The advantages of planting flowers in China are shown in germplasm resources, climate resources, labor resources, market advantages and flower culture advantages. During the Tenth Five-Year Plan period, the flower planting area in China has reached 64, hectares, an increase of 326.7% compared with 15, hectares at the end of the Ninth Five-Year Plan period. Among them, Henan, Jiangsu, Zhejiang and Guangdong provinces have an area of more than 5, hectares, and Hebei, Shandong, Hunan and Gansu provinces have an area of more than 2, hectares. The flower area in China has accounted for one third of the total flower production area in the world. In 25, there were 2,586 flower markets and 64,98 enterprises in China, including 8,334 large and medium-sized enterprises with planting area over 3 hectares or annual turnover over 5 million yuan, 1,251,313 flower farmers, 4,41,95 employees and 132,318 professional and technical personnel. At the end of the Tenth Five-Year Plan period, the national key flower producing areas were initially formed, and the variety structure was further optimized. The regionalization industry has formed the southern tropical and subtropical flower producing areas focusing on Guangxi, Yunnan, Sichuan, Jiangsu, Zhejiang and Hainan. Southern tropical foliage plants producing areas with emphasis on Guangxi, Guangdong and Fujian; The number of viewing production areas with Zhejiang, Sichuan, Henan and Hebei as the focus; Green seedling production areas mainly in Anhui, and northern flower production areas mainly in Beijing, Shandong and Hebei; Northeast flower producing area with Liaoning as the center. Among them, fruit seedlings are particularly popular, and tropical fruits in China are mainly distributed in Guangxi, Guangdong, Fujian and Hainan. Ling shan, Guangxi, is one of the main fruit seedling producing areas, and has the title of "Hometown of Litchi". It mainly produces fruits and seedlings: Litchi, Mango, Longan, Banana and so on. Seedling production areas are extensive. Global Fruit Seedling Planting Farm _ is the largest seedling farm in ling shan, Guangxi. Fatong, Tilia amurensis, Ulmus pumila and Aesculus esculenta are internationally recognized as the four first-class street tree species, which are well-known garden shade and landscape trees, and are known as the king of street trees. It is understood that in order to avoid random selection of tree species in urban greening, the Construction Department of Jiangsu Province and the Institute of Botany of Chinese Academy of Sciences jointly completed the survey of "Suitable Plants for Urban Landscaping in Jiangsu Province". According to the results of the survey of 419 species of trees and shrubs in the urban greening system of the whole province, Fraxinus fargesii is still the first choice for urban street trees because of its strong adaptability to urban environment and many other advantages. It can be seen that the fast-growing paulownia, as an excellent new variety of paulownia, will have a very broad development prospect.

fast-growing paulownia is suitable for planting in vast areas of China, as far north as Lushun, Beijing, Shijiazhuang and Taiyuan. Northwest to Xi 'an, Wugong and Tianshui; Southwest to Chengdu and Kunming; South to Nanning and Guangzhou. Although the urban greening rate has increased, the shading rate has shown a downward trend, which is exactly landscape-oriented rather than people-oriented If landscape designers pay attention to trees, shrubs, flowers and plants, and give priority to the development of large trees, so that greening can be achieved in the city and the forest in the city, close to the masses and close to life, then the fast-growing paulownia is the ideal first choice tree species.

According to the introduction, the fast-growing paulownia has both the characteristics of common paulownia and its incomparable remarkable characteristics. The characteristics of this variety, such as less balls, disease resistance, ecological effect and concentrated defoliation time, meet the requirements of environmental protection. Cultivating this variety can shorten the period of leaving the nursery and quickly alleviate the demand for large-scale seedlings in greening. In addition, this variety is suitable for cutting and planting, which can effectively increase the number of vehicles and reduce the transportation cost. Moreover, it does not need soil balls, and all sizes can be planted in bare roots, and the survival rate can reach over 98%. The greening effect can be improved with low cost and high survival rate. To sum up, this variety has great development prospects and high research value. If the research can be deepened in the topics of no-ball, standardized cultivation, plastic pruning and so on, this exotic tree species with a history of 1 years introduced into China can also be returned to its native land, so that the tree posture of fast-growing Fraxinus can be displayed in the world landscape.
