Flowers compete for oxygen.
Aunt Jiang has been raising flowers for many years. When she lived on the first floor, she put them in the yard. Aunt Jiang has moved all the flowers into her home since she moved into her new home last year. Every morning when the sun comes out, Aunt Jiang's first thing is to move the flowers to the balcony and let them fully enjoy the sunshine. At night, in order to prevent the flowers from freezing, Aunt Jiang always moves them back indoors and puts them where they can be seen at a glance.
However, Aunt Jiang's family has always felt that waking up every day is not only weak, but also accompanied by chest tightness. Later, the doctor diagnosed that it was because of too much carbon dioxide and lack of oxygen indoors, and suggested that she transfer all the extra flowers in the bedroom to other places.
Flowers also need to breathe.
The doctor told Aunt Jiang that under normal circumstances, green plants will carry out photosynthesis, absorb carbon dioxide and release oxygen during metabolism. However, when the light is insufficient, plants mainly breathe, not photosynthesis. At this time, plants, like people, inhale oxygen and expel carbon dioxide. Especially at night, because of insufficient light, the photosynthesis of plants is completely inhibited, and the respiration is very strong. If there are too many flowers and plants indoors, the indoor carbon dioxide concentration will increase, which is not good for health.
When I wake up every day and see these green things, I feel my eyes light up. Aunt Jiang told reporters that I didn't expect these flowers and plants to have a temper.
Flowers are not everything.
In a flower and bird market in the northeast corner of the city, the reporter saw dozens of flowers and plants marked with environmental protection signs, which can either take medicine, purify the air, sterilize and remove dust, and even prevent radiation. A vendor selling poisonous weeds said that sometimes hundreds of pots are sold a day, and many people buy dozens of pots at a time, all of which are newly renovated houses.
It is understood that not all flowers and plants have the function of absorbing harmful compounds, nor can one flower and plant absorb a variety of compounds, and the absorption of harmful compounds by flowers and plants is trace, and high concentration of harmful gases may cause plants to die.
The Indoor Environment Testing Center of China Interior Decoration Association once determined that 1 1 species of flowers would be harmful to human health in some cases. For example, dripping Guanyin, the juice secreted by the stem will cause itching after contact with the human body, and contact with the wound will also cause poisoning.
There are also universities that require indoor flowers to be placed in feng shui.
First, flowers can absorb toxic chemicals.
Aloe, chlorophytum, Eupatorium odoratum and Eupatorium odoratum are natural cleaners, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good hand at absorbing formaldehyde, which can absorb 90% formaldehyde contained in 1 m3 air.
Ivy, cycad, kumquat, pomegranate, Scutellaria barbata, rose, camellia, Milan, daisy, Chimonanthus praecox, marigold, etc. can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.
Orchids, osmanthus, wintersweet, cauliflower taro, osmanthus, etc. They are natural dust collectors, and their cilia can intercept and absorb floating particles and smoke in the air.
Second, flowers that can repel mosquitoes.
As the weather gets warmer, plants that can repel mosquitoes have become the focus of attention. Mosquito net vanilla is such a plant. It is an aromatic geraniaceae plant, its genetic structure has been changed, and it has only been introduced from Australia in recent years. The plant is drought-tolerant, can grow and mature within half a year, can survive for 10 ~ 15 years after proper maintenance, and the shape of branches and leaves can be changed at will, so it has high ornamental value.
Mosquito net vanilla gives off a fresh and elegant lemon fragrance, which has a good mosquito repellent effect indoors, but it has no toxic side effects on human body. The higher the temperature, the more fragrance it emits, and the better the mosquito repellent effect. After testing, the mosquito net vanilla with a crown width of more than 30 cm can drive away mosquitoes in a room with an area of more than 10 square meter. In addition, a plant called pyrethrum contains pyrethrins, which can also effectively repel mosquitoes.
Three-dimensional green room flowers
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. Traditional plants such as ivy, canna and evergreen also have the function of regulating indoor air.
It should be noted that try not to plant some fragrant flowering plants indoors. Like oleander or something.
Indoor flowers and plants fengshui daquan
People have always liked flowers and plants. With the maturity of technology, flowers that should have grown outdoors have also entered the houses where people live. More and more people choose to decorate their houses with flowers to adjust the feng shui at home. Let's take a look at the indoor flower feng shui encyclopedia!
Indocalamus, also known as Yunpinsong and Yunzhu, is an evergreen vine foliage plant. Asparagus in Liliaceae. Warm and humid, temperature 15~25℃. Because its shape is suitable for viewing, its roots can be used as medicine, and it can absorb harmful gases and secrete bactericidal gases at night, which can reduce the occurrence of various infectious diseases such as colds and typhoid fever. Therefore, everyone likes asparagus more when they grow flowers indoors. Decorate it in the office, because it has elegant and unique meaning.
