃, they can grow normally. For perennial herbaceous flowers such as asparagus, impatiens balsamina, geranium, begonia, etc., they can grow well at room temperature of 10℃-20℃ if the sunshine is sufficient. For the dormant herbaceous flowers such as Clivia and Oncidium in winter, it is enough to keep the room temperature at about 5℃ and give them proper illumination, with the illumination not exceeding 8- 10 hour every day, and strengthen the management of fertilizer and water, so that they can bloom in two months.

Seven, a few tips for flower cultivation

1. How to judge whether potted flowers are short of water?

(1) Flapping method: Gently pat the upper middle wall of the flowerpot with your knuckles. If the sound is crisp, it means that the soil is dry and needs to be watered immediately; If there is a dull voiced sound, it means that the soil in the basin is wet and you can temporarily stop watering it. (2) Visual inspection method: use eyes to observe whether the surface color of the basin soil has changed. If the color becomes lighter or grayish white, it means that the basin soil is dry and needs watering; If the color becomes dark or dark brown, it means that the soil in the basin is wet and can be watered temporarily. (3) Fingering: Gently insert your fingers into the basin soil about 2 cm deep and touch the soil. When it feels dry or rough and hard, it means that the basin soil is dry and needs to be watered immediately; If you feel slightly wet, delicate and soft, it means that the soil in the basin is wet, so don't water it. (4) Kneading method: twist the pot soil with your fingers. If the soil turns into powder, it means that the basin soil is dry and should be watered immediately; If the soil is flaky or granular, it means that the basin soil is wet and watering can be temporarily stopped. All the above methods are based on experience and can only tell people the dry and wet conditions of the soil in the basin. If you need to know exactly how dry and wet the basin soil is, you can buy a soil hygrometer, insert the hygrometer into the soil, and you can see the words "dry" or "wet" on the scale, so you can know exactly when to water it.
