What plants are put at home to help physical and mental health?

Three kinds of plants are most suitable for indoor display. With the improvement of living standards, it has become a fashion for people to use green plants for indoor greening and decoration. According to expert analysis, the following three kinds of plants are most suitable for living room. ■ Plants that can absorb toxic chemicals, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus japonicus, are natural scavengers, 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, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, Milan, daisy, Chimonanthus praecox, calendula, etc. It can effectively remove harmful substances such as carbon dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide. Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans are natural dust collectors, and their cilia can intercept and absorb suspended particles and smoke in the air. ■ 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, and its genetic structure has been changed. It was only 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. 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. ■ Volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley, Lagerstroemia indica, etc. can kill germs and has a significant 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 mycobacterium tuberculosis, pneumococcus and staphylococcus. Cactus and other succulents native to tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, increasing the concentration of negative oxygen ions in indoor air. Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air. 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. Lilac, jasmine, rose, violet, mint and other plants can make people relax, feel happy, help sleep and improve work efficiency. Keeping some lush plants in your room is not only pleasing to the eye, but also a "natural oxygen bar" for your room. But you know what? The placement of plants is also related to the location of the room. Yan Liu, a professor of botany at the School of Landscape Architecture of Beijing Forestry University, said that it is advisable to divide the living room into seven locations and put the most suitable plants. Entrance and window: suitable for placing hydroponic plants or tall plants, such as hydroponic bamboo, evergreen trees, rich trees, or tall cycads and banyan trees. Because these places are generally windy and the air mobility is relatively large, raising some tall plants or aquatic plants is conducive to maintaining indoor humidity and temperature balance. Living room: suitable for planting ivy, figs, pitcher plants and common aloe. The living room is a place where people come and go. These plants can not only deal with bacteria and insects brought back from outdoors, but also absorb dust that even a vacuum cleaner can't absorb. Dressing table and desk: Perrin's leaves will change cyclically with the change of temperature, green, white, pink and pink, and finally turn back to green, and put them next to the master's desk to support temperament. In addition, Metasequoia glyptostroboides, bluegrass and other ornamental plants are also suitable to be placed here. Joke: It is best to hang some vines, such as green radish, green elves, ivy and so on. These plants are easy to shape, and the passages are generally very ventilated, which is their best growing environment. Toilet: The leaves of Huweilan can absorb the water vapor in the air by themselves, which is an ideal choice for toilets and bathrooms. Ivy can purify the air and kill bacteria. It is a shade-tolerant plant. You can also put it in the bathroom. Ferns and peppers like humidity, so they may as well be placed next to the bathtub. Bedroom: suitable for placing some flowers and plants that can absorb carbon dioxide and other waste gases, such as potted oranges, rosemary, chlorophytum and zebra leaves. Their smell is not strong enough to make people dizzy. In the bedroom, you can also raise some plants with big leaves and love water, such as green radish, to keep the air humidity in the best condition. Kitchen: Chlorophytum and green radish have strong air purification and mosquito repellent effects, which are the best choice for the kitchen and can also be placed on the refrigerator. In addition, different floors are also suitable for planting different plants. Low-level residents, it is best to raise shade-tolerant plants such as orchids, azaleas, asparagus, chlorophytum and camellia. Households with higher floors are more suitable for raising some plants that like sunshine, such as bougainvillea, osmanthus fragrans, Michelia, gardenia, jasmine, Milan, cactus, cactus, dragon boat flower, colorful hibiscus and so on. For these plants, it is best to choose the southeast direction for placing flowerpots, because the time of direct sunlight here is the most suitable. The more plants at home, the better. Some plants can purify the air and prevent diseases; Some plants may bring a lot of discomfort to human body. What plants should be placed at home must be carefully selected. Names of plants suitable for home use (1): aloe, chlorophytum and Phyllostachys pubescens. They are natural scavengers, which can remove harmful substances in the air, especially in dealing with formaldehyde. Studies have shown that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and aloe can absorb 90% of formaldehyde contained in 1 m3 air. (2) Name: Household appliances and plastic products such as ivy, cycad, chrysanthemum, kumquat, pomegranate, mirabilis jalapa, rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox and marigold emit harmful gases such as sulfur dioxide, fluorine, chlorine, ether, ethylene, mercury vapor, lead vapor, carbon monoxide and nitrogen peroxide. Using these plants, (3) the volatile oil produced by the names: rose, osmanthus, violet, jasmine, rose, carnation, lily of the valley and Lagerstroemia indica has obvious bactericidal effect. It has obvious inhibitory effect on the growth and reproduction of tuberculosis, pneumonia and staphylococcus.
