Which flowers can't be planted at home?
Here, potted flowers are divided into two categories: foliage plants and flowering plants. This division is easier for everyone to understand.
First, the problem of photosynthesis:
Photosynthetic plants absorb carbon dioxide to release oxygen during the day and absorb oxygen to release carbon dioxide at night. Some friends are concerned about whether photosynthesis will compete with others for indoor oxygen at night? This problem is now explained as follows:
In the presence of light, green plants absorb carbon dioxide and moisture in the air, carry out photosynthesis, and release oxygen equivalent to 70% of the total air they absorb. Plants can't do photosynthesis at night because they need to breathe, but they need to consume oxygen. Many people have doubts, will plants compete with people for indoor oxygen? It has been calculated that putting 30 tall plants indoors for one night consumes the same amount of oxygen as one person absorbs for one night. In fact, no house has so many plants, no house is airtight, and we won't feel lack of oxygen just because there is one more person at home. So in theory, there are plants competing with people for oxygen, which can be ignored.
Many flowers not only don't compete with people for oxygen at night, but also help people remove some harmful gases in the room.
Huwei orchid, chlorophytum, bamboo and ivy can absorb formaldehyde in the air;
The fluoride resistance and absorption capacity of kumquat, fig, pomegranate and begonia are 160 times that of common flowers and trees.
Oleander, safflower, gardenia and pomegranate can absorb indoor carbon dioxide;
Species such as cactus and tile pine have the opposite characteristics to photosynthesis and are good assistants to purify the air.
Second, indoor greening plants have alarm function:
When spots appear on the leaves of marigold and begonia, it shows that carbon dioxide pollution is serious;
When white or brown appears in the middle of the leaves of rhododendron and hibiscus, it shows that nitrogen dioxide pollution is serious;
Plum has the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehyde in the environment. Once sulfide appears in the environment, its leaves will appear mottled or even yellow and fall off.
People can use the characteristics of these potted flowers to detect the degree of air pollution. However, these functions of plants are limited. With the increase of the number of plants, their functions are also enhanced, and indoor plants cannot be completely satisfied. So always open the window to let the air convection.
Third, flowers suitable for indoor use.
Zi Yuan, Astragalus membranaceus, tobacco, Celosia cristata and other plants can attract a large number of radioactive nuclides such as uranium;
Aloe, chlorophytum, and Huwei orchid can remove formaldehyde (especially chlorophytum, put a pot in the room, and its leaves will "eat" harmful gases such as carbon monoxide in the indoor air within 24 hours, even exceeding the air filter);
Ivy, rose, rose, aloe and evergreen can effectively remove trichloroethylene, sulfur specific hydrogen, benzene, phenol, hydrogen fluoride and ether indoors;
Pigeonpea, Phyllostachys pubescens and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases;
Asparagus can remove heavy metal particles;
Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air;
Narcissus, mirabilis jalapa, chrysanthemum and Celosia cristata can transform nitrogen oxides into protein, thus removing toxicity.
In addition:
Chlorophytum can also effectively absorb carbon dioxide;
Some fleshy flowers of cactus rarely emit carbon dioxide at night;
Wisteria (or crape myrtle? My memory is not deep. I'll check it again. ) has strong resistance to sulfur dioxide, hydrogen chloride, chlorine gas and hydrogen fluoride, and also has certain resistance to chromium.
Camellia can resist harmful substances such as sulfur dioxide;
Some leafy and water-loving plants, such as radish, can keep the indoor air humidity in an excellent state;
Heart-leaf evergreen velvet antler has strong shade tolerance, high air humidity and vigorous growth. Fertilizing once a month can promote the color of leaves to become beautiful.
Narcissus is a high-quality flower in winter, but it contains a small amount of colchicine. Don't eat it. Even if you are hungry after staying up late at home, you must never eat!
Fourth, indoor flowers should not be selected.
Although Chinese rose can absorb many harmful gases, its rich fragrance will make people feel depressed and uncomfortable, hold their breath and even have difficulty breathing;
Rhododendron, tulip, lily and poinsettia can also absorb volatile chemicals, but Rhododendron flavum contains a toxin, which can lead to poisoning if eaten lightly, and shock in severe cases.
Tulip flowers contain a toxic alkali, which will accelerate hair loss when exposed for a long time;
The fragrance of lily, if smelled for a long time, will make people's center excessively excited and cause insomnia;
Pollen of bauhinia flower, if exposed for a long time, will induce asthma or aggravate cough;
Mimosin in mimosa is a very toxic organic substance, and excessive contact with human body will cause hair loss;
Nose-stimulating particles emitted by cordate telosma at night can make patients with hypertension and heart disease feel dizzy, depressed and even worse. However, cordate telosma is an ornamental fragrant flower, and its rich aroma can repel mosquitoes, which is generally used in courtyards and balconies.
