Family cultivation and maintenance of Magnolia (Magnolia)

Cymbidium, also known as weeping pot grass, laurel orchid, hook orchid, folding crane orchid, Western Europe, also known as spider grass or aircraft grass, is a perennial evergreen foliage plant of Liliaceae.

Cymbidium is a perennial herb with tufted cylindrical hypertrophic fibrous roots and rhizomes. Leaves basal, strip to strip-lanceolate, long and narrow, flexible like orchid, 20Mel 45 cm long and 1-2 cm wide, tip long, acuminate; base clasping, inserted on short stem. The most important feature of Cymbidium is that mature plants will grow stems from time to time, the stem length is 30ml / 60cm, and plantlets grow at the apex. Flower pavilions slender, longer than leaves, curved; racemes simple or branched, sometimes clustered in clusters of 8 cm at upper nodes of inflorescence; flowers white, several clustered, sparsely scattered on inflorescence axis. The florescence is between spring and summer, and it can also bloom indoors in winter. At present, in addition to pure green leaves, there are three kinds of horticultural varieties: Magnolia, Golden Cymbidium and Phnom Penh. The edge of the first two leaves is green, while the middle of the leaves is yellow-white; Phnom Penh is on the contrary, and the edges of the green leaves are lined with yellow-white stripes. Among them, Cymbidium is an elegant indoor foliage plant because of its large plant type, broad leaves and soft leaf color.

Cymbidium is native to southern Africa and is widely cultivated all over the world. Its sex likes a warm, humid, semi-overcast environment. It has strong adaptability and is resistant to drought and cold. Instead of soil, it grows better in loose sandy loam. Light requirements are not strict, a ship is suitable for growing in medium light conditions, but also resistant to weak light. The suitable temperature for growth was 15 ℃ and 25 ℃, and the overwintering temperature was 5 ℃.

Cymbidium can be propagated by ramets. Except that the winter temperature is too low to be suitable for ramet, it can be carried out in other seasons. When potted plants were planted for 3 years, the dense potted seedlings were removed from the old culture soil and divided into two to several clumps when the pots were changed in spring. Cymbidium can also be propagated by small plants on the walking stem. In the growing season, the small plants on the stems are cut, planted in the culture soil or in water, and then transplanted into the basin after the small plants take root. In addition, seeds can be used for sowing, but-generally used less.

In potted cultivation, rotten leaf soil or peat soil, garden soil and river sand are often mixed with a small amount of base fertilizer as substrate. Change the basin every 2-3 years and re-prepare the culture soil. The fleshy root has developed water storage tissue and strong drought resistance, but it needs more water during the peak growth period from March to September, so it should be watered and sprayed frequently to increase humidity, and gradually reduce the amount of water after autumn to improve the cold resistance of the plant. During the peak growth period, dilute liquid fertilizer was applied twice a month. Nitrogen fertilizer is the main fertilizer, but Jinxin and Phnom Penh varieties should not apply too much nitrogen fertilizer, otherwise the line spot of leaves will not become obvious. Hanging orchid like semi-shady environment, if the light is too strong or insufficient, the leaves will easily become light green or yellowish green, lack of vitality, lose their due ornamental value, or even die; such as direct sunlight, dry air, the most likely to cause hanging orchid scorched, so it should be placed in a cool and ventilated place, and pay attention to maintain environmental humidity. Cymbidium is not easy to suffer from diseases and insect pests, but if the basin soil is stagnant and poorly ventilated, it will not only lead to rotting roots, but also may cause root rot, so attention should be paid to spray control.

Cymbidium is one of the most traditional indoor hanging plants. Its leaves are slender and soft, and the Diandian stem extracted from the leaf axil has small plants, hanging down from the basin, stretching and hanging, like flowers, evergreen all the year round; it is both firm and soft, shaped like a crane with wings spread, so it is called "folding crane" in ancient times. In short, its special shape constitutes a unique hanging landscape and three-dimensional beauty, which can play a chic embellishment effect.

Cymbidium is not only an excellent hanging foliage plant in the room, but also a good indoor air purification flower. Hanging orchid has a very strong function of absorbing poisonous gases, generally raising 1-2 pots of hanging orchid in the room, the toxic gas in the air can be absorbed completely, so the hanging orchid is also known as "green purifier".
