Flowers that can purify the air (top)

Regardless of harmful gases such as formaldehyde and benzene emitted from construction and decoration materials, or TVs, computers, etc., the reduction of negative oxygen ions will cause people to feel uncomfortable. If you can grow some flowers indoors, you can not only beautify the environment, but also absorb harmful gases and act as an air purifier. Here are some brief introductions: Chlorophytum is highly capable of absorbing toxic chemicals such as formaldehyde, carbon monoxide, and nitrogen peroxide in the air. Alias ​​Lanlan, fishing blue, Liliaceae perennial grass. Cylindrical fleshy roots, leaves basally, linear-lanceolate, ca. 1 to 1.5 cm in width, calyx drawn from leaf axils, and litchi, descent to apex, apex and node with many rootings Strain. Racemes, florets white, flowering from March to June. Common varieties are Phnom Penh, gold heart, silver edge, silver heart spider and so on. Native to South Africa, it has a strong natural environment, strong adaptability, luxuriant growth and easy cultivation. Hi warm, moist half shade environment, intolerable cold and heat, suitable temperature 15 °C to 25 °C, winter more than 10 °C is appropriate. Happy fertile, well-drained, humus-rich sandy soil. Pellets can be used 1 rot leaf soil + idyllic soil 2 + sand 1 + a small amount of farmyard Fertilizer mixture. Usually see the dry water, often keep the basin soil moist, dry season can be sprayed to the foliage, to prevent the yellowing of leaves or leaves dry. Monthly application of thin fertilizer once, such as topdressing compound fertilizer, one can not be too much, you can apply a few grains, or easy to burn roots. Stop fertilizing in winter, basin soil should be partial dry. The ramets can be used for breeding, or young plants on litchi can be directly cut and planted separately. Whole plant can be used as medicine. Pittosporin absorbs photochemical smog, dust and soundproofing. Also known as schisandra sinensis, evergreen shrubs or small trees in the seaweed family. Pots are 0.5 meters to 1.5 meters high. Leaves leathery, shiny, terminal umbels, flowering from April to June, white or slightly greenish flowers, aromatic. Sexual warmth, moist environment, hi sunshine, but also resistant to semi-negative, requiring the loose fertile soil. 2% of leaf or peat soil + 1 part of garden soil were mixed with potted plants and used as basal fertilizer. In the growing season, the leaves are often sprayed with water. The watering needs to be dry and wet, and the thin and thin pancakes are applied before and after flowering. Hi enough light, the wintering temperature is greater than 5°C, control the watering when the room temperature is low in winter. Pittosporum has strong branching ability and is resistant to pruning. It should be trimmed and pruned from the seedlings, topping it, and triggering lateral branches. The crown of the tree is often rounded. Potted young plants can be changed once a year, and adult plants can be grown for about 2 years. In the south, more seeds are planted in the north. The cuttings were best in the rainy season. Cut branches of semi-lignified wood that were used for cutting in the year, shaded and watered after plugging in, and callus and sprouting new roots can be grown in about one month. Aloe can reduce the pollution of benzene and formaldehyde and increase the concentration of negative oxygen ions. Can also be used for anti-inflammatory, treatment of bruises and so on. Liliaceae are perennial grasses. The fleshy leaves emerge from the cylindrical fleshy stems. There are many varieties, such as Aloe arborescens, Aloe vera, Aloe vera and so on. The racemes are drawn from the leafy stalks and grow upright. The flowers are orange and yellow with red spots. Hi warm and humid weather conditions, not cold, winter room temperature is not less than 5 °C. Strict requirements on the soil, resistance to drought and salinity, good drainage, fertile and sandy loam. Hi sunshine, impatient shade, shady environment or often picking leaves, do not love to blossom. Garden soil 2 parts + river sand 1 part + humus soil 1 part + a small amount of basal fertilizer (such as decomposed manure, chicken, duck dung, etc.) can be mixed into potted soil. In the vigorous growth seasons of spring, summer and autumn, the basin soil should be kept moist, but no water can accumulate. During the growth period, cooked thin pancake water or rice water can be applied 2 to 3 times. Stop fertilizing in winter, reduce watering, otherwise it is easy to rot. Commonly used cuttings, breeding methods. Cut the small lateral branch between the base of the main stem or leafhopper, 10 cm to 15 cm long, dry for 1 day to 2 days, insert it into the river sand, spray a little water, take root from 20 days to 30 days, and cut off the main trunk. Cuttings. The ramets can be carried out in the early spring in conjunction with the change of pots. Cutting off the new plant around the mother plant and the underground stem of the mother plant and planting a new plant can be done. This method has a low propagation coefficient. Strongly growing plants can be changed once every 2 to 3 years in spring, removing old pot soil and replacing with new nutrient soil.
