2 Plants 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. Plants are drought-tolerant, can grow and mature within half a year, and can survive if properly maintained 10 year? 15 years, and its branches and leaves can be changed at will, which 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. According to the test, a pot of 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.

The volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, Dianthus, lily of the valley, Lagerstroemia indica, etc. can kill germs and has obvious bactericidal effect.

Crape myrtle, jasmine, lemon and other plants can kill diphtheria, dysentery bacteria and other protobacteria within 5 minutes. 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 succulents such as cactus, such as mycobacterium tuberculosis, pneumococcus, staphylococcus and so on. The stomata on their fleshy stems are closed during the day and opened at night, which produces oxygen while absorbing carbon dioxide and increases the concentration of negative ions in indoor air.

Plants such as Hupilan, Huweilan, tequila, palm, kale, Sedum, Rooting and pineapple can also purify the air at night. Climbing plants such as Parthenocissus tricuspidata, grapes, morning glory, wisteria and roses can be planted around the house, so that they can climb along the wall or along the frame to form green trees, which can effectively reduce sunlight radiation and greatly reduce indoor temperature.

Experts think that these flowers and trees are not suitable for bedroom decoration.

Cordate telosma: A large number of olfactory particles will be emitted at night. If you smell it for too long, it will make people with high blood pressure and heart disease dizzy, depressed, uncomfortable and even worse.

Tulip: its flowers contain a toxic alkali, which will accelerate hair loss if exposed for too long;

Nerium oleander: It can secrete a milky white liquid, which will poison people for a long time, causing drowsiness, mental decline and other symptoms.

5 Correct placement of indoor plants

Plants can reduce the air pollution caused by indoor decoration, so many people buy them, but the arrangement of plants is not so simple. The arrangement of indoor plants can't be placed at will according to everyone's interests. Different plants have different ways and positions.

The frequency of going in and out of the main entrance of the living room is very high every day, so it is best for plants not to block the action, and upright flowers should not hinder the line of sight. The living room is most suitable for receiving guests and family members, so it is not suitable to put tall plants in the middle, and the number of flower varieties should not be too much. Just use a few plants to decorate it.

The living room and other rooms can be separated by plants, such as ivy and chlorophytum, to form green curtains, which look natural and elegant. Many people in the bedroom think that plants will absorb carbon dioxide and release oxygen, so putting more plants in the bedroom is good for the human body. This view is wrong.

The photosynthesis of plants is completely inhibited at night, and plants only breathe, that is, absorb oxygen and exhale carbon dioxide. Too many plants in the bedroom are bound to compete with people for oxygen, which will cause harm to the human body over time. Therefore, it is best to put a small amount of small plants in the bedroom, such as aloe, asparagus, or lilies and daffodils. Don't hang plants.

Its veins are tortoise-shell-shaped, with many rectangular holes and deep cracks, which are shaped like tortoise-shell lines, so it is called tortoise-back bamboo.

There are asparagus, chlorophytum, orchids, bamboo and so on. Indoor can be raised: cactus, cactus, cactus column, tiger orchid, agave and so on. Its function is opposite to that of other plants, that is, it absorbs carbon dioxide and releases oxygen, which can supplement indoor oxygen. Rhododendrons can absorb radioactive substances, and several pots of rhododendrons can be put after indoor decoration. Chlorophytum (put a pot of 8 square meters to keep the indoor air fresh) Aloe, agave and Huperzia all have the function of absorbing formaldehyde. Milan, cyclamen, violets and impatiens can absorb sulfur dioxide in the air, and the first three can also play a role in heat preservation. Jasmine, chrysanthemum, cockscomb and a bunch of safflower absorb oxides in the air and play a hypnotic role. Evergreen, rose (not suitable for long-term indoor display, which will make people feel chest tightness and discomfort), lily (which will cause excessive excitement of the central nervous system), palm and honeysuckle contain volatile oil, which has obvious sterilization and detoxification effects. Marigold can absorb chloride in the air, Chimonanthus praecox can absorb tribute in the air, and pomegranate can absorb lead. Special note: Do not put bauhinia, peach and bamboo incense, jade cloves, turmeric and cordate telosma indoors, which may endanger your health. Remember. For reference only.

Growing flowers and grass indoors can create a good microclimate. The air humidity in modern buildings covered with reinforced concrete precast slabs is far below the normal standard and almost the same as that in the desert. And a plant called sedge can turn "desert" into "oasis". Cyperus likes water, so potted Cyperus should be put in a deep sink. Many flowers and plants suitable for indoor planting have sterilization function. If you put some potted oranges, rosemary, peach trees and chlorophytum indoors, the bacteria and microorganisms in the air will be greatly reduced.

People will feel suffocated in a stuffy room. The reason is not the lack of indoor oxygen, but the lack of negative oxygen ions. When there is a TV or computer running indoors, negative oxygen ions will decrease rapidly. There are many plants that can be planted indoors that can produce negative oxygen ions-these plants are cypress, arborvitae and cedar.

If the indoor area is too small, you might as well change varieties and plant some low plants, such as cactus. At present, spruce and other low conifers are popular in the west, which can make the room full of refreshing tree fragrance.

Placing some anti-pollution flowers and plants in the living room can also play the role of an air purifier. For example, ivy can "eat" benzene, chlorophytum can "swallow" indoor carbon monoxide and formaldehyde, and bracts of Araceae can absorb benzene and trichloroethylene. 10 square meter room is good for air purification if there are anti-pollution plants.

Thank you for your suggestions. Because it is a second-hand house, the former owner planted many fruit trees, peaches, persimmons and pears.
