what kind of tree is it? Can potted plants live?

Judging from the morphology of the plants in the picture, this plant is the five-pointed maple, also known as five-pointed maple, Acer mono, Acer mono, Acer mono, Acer mono, Acer mono, which is a variety of Hamamelidaceae and Acer mono.

The fruiting period is August. Mainly distributed in the middle and lower reaches of the Yangtze River and its south and northern India. Flowers, roots and leaves are medicinal.

Third, the morphological characteristics

Shrubs, sometimes small trees, have many branches and star hairs on their branchlets. The leaves are leathery, oval, 2-5cm long and1.5-2.5cm wide, with sharp apex, blunt base, unequal sides, slightly thick or bald at the top, dark green and dull after drying, with star hairs at the bottom, slightly grayish white, about 5 pairs of lateral veins, obvious at the top and protruding at the bottom.

Red maple trees are mostly natural, spherical and carved. The natural height shall be measured by natural shape and spherical shape, and the natural crown width and landscape shape of modeling pile shall meet the requirements of full modeling handle, layering and simple Gu Zhuo, and the sum of main poles shall be added in turn for multi-pole measurement.

Fourth, the growth environment and distribution.

Produced in Hunan and Guangxi, widely cultivated in southern China. Like light, slightly tolerant to shade, but the color of leaves turns green on cloudy days. Strong adaptability and drought tolerance. Like warmth and cold resistance. Strong germination, strong branching ability and pruning resistance. It is barren-tolerant, but suitable for growing in fertile, moist and slightly acidic soil.

Breeding method of verb (abbreviation of verb)

1 grafting

Cutting and budding are mainly used. Grafting can be carried out in February ~1October, cutting is better in spring, and bud grafting is suitable in September ~1October. Take small and medium-sized plants of Ailanthus altissima as rootstock for multi-head grafting, strengthen the management of water, fertilizer and pruning, and make them leave the nursery within 1 year.

2 cutting

It can be carried out from March to September. Choose loose loess as cutting substrate, ensure that the cutting substrate is ventilated and high in air humidity, keep warm but avoid direct sunlight, and pay attention to ventilation of cutting environment. Under warm and humid conditions, the cuttings of Acer mono formed a red healing body within 20-25 days, and after 1 month, 3-9 new roots grew, with a root thickness of 0. 1cm and a length of1~ 6 cm. The propagation coefficient of cutting method is large, but its growth potential is weak and it takes a long time to leave the nursery. The seedlings grafted by many heads grow vigorously and come out of the nursery quickly, but they need more labor. Cutting the tender branches from May to August, using the semi-lignified branches of that year, cutting them into 7 ~ 10 cm long cuttings, and inserting them into the soil1/3; The matrix of the inserted bed can be perlite or mixed with 2 parts of river sand, 6 parts of loess or mountain mud. After transplanting, build a shed for shade, spray water in time to keep the soil moist, and take root in 30 ~ 40 days.

3 sowing

When sowing in spring and summer, the seed germination rate of Acer truncatum is high, and it germinates about 25 days after sowing. 1 year can grow to 6 ~ 20 cm high, and 3 ~ 6 branches germinate. The red meat quality of Acer truncatum seedlings must be carefully managed in the early stage, and can only be extensively managed after the roots are lignified and browned. Sexual reproduction is generally not used for seedling production, but for the breeding research of Acer truncatum, because Acer truncatum has a long seedling stage and slow growth, and Acer truncatum seedlings (atavism) appear. Generally, the seeds are harvested in June 5438+ 10, and planted in winter in June 5438+065438+ 10, or the seeds are sealed and stored until the following spring. After scraping the sand, the seeds were drilled in a semi-sandy seedbed, and the germination rate was low about 25 days after sowing. The height of 1 year-old seedlings can reach 6 ~ 20 cm, and 3 ~ 6 branches sprout. After 2 years, you can leave the nursery for permanent planting.

Six, the main application value

1 View

Acer truncatum is luxuriant in foliage, graceful in posture, resistant to pruning and twisting, and can be used for hedgerows and making stump bonsai. When the flowers bloom, the trees are full of red flowers, which is very spectacular. Red maple is an evergreen plant with bright red leaves. When different strains mature, their leaves are different in color, pattern and color, and their leaves are also different in size. In landscape application, the different effects brought by leaf color and leaf size are mainly considered.

Acer truncatum is a precious native colorful ornamental plant in Hunan, which has strong ecological adaptability, pruning resistance and easy modeling. Widely used in colored fences, flower beds, bush balls, small colored trees, pile landscape modeling, bonsai and other urban greening and beautification.

2 Economy

Acer truncatum has a history of more than 20 years in China, and Hunan is the central producing area. In 2004, the province's production area was 3,500 hectares, with an annual output of 500 million seedlings and annual sales of 600 million yuan. After years of popularization and application, in 2004, the production area of red clover in China reached 6000 hectares, with an annual output of 800 million seedlings and an annual sales of 900 million yuan. Products are sold to more than 20 provinces and cities in China, and exported to Japan, South Korea, Singapore, the United States, the Netherlands, Britain, France, Germany and Italy, becoming one of the characteristic products of China's flower industry. ?

Acer is a variety of Acer in Hamamelidaceae, and it is an evergreen shrub or small tree. It is a special product of evergreen broad-leaved forest with an altitude of 100 ~ 400 meters in Luo Xiao Mountains at the junction of Hunan and Jiangxi. It was discovered and named by the late famous forester Professor Ye Pei Zhong in Changsha Tianxin Park in the spring of 1938. After examination, the model specimen collection tree is a wild plant transplanted from Dawei Mountain in Liuyang in the spring of 1935. This tree still exists, with a height of 5m, a DBH of 20cm, a crown diameter of 42m2 and an age of about 150 years. Due to years of excavation, wild resources are on the verge of extinction and are listed as key protected plants in Hunan Province. ?

Hunan has used the wild resources of Pterocarya stenoptera for more than 70 years. In the early 1930s, farmers in the Dawei Mountain area of Liuyang dug wild seedlings and sold them to Changsha, Xiangtan and Zhuzhou. Some garden departments in the province also come to Liuyang to purchase wild seedlings. 1963 Changsha Yuelu Park and other units successfully raised seedlings by high pressure method; 1978, Changsha Martyrs Park successfully used seeds to raise seedlings, but the genetic stability of seedlings was not strong. 15.8% returned to ancestors and became Zelkova schneideriana, and seeds were rarely used to raise seedlings in production. Changsha 1982 Nursery successfully used tender bud cutting to raise seedlings. Because the cutting seedlings can keep the excellent characteristics of the female parent, they can be cut many times in one year and propagated in large quantities, so this technology has been widely used in seedling production since the 1980 s. Large-scale seedling raising began in He Yong Town, Liuyang. 1983, local farmers used the rich wild resources of Pterocarya stenoptera from He Yong Town to Daweishan, and began to produce a series of products on a large scale, such as cutting seedlings, transplanting seedlings, bush balls, bonsai, ancient pile grafting trees and so on, which promoted the formation and development of Pterocarya stenoptera industrialization in the whole province. 1999 10, the organizing committee of China's hometown of specialty recommended publicity activities awarded Liuyang the honorary title of "hometown of five-pointed maple in China", which greatly improved the popularity of five-pointed maple at home and abroad in Hunan, and became one of China's characteristic flower brand products.