Green radish, also known as golden vine, is an evergreen herb and likes hot and humid environment. Radish leaves are big, which has a good effect on improving indoor environment after decoration. The suitable temperature for the growth of green radish is 20℃~30℃, so it is generally arranged in the southeast of the room. But from the perspective of feng shui, the southeast is auspicious, so the office often decorates the green radish as a feng shui plant.
Drip Guanyin, also known as drip lotus, Araceae, Alocasia, is an indoor flower. Likes to be moist, and the growth will stop when the temperature is lower than 18℃. However, due to its large leaves, strong transpiration and strong moisture emitted into the air, it is easy to remove dust from the air. From the perspective of geomantic omen, taking the meaning of dripping water is a water-increasing genus, which is one of the common plants in office flower placement geomantic omen.
The indoor flower god of wealth tree, also known as melon chestnut, kapok family, evergreen small tree. I like high temperature and high humidity climate. Wealth trees can absorb harmful gases such as formaldehyde and purify the air. The key point of breeding is to pay attention to temperature. The lowest temperature in winter is 16- 18℃, which is generally suitable for indoor breeding. Wealth tree is named after its palm-shaped leaves, which has a good meaning. Feng shui, the green plants in the office, is always indispensable.
Selection of Plants in Family Greening
On the Selection of Tree Species
Planting trees in the yard is dispensable. According to geomantic omen, plants can be divided into two categories: bad luck and bad luck. There are two criteria for dividing the perpetrators: one is based on whether there is poisonous gas or venom, which has certain scientific basis. For example, some scholars believe that cordate telosma will emit a large number of particles that strongly stimulate the sense of smell at night, which has adverse effects on patients with heart disease and hypertension. The flowers of oleander are poisonous, and the fragrance of flowers makes people sleepy and reduces human function. Tulip flowers have soil alkali, which is easy to fall off when exposed to hair too much. This is a fierce tree and should not be planted in the yard. The other is the shape of a tree, such as a strange tree, a miserable tree name, a hunchback tree, a lucky cow, and a humble abode. All ugly, dignified and abnormally developed trees are fierce. I'm afraid this is a psychological effect or a traditional humanistic aesthetic concept at work.
As for auspicious tree, it is determined according to plant characteristics, meanings and even homophones, and people tend to hold this view in real life. For example, Feng Shui scholars believe that 65,438+03 plants such as palm, citrus, bamboo, Toona sinensis, Sophora japonica, Ganoderma lucidum, plum, Ficus microcarpa, jujube, pomegranate, grape and begonia are auspicious plants, while peach, willow, wormwood, ginkgo and cypress are auspicious plants.
About planting orientation
Ancient geomantic classics have some conclusions about this: planting peach poplars in the east, plum dates in the south, elms in the west, oranges and plums in the north, weeping willows in front of the door, unlucky, locust trees in the middle door, wealth for the third time, elms behind the house, exorcising ghosts, planting double dates in front of the door, making money with bamboo forests on all sides, mulberry trees in the four corners of the house, and so on. From the above conclusions, combined with modern scientific knowledge, we think that some conclusions contain natural scientific knowledge, while others are a psychological need to avoid misfortune. For example, peach trees are planted in the east because the sunrise is the first in the east, willow trees germinate earlier, and peach blossoms are one of the earliest flowering plants in spring, so it is more reasonable to plant them in the east, elm trees are wet plants, and it is more appropriate to plant them in the west when the sun is not afraid. As for the saying that locust trees attract wealth and elm trees exorcise ghosts, there are probably many superstitious elements. Willow should not be planted in front of the main gate, which may refer to willow's leisure and hate work, which is psychologically unacceptable.
About the number of trees planted
Feng Shui advocates reasonable close planting. It thinks: when the surroundings are large and narrow, don't plant many kinds of trees, otherwise it will help to shade them; Only the sparse left and right behind are densely planted to block their emptiness. We agree with this view, but some of the following statements are too superstitious, so we can abandon them: the single tree is the door, the widowed mother is an orphan, the door is facing the forest, the sudden illness is fierce, there are two trees in front of the door, the livestock are injured, the left tree has no right, the lucky tree is less fierce, the left tree is three or five, the husband and wife fight, the two trees are sandwiched between houses, the surnames are not harmonious, and the left tree is heavy.
About the size of a tree.
It is more suitable to plant big trees in the yard, and different feng shui schools have different requirements. In geomantic omen, the formal school thinks it is appropriate to plant rows of big trees around the house to stop the suffocation. In order to meet the needs of the situation, when building a house on the plain or in a relatively flat place around it, trees and flowers can be used to create a pattern of four gods: Zuo Qinglong, Zuo Baihu, Qian Su Zaku and Hou Xuanwu, that is, planting big trees in the back of the house, medium trees on the left and right sides, and low shrubs or grass in front. This way is understandable from the aesthetic point of view, which meets the psychological needs of people looking for a treasure house of geomantic omen.