Five, air conditioning indoor flower arrangement and management
1. What flowers are suitable for air-conditioned rooms?
In air-conditioned rooms, flowers with high leathery leaves or thick cuticles should be selected, which have strong resistance to dry environment, such as peach-leaf coral, rubber tree, octagonal golden plate, Liriodendron chinense, evergreen, Mahonia, Dendrocalamus latiflorus, spring feather, Phoebe bournei, pineapple, mallow, mallow, brown bamboo and red mallow. It is not suitable to choose colored grass, lily, jasmine, peach, Hosta, Hulk, purse peony, triangle maple, taro and so on.
2. Flower management in air-conditioned rooms
The flowers in the air-conditioned room should pay attention to the combination of watering and spraying water, and spray water on the leaves appropriately. It is best to fertilize the flowers in the air-conditioned room before entering the room. If potted flowers are yellow or grow badly due to lack of fertilizer, a small amount of compound fertilizer can be applied, and indoor pollution cannot be caused by fertilization. In order to maintain the beautiful crown shape of potted flowers, attention should be paid to core removal and pruning, and some new shoots should be trimmed to promote the germination of lower lateral buds. If there are insects and diseased branches and leaves, they should be removed in time, and pesticides should not be used indoors. When placing potted flowers, pay attention to stay away from the air outlet of the air conditioner to avoid the wind blowing directly on the plants, causing the leaves to wither and burn.
As for the flowers in the office building, professional potted flowers and flower renters should provide maintenance services. Because of the complexity of environmental factors and human factors in the office building, if not treated in time, the plant diseases will be very serious. Therefore, it is necessary to go to a professional greenhouse for maintenance, pruning and transplanting (the specific pruning and transplanting methods are quite complicated, and snake snakes still advise you not to do it easily. If the operation is wrong, the plant is likely to die soon) and other restoration work.
VI. Selection and Design of Indoor Flowers
1, mainly foliage plants with strong shade tolerance;
2. Some large potted flowers, such as rubber trees, tortoise shells and cycads, can be placed in a big room, which makes people feel beautiful and generous;
3. If the walls and furniture are dark, light potted flowers should be placed in light flowerpots. In addition, suitable purple sand pots, flower baskets and bamboo woven pots can be placed on pottery pots.
4. The growth posture and placement position of potted flowers should be appropriate. For example, if plants grow vertically or are very high, they should be placed in a lower place. For some potted flowers with hanging branches and leaves or expansibility, they should be placed in a higher place, which will have a three-dimensional effect;
Before moving potted flowers from outdoor to indoor, pay attention to whether there are pests in the soil. If there are pests, they can be lured out of the pot with sweet bait outdoors to eliminate them;
6. Fertilizing with some good quality fertilizers can promote the growth of flowers and prevent soil from hardening;
7. In order to effectively remove indoor pollutants, some different kinds of flowers and trees with special functions can be placed, and the following types are more suitable (see also titles III and IV above):
Chlorophytum, Gerbera jamesonii and non-flowering ornamental birch mainly absorb formaldehyde, benzene and nicotine;
Red zygomatic flower absorbs xylene, toluene and ammonia; Dracaena cochinchinensis, daisy and evergreen can remove trichloroethylene;
Ear fern, ivy, cycad and chrysanthemum can decompose harmful substances such as formaldehyde, xylene and toluene;
These flowers are especially important for newly decorated new houses.
Seven, indoor flower placement
It should be determined according to the room size, lighting conditions and personal hobbies.
1. If the room is large and sunny, kumquat, camellia, begonia, etc. Those with drooping branches and leaves can be placed directly on the ground or above the bookshelf;
2. If the room is not big, there should be fewer indoor flowers, and 2-3 pots are appropriate. Choose small and exquisite plants, such as 1-2 pots of daffodils and cacti in the study, and decorate the bedroom with Milan and jasmine.
Theoretically speaking, the arrangement of flowers can be divided into three types: ornament type, natural type and hanging type.
1. Ornamental type is to place potted flowers on the windowsill, desk and coffee table, which is better with elegant flowerpots and vases.
2. The natural style is to organically combine the outdoor natural landscape with the indoor decoration, such as placing vines such as honeysuckle and grapes in front of the balcony or window sill, and integrating with the outdoor natural landscape.
3. Hanging is to hang elegant hanging potted plants and flowers in the study, corridor and other places.
Eight, the maintenance of flowers
Conservation involves the biological characteristics of different kinds of plants, and there are many methods. So I only mention some of them here, so I won't list them one by one:
1. frequently asked questions
Most families can't reach the humidity in the greenhouse, and most native tropical plants like the humid environment. In the greenhouse, flowers can receive sunlight all day through the sunshade net, so that they do not receive direct sunlight, while in the family, there is often insufficient light or sunlight. Many flowers like semi-cloudy environment, but the sunshine is too weak in winter, so flowers can fully accept the sunshine. The suitable growth temperature of most flowers is between 65438 05℃ and 20℃. If the temperature is too high, the flowers will bloom quickly, which is easy to cause problems.
