The fragrance emitted by plants such as rose, gypsophila, lily of the valley, violet, rose and osmanthus has a significant inhibitory effect on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus and staphylococcus. 4, natural oxygen generator – cactus and other succulent plants native to tropical arid regions, the stomata on their fleshy stems close during the day and open at night, absorbing carbon dioxide while creating oxygen, so that the concentration of negative ions in the indoor air increases. Tiger lilies, tiger orchids, agave and brown hairy palm, Galanthus, Sedum, deciduous roots, cultivated bromeliads and other plants can also purify the air at night. 5, spiritual booster – lilac, jasmine, rose, violet, mint and other plants can make people relaxed, happy spirit, conducive to sleep, but also to improve efficiency. 6, effective disease prevention – roses, Dianthus, lily of the valley, violets, roses, osmanthus and other plants emit fragrance on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus, staphylococcus has a significant inhibitory effect. 7, cooling race air conditioning – planted around the home climbers, grapes, petunias, wisteria, roses and other climbing plants, so that they climb along the wall or along the shelf, forming a green pergola, can effectively reduce sunlight radiation, greatly reducing indoor temperatures. The disadvantages of keeping flowers indoors: 1, the night to incense – at night after the cessation of photosynthesis will emit a lot of exhaust gas, this exhaust gas smells very fragrant, but is not good for human health. If you put it indoors for a long time, it will cause dizziness, cough, and even asthma, insomnia. Therefore, during the day to put the night incense indoors, in the evening should be moved to the outdoors. 2, tulip – flowers contain toxic alkali, people and animals in this bush for 2 hours – 3 hours, will be dizzy, symptoms of poisoning, serious cases will also make hair loss, should not be planted at home. 3, zinnias – it emits pollen human contact for too long, will induce asthma or make cough symptoms worse. 4, pine and cypress – such flowers and trees emitted by the aromatic smell of the human gastrointestinal stimulation, such as the smell of too long, not only affects the appetite, and will make pregnant women feel distracted, nausea and vomiting, dizziness. 5, moonflower – the strong fragrance emitted, will make individuals suddenly feel chest discomfort after smelling, breathing difficulties.

The family should not be greedy for flowers: family flowers should be based on the size of the room to choose the size of the plant, the number of moderate, beautiful appearance, harmless to the family species. Some flowers contain toxins such as Dujuan flowers, zinnias, etc., once accidentally eaten can cause poisoning. When daffodils and drip flowers are stained on the skin, they can cause redness, swelling, pain and other allergic symptoms. Therefore, special attention should be paid to the management of these plants, and they should be placed out of the reach of children so that they do not play with them or eat them by mistake. Plants with sharp thorns can pose a threat to human safety and should be placed away from family activities. Indoor flowering is not the better: Generally, for a room of about 15 square meters, only 2 medium-sized and large plants should be placed, while small plants can be placed in 3 to 4 pots. In addition, to create a green oxygen bar, in addition to the green plant strain, flower color, but also consider the way they absorb carbon dioxide. Some plants belong to the night oxygen consumption and release of carbon dioxide, it is best to move to the outside of the house at night, to avoid its competition with people for oxygen, affecting health. Sick room, bedroom night should not keep flowers: many flowers have the role of purifying the air and promoting health, but some flowers if kept at home, but will become a source of disease, or lead to the recurrence of old diseases, old diseases aggravated by “killers”, so it is recommended that before raising flowers must understand the nature of flowers, to prevent flowers a raised, the body out of order. Patients do not keep potted flowers indoors – because the soil in the pots will produce fungal spores, when they spread into the air, easy to invade the human skin, respiratory tract, external ear canal, meninges and brain and other parts of the brain, will cause infection, which is very harmful to patients who originally suffered from the disease. Bedroom night should not put flowers – because most of the flowers are daytime photosynthesis through the absorption of carbon dioxide, the release of oxygen, but at night, it is just the opposite. Therefore, it is best not to put flowers in the bedroom, flowers placed during the day, at night to move out of the outdoors, at least not in the bedroom, so as not to affect the health of the family.