In geomantic theory, it is believed that trees should be planted in high places and low plants should be planted in low places. For example, the theory of "Year of Eight Houses" holds that trees should be planted only when there are natural medicines in the house, and there is longevity and vitality. Dwarf trees or grass can be planted in other directions. According to the laws of metaphysics, only the true god can plant trees, but the direction of the zero god is not suitable. This method may have no scientific basis or aesthetic feeling.
The flower arrangement in the living room is exquisite.
If your room is large, sunny during the day and you like to sleep with the doors and windows open, you can consider raising some plants properly.
Putting some flowers indoors properly can not only add a warm atmosphere, but also be beneficial to physical and mental health. However, many people mistakenly think that the more flowers, the better, blindly placed, so that the room is beautifully decorated, but did not expect that beautiful flowers will also cause harm to human health.
If your bedroom is small and poorly ventilated, you'd better give up the idea of sleeping with plants. Like people, plants breathe, inhale oxygen and exhale carbon dioxide all the time. On sunny days, they can still carry out photosynthesis, produce oxygen and make up for consumption; At night, they can only compete with you for oxygen. If the leaf area of a small pot of chlorophytum is less than 0. 1 m2, the oxygen consumption rate is less than that of healthy adults at rest. However, the closed bedroom at night may be a little oxygen-deficient, and there are too many plants, especially broadleaf plants with high oxygen consumption. Watch out for nightmares. Of course, if your room is large, sunny during the day and you like to sleep with the doors and windows open, you can consider raising some plants properly.
Don't put plants with special smells in the bedroom.
In the bedroom, plants with strong flowers or special smells are not suitable for long-term display. Plants produce volatile gases, either to attract insects to pollinate, or to drive away insects, or to send signals to inhibit the growth of other plants and microorganisms. These gases are generally not aimed at humans. Therefore, these gases rarely cause serious harm to human body. But there are still some special cases, such as Datura stramonium, cannabis, Datura stramonium and so on. Its volatile gas can cause neurotoxicity; Poisonous wheat and ragweed can cause rhinitis and shock; Volatile terpenoids contained in Euphorbiaceae and Daphne family plants can cause skin and mucous membrane irritation and poisoning. Fortunately, most of these plants are not common garden plants, so you don't usually keep them at home.
In addition, there are some similar experiences generally recorded in gardening literature, such as some flowers such as lilac, cordate telosma, geranium and five-color plum. The smell they give off is easy to cause too strong stimulation to people's sense of smell in a closed space, which may cause dizziness, chest tightness and fidgeting.
Cancer-promoting plants exaggerate.
There is a blacklist of carcinogenic plants, including Datura stramonium, Rosa davurica, oleander and 52 other plants. Some people think that some common flowers (mostly toxic plants such as Daphne odora and Euphorbiaceae) can induce and promote cancer through volatile gases. However, this view has not been reported in any official magazine. Previous studies have proved that only the Rosa davurica extract mentioned in the blacklist is toxic, and no obvious carcinogenic or toxic substances are found in the volatile gas it produces. Therefore, whether this blacklist of cancer-promoting plants is true or not needs further study.
Dr Shi Lei from Beijing Botanical Garden, Institute of Botany, Chinese Academy of Sciences pointed out that there are not many ornamental plants on the list, most of which grow in the south and are mainly used as medicinal materials. Because most of them have no ornamental value, they will not be introduced to the northern region. On the blacklist, as ornamental plants, they are mainly kept at home or sold in the market: mutual leaves, roses (also known as begonia), red corals (also known as hard-core lilacs), kirin crowns (also known as jade kirin) and impatiens.
How to choose plants for the bedroom
There is no need to be afraid to get along because of poisonous flowers and plants. Common poisonous cultivated plants, whether they are oleander, digitalis, evergreen rich in cardiac glycosides, or famous Euphorbiaceae poisons (such as poinsettia), are deeply hidden in the body and generally will not be released in the form of gas. As long as you are not a sleepwalker, it is safe to plant a blood-soaked tree in your bedroom to seal your throat without eating the leaves on your pillow when you sleep.
There are other considerations in the choice of bedroom plants. For example, in order to make the mood quiet, it is not advisable to place plants with too bright colors. For another example, from the perspective of safety, try not to choose plants with acupuncture effect such as cactus. Also, if you keep chlorophytum, don't hang it on the bedside, or it will fall and hit people. Pay special attention to the allergic history of family members when arranging plants in the bedroom. If people are allergic to pollen, don't put fresh cut flowers, especially lily, orange stalk, narcissus and other flowers with exposed pollen. We can put some foliage plants, which will be safer.
