This is Pterocarya stenoptera, also known as Camptotheca acuminata and Yuchun, belonging to Pterocarya of Araceae. Feather rosewood is strong, unique in leaf stage and very resistant to shade. It is one of the most widely used indoor foliage plants in families and public places.

Feather velvet is a kind of velvet. There are abundant varieties of evergreen velvet in the tropical rain forests of South America. 1in the middle of the 8th century, Meconopsis prostrate was introduced to Britain, and then 3 1 species was cultivated in Holland, Italy, France and other countries. At the same time, cultivation began in America, especially in America. 1888, Italy bred a bronze shield by crossing glossy velvet (P. Lucidum) with leather velvet (P. Coriaeum). 1936, red-leaf evergreen velvet (P.×mandaianum) is a hybrid of domestic and common pilose antler grass in the United States. Later, Bamboo Garden Company in Florida introduced a new variety of Emerald Buke in 1975, and Emerald King in 1976, which made the market share of evergreen velvet increase day by day.

So far, many famous international flower companies have pushed the production of crawling velveteen to industrialization. Among them, Hermite International Company, Yigai Trading Company and Grassby Plant Experimental Center in the United States, Benze Nursery, Goya Nursery, Agri Agricultural Center and Israel Biological Plant Breeding Center in Israel, Menwan Company in the Netherlands and burbank Biotechnology Center in Australia provide high-quality seedlings, cuttings and tissue culture seedlings for the world's velvet producers.

Although the cultivation time of Meconopsis prostrata in China is not long, it has developed rapidly. Before 1980s, there were few varieties of Meconopsis prostrate, which were only cultivated in botanical gardens and parks, and rarely seen in public places. Today, the planting of Meconopsis prostrate has spread all over the south, and there are many varieties. Especially, ruby (P. imbe) and emerald (GreenEmerald) are widely cultivated and can be seen everywhere in families and public places. Evergreen velvet has become an important indoor foliage plant.

The leaves of red taro are covered with Josephine, and the leaves are purple-brown. P.evansii, with broad oval leaves, elephant ears, length of 1 m, dark green and light pink leaves, is the most beautiful variety in chrysanthemum.

Majestic, arrow-shaped leaves, dark copper green, red back, red stems and petioles. Red Duchess, heart-shaped leaves, dark green, red back and red petiole. Jin Fenghua has a long heart shape, dark yellow leaves, red leaf margin, short petiole and golden yellow.

Biological characteristics: Phyllostachys pubescens is native to Brazil and likes warm, humid and semi-cloudy environment. Strong adaptability, intolerance to low temperature and fear of drying.

The optimum growth temperature of pterocarpus pinnatifida is 18 ~ 28℃, with 2 1 ~ 28℃ from March to September and 18 ~ 2 1℃ from September to March next year. The temperature is not lower than 8℃ in winter, and it can tolerate the low temperature of 5℃ in a short time, and some varieties of Meconopsis prostrate can tolerate 2℃.

Meconopsis pinnatifida grows in tropical rain forest area, which requires high water content. During the growing period, the basin soil should be kept moist, especially during the high temperature period in summer. In addition to watering every day, we should also spray water on the leaves frequently to keep the air humidity at 70% ~ 80%. However, if the temperature is lower than 15℃, the watering amount should be reduced.

Feathered green velvet can resist shadows and strong light. When exposed to strong light, leaves turn brown and aerial roots dry. The variegated leaf species prefer semi-shade and strong light, and the leaf color is more vivid. The light intensity range is1.5000 ~ 35000 lux. Pterocarya pinnatifida has strong shade resistance, which can be stored for 60 ~ 90 days in the bright room, 30 days in the dark room and 15 days in the dark.

The soil is fertile, loose and slightly acidic sandy loam with good drainage. Potted soil is usually mixed with garden soil, peat soil, humus soil and coarse sand.

Common propagation methods include cutting, sowing, rameting and tissue culture.

Cutting propagation: May-September is the best. Cut 2-3 strong stems, insert them directly into coarse sand or water moss, keep them moist, and take root 20-25 days after cutting.

Seeding and propagation: Seeding is carried out in an indoor seedling tray, and the optimum temperature for germination is 25% ~ 30%. After sowing, seedlings emerge in 10 ~ 15 days, and the seedlings are moved to 8 cm pots when they are 5 ~ 6 cm high.

Propagation by ramets: when the plant grows taller, the lateral branches with aerial roots can be directly cut into pots or cored first to promote the long branches. When the lateral branch 15 ~ 20cm, the potted plants with aerial roots can be cut off.

Tissue culture and reproduction: At present, in the United States, Israel, Australia and other countries, tissue culture is used to reproduce a large number of evergreen velvet antler. Shoot tips or axillary buds were used as explants. After routine disinfection, it was inoculated on MS medium supplemented with 4 mg/L 6- benzylamino adenine and 2 mg/L indoleacetic acid, and callus and adventitious buds grew after 6-8 weeks. Then the adventitious buds were transferred to 1/2 ms medium containing 2 mg/L indoleacetic acid, and new roots were induced in about 3 ~ 4 weeks to form complete plantlets.

Potted hairy vines generally use 20 ~ 25 cm cultivation management pots. The bottom of the basin should be padded with broken tiles and bricks, which is beneficial to the growth and development of roots. Fertilize 1 time every half month during the growth period or use "Huiyou" 20-20-20 general fertilizer. And often spray water on leaves and the ground to increase air humidity. With the increase of new leaves, the old leaves at the base gradually turn yellow and need to be cut off in time. Plants grow rapidly and need to change pots every spring. Adult plants can change pots every two years 1 time.

Leaf spot and shoot blight often occur in pest control, and 500 times of 65% zineb wettable powder can be sprayed. Poor ventilation, stems and leaves are vulnerable to scale insects and red spiders, and 40% omethoate EC can be sprayed with 1000 times solution.

Postpartum treated creeping green velvet with handsome green leaves. Potted plants are suitable for indoor hall decoration, especially for music teahouses and hotel lounges, adding a quiet and leisurely atmosphere. For example, a large basin of green velvet with feather-split rattan is matched with the lobby of hotels, airports and commercial buildings, showing the quaint, majestic and vigorous momentum in the wilderness. Rosewood is sensitive to ethylene during transportation, which often leads to leaves turning gray, yellow and wilting. Therefore, in addition to maintaining the temperature of 16℃ and the relative humidity of 80% ~ 90% during storage and transportation, silver thiosulfate 1 time is also used 15 days before the market, which can reduce the harm of ethylene to evergreen.