The greenhouse needs regular fertilization and proper watering, and it needs compound fertilizer suitable for each growth stage. At home, they are often malnourished because of lack of gardening knowledge, or they don't fertilize, or they burn flowers because of heavy fertilization at one time. In particular, it should be noted that chemical fertilizer or a small amount of compound fertilizer cannot be applied during flowering, and "hypertrophy" is not good for flowering.
Flowers like neutral or acidic soil. If the tap water is alkaline, long-term watering will make the soil alkaline and affect the quality of flowers. If the soil is thick and airtight, it will also affect the respiration of roots and even rot. When the water is wet, it is basically dry. The evaporation in winter is small. Don't water it often. Too much water tends to rot the roots. Be sure to touch the basin soil with your hands before watering, so that you can master the degree of dryness and wetness of the soil and avoid blind watering.
Most flowers in the Spring Festival like the environment with high air humidity. Water should be sprayed around the flowers to increase the air humidity. Try to keep flowers in sunny and well-ventilated places to avoid pests and diseases. The temperature of the living room should not be lower than 5℃ or higher than 25℃. High moisture, low air humidity and high temperature are often the main factors leading to problems in flowers.
2. Maintenance methods
Bulb flowers: daffodils, daffodils, tulips and hyacinthus orientalis are all seasonal flowers. The flowering period is very short, usually only 1 to 2 weeks. They can be placed indoors in sunny and low temperature places. If the temperature is too high, the flowers will bloom quickly and the flowering period will be shortened.
Orchids: Clivia, Cymbidium hybridum, Phalaenopsis, Cartland, Dendrobium, etc. It grows under tropical trees in nature, likes damp and cool, avoids direct sunlight, and grows well in bright semi-shade. Therefore, it is necessary to spray more water at home to increase the air humidity. In winter, you can accept soft sunshine, make it carry out photosynthesis and increase nutrition. Orchids are susceptible to snails and scale insects and can be brushed off with a toothbrush. Take the common Clivia as an example, it is native to the subtropical South African forest, where the seasons are like spring, the average minimum temperature is not lower than 10℃, and the maximum temperature is not higher than 22℃. Clivia likes to live in a warm and humid natural environment with moderate humidity, so families should also create a similar environment. Clivia likes soft light to avoid exposure to the scorching sun. Clivia is a fleshy root with certain drought resistance. Too much watering will lead to root rot. The water content of Clivia basin soil should be kneaded by hand and loosened by light pressing.
Arundo donax and ferns: Arundo donax, such as peacock arrowroot and purple-backed arrowroot, and ferns, such as Boston fern, like semi-cloudy, warm, high-humidity, well-drained environment, like strong light and are not resistant to direct sunlight.
Other flowers
Calla lily: It's so bright, water and fertilizer. It likes wet soil and high air humidity.
Flamingo: Also known as Anthurium andraeanum, it likes humid, warm and well-drained environment. Scale insects are its common pests, so we should pay attention to prevention and control and brush them with a brush.
Guayeju: like sunshine, wet and fat, but reduce fertilization at flowering stage, and water it properly to prevent it from being too dry or wet. When the temperature is low, water should be controlled, moistened slightly, and ventilated, otherwise, Guayeju is prone to powdery mildew or be harmed by aphids and red spiders.
Dayantong: I like warm and humid, so I am fat and avoid direct sunlight. Cyclamen likes sunny, cool and humid climate, 10℃ to 20℃ is the suitable growth temperature, and it is afraid of high temperature.
Belgian Rhododendron: Sexual preference is cold, humid and acidic humus soil.
Crab claw orchid: I like warm, humid and semi-cloudy environment. The optimum growth temperature is 15℃ to 20℃, and when it is lower than 5℃, it will enter a dormant state.
Calceolaria: I like a warm, cool, humid and well-ventilated environment. I am not cold-resistant and avoid humidity.
Rieger Begonia: I like warm, humid and semi-cloudy environment.
Poinsettia: loose and fertile soil, like plenty of sunshine, need good drainage and ventilation, and have strict requirements on water. Too much soil moisture often causes root diseases, which in turn leads to defoliation; If the soil moisture is insufficient, plants will grow poorly and shed leaves.
Kumquat: It likes warm and humid sandy soil with abundant sunshine, and should be fertile, well drained and well ventilated. Not cold-tolerant, avoid drought.
Watch pineapple: I like high temperature, humidity and semi-cloudy environment. Sandy soil containing humus should be selected as potting soil, and the wintering temperature should be above 10℃.
