Yucca is a perennial thick green plant with beautiful flowers and leaves, strange leaves, sword-shaped leaves, towering stems when blooming, white flowers, a variety of white flowers drooping like bells, graceful and pleasant fragrance, is a good garden ornamental trees, but also a good material for fresh cut flowers. Now let's take a look at the knowledge of Silan.

1. Introduction of silk orchid

Silk orchid alias soft-leaf silk orchid, hairy edge silk orchid, foreign pineapple, for Liliaceae, silk orchid plant. National flower of Seychelles having short or inconspicuous stems. Leaves near rosette cluster, hard, nearly sword-shaped or strip-shaped lanceolate, flower (fruit) stage, summer and autumn.

Yucca is native to North America and is now widely cultivated in the open field in warm areas. Yucca is often planted in the center of flower beds, slopes, buildings, roadsides and hedges. Yucca leaf fiber is white, tough and water-resistant, which is called "white hemp brown" and can be used as a cable. Body hormones can also be extracted from leaves. Yucca is the national flower of the Seychelles. Yucca is widely used in road greening, courtyard, landscaping and protective isolation. It has strong resistance, wide adaptability, evergreen all the year round and high ornamental value. it is an important tree species for landscaping, and the leaf fiber can make rope.

2. Culture methods of Yucca

Matters needing attention in culture

The main results are as follows: 1. The plants bred by cuttings and individual plants should be dug up and planted with lodging soil. As long as they are watered several times, they can survive. Daily management should pay attention to proper soil cultivation and fertilization to promote the extraction of inflorescences.

2. Saprophytic leaves or peat soil with good drainage and high humus content.

3. Like warm and bright, but avoid direct sunlight and are not resistant to cold. North China is suitable for pot planting, overwintering indoors or in cold rooms, and the temperature is kept at 5 Mel 10 ℃.

4. Like humidity, you should fully water outside in summer, but avoid stagnant water, and reduce the amount of water according to the temperature in winter; if the air temperature is too low, it will make the edge of the leaf yellow; it can resist drought and does not require spraying water to the leaf surface or around the plant in summer.

5. Change the basin once in 1-2 years, and the pot change can be carried out in spring; fertilize once every half a month during the growth period from March to August; after flowering, all inflorescences can be cut off to maintain plant shape and make terminal buds continue to develop; when dead leaves and stumps are found, they should be pruned in time to keep them clean and beautiful. It should be pruned properly in winter to clean up the withered branches and leaves, which is beneficial to flowering in the coming year.

6. there are few diseases and insect pests, and the room temperature in winter is too high, too dark, the air is blocked, and it is easy to cause insect pests, so we should improve the environmental conditions immediately and take measures to prevent and cure the disease.

Third, the function and use of silk orchid

1. Ornamental value

Ornamental plants with beautiful leaves and flowers, often planted in the center of flower beds, in front of buildings, in lawns, poolsides, slopes, buildings, roadsides and hedges. The leaf fiber is white, tough and water-resistant, which is called "white hemp brown" and can be used as a cable. Somatic hormones can also be extracted from leaves. Silk orchid is the national flower of the Seychelles.

two。 Purify the air

Yucca has strong resistance and absorption ability to harmful gases such as sulfur dioxide, hydrogen fluoride, chlorine, ammonia and so on. The results showed that when the average daily concentration of sulfur dioxide was 0.1 ml / m3, many trees such as juniper, heather, Yingchun, paulownia and so on showed serious symptoms, while Yucca was still tall and strong. Yucca also has a strong ability to absorb hydrogen fluoride, according to the determination, 1 kg of dried leaves can absorb 266 mg of fluorine. In addition, Yucca has a certain resistance to ammonia and ethylene, so Yucca should be planted in heavily polluted areas.

3. Ecological value

Yucca has a good function of purifying air, and has strong resistance and absorption ability to harmful gases such as sulfur dioxide, hydrogen fluoride, chlorine, ammonia and so on. The results showed that when the daily average concentration of sulfur dioxide was 0.15ml/m3, many trees such as juniper, heather, Yingchun, paulownia and so on showed serious symptoms, while Yucca was still tall and strong. Yucca also has a strong ability to absorb hydrogen fluoride. It is determined that the dried leaves of 1kg can absorb fluorine 266mg. Yucca has a certain resistance to ammonia and ethylene, and can be widely used in polluting industrial and mining enterprises.

4. Economic value

Yucca extract is a new type of feed additive, which plays an important role in promoting the health and high yield of livestock and poultry, improving the digestive tract environment, improving the quality of meat products, promoting the absorption of nutrients, and improving the utilization rate of feed. in particular, Yucca extract has a unique nitrogen fixation ability, which has a significant effect on reducing the concentration of harmful substances such as ammonia, hydrogen sulfide and dung odor in livestock and poultry feces, and improving the feeding environment.

The above is the knowledge of silk orchid. I hope I can help you.
