Formaldehyde is a common pollutant in indoor air and is mainly found in carpets, insulation materials, plywood and other items. As we know, formaldehyde has been identified as a carcinogen and teratogen by the World Health Organization. Formaldehyde ranks second on my country's priority control list of toxic chemicals. Therefore, for the health of your family, it is very important to absorb formaldehyde in indoor air. At this time, you might as well raise some potted plants at home, which in addition to absorbing formaldehyde, can also green the home environment. So, which potted plants are called "formaldehyde busters"? Let’s introduce some potted plants with good formaldehyde absorption effect to you, let’s learn about them together.

1. Chlorophytum

Chlorophytum can perform photosynthesis under weak light, absorb toxic and harmful gases in the air, and absorb formaldehyde, styrene, carbon monoxide, and carbon dioxide in the air. and other carcinogens. Generally, keeping 1-2 pots of spider plants in a room can absorb all the toxic gases in the air. Spider plants can also decompose benzene and absorb relatively stable harmful substances such as nicotine in cigarette smoke. Therefore, spider plants are also known as "air guardians". Although Chlorophytum is a semi-shade flower, it needs at least four hours of astigmatism every day, otherwise the chlorophyll will decrease and the leaves will turn yellow. Chlorophytum can also be cultured with hydroponics. To do hydroponics, you can first pour the potted Chlorophytum out of the pot, wash the soil with water, cut off the old leaves and roots, place it in a hydroponic vessel, and then pour in clean water. Can. Be careful not to use too much water, just enough to reach the roots and stems. For vigorous growth, add a few drops of nutrient solution to the water. The utensils can be wide-mouth glass bottles, glasses and other containers. The water in the container can be changed every few days, or just add some water.

2. Sansevieria orchid

Sansevieria orchid plays a good role in purifying the air. Studies have shown that Sansevieria can absorb some harmful indoor gases, and can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, and nitrogen peroxide. It has a strong ability to absorb formaldehyde. Tiger Piranchia does not have strict soil requirements. The potting soil can be made of leaf mold soil and 1/3 river sand. Usually put it in a sunny place with good ventilation for maintenance. Watering should be done both dry and wet, especially in the seedling stage. It is not advisable to water too much, otherwise it will easily cause the roots to rot or even die. In summer, it needs to be moved to a northern balcony or indoor place with bright scattered light, and spray water on the leaves 1-2 times a day to keep the air moist and keep the leaves dark green. Apply a thin liquid fertilizer combining nitrogen and phosphorus every 2-3 weeks during the peak growing season. If only nitrogen fertilizer is applied for a long time, the spots on the leaves will become dull. In winter, place it indoors in a sunny place and control watering, but you still need to spray warm water on the leaves every 5-7 days to keep the leaves clean and prevent them from being contaminated with dust. The indoor temperature should not be lower than 12. Every 1-2 years, combine the ramets and repot them in spring. Since the leaves of tiger orchid grow upright and upward, it is advisable to use a tube pot to show the compactness and beauty of the plant.

3. Ivy

Ivy can effectively remove formaldehyde and benzene, and can effectively decompose two harmful substances, namely formaldehyde and benzene that exist in carpets, insulation materials, and plywood. Xylene, which is harmful to kidneys, is hidden in wallpaper. Ivy is a shade vine that can also grow in a full-sun environment. It grows well in warm and humid climate conditions and is not cold-tolerant. It has no strict requirements on soil, prefers moist, loose and fertile soil, and is not intolerant to salt and alkali. During the growing season, water should be dry and wet, and the pot soil should not be too wet, otherwise it will easily cause root rot and leaf fall. In winter, when the room temperature is low, watering must be controlled especially to keep the pot soil slightly moist. The climate in the north is dry in winter. It is best to spray the Duchuan with water close to room temperature once a week to maintain the air humidity. The plants will appear vibrant and the leaves will be green and shiny. Although the cultivation and management of ivy is simple and extensive, it also needs to be cultivated in an environment with good air circulation and moist soil. The best time to transplant it is in early autumn or late spring.

4. Pothos

Pothos is a good absorber of formaldehyde and has high ornamental value. The stems naturally droop, which can not only purify the air, but also make full use of space. , adding lively lines and bright colors to the dull cabinets. Hydroponic pothos grows quickly and requires extensive cultivation and management. For specific hydroponics, it is necessary to select the branches and stems of pothos. Healthy and strong branches with aerial roots are the best hydroponic objects. In this way, the branches with aerial roots should be cut After planting, it can be quickly adapted to the hydroponic environment by placing it in clean water. It will take 15 to 20 days to grow water roots. Put the aerial roots into the water together. The aerial roots can also function as nutritional roots, absorbing water and nutrients. During the growth period, dilute the hydroponic fertilizer and spray it on the leaves to make the leaves more beautiful. Pothos has soft and elegant branches and colorful leaves. Small plants can also be planted in wall-mounted containers, allowing them to tilt and droop, like green curtains, fresh and elegant. Like potted pothos, hydroponic pothos also needs regular pruning to cut off overlong and disordered branches and stems to maintain a dense and orderly appearance.

