As a part of Hunan seedling industry, color seedlings can not be separated from the environment of the whole greening market. At present, the external conditions for the development of Hunan seedling industry are still superior, and the market is unprecedentedly prosperous with great potential. Even in the next decade after hosting the Olympic Games and the World Expo, Hunan seedling industry will still be a sunrise industry due to the pull of major national projects and the continuous pull of urbanization. However, at present, the area of seedlings is expanding rapidly, and some varieties have escape sequences, so they cannot develop blindly. As a part of new seedling varieties, color seedlings will develop and become more and more important under the strong market demand. Some experts predict that colored seedlings should account for 15-20% of the total green seedlings. The development prospect of colored seedlings is broad, which is not only the bright spot in the current market, but also more vital than traditional varieties. Since the reform and opening up, especially in the middle and late 1990s, China's green seedling industry has developed rapidly around the six major projects of urbanization and forestry. The scale of production has expanded rapidly and the overall structure has developed in a good direction. The main driving forces for the development of Hunan seedling industry in the future are as follows: 1. The sustained and rapid growth of national economy is the fundamental driving force for the rapid development of Hunan seedling industry. China is one of the fastest-growing countries in the world in the past 20 years. In the next 20 years, China's economy will continue to develop rapidly and healthily, which will not only ensure the sustained and rapid development of Hunan's seedling industry, but also provide an opportunity for the further development of newly-started colored seedlings. Second, the acceleration of urbanization and the rise of real estate industry are the accelerators for the rapid development of Hunan's seedling industry, while big cities such as Beijing and Shanghai pay more and more attention to the seasonal variation characteristics of colored trees and the role of beautifying colorful cities, and other small and medium-sized cities will also be affected. By 20 10, the green rate in urban planning area and built-up area will reach over 35%, the green coverage rate will reach over 40%, and the per capita green space will reach over 10 square meter. However, at present, the green coverage rate of many urban built-up areas is still relatively low, and urban landscaping needs a large number of seedlings. With the acceleration of urbanization, the urban population and the scale of urban land are expanding rapidly. New towns and urban built-up areas have promoted large-scale landscaping construction, thus promoting the development of Hunan seedling industry. In addition to the steady growth of public green space, residential areas, units, protective green space and ecological greening have also developed rapidly. With the rapid development of the real estate industry, people pay more and more attention to improving the living environment. Real estate developers believe that the quality of real estate environment is one of the key factors for the success of real estate project development. The garden landscape of residential areas has been highly valued by real estate developers, and the market for garden construction of real estate projects has expanded rapidly. The introduction of color-leafed tree species can improve the level of green landscape and the level of ancient and famous trees. For example, according to the greening plans of Shanghai, Beijing and other cities, the demand for green seedlings in these areas will be very strong in the future. In fact, not only the "Green Olympics, Color Beijing" in Beijing in 2008 and the 20 10 color Expo in Shanghai, but also the greening development of other big cities and small and medium-sized cities in China is also very rapid. At present, there are about 1 000 cities in China. Urban greening and beautification is one of the key tasks of urban modernization and upgrading urban taste, which provides a broad development space for China's green seedling industry. The construction of small towns and new countryside is another potential market for the development of green seedling industry. Three. Major infrastructure construction Major infrastructure construction (such as traffic construction) will stimulate the development of supporting landscaping and environmental construction projects. Green passage and urban forest construction have become another new growth point of green seedling market demand. In recent years, China has invested heavily in major infrastructure construction, and the investment in fixed assets has grown strongly. The scale of road greening and supporting landscape construction is expanding, which requires improvement. "The construction of green passages along railways and highways requires a lot of garden plant materials for greening and landscape construction. The rapid rise of tourism and leisure industry will greatly stimulate the construction of landscape architecture and the beautification of tourist cities. In Zhejiang, Jiangxi and other provinces, the construction of ecological province and ecological zone has been regarded as the development goal. Fourth, the national income level has been continuously improved, and the Engel coefficient has been continuously reduced. The continuous improvement of national income level, the continuous decrease of Engel coefficient and the continuous improvement of environmental awareness have laid an ideological foundation for the development of garden industry. Family greening and private garden gardening will also start quickly, and the market scope of Hunan seedling industry will be greatly expanded. In foreign countries, such as Canada and other North American countries, domestic garden plants have accounted for more than 50% of the whole market. To sum up, the external conditions for the rapid development of seedling industry in China and Hunan are basically mature and will enter the initial and take-off stage. It is predicted that in the next few years, the seedling industry in China and Hunan will develop rapidly at an annual rate of about 25% to 30%. Five, Hunan color seedling industry development prospects. 1. Greening has become "colorful" and the market demand is great. Because the current greening construction has changed from simple greening to urban color beautification, new landscape engineering and design need colored tree species, and the old green space reconstruction also needs colored tree species. It can be predicted that the proportion of colored-leaf trees in the city will gradually increase, and it is expected to reach 15-20%. If the old green space is not upgraded, the demand for colored seedlings will reach 4,000 hectares (from 2003 to 20 10, the average annual increase of urban green space is more than 20,000 hectares) only according to the annual increase of green space. Hunan color seedling industry is in the ascendant, in the ascendant. However, the capacity of colored seedlings in the market is still very small, which is basically in short supply, especially for excellent colored tree varieties. Some experts predict that in the next decade, large-scale seedling raising and color-leafed tree species will not be out of date. 2 in line with the national industrial policy, you can apply for research funding. Governments and departments at all levels attach great importance to environmental protection and forestry development, and the introduction of color-leafed tree species is of great benefit to enriching urban tree species and adding colorful urban landscapes. You can apply for scientific research funds to support development. 3. The investment return rate of colored seedlings is higher than that of ordinary seedlings, the whole market is on the rise, and the investment risk is relatively low. The promotion of new varieties is usually accompanied by relatively high profits and long development prospects, while imported colored seedlings are usually introduced for a short time and are still on the rise, with relatively low investment risks. Different from other varieties, the choice of colored seedlings is the highland of greening tree species, which is a good choice for those businesses who want to accelerate their development and surpass ordinary seedling enterprises, such as social capital who have newly entered the seedling industry in Hunan.
