Canna has a strong absorption of sulfur dioxide. Perennial herb Perennial. Easy to cultivate, hi sunny and warm climate, not cold. Poor soil requirements, fertile, deep, well-drained sandy loam is best. Fear of earthworms, soil water easily rot. Potted plants are available for short and large flower varieties. In late April, the tubers of the canna are buried in pots with a diameter of about 40 cm. Before planting the pelvic floor, a combination of nitrogen and phosphorous organic fertilizer is used as a base fertilizer. During the growth and flowering period, several compound liquid fertilizers (applying chicken manure or ramie water to make mash) are required. After the planting, watering should not be done. It should be placed in a place where there is plenty of sunshine and air circulation. If fertilizer is insufficient or phosphorus and potassium fertilizers are lacking, the plants are weak and only have long stems and leaves, and they have little or no flowering. After flowering, they must cut off the calyx and apply liquid fertilizer. Evergreen can effectively remove trifluoroethylene contamination. Liliaceae are perennial grasses. The rhizomes are short and thick, with fibrous roots at the nodes, leaf basal, band-like or oblanceolate, terminal spikelike inflorescences, many cultivars, including Phnom Penh, silver margin, and variegated evergreen. In the semi-shade environment, it is placed in a shaded place in the summer to avoid strong light. Every March to April, it can be changed once. When changing the basin, old roots and dead leaves should be removed and planted on an acidic soil added with base fertilizer. After putting on the basin, it should be placed on the shade for a few days. Watering should be done so that the pot soil does not dry and it is rather dry, and it should not be too wet. In addition to the need to keep the basin soil moist in summer (in the hot climate, the water should be sprayed around the flowerpot early and late), watering in spring and autumn should not be overworked. During the growth period, 2 to 3 decomposed thin liquid fertilizers can be applied. Potted earth is usually cultivated in garden soil, but it is best to have sandy loam rich in humus and loose water permeability. Another tiger eye evergreen, Guangdong evergreen, mosaic evergreen, etc., can be used for indoor potted plants. Monstera has a strong ability to absorb carbon dioxide at night. Also known as Penglai banana, Araceae perennial evergreen lianas. There are also variegated leaves, slanted leaves of Monstera and so on. Its stems are stout, with many sections resembling bamboo, and a large amount of fleshy roots. Leaves alternate, leaves nearly round, large, young leaves heart-shaped, without perforation. After being grown up, it has a large number of oblong holes and deep cracks on its large blades. Native to South America, hi warm, moist environment, hi half shade, avoid direct sunlight, hi fertile, sandy soil rich in humus. Pellets can be used for 2 parts of rot leaf (peat), 1 part of garden soil, 1 part of river sand, and a small amount of basal fertilizer. The suitable temperature is 20°C to 25°C, and the wintering temperature is more than 8°C. During the growing season, a thin liquid fertilizer (such as cake and water) can be applied once a month. Normally, it will not dry when wet, and when the air is dry, it can spray water to the foliage and the ground. Plants need to be given scaffolds or climbing along the objects after they grow up. Reproduction is mainly based on cuttings. In April and May, stem segments with two or three sections can be cut. After removing aerial roots, they are erected and inserted into the primal sand basin. A section of the sand is exposed outside. Department, moisturizing, buds can be rooted one month. In addition, plants that can absorb carbon dioxide at night include cactus, clams, peony, fairy pillars, bromeliad pineapple, torchbane pineapple, etc., and agave orchids. Plants that can purify the air include pomegranates, carnations, rose, rose, daisies, peony, and sedges. Indoor greening plants should be properly matched to be more conducive to our physical health.
