How to choose indoor flowers?

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, so don't eat it, even if you stay up late and are hungry!

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, so as to avoid the wind blowing directly on the plants and causing their leaves to wither and scorch.

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;
