Preliminary Study On Different Areas China Fir Cultivation System

Cultivation system is an important problem in the forest cultivation, it is essential to how scientific and reasonable planting. The construction of scientific and reasonable cultivation system of Chinese fir can make its economic, ecological and social benefits for the sustainable development in an all-round way. From the level of current research and practice, research on Chinese fir cultivation system in the breadth and depth is relatively weak at present. Therefore, this study proposes the construction of different producing areas of Chinese fir cultivation system project aims to understand the basis of Chinese fir cultivation condition on distribution method according to natural conditions, productivity and division of areas in different site conditions of Chinese fir in different areas to realize the division of cultivation system induction and construction, provide reference theory and method in the future so as to cultivate Chinese fir and other species and sustainable development.The main contents of this research are as follows:The first chapter discusses the background, goal and significance of this research, the research characteristics and innovations and related concepts; The second chapter mainly carries on the review of the domestic and foreign forest cultivation system of literature, to understand the past research route of the field and the latest developments. Analyzed the literature of Chinese fir cultivation system and agricultural farming system, so as to accumulate theory and the method of the study required by these literature reviews, and then determined the research ideas and research emphasis of this study; The third chapter mainly through a comprehensive consideration of the comparative analysis of the forestry management mode and social background of Chinese Fir Growth, development, put forward the guiding ideology, principles and basis of this research; The fourth chapter on the basis of previous studies, from the perspective of natural conditions, different regions and different site conditions productivity division to construct theory system study on cultivation system for Chinese fir, carries on the discussion to the eight region on natural division, in accordance with the multiple functions of tree species, tree species such as fertile soil, barren, drought resistance of tree species of fast-growing and high-yield species, anti-air pollution species, rare and endangered species, the precious timber trees, ornamental tree species classification list each region can be mixed with Chinese fir forest tree species or in Chinese fir plantation intercropping and mixed cropping crops, vegetables, economic crops, medicinal herbs, mushrooms and green manure crops. Under different site conditions according to the site conditions, the difference in good, will be in accordance with the suitable conditions of economic tree species and forest types of forest land has been listed under the more careful division, which provides convenience and more choices for Chinese fir cultivation construction and future applications of the system.The main purpose of the construction of Chinese fir cultivation system is to increase the yield of Chinese fir, the maintenance of the ecological environment of forest land. The establishment of Chinese fir cultivation system should follow the principle of ecology, make full use of natural resources and the realization of Chinese fir plantations of fast-growing and high-yielding goal of sustainable development. A scientific and perfect cultivation system of Chinese fir should be formed by using woodland resources efficiently, combining with both short-term and long-term benefits, low investment and high returns, forest land ecological environment sustainable health, during the process of cultivating Chinese fir forest.