5. Chrysanthemums

Chrysanthemums can decompose two harmful substances, namely formaldehyde present in carpets, insulation materials, and plywood, and xylene hidden in wallpaper, which is harmful to the kidneys. Not only that, it is also highly ornamental, with many potted varieties or land flowers to choose from. In addition, its petals and rhizomes can also be used as medicine. Long-term water management of chrysanthemums must be carried out in accordance with the principle of "timely watering during drought and timely drainage during floods". And make sure you have enough water before and after the pregnancy period.

Watering can also be combined with fertilization, and attention must be paid to "seeing wet and seeing dry", that is, it should not be half dry or half wet, nor should it be too dry or too wet. Also, spray the leaves with leaf water once every morning and evening. In addition to applying sufficient base fertilizer to chrysanthemums, top dressing should not be applied too much or too early, otherwise it will cause root damage and leaf fall. However, since the beginning of autumn, from the beginning of pregnancy buds to the time when buds appear, there should be sufficient fertilizer and water. Generally, thin bone flakes and sauce residue water should be applied once a week. When the buds are ready to bloom, apply superphosphate or 0.1% potassium dihydrogen phosphate solution once more to make the flowers more colorful. Water and loosen the soil in time after each fertilization to facilitate ventilation.

6. Monstera deliciosa

Monstera deliciosa occupies the first position in the rankings, absorbing 90% of formaldehyde, which can be said to be a very powerful purifier. device. In addition to absorbing formaldehyde, Monstera deliciosa can also effectively absorb benzene and other volatile harmful gases. Monstera prefers a warm and humid environment and avoids drought and direct sunlight, otherwise it will easily cause dead leaves. Monstera should be placed indoors or under a shade shed in summer, and should not be placed on a balcony where the sun is too strong to expose it to the sun, as this will easily cause it to die. When the temperature drops to 6 in winter, the Monstera should be moved indoors to keep warm. The Monstera deliciosa needs sufficient water, and the culture soil must be kept moist at all times. During the summer growth period, water once in the morning and once in the evening, and the leaves should also be sprinkled with water frequently to keep the leaves bright and the air moist. In winter, water evaporates slowly, so water once every 3-4 days. Daily watering is enough. Monstera is a plant that likes fertilizer, so you need to pay attention to fertilizing it properly. During the growth period of Monstera deliciosa, thin pancake fertilizer and water should be applied every half month. If the fertilizer is sufficient and appropriate, Monstera deliciosa will grow with pleasant leaf color.

7. One-leaf orchid

One-leaf orchid has a certain effect in absorbing formaldehyde, and also has a good absorption effect on hydrogen fluoride, and one-leaf orchid is particularly resistant to negative effects. It can still live in the light, and its adaptability is very good. One-leaf orchid can be cultivated in a bright room all year round, but it cannot be placed in direct sunlight whether indoors or outdoors. Short-term sunlight exposure may also cause leaf burn, reducing the ornamental value. One-leaf orchid has no strict soil requirements and tolerates barren soil, but it is better to have loose, fertile, slightly acidic sandy loam. When potting, you can use leaf humus soil, peat soil and garden soil mixed in equal parts as the substrate. One-leaf orchid should be fully watered during the growing season, keep the pot soil moist at all times, and spray water on the leaves frequently to moisten the leaves to facilitate the sprouting of new leaves. After the end of autumn, the amount of watering can be appropriately reduced.

8. Schefflera

Schefflera occupies the second position in the rankings, and can reduce the concentration of formaldehyde by about nine milligrams per hour. And it can convert nicotine and other harmful substances in the air into harmless substances. Palmwood grows well in an environment with high air humidity and sufficient soil moisture. Pay attention to the pot soil not being short of water, otherwise it will cause a large number of leaves to fall off. Water should be properly controlled under low temperature conditions in winter. If using plastic containers, pay attention to drainage. Keep the soil moist and water it in time before it dries out. When the weather is dry, spray the plants to moisturize them. During the rainy season, prevent water from accumulating in the pots. Schefflera has its peak growth season from March to September, so apply some compound fertilizer or cake fertilizer every 2-3 weeks. Mosaic and leaf varieties should not be fertilized too much (especially nitrogen fertilizer), otherwise the leaves will turn green and lose their original variety characteristics. Variegated leaf varieties require less nitrogen fertilizer to prevent the patches from fading or disappearing. Schefflera is prone to sprouting leggy branches, so regular attention should be paid to shaping and pruning the adult plants to keep the plant shape neat and beautiful. When old perennial branches grow too large, they can be pruned in combination with repotting every year before new shoots sprout, and the upper branches and leaves and part of the old roots can be cut off.
